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.

Here is the final one of the series of the competence-related standards developed and published by the DNV GL classification society and this document is dedicated to the shipboard cargo operators working on the tankers transporting the crude oil.

Such cargo operators shall be able to prepare the tanker for loading and discharge of the cargo, safely load the crude oil into the suitable tanks, ensure that the cargo intended for transportation is duly treated in the course of the transit, properly analyze the associated risks and determine the requirements for segregation, log all required data, discharge slops and vapours in the safe and environment-friendly way, efficiently strip and discharge the cargo etc. The arrangement of the standard is absolutely similar to the one of the any other personnel competence-related standard released by this classification society.

Each of the competence requirements would derive from a task to be performed by the operator. The document contains literally all information for the assessment of the cargo operators and will be very useful for the personnel willing to improve their skills associated with what is considered the scope of the standard.

The declared purpose of the Noise Code was to avoid any possible occurrence of hazardous noise levels on board vessels and also to provide required standards for an acceptable environment for seafarers. This technical document is intended to provide the owners, yards and marine surveyors with necessary guidance on how to use the IMO Noise Code, and show how to properly conduct the noise surveys; in addition, the purpose of this guidance is to provide readers with some brief description of the relevant noise parameters.

The main body of the present report provides an explanation of the applicable technical regulations within the Code. Some checklist and data tables have been provided to aid ship owners, and others, who may be willing to better understand what exactly is required from the survey and/or to witness a noise trial. The guidebook starts with some introductory information, then there is an article describing the need for the legislation that addresses the noise levels on board the vessels, and some quick review of the sound pressure levels. The following two sections provide necessary assessment conditions and noise assessment procedures, followed by the maximum noise levels and info on sound insulation. The last chapter of this document describes the procedure for the reporting on the measured sound levels.​

The present DNV standard was developed with the intention to give necessary requirements that would apply to the performance of various maritime simulator systems; the STCW convention requires that such simulators, when they are used either for mandatory simulator-based training, or as a mean to demonstrate assessment/competence, or to show continued proficiency required by the same convention, are subject to approval by the relevant maritime administration, in accordance wit the Reg. 1/12 of STCW convention.

This DNV standard hereby proposes one of the ways of carrying out above noted approval. Its purpose is to ensure that the simulations which have been provided by the maritime simulator include an appropriate level of behavioral as well as physical realism, as per the assessment and training objectives. The publication starts with a list of changes, followed by the application and certification information defining the scope of certification and listing the documentation.

The next part provides the overview of the maritime simulator equipment and instructor/assessor facilities; the other parts of the booklet address bridge and machinery operation, radio communication, handling of dry and liquid cargoes, ballast handling, safety and security, dynamic positioning, VTS operation, operation of the survival craft and rescue boat, operation of the offshore crane and ROV.

The DNV OSS is intended to present procedures and principles for the certification of tidal and wave energy converters conducted by DNV classification society. Such converters, when installed either inshore or offshore, will obviously face same environmental challenges as the converters installed on the offshore oil and gas installations. This class society will use its experience from the offshore industry to develop necessary guidance for the renewable energy installations.

That is why the reference is given to the DNV offshore standards/recommended practices and international standards. The document covers all concepts of tidal and wave energy converters and refers primarily to the near-shore and offshore concepts for such converters; however, it may also be applied to the shoreline devices. Generally, converters may be of floating or fixed types and they are usually constructed of steel, concrete or composite material.

This OSS is flexible enough to match the differences in technology and new concepts that are currently being developed, and provides a framework for proper application of the certification to the marine renewable energy. The publication contains definitions and references, safety philosophy, certification deliverables, explains the basic principles of certification as well as qualification of new technology, procedures to be followed for assignment of certification, verification of procured items, documentation and many other issues.

The present DNV specification numbered DNV-OSS-201 has divided by the authors into three major chapters. The first chapter provides general info about services offered by DNV class society and relating to the operation of the vessels on the NCS, standing for the Norwegian Continental Shelf; the second chapter of the specification gives the relevant technical design/construction requirements that would applly at the stage of new construction.

Finally, the last chapter provides the requirements for proper maintenance of NCS-related classification notations in the phase of operation. The document DNV-OSS-201 covers all NCS related classification services for the such types of offshore facilities as drilling units, storage units, production units, (and their combinations), well intervention and accommodation units; in addition, following types of installed facilities are covered - production plants, well intervention plants, drilling plants, helidecks and cranes. All technical requirements relating to the design and construction, that are provided in the present document, shall be used as a supplement to the relevant Class Requirements of DNV.

The methodology of verification described in the present specification would be applicable to the offshore units that fully satisfy the following criteria - being DNV-classed with the minimum classification notation "Drilling Unit" or "Enhanced System", and/or registered with a national maritime administration. The units and installations that were verified to comply with the relevant requirements of the document may be assigned the "Drilling Unit (N)" class notation.

This is the service specification prepared and published by DNV-GL class society to outline the alternative regulatory roadmap for the operators and owners of the FOI (floating offshore installations), FSO (floating storage units) and FPSO (floating production, storage, and offloading units) willing to engage in OCS (outer continental shelf) activities in the Mexican Gulf.

   It is based on the DNV-GL class rules and identifies the USCG requirements concerning design and equipment of such units not covered by these Rules. The specification provides a classification-based verification scheme for US compliance for the above stated types of offshore units. The first part of the specification provides general info on the principles and procedures for meeting the level of safety equivalent to the requirements of USCG, as well as legal provisions; the second part of the book provides applicable design and equipment requirements for same, consisting of the introductory part separate for each type of the unit, and compliance matrix.



   There is also informative section describing the equivalencies and other design considerations, such as passive ballast systems, external impact load on hull, fire protection boundaries, platform verification program etc. The appendix contains the Policy Letter released by the USCG.
