DNV DNV-ST-N002 PDF

This standard addresses the site specific assessment of MOUs. Such assessments can be used as the basis for the Marine Warranty Survey approval of the unit at the assessed location.

The integrity of the unit in the installed condition is the responsibility of the Assured, and is subject to compliance with the assumptions and recommendations made in the site specific assessment and, where subject to Marine Warranty Survey, the recommendations given in the location approval.

The marine operations that can occur during the development of an offshore asset or when objects, including MOU’s are moved by water from one place to another are covered in DNV-ST-N001, /9/, which covers most offshore assets and operations that are likely to require MWS approval.

Details of documents that are generally required as part of the approval process are included.

Guidance note:

The operation and document type dictates the level of review by the MWS company. The following terms have been used as an indication of the level of detail:

— Documented – An in-depth document that is subjected to a detailed review by the MWS company e.g. analysis reports, procedures and operation manuals

— Submitted – A document that is provided to the MWS company in advance where the checking is limited e.g. a certificate to confirm that piece of equipment has the required capacity. In some cases this could be immediately prior to the operation but this may lead to delays if the documents are incorrect and/or insufficient.
