The DNV Standard no. DNV-DS-E403 includes following chapters - General Information; Surface diving systems - Design philosophy and premises; Pressure vessels for gas storage, human occupancy, and other purposes; Life support systems including piping, valves, hoses, fittings, umbilicals and compressors; Electrical systems; Fire prevention, detection and extinction; LARS - Launch and recovery systems; Instrumentation and communications; Evacuation systems; Selection of safety objective.

The declared objectives of the present standard were to give the guidance and applicable criteria on the design, manufacture, installation and testing/commissioning of the surface diving systems that employ air or nitrox as the breathing medium. It shall provide the standard of safety for such system that would be internationally acceptable, by means of defining the minimum requirements to the design/manufacture, installation and operation/maintenance and repair of these systems; it shall also serve as a technical reference book for classification and verification, as well as to assist in contractual matters between contractor and purchaser of the diving system; the standard can also be treated as a good guidebook for the designers, contractors and buyers of the above mentioned equipment.

The Annex V to MARPOL Convention entered into force on 31 December 1977. But, some of the recently conducted surveys revealed the facts that some garbage is still disposed of to the sea from the ships. And plastic garbage accounts for the largest single item found. Then, IMO revised this Annex and it's revised edition entered into force on 1 January 2013.

The present Guidance Notes were officially released by Lloyd's Register of Shipping with the intention to make the requirements of the subject Annex earlier to understand and, consequently, to comply with. It is obvious today that the garbage thrown from the vessels can be deadly to marine life in the same was as oil or chemicals. The maximum danger comes from plastic stuff since plastic can float for years and get swallowed by fish or marine mammals mistaking it for food; in addition to that, fish can easily become trapped in plastic bags, nets and ropes. And, while some of the garbage comes from the people on land, significant part of it comes from vessels.

Of course, many items will be degraded by the sea water; however, this is a very time consuming process - it can take months or even years, and, again, plastic is the worst one - it would take about 450 years to get it degraded by sea...

Official release by Japanese Class Society, Nippon Kaiji Kyokai (ClassNK). It has been meant for ship masters and is intended to let them easily check whether their ships are kept in seaworthy and safe condition at any given time. When correctly applied and followed, this set of checklists will play a good role in providing the proper control over the maintenance of the vessel and, subsequently, make shipping safer.

Since the very first release of this booklet was published in 1994 and amended in 1996 to include the updates on the maintenance standards, significant number of comments and new ideas were received from the ship owners and other parties involved. The present edition of the Guide was prepared by NK Class Society based on those ideas and comments as well as NK database of detained vessels. Ship owners and crew members are expected to make all necessary arrangements for proper maintenance of the ships and make sure their ships are kept in a safe and seaworthy condition.

The authors hope that this Guide will be useful for the Masters and owners as the information contained in it is very practical and may contribute in proper maintenance and operation of the vessel; the checklist provided therein may be used not only for the official checks but also for the routine verification.

Offshore Service Specification no. DNV-OSS-302 is dedicated to the Offshore Riser Systems. It was released by Det Norske Veritas in October 2010 and remains the latest edition of the document. It was last amended in 2012 and all changes have been reflected on page 3 of the Specification. The document consists of three major parts - General, Technical Approach, and Service Overview.

As one of the leaders in the classification, DNV provides the offshore industry with services relating to the dynamic riser systems. In this definition, "dynamic" means non-stationary riser. Metallic and composite risers, umbilicals, flexible pipes and loading hoses are included in the "dynamic riser systems" notation. The main objectives of this OSS are to describe the overall competence and experience of DNV Class Society relating to such systems, and to describe the technical advisory, verification and certification services offered by DNV for dynamic riser systems.

This OSS is used by DNV as a reference when preparing proposals to the Clients, providing a clear understanding of the scope of work to be done. The document itself consists of three major sections supplemented with two appendixes...

Here is another DNV GL standard - in this one the authors intend to focus on the shore-side personnel engaged in the marine transportation of various dangerous goods as described in the IMO IMDG Code.

In particular, the present official standard is specifying relevant competence requirements that have been covered in the IMO IMDG Code concerning the principles of classification of such goods, their packing and marking, placarding and labeling, packing/unpacking of cargo containers with the dangerous goods inside, preparing transportation documents for these goods, making decisions concerning offering/accepting of the various dangerous cargoes for transportation on board the ship, handling dangerous goods and preparing the loading and stowage plans, loading/unloading dangerous goods into or from the vessels, carrying dangerous cargoes in transport.

It shall be noted as necessary that national requirements that are applicable to the transportation of such sort of goods other than by sea, i.e. by road/railway/inland waterways have not beeт not addressed within the present document. Plus, it shall further be noted that this publication is primarily meant to specify competence requirements over and above those covered by any of the relevant requirements that are imposed by national and/or international legislation.​

The present official Guidelines released by Chinese Class Society relate to a bulk carrier type of ships and are focusing primarily on the survey procedures of CCS; however, they may also be very useful when applied in conjunction with examination/inspection schemes of any other regulatory organization body, vessel owners and operators, crew members etc. due to the information contained.

The contents of the booklet as follows - Introduction; Ship type introduction of bulk carrier; Hull structural survey of bulk carrier; Special requirements for bulk carriers; Structural details failures and their repairs; Criteria for local strength. The present guidelines are developed to provide the interested parties with the info related to the assessment and survey, as well as repairs to various structures of the ship's hull. The structural failures and their potential causes are also addressed in the book, supplemented with the examples of such damages. The survey points to be taken into consideration by inspectors have also been covered.

The recommendations provided in the Guidelines are based on the collected relevant data. As usual, figures, tables and images are supplemented the text part of the document for better presentation and easier understanding of the requirements applicable to the bulk carriers.

The Guidance for Implementation of Statutory Surveys prepared by Chinese Register of Shipping is divided into two parts. In the first part contains Notes to Modifications, Preamble and Interpretations of IMO Conventions and Codes - SOLAS, Load Lines, MARPOL, Tonnage Measurement, HSC Code, BCH/IBC Code, IGC Code, PASSUB, FTP Code, COLREG, and others.

In the second part of the Guidance the administration data, status of ratification of conventions, and additional requirements of flag states are stated. It is quite obvious that critical attention shall be paid to the correct implementation of the statutory requirements since any failure to do so will immediately result in the vessel being detained by port state authorities. The recommendations provided within present Guidance released by CCS will definitely be very helpful in making decisions affecting statutory certification.

The book is to be used by crew members of the ships that have been classed with Chinese Class Society; at the same time, the information contained in it, will be equally useful and important when applied to the ships classed with other Societies, as well as ship owners, operators and any other involved parties.
