Class Rules & Guides

The declared objectives of the present DNV Rules are to describe the classification/certification services applicable to the diving systems, offered by DNV Classification Society, and to provide owners and all other involved parties with with the guidance for the selection of correct level of involvement of those performing the certification/classification activities; in addition, the publication is aimed to provide a common communication platform to describe the extent of Classification activities.

The present document describes all necessary activities that shall be carried out in order for the initial diving system component certificates and class certificate to be issued by DNV. In addition to what is stated in this paper, all general requirements outlined in Part 5/Chapter 16 of the DNV Rules for Classification of Ships shall apply. The opening section of the document gives some intro and references.

The main section contains procedural requirements - classification principles, service process, documentation and plan approval, certification, classification and verification. Four appendices to the document provide some supplementary information like general description of the sub-phases of the projects, sources to assist in obtaining reference documents etc. 

The present Recommendations were developed by Russian Register and approved in accordance with current provisions and come into force since the date of publication. The Methodological Recommendations are based on the review of ISO, GOST and industry standards for fuel, lube oil and oily water analyses of particular types to ensure the compliance of testing laboratories recognized by the Register with the requirements of Annex VI to the MARPOL 73/78 Convention, IМО Resolutions MEPC.96(47), MEPC.107(49) and МЕРС.60(ЗЗ) (whichever is applicable) and other documents relating to environment pollution prevention, as well as with the requirements of the IACS, Russian Maritime Register of Shipping and industry standards for assessment of technical condition of items to be sun-eyed, regarding compliance and submission.

The Methodological Recommendations contain a large database of information on the international and national quality control standards for ship working media which permits testing laboratories rendering services for sea transport to establish a flexible system of normative documents concerning provision of quality control of ship oil products and oily waters. The information database contains standards for products to be tested, as well as for relevant testing methods including alternative ones, thus enabling not only testing and measuring equipment manufactured lately to be used, but also that traditionally applied by the thermotechnical laboratories of shipping companies in the past, with their gradual replacement by more advanced ones. The Methodological Recommendations are intended for testing laboratories, cargo owners, shipowners and surveyors.

The present publication is a completely new document - the service specification developed by the ND & DNV GL professionals with the sole intention to provide a good description of the process that is used by the ND (standing for the Noble Denton) marine services area of the world recognized DNV GL classification society, when conducting the marine warranty surveys with the purpose to evaluate if a marine operations are eligible to be accepted for the marine warranty surveys that are relating to the insurance.

This official paper deals with the MWS of both kinds - "project" and MOU/MODU-related. There are three major sections in this publication. The first section of the booklet provides the general introduction and defines the purposes. The second section provides the overview of the marine warranty survey services and general instructions on conducting of such surveys - the main deliverables, i.e. certificate of approval, statement of acceptability etc. are also mentioned in this section, together with the scope of work any limitation of approval that may be imposed.

The last section of the publication provides reference sources and some necessary explanatory notes for better understanding of the material. 

This OSS was released to describe newly offered pipe mill qualification service by DNV. Subject service is mainly based on the requirements to line-pipe manufacture outlined in the "Submarine pipeline systems" specification by this Society; qualification of the coating application may also be conducted as per the same principles with the DNV-OS-RP-F106 used for reference.

The key deliverable in the case of pipe mill and coating yard qualification is a SoC, i.e. Statement of Compliance, that is issued upon satisfactory completion of the whole qualification program. It will be valid of the date of its issuance, and will list all parameters defining the qualification scope. The verification report summarizing all DNV activities, will also be issued. It will contain the conclusion - whether the qualification was successful or not. In addition to that, this Class Society will issue a general statement of the mill/yard and the qualification project.

The today's marker for offshore pipelines requires exceptional quality. Such level of quality is set by the leading industry standards, such as the one issued by DNV, namely DNV-OS-F101. We provide excellent solutions to assist the pipe mills in proper documenting that the products manufactured by them fully meet the DNV-OS-F101 requirements.

The present CCS Guidelines provide readers with all relevant technical requirements for the issuance of the IMSBC Certificate of Fitness for Carriage; it may also be used as the reference source for the ship designers and builders, various controlling and inspecting entities, cargo handling operators, when implementing the IMSBC Code.

These Guidelines have been developed on the basis of the requirements which have been already listed in SOLAS Regulation II-2/19, chapters VI and VII as amended by IMO Res. MSC.269(85) and further define the specific requirements that shall apply to the issuance of the above stated certificate for cargo vessels. They apply to all of the vessels requesting issuance of the IMSBC Certificate. It shall be noted as necessary that the transportation of solid bulk cargo must be carried out in full accordance with all relevant provisions of the Flag Administration and any competent authority concerned; same applies to the issuance of the certificate.

In the opening part of the book providing general instructions, the classes of dangerous goods are explained. The other parts list the requirements, survey and certification matters, there is a table of minimum requirements, enhanced safety measures for transportation of cargoes prone to liquefaction, and some other supplementary information.

The plans and procedures addressed in this official publication released by CСS shall be developed in full accordance with the actual provision/arrangement of the vessel's relevant equipment; the Guidelines that have been provided by the IMO within the MSC.1/Corc.1447 are to be taken into consideration when preparing the plan, as necessary.

These plans should very clearly identify all shipboard equipment that is intended to be utilized for person recovery and all measures that shall to be taken in order to get the risk to crew members directly involved in recovery operation minimшzу to the possible level. LSA and any other type of equipment carried on board ships may be used during of the lifesaving operations to remove people from water, even if such equipment is used in unconventional way. The initiation of the recovery operations of their continuation is to be solely at the discretion of the vessel's  Captain.

The plans and procedures mentioned above shall be considered as a part of the ship's EPP (emergency preparedness plan). This booklet is intended to give the shipping industry all necessary references for complying with all applicable requirements of the international conventions that is why its content shall be studied carefully and instructions followed.

The present Guidelines were prepared by the China Class Society professionals and published with the intention to set the requirements for surveys of anti-fouling systems on vessels and ensure that vessels and applied anti-fouling coatings fully comply with the specified requirements, as applicable.

The document starts with the purpose and application explained, list of definitions used in these Guidelines, requirements for control of the anti-fouling systems applied to the vessels, CCS classification notation. The part of the book addressing surveys of ships provides general survey requirements that are to be referred to as the technical basis, tells the readers how surveys shall be requested, provide the scope for the initial and any additional AFS surveys.

The last chapter of the book deals with the anti-fouling system certificate - it sheds some light on the process of the issuance and subsequent periodical endorsements of the subject certificate, and explains the expiration dates and revalidation procedure for this document. The Annex at the end of the publication describes applicable methods for sampling/analysis of the anti-fouling systems used for protection of the ship's hull.

These Guidelines published by CCS apply to all newly built pleasure and leisure sailing crafts having not more than 24 meters in length. For the purpose of this document, the design categories of such crafts have been divided into five categories, depending on the navigation distance and wave height.

Apart from the general provisions and compliance survey information, the Guidelines address hull structure, namely its local strength, covering also monohull and catamaran type crafts, requirements to the ballast keel, masts and chainplates; stability matters have been addressed in the separate chapter of the publication. The last part has been solely dedicated by the authors to the operational requirements, such as ones applicable to the owner's manual and operation itself.

Needless to say that this document will be useful for the owners and crew members of any small leisure and pleasure craft of the length below the limit specified herein, not necessarily classed with the Chinese Register. The technical information provided in the Guidelines will be equally practical and applicable to any other craft since the physics and behavior at sea and during the calm/harsh weather would obviously remain same.
