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...
The publication presented to your attention presents the Rules developed and released by DNV classification society and addressing the FPS units and installations, stating the conditions and procedures used for the purpose of assigning and maintaining the classification status.
The publication consists of three parts providing general info on the basic principles of classification and procedures in use, the requirements relating to the design and construction for the phase of the newbuilding and, finally, requirements applicable to the maintenance of class status during the operation of the unit. The Rules apply to the offshore installations of the ship-shaped, column-stabilized, self-elevating, tension-leg and deep draught types utilized for the hydrocarbon production, loading, storage and offloading services.
There are some special considerations for conversions contained in the the first appendix, while the other two appendices provide the intro to the offshore classification and guidance on the mooring equipment acceptance standard. The opening and closing chapters of the publication provide information on the current and historical changes made to this document, correspondingly.
