SECTION 1 GENERAL

1 Introduction

1.1 ObjectiveThe objective of this class programme (CP) is to describe the type approval (TA) scheme for pourablecompounds for foundation chocking.The general requirements for obtaining DNV type approval certificate is given in class programme DNV-CP-0338 Type approval scheme.The procedures and requirements described in this CP are applicable for obtaining TA certificate based onrequirements given in the Society's rules and standards, e.g.:

— DNV rules for classification – Ships DNV-RU-SHIP Pt.4 Ch.3 Sec.1 [6.1] and DNV-RU-SHIP Pt.2 Ch.3.Guidance note:This class programme is not applicable for obtaining EU Marine equipment directive (MED) certificates. Visit www.dnv.com forinformation on MED certification.

1.2 ScopeThis CP gives a description of the procedures and requirements related to documentation, design and typetesting applicable for TA of pourable compounds for foundation chocking.This CP does not set the design requirements to the pourable compounds for foundation chocking. TA isbased on compliance with design requirements given in the rules and/or other regulations and standards. TheCP describes how to document compliance with the requirements in order to obtain a TA certificate for theequipment. This includes, where relevant, technical requirements for how the type tests shall be performed.The type approval certificate for a pourable compound for foundation chocking will be valid for one grade ofthe actual product with the possibility to include variants.For pourable compounds for foundation chocking this means:

— grade: one base resin— variants: different additives such as accelerators and thixotropic agents to modify the resin properties.

The type approval certificate is normally limited to one manufacturer at one production site, however, otherarrangements may be agreed upon with the Society.Type tests as specified in Sec.2 [3], shall be carried out and verified in one of the following ways:

— at a DNV laboratory— at an accredited and independent laboratory accepted by the Society— at the manufacturer’s premises in the presence of a surveyor.

1.3 ApplicationDNV-RU-SHIP Pt.4 Ch.3 Sec.1 [6.1] require that pourable compounds for foundation chocking shall be typeapproved in accordance with this CP for equipment to be installed on vessels classed with the Society.A TA certificate in accordance with this CP will confirm compliance with the requirements in DNV-RU-SHIPPt.2 Ch.3 and DNV-RU-SHIP Pt.4 Ch.3 Sec.1 [6.1]. The TA certificate will not confirm compliance withrequirements in other parts of the rules. In case additional requirements in other parts of the rules shallbe covered by the TA certificate, this shall be specified in the application for TA and will be stated in the TAcertificate.

SECTION 2 REQUIREMENTS

1 Design requirementsThe pourable compounds for foundation chocking shall comply with the relevant requirements given in Sec.1[1.1].

2 Requirements for production and quality control arrangementThe manufacturer should have a quality system that meets ISO 9001 standards, or equivalent. If this qualitystandard is not fulfilled, the extent of type testing and assessments will be specially considered.The quality control arrangement in production will particularly be checked with respect to:

— control of incoming materials— scope of quality control, i.e. proof that test methods, test quantity and test equipment complies to theapplicable standard EN or ISO

— traceability and marking system— production records— storage condition and procedure.

3 Description of type testingThe main objective of the type testing is to verify properties which cannot be verified by analyses orcalculations with reasonable reliability, and to ensure that assumptions and conditions forming the basisfor design are complied with. This includes documenting satisfactory strength, functional capability andreliability.Extent of type testing will vary depending on previous, properly documented tests or experiences.As a minimum, type testing shall include the tests as outlined in Sec.1 [3] above.Extent of type testing may be reduced, or type testing may be waived, based on previous, properlydocumented tests or experiences.Experience data shall be documented and shall, if possible, include written statements from users.Tests which have previously been carried out at a recognised independent institution and which are properlydocumented will normally be considered and accepted as type testing.

4 Requirements for materialType approval is mandatory for chocking compounds intended for components which are dependent of anaccurate alignment, such as diesel engines, gears, steering gears, etc.The composition of resin/hardener and the design of the epoxy chocks shall comply with the epoxy maker’srecommendations including the general data/properties as indicated in Sec.1 [3], item 4.Preparatory works and pouring shall be carried out by trained specialists, authorised by the epoxymanufacturer.For class applications, detailed drawings of chocks and calculations of epoxy loading (related to componentweight, bolt pre-tensioning and operational loads) shall be submitted for approval.

5 Requirements for marking of productThe product or package shall be marked. The marking shall at least include the following information:

— manufacturer’s name and address or trade mark— production plant— product name (grade)

Section 2
