INTRODUCTION
1. The necessity of the thesis
Seaports group I, also known as group of North seaport (Hai Phong, Quang Ninh,
Thai Binh, Nam Dinh) is one of the two largest seaports group in Vietnam,in which
concentrated mainly in Hai Phong 49/67 wharves, Quang Ninh 13/67 wharves.In herethe
number of ships and cargo throughput in therecent years has always achieved a growth
rate of 9-12%/year,in which dangerous goods are hazardous and noxioussubstances
accounting for a significant proportion.The Northeastern coastal area is also an area with
high ecological value and valuable marine environmental such as Ha Long Bay, Cat Ba
Biosphere reserve, ...and always affected from maritime activities in the region.
In Vietnam, there are not many assessments and solutions to prevent pollution
from the operation of seaports (loading and storing goods), especially the operation of
seaports with loading and unloading and storing chemicals toxic.In fact, in recent years,
there have been a number of environmental incidents related to chemical storage, loading
and unloading activities in the group of seaports north vietnam and revealed many
limitations in prevention and control activities respond to this incident.
Therefore, the study of assessment on the current state, hazards identification of
causing environmental degradation and environmental risks from the loading and
unloading, storage of Hazardous and Noxious Substances at seaports North Vietnam,
then setting solution to control the process of loading, unloading and storing to prevent
and respond to related environmental incidents. It is essential to meet the actual
requirements and sustainable marine economic development strategy. Research subjects
is “Hazards of causing environment degradation during loading/unloading and storing
hazardous and noxious substances at group of seaports North Vietnam”, which is very
necessary and has new significance both in terms of science and reality.

CHAPTER 1. OVERVIEW AND RESEARCH AREAS
1.1. Research on assessing the hazards of causing environmental degradationduring
loading/unloading and storing hazardous and noxious substances at group of
seaports
1.1.1. Hazardous and noxious substances and dangerous goods
- Hazardous and Noxious Substances (HNS): oil; other liquids determined to be
toxic or hazardous; liquefied petroleum gas; liquid with a flash point not exceeding 60°C;
dangerous, toxic and harmful materials and substances transported in packages or in
containers; and solid bulk materials identified as having chemical hazards.
1.1.2. Assessment of the hazards of causing environmental degradation during
loading/unloading and storing hazardous and noxious substances (HNS) at seaports
The determination of the hazards of causing environmental degradation, related to
loading/unloading and storing hazardous and noxious substances at seaports or terminals
should include detailed assessments as follows:
- Hazard sources identification associated with HNS on site.
- For each hazard, determine the probability of causing an incident for otherHNS.
- The main damage to human and the environment due to incident occurs;
- For each hazard, define control measures;

1.1.3. Assessment process of hazard of causing environment degradation during
loading/unloading and storing hazardous and noxious substances at seaports
The port environment degradation risk assessment is followed by the basic steps
involved in industrial risk assessment process, as shown in Figure 1. 1
Figure 1. 1. Process of environmental risk assessment at seaports
1.1.4. Overview of risk assessment, hazards by criteria
1/Establishment of evaluation criteria
Evaluation criteria are factors used to determine the satisfaction of assessed object
requirements according to a certain standard. In order to establish effective evaluation
criteria, it is necessary to clearly define the factors related assessed objects and prioritize
or their importance to meet the equirements and standard.Along with that, the
identification and reasonable consideration of evaluation criteria with consensus on
evaluation indicators will form an assessment plan to provide users with a common
standard to evaluate and level of the selected subjects to be evaluated. This allows
ratings of the objects to be evaluated while also providing a fair basis for comparison.
2/Criterion score evaluation
Risk criteria include: criteria of risk classification and assessment. In which:
Likelihooddetermination
Determine the risk rating
Riskclassification

- Risk classification criteria are understood as criteria for accepting or not
accepting risks.
- Risk assessment criteria are understood as criteria to measure and assess the level
of risk, which is divided into the following 3 types:
+ Criteria for selection: risk criterions are established according to an index or
complex of risk indicators creating a tool to identify and evaluate the risk level;
+ Scoring Criteria: risk criterions are evaluated and expressed by score;
+ Random criteria: Criteriasare selected according to statistical, probability
methods to measure the compliance with each determinedobject and field .
1.2. Overview of research works
1.2.1. Studies in the world
There are many studies on the environmental impact from the process of
transporting dangerous goods by sea in the world. The studies focus on the following
issues: (1) Risk assessment of the process of transporting dangerous goods by statistics of
related accidents; (2) using modeling methods to evaluate physical-chemical properties
and simulate chemical metabolism as well as potential hazards to the ecological
environment;(3) Develop an analytical framework for risk assessment and guidelines for
risk management in the transportation of hazardous goodsby sea; (4) Establishment a
plan to prevent and respond to environmental incidents related to transportation of
hazardous goodsby sea.
Studies in the world are a very useful scientific basis and experience for Vietnam
in the process of researching and assessing the risks of environmental degradation
during transportation, loading/unloading and storing hazardous and noxious substances
at seaports.
1.2.2. Domestic studies
In Vietnam, the issue of environmental impact caused by maritime activities is
also concerned by scientists and management agencies. However, the research is mainly
assessing current environmental status and completing the legal system on environmental
management. Research directions related to this field include: (1) Identify sources of
emissions from maritime activities (ships, seaport operations) and assessment. (2)
5
Studying to assess the hazards of causing oil spill from maritime activities and to develop
prevention and response plans;(3) Research on environmental risk zoning in coastal
areas.
Studies on environmental impact assessment from shipping activities have mainly
focused on oil spills, while very few studies have assessed the hazards of causing
environmental degradation related to transportation of hazardous goods by sea. Some of
the relevant original research performed by postgraduate.

shown that: group of seaports in the Northern mainly concentrated in Quang Ninh and
Hai Phong is a national general seaport, regional focal point (types I and IA) and have
63/67 in this group. Statistics of goods transporting by seaports in the Northern. Shows
that volume of cargo is mainly focus at Hai Phong seaport (57.4%) and Quang Ninh
(42.3%) and small percentage at Thai Binh and Nam Dinh seaport accounts for (0.3%)
and mainly bulk.
1.3.2.Loading/unloading and storing hazardous and noxious substances at seaports
a) Methods of hazardous and noxious substances transportation by sea
HNS can be shipped by two ways: (1) bulk (liquid or solid in bulk) or (2) packaged
form.
b) Methods of HNS loading/unloadingat seaport
Classified into 4 types:
- Liquefied gas port
- Liquid cargo port in bulk
- Bulk cargo port
- Container port
c) Storing HNS at seaports
Cargo storage is the process of preserving goods, packing/unloading goods in
bags/bales/containers within the boundaries of the port.
- Methods of HNS storingat seaport:
- Stored directly outdoors

1.3.3.2. Main hazards of causing HNS transportation by sea
- Flammability: An HNS fire can lead to the release of heat, dust and toxic gases.
- Explosiveness: Explosions can be accompanied by shock waves, fire and heat to
damage;
- Oxidative properties: their composition contains oxygen readily decomposes by
which they provide oxygen to burn other materials;
- Toxicity: Substances that cause death or injury to living organisms at low levels
if inhaled, ingested or absorbed through the skin.
- Corrosion: Substances that can irreversibly destroy or damage surfaces or other
substances they come into contact with.
8
- Irritant/harmful: Substances can be harmful to health while those with irritating
properties can cause reactions with skin (dermatitis) and mucous membranes in living
organisms.
- Reactivity: Chemicals can react with neighboring materials, fuel oil, water or air
in a variety of ways, including corrosive, decomposition, oxidation/reduction or
polymerization .
- Effects on marine resources: The impact of one or more chemicals on the marine
environment depends on several factors. The most significant is the toxicity of chemicals
or mixtures of substances in the environment.

In the implementation, the postgraduate has conducted 3 main surveys to collect
information at the relevant units: Phase 1: (November 2017); Phase 2: (in 2018); Phase 3:
(March 2019). In addition to actual survey to collect actual information at seaports,
information is also collected by email between postgraduate and representatives of
management units.
- Methods of analysis and synthesis: This method is used to analyze the
characteristics of HNS, seaports activities related to HNS and accidents related to HNS at
seaports. Hazardsources aggregate caused by during loading/unloading and storing
hazardous and noxious substances, characteristics of accidents involving HNS in research
area.
- Method of collecting secondary information: In this study, secondary information
related to the volume of goods through the port, accidents, maritime incidents, data on
environmental status, current management status at the seaports… are collected from
publicly available sources.
- Descriptive statistical analysis method: is used to analyze the collected data
related to the loading and unloading and storage of HNS at seaports and the incidents that
have occurred to make recommendations. trends and identify hazards of causing
environmental degradation.
10
- SWOT method :
In this study, the SWOT method is used to analyze the strengths and weaknesses of
seaport management system HNS; analyze opportunities and challenges in managing
risks during loading/unloading and storing HNS at seaports.
2.2.1.2. Methods and techniques for analyzing assessment risks and recession
1/Binary screening method:
This method uses a "Yes" and "No" algorithm to classify seaports that storing and
loading/unloading HNS.
2/Checklist method:
The checklist is a list of hazards, risks or errors occurring in controls. Usually, this
method is built on experience and results of previous risk assessments or past mistakes.
3/ Method of preliminary analysis of hazards:
This method is suitable for assessing the risks of environmental degradation during
loading/unloading and storing HNS due to this method can be implemented when
information is limited and allows for early consideration of risks in the chain of
operations.
4/ Hazard assessment method
The hazard assessment process consists of 5 basic steps including:
- Information gathering (identification of hazards)
- Hazard assessment
- Develop risk strategy
- Select and implement a method of hazard control
- Hazard review and hazard control measures
5/ Method of evaluation by criteria
To determine the risk value and the extent of degradation for a chain of related
activities, it is possible to use the criteria to evaluate. With each hazardsource must to
indentify possibility and extent of the deterioration are determined through the criteria
with specific indicators assessing the level of risk and the degree of degradation by a
11
scale of 1 to 4 corresponding to the level from "low" to "very high" of risk degradation
and from "Negligible" to "Very serious" of the degree of degradation.
6/Multi-criteria analysis method (AHP):
This method is used to form a matrix that compares risk criteria combined with
expert method (Delphi) to determine priority cost-weighted of each criterion in the
process of risk analyzing degradation of seaports.
7/Delphi Method: This method supports to collect information and knowledge
from a team of experts for questionnaires or assessments of a problem. this method is
approach to consensus through questionnaire submissions.
8/ Scoring method:
The scoring method is a technique to quantify by score the parameters of the
consumption indicators to evaluate specific criteria in the set of risk assessment criteria.
Điểm số đánh giá ứng với mức độ rủi ro hay mức độ thiệt hại của mỗi tiêu chí. The rating
score corresponds to the level of risk or damage of each criterion.

CHAPTER 3. RESULTS AND DISCUSSION
3.1. Reality and environmental impacts during loading/unloading and storing
hazardous and noxious substances (HNS) at group of seaports North Vietnam
3.1.1. The status of loading/unloading and storing hazardous and noxious substances
(HNS) at group of seaports North Vietnam
According to the announcement of the Vietnam Maritime Administration in 2020,
the group of Northern seaports has 67 seaports, including 14 container berths, 12 liquid
cargo berths, 33 general cargo berths.
Currently, Vietnam has no official statistics on the amount of HNS passing through
seaports. According to the survey results at the seaports North Vietnam shown that:
- 12 berths: loading/unloading liquid HNS in bulk,
(petroleum, liquefied petroleum gas, liquid chemicals).
- 14 berths: container loading/unloading HNS accounts for about 1.05% - 1.25%
of container cargo for Hai Phong area and 0.45% - 0.65% for Quang Ninh area .
- 4 general berths have loading/unloading HNS, in which dry HNS account for a
negligible amount (only Hoang Dieu seaport, DAP seaport loading/unloading bulk HNS).
3.1.2. Incidents and waste sources related loading/unloading and storing hazardous
and noxious substances at group of seaports North Vietnam
According to data from the Vietnam Maritime Administration from 2010 to 2019,
the seaport North Vietnam recorded nearly 100 maritime accidents, equal to an average
of 1 case/year of accidents related to HNS. In which, mainly fire and explosion in the
process of loading/unloading goods at the port.
Details as below figure Error! Reference source not found.
13
Figure 3.1. Detailed incidents for each seaport at group of seaports North Vietnam
However, the above data only records accidents during loading/unloading not
during storage relaved HNS. Statistics of the authorities on fire prevention and
environmental protection also did not record incidents during the storage of HNS.
through investigation and survey at seaports, only a few small accidents did not cause any
damage to health and the environment.
In addition, the loading/ unloading and storage HNS at seaports also generate a
large amount of waste such as packaging, waste water from cleaning process of loading/
unloading vehicles, crates and containers containing chemical. If is not well managed,
these types of waste will also be a source of pollutants environmental degradation in the
seaport area.
3.1.3. The status of environmental at seaports North Vietnam
Currently, there are no studies to evaluate the specific contribution of seaport
operations in general and loading/unloading and storing HNS at group of seaports North
Vietnam to environmental degradation in coastal areas.
From the results that have been studied on the actual situation of environmental
quality in at group seaports North Vietnam, it shows that the seaports at Hai Phong -
Quang Ninh, environmental quality is under great pressure from business activities.
socio-economic status and is being degraded, showing signs of pollution by a number of
parameters such as dust (air), oil and grease content, ammonium, nitrite, phosphate and
TSS, coliform (water), heavy metals, polycyclic compounds (sediments). The sources of
pollutant emission into the environment of Hai Phong - Quang Ninh seaport area are very

diverse, including: daily life, industry, agriculture, traffic... in which maritime activities
contribute a significant proportion caused polluted.
The environmental quality at Thai Binh – Nam Định seaport is too. Environmental
quality is not under much pressure from socio-economic activities such as Hai Phong -
Quang Ninh area. The level of degradation and pollution is not high. This is consistent
with the development of pollutant emission sources, including maritime activities in the
Thai Binh - Nam Dinh area.
3.1.4. The status of environmental management during loading/unloading and storing
hazardous and noxious substances at group of seaports North Vietnam
a) Strengths
- General awareness of marine environmental protection: Environmental protection
in general and marine environment protection in particular has been paid attention and
invested by the Party and State. The objectives of environmental protection are
specifically integrated in the Party's national development guidelines and guidelines,
strategies, policies, sectoral and local development plans. The deepening international
integration and cooperation in the maritime sector also contributes to raising awareness
about environmental protection in maritime activities in Vietnam.
- Legal system: The regulations on environmental protection during
loading/unloading and storing HNS are fully reflected in the laws: Law on
Environmental Protection, Law on Chemicals, Law on Maritime, Law on Fire Prevention
and Fighting and guiding documents. Vietnam also promulgates national regulations and
plans on oil spill response, Regulation on chemical incident response, implementation
plan on monitoring, risk assessment, remediation and settlement. Consequences of oil
and toxic chemical spills at sea in the period 2018-2020. Vietnam is also a member of the
International Maritime Organization (IMO) and participates in more than 20 international
conventions in the maritime field, many of which are related to environmental protection
by sea in general and dangerous goods transportation in particular... in addition, Vietnam
has also signed bilateral agreements with neighboring countries on coordination in
response to maritime incidents at sea.
- Management apparatus: The system of state management agencies in charge of
transportation management, environmental protection and chemical safety has been
15
completed from the central to local levels and related sectors and units. The seaport also
has a safety and environment department. Compliance monitoring agencies are also well
organized and operate more professionally.
- Science and technology: Modern technologies in transporting loading/unloading
and storing goods are being applied strongly at Vietnam's seaports. All seaports have
been appling information technology and high automation during loading, unloading and
storing goods. This will help to control HNS closely and reduce risks.
b) Weakness
- Weak environmental protecting infrastructure: scale of seaport in Vietnam: are
smaller than some countries in the word. In Vietnam, due to the characteristics of
management and operation seaport consisting of many ports managed and exploited by
many different investors, the infrastructure for environmental protection less synchronous
investment. e.g. waste, environmental incident response infrastructure, pollution control
system, waste treatment system from seaport operations….
- Lack of human resources: At most seaports, the state management agency in
charge of navigation lacks human resources with expertise in environmental safety,
especially expertise in the management of HNS as required by IMDG Code. Incident
response units lack personnel with expertise in responding to incidents involving HNS.
- Lack of regulations and standards guiding the safety during transporting;
loading/unloading and storing HNS at group of seaports: Seaport must be applied IMDG
Code's guidance. However, due to the lack of regulations national (specialized QCVN)
on safety of transporting; loading/unloading and storing HNS, lack of qualified human
resources, so the application is not enough.
- Weak coordination: The control of dangerous goods at seaports is still not
effective due to the lack of coordination between the Maritime Administration and the
local environmental management agency and the chemical safety management agency.
- Financial sources: The investment in infrastructure for environmental protection,
incident prevention and response in maritime activities requires huge funds. Meanwhile,
funds for environmental protection activities is quite limited in Vietnam's seaports. It not
meet the requirements of environmental protection. The proportion of fully equipped
16
equipment and environmental protection systems and response to environmental incidents
is still low.
c) Opportunity
- International cooperation: Maritime activities are international activities, so
joining international maritime conventions and bilateral and multilateral cooperation in
this field is an increasing. Participation in international conventions will be an
opportunity for Vietnam to improve capacity in environmental management and response
to incidents.
- The development of technology: The development of science and technology,
especially automation helped the process of loading/unloading and storing HNS. It is
also helps to effectively manage.
d) Challenge
- The development of the seaport system and the increase in the volume of goods
in the world requires to develop very quickly of the vietnam and international seaport
system to meet the increasing. The increase in the volume of seaports goods in general
and HNS in particular will increase the hazards of causing environmental degradation
during loading/unloading and storing HNS at seaports.
- The requirements for environmental protection in IMO are increasing lead to
more investment funds for environmental protection, prevention and response to
environmental incidents of seaports.

Figure 3.2. Graph of The hazard of environmental degradation of each port
The results of environmental risk assessment and degradation at ports with during
loading/unloading and storing HNS at group of seaports North Vietnam showed that:
There are 6/30 berths are high risk, 24/30 berths are medium risk and no low risk port.
The common characteristics of high pollution risk group is with out management
and controling process during loading/unloading and storing HNS, lacking equipment
and highly automate not yet… the port is located in the inner city, densely populated, has
high traffic density and has many socio-economic activities.
Analyzing and evaluating in detail set of criteria for risk assessment of
environmental degradation at Hoang Dieu Port is shown that: loading/unloading and
storing HNS activities has priority targets to overcome including:
- Technology, equipment, warehouse: I6
- Goods management process: I10
- Technology and equipment for loading and unloading: I5
- Plan, measures to prevent pollution and respond to incidents: I11
- Infrastructure system for environmental protection and prevention and UPSC: I4
- Organize training for workers on safe loading and unloading HNS and UPSC: I12

3.4. Proposing solutions on management of HNS and guiding establishment plans to
prevent and respond to chemical incidents at seaports
3.4.1. Develop regulations on management of HNS for seaports
Regulations and technical guidelines for HNS transport by sea specified and
detailed in the International Maritime Dangerous Goods Code (IMDG code) and are
updated by the Protocols. However, terminals need to chance these guidelines to specific
management relevant to operations.
3.4.2. Guidelines for risk assessment during loading/unloading and storing HNS
Step 1: risk identification
Based on assessment criteria and risk indicators environmental degradation, each
port identifies risks in its operations and establishes a list of risk criteria.
Ports can supplement or separate risks if necessary
Step 2: Risk Assessment in port operations for each criterion
Using the criteria score assess for each risk criterion during the loading and
unloading and storaging HNS according to instructions. Experts combine with safety and
environment managers at the port to conduct assessment and then take the average score.
Step 3: Set remediation priority based on risk assessment score
Based on the risk assessment score of each identified criterion, establish a table of
priority order of criteria to be overcome based on the order of risk hierarchy from high to
low.
3.4.3. Plan to prevent and respond to environmental incidents in during
loading/unloading and storing HNS at seaport
Pursuant to current regulations of Vietnam’s law on fire prevention and fighting;
Responding to oil spills and chemical incidents, facilities must plans and measures to
prevent and respond to environmental incidents.
The main contents of a plan to prevent and respond to chemical incidents at
seaports include the following:
- Information related to loading/unloading and storing HNS at the seaport
- Forecast of risks and incidents
- Preventive solutions
22
- Chemical incident response plan
- Prepare capacity to respond to chemical incidents
- The plan to overcome the aftermath of a chemical incident
- Training plan and training on incident prevention and response contents.
- Process and organization of force to respond to chemical incidents at seaports
CONCLUSION AND RECOMMENDATION
1. Conclusion
Risks of environmental degradation during loading/unloading and storing HNS at
seaports include fire and explosion, oil spills, release of toxic chemicals and
combinations of these hazards. The sources of these risks identified include: The
infrastructure; technology and equipment; scale and type of seaport operations and
management activities. The set of criteria for risk assessment and environmental
degradation during loading/unloading and storing HNS at seaport was developed,
including 4 risk criteria divided into 14 specific criteria and 2 high level environmental
criteria degradation with 5 indicators. Each risk assessment criteria is cost-weighted and
the assessed criteria according to a risk scale. This is the first set of developed criteria to
assess during loading/unloading and storing hazardous and noxious substances at group
of Vietnam seaports. The criteria and criteria for risk assessment of environmental
degradation of proposed criteria in this thesis are similar to the the IMO safety
assessment guidelines for maritime operations. The importance and evaluation of the
criteria are consistent with the safety assessments in seaport operations by studies around
the world.
The set of criteria is applied to assess the hazards of causing environmental
degradation for 30 seaports during loading/unloading and storing HNS at group of
seaports North Vietnam. There are 6 high-risk; 24 medium-risk and no low-risk berths.
Each berth of risk degradation is also specifically identified and issues to be overcome
are proposed. Each berth of risk degradation is also specifically identified and issues to
be overcome are proposed. This is the first time seaports North Vietnam have been
assessed and graded and identified management; technical limitations to be overcome to
minimize the hazards of causing environmental degradation during loading/unloading
and storing hazardous and noxious substances at group of seaports.
23
Based on the results of identification; assessment and decentralization of
environmental degradation as well as limitations in management and technical
infrastructure, the proposed management solutions include:
- Develop regulations on management of HNS at seaports including 8 contents: 1)
Regulations on HNS through the port, 2) Declaration and receipt of information of HNS,
3) Updating and storing information on HNS, 4) Procedures for transporting during
loading/unloading and storing HNS and preserving at seaport, 5) Safety instructions
during loading/unloading and storing HNS at the port, 6) Responsibility for parts in the
chain of loading, unloading, preserving, delivering and receiving HNS, 7)
Troubleshooting related to HNS, 8) Regulations on professional training and safety
training;
- Guidelines for risk assessment during loading/unloading and storing HNS (by set
of criteria) in three steps: 1) Hazard identification, 2) Risk assessment in port operations
to each criterion, 3) Set remedial priority based on the risk assessment score.
- The plan for prevention and response to environmental incidents during
loading/unloading and storing HNS at seaports follows three issues: 1) Determining
subjects to be planned, measures to prevent and respond to environmental incidents
during loading/unloading and storing HNS at seaports, 2) Plans for prevention and
response to chemical incidents at seaports, 3) Procedures and organization of force to
respond to chemical incidents at seaports.
If the above proposed solutions are implemented, it will help the ports better
manage during loading/unloading and storing HNS as well as reduce the hazards of
causing incidents; environmental degradation from operation.
2. Recommendation
Vietnam's seaport system is being planned towards zoning and grouping ports
according to each type of loading and unloading goods and tonnage of ships associated
with infrastructure and loading and unloading technology. The research results of the
thesis need to continue to improve on the legal basis, add more data in seaports so that it
can be used as a basis for re-planning the functions of seaports North Vietnam.
Accordingly, HNS will be loaded and unloaded at berths that have sufficient safe
conditions during loading/unloading and storing. It is lowest hazards of causing
24
environmental damage. The proposed solutions of the thesis are also the scientific basis
for relevant authorities to issue specific regulations and guidelines suitable for seaport
operations.
The research direction of the thesis needs to be continued for seaport regions and
other groups in Vietnam in order to perfect the theoretical and practical basis as well as
the data system in developing a set of assessment criteria hazards of causing
environmental degradation due to during loading/unloading and storing HNS in particular
and a set of criteria for assessing the hazards of causing environmental degradation of
seaport in general. From there, it can be expanded and applied to groups of seaports
nationwide.
