DNV DNV-CP-0095 PDF

This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of pourable compound for rope socketing.

This CP does not set the design requirements for the pourable compound for rope socketing. TA is based on compliance with design requirements given in the Society's rules and/or other regulations and standards. The CP describes the applicable requirements and how to document compliance with the requirements in order to obtain a TA certificate for the equipment. This includes, where relevant, technical requirements for how the type tests shall be performed.

A type approval certificate issued by the Society will cover one grade of the actual product with the possibility to include variants.

For socketing compounds this means:

grade:

one base resin

variants:

different fillers (in powder, granular or fibrous form) and additives such as accelerators and thixotropic agents to modify the resin properties. All variants shall fulfil the requirement for the same grade.

The following properties will be printed in the type approval certificate:

— compressive strength

— compressive modulus

— barcol hardness

— density or specific gravity

— heat deflection temperature (HDT)

— retention of strength after immersion in water

— curing procedure used for type testing (if relevant).

Deviation from the requirements will be stated in the type approval certificate.

A type approval certificate is normally limited to one manufacturer at one production site, however, other arrangements may be agreed upon with the Society.

Type tests as specified in Sec.2 [3.1.2], shall be carried out and verified in one of the following ways:

— at a DNV laboratory

— at an accredited and recognized testing laboratory or a laboratory accepted by the Society

— at the manufacturer’s premises in the presence of a surveyor.

The type test results shall be submitted to the Society in form of a test report according to ISO 17025 and the additional requirements for the relevant test standard for evaluation.

Application

The offshore standard DNV-OS-E304 does not require that pourable compound for rope socketing are type approved in accordance with this CP for equipment to be installed on vessels classed with the Society. TA in accordance with this CP is therefore voluntary.

A TA certificate in accordance with this CP will confirm compliance with the requirements given in the Society's offshore standard as specified in [1.1]. The TA certificate will not confirm compliance with requirements given in other parts of the rules and standards. In case additional requirements given in other parts of the rules shall be covered by the TA certificate, this shall be specified in the application for TA and will be stated in the TA certificate.
