Sec.1. Introduction –

1. Introduction

1.1 Preamble

This Recommended Practice (RP) outlines the general best practices that lead to effective testing andcommissioning of marine and industrial systems onboard mobile offshore units in newbuilding projects. For convenience, an extract of all DNV rules related to testing and commissioning of marine and industrial systemshave been included in this document. It should be noted that for more accurate applicable statutory and classrequirements related to testing and commissioning, applicable versions of the statutory and class rules asspecified in the contract shall be referred to. System categorizations included in the appendix are general innature and may not include all applicable systems that are specific to particular newbuilding projects and so,this document should be used only as a guide. This document currently includes requirements related to drillingunits with the intention to include requirements related to other object types at a later stage.

1.2 GeneralDNV has recognized that the technical complexity of modern Offshore Installations is increasing due tosystems becoming more complex, more automated and more tightly integrated. This evolution providesdesigners, shipyards, owners and other involved parties challenges in the management of testing andcommissioning equipment and systems onboard offshore units successfully.

1.3 Objective

Sec.2. Commissioning Process and Definition of Various Stages –

2. Commissioning Process and Definition of Various Stages

Commissioning of an offshore unit is a time consuming and complex process. A structured approach is anecessity for a successful commissioning phase of the newbuilding projects. While the requirements for thetesting and commissioning are clearly specified in various applicable DNV standards, how exactly thecommissioning activities should be carried out is largely left to the Builder/Owners of the mobile offshoreunits. For instance, there will be dependencies between the different packages. It is, however, a DNVrequirement to see that the testing requirements mentioned in our rules are carried out during commissioning.It is often required by DNV offshore standards that the equipment is to be tested in “as installed” condition. So,

though similar tests have already been carried out during a factory acceptance test (FAT), a new test in installedcondition would be required., A typical example could be the offshore cranes. They will probably be overloadtested during FAT, but they will still be required to have an overload test in installed condition.

Before commissioning starts the responsible DNV surveyor and all stakeholders involved in preparing andcarrying out the testing and commissioning should also have an idea as to what activities are considered mostimportant to DNV and also what activities are not within the DNV scope. During commissioning it is alsoimportant to be aware that the owner’s and the yard’s viewpoint as to what is DNV’s scope of work may not

be in harmony with the scope required by the DNV Offshore standards. It is also important to recognize thatowner/yard may have additional requirements e.g., related to performance or additional functionality, that may

be over and above the classification requirements of DNV.

2.1 Detailed design

When entering into the final stages of any project, the detailed design is expected to be fully completed,reviewed and approved. Failure to complete the design in a satisfactory manner may undermine alreadycompleted testing and commissioning, especially comments that may result in redesigning component or systems. Any duplication in redoing testing and commissioning is not very efficient and will result in loss of




Sec.3. Pre-commissioning –

cabling, electrical equipment, etc. have been demonstrated as physically complete. Dynamic tests are limitedto non-energised tests like cold alignment of shafting for motors, engines and generators. Further megger tests,flushing and drying of piping systems, cleaning, etc. is included in this milestone. Typically, the MC will result

in a number of punches that must be rectified before any actual pre-commissioning, testing and commissioningcan commence. Normal findings typically include missing electrical equipment grounding, lack of proper shielding of fuel pipes or hot surfaces, insufficient nozzle coverage for deluge systems, etc. The evidence of the required certification of equipment should be verified during mechanical completion stage so that there areno surprises before commencing pre-commissioning, testing and commissioning stages. Failure to do so may

jeopardize the safety of such activities.

3. Pre-commissioning

Pre-commissioning is the stage before commissioning which involves the verification of functional operabilityof the equipment part or full systems. This stage of testing requires energising of equipment and introduction of fluids in fluid piping systems. This is the stage where the vendor and/or the yard are carrying out independenttesting of the equipment/system. This is a “trial and error” phase where class normally do not attend. Duringreview and approval of commissioning procedures, it is important for the DNV surveyor to make sure that testsrequired by the rules are carried out during the commissioning phase. It may be a challenge when the testsrequired by the rules are carried out during pre-commissioning but not attended by a DNV Surveyor. This should

be highlighted during the review of the commissioning procedures. Pre-Commissioning would typically include:

— Loop testing. — Motor no load runs.

— Equipment final alignments.

3.1 Commissioning

The phase after mechanical completion, pre commissioning and testing is often referred to as thecommissioning phase. The “commissioning of an an offshore unit” is a very wide term and for the purpose of classification, it refers to equipment or system commissioning. Typically equipment/system commissioning

will consist of: — Functional testing of systems by start-up priority.

— Testing of ESD/PSD and F&G.

— Load tests and other equipment performance testing.

In the commissioning phase it will be verified that the installed equipment and system are working as intendedand that the rule requirements for the various equipment/system functionality are met. The rules will haverequirements for “performance”, e.g. number of starts for starting air receivers and “functionality”, e.g. safetyfunctions of boilers and incinerators.

For effective commissioning, it is important that the testing and commissioning of the different skids/packagesare given the right priority so that they happen in the right sequence/order. Very little commissioning can be

performed without the hydraulic ring line, power system, cooling water, pneumatic systems and other utilities being functional and working properly, Typically, temporary arrangements should not be accepted for commissioning. It should also be a general principle that commissioned equipment is not dismantled or modified after testing and commissioning of the equipment/system is completed. Once the equipment/system




Sec.4. Commissioning Procedures –

3.3 Marine sea trial

The marine sea trials typically focuses on propulsion, steering and utility systems functioning under normal

operating conditions. A prerequisite for sea trials is that the major safety systems like fire fighting, life-saving

appliances, PA/GA, HVAC, etc. are satisfactorily commissioned ahead of sea trials. In addition, the inclining

test should be completed prior to taking the unit out on sea trial.

Sea trials are conducted to test a vessels performance and general seaworthiness. Testing of a vessels speed,

manoeuvrability, equipment and safety features are usually conducted during sea trial. However, this

demonstration of speed and manoeuvrability, etc. is normally more important for a merchant vessel than an

offshore unit. A merchant vessel will typically have a contract speed as part of the contract between the builder

and the owner. That is seldom the case for an offshore unit. The marine sea trial will typically consist of but

not limited to:

— Testing of Dynamic Positioning System.

— Final commissioning of Ballast systems, Cooling water, Lube oil, Fuel Oil, HVAC, Thrusters, etc.

— Speed test.

— Crash stop.

— Turning test.

— E0 test.

— Endurance test.

The marine sea trial is normally not relevant for fixed units or units without propulsion.

3.4 Delivery

Depending on type of unit, the successful completion of all testing and commissioning activities will trigger

the delivery of the unit. The level of completion will however vary from project to project. Typically a project

with a contract in place and a long transit to the operation area, the owner may prefer an early delivery with the

intention to close some of the outstanding items in transit. If a unit does not have a project in place, the owner

will typically aim for a higher level of completion before they will accept the unit. Equipment subject to classapproval that is not readily commissioned in accordance with approved testing and commissioning procedures

should be identified in the delivery documentation by issuance of relevant conditions of class. It should be

evaluated prior to delivery whether the outstanding class and statutory systems are minor in nature and does

not affect the safety and integrity of the unit that will allow the Class Society to issue appropriate Class and

Statutory Certificates. If critical systems e.g., fire fighting/detection, propulsion and steering, life-saving

appliances, navigational aids, etc. are not commissioned, Class and Statutory Certificates are not typically

issued.

3.5 Hook up

Hook up is mostly relevant for fixed units like FPSO’s and other units that will stay on the same location for a

number of years, however some drilling units may require some testing of systems on first location. Typically

it means the hook up of risers to the unit and preparations required prior to first oil. Many of the vital

commissioning activities for such units will have to take place at location and cannot be completed during the

- Marine System xxxx

- Topside – Service System xxxx — Ad item 1.2 System integration testing

The integral system is controlling several systems and their functions from a common operating systemVDU. The Integrated Control and Monitoring (ICMS) system is built for the specified type of vessel whichis a distributed monitoring and control system which, due to its flexibility and modular architecture can beextended to cover a wide range of applications and types of vessels.Integration testing is defined as testing of more than one system, i.e. testing that extends the work

performed in a single commissioning procedure and typically involves systems or equipment covered inanother commissioning procedures.

— Ad item 1.3 Pre-requisitesDescribe the systems required to be completed prior to start activities as listed in this procedure. — Ad item 2.0 Objectives

The objective of an integrated test procedure is to verify the necessary check and pre-requisites areaccordingly carried out and that the system is in accordance with design specification and regulatoryrequirements.

5. DNV Involvement in Commissioning

DNV’s involvement in testing and commissioning is limited to the requirements of statutory and class rules.DNV surveyor will attend testing and commissioning to the extent specified in applicable Quality SurveyProgram (QSP).

Survey scope shall be categorized as follows:

— Survey Category 1 - Statutory and Essential Systems for Safety (normally increased attendance by DNV). — Survey Category 2 - Main Systems / Functionally Important (For Main and Additional Class Notations,

extent is based on the yard’s experience and the effectiveness of Yard’s QA/QC system). — Survey Category 3 – Normally limited or no attendance required by surveyor.
