Maritime
15.4% of the world fleet to class (approx. 5,400 vessels)
19% of ships ordered in 2007
70% of maritime fuel testing market
Authorised by 130 national maritime authorities
Continuous high performance in Port State Control worldwide
DNV is a world leading classification society

Role of Classification Societies
Contribute to the development and implementation of technical standards for the protection of life, property and the environment.
Classification societies establish and apply technical requirements for the design, construction and survey of ships.
Classification rules are developed to contribute to - structural strength and integrity of essential parts of the ship’s hull - reliability and the function of the propulsion and steering systems, - reliability and the function of the power and auxiliary systems.
Classification societies also act as Recognised Organisations for Flag States, verifying the same vessel’s compliance with international and/or national statutory regulations.
© Det Norske Veritas AS. All rights reserved. Slide 731 October 2008
A classification society does not - design, - build, - own, - operate, - manage, - maintain, - repair, - finance, - insure or - charter ships.
Proper and effective construction depends upon the designer and shipbuilder doing their jobs properly.
Safe operation and maintenance of a ship for its intended service depends principally upon the shipowner, the shipowner’s representatives and the crew who operate, manage and maintain the ship on a day to day basis.
Role of Classification Societies
© Det Norske Veritas AS. All rights reserved. Slide 831 October 2008
Classification Societies set quality standards for hull, machinery and equipment and verify that ships are built and maintained according to these standards.
Classification Societies, when delegated by authorities, verify that ships are designed, built, operated and maintained according to international and national maritime safety conventions.
The Class Concept
© Det Norske Veritas AS. All rights reserved. Slide 931 October 2008
Note, classification societies are not guarantors of safety of life or property at sea or the seaworthiness of a vessel because the classification society has no control over how a vessel is operated and maintained in between the periodic surveys.
Class Scope

Class Scope
Often seen that Certificate of Class discharges duty holders obligation for safety - incorrect.
Compliance with class and statutory requirements is considered as a minimum level of safety.
Do not cover every type of risk on every type of vessel for every situation.

Fire Safety
Additional notations, focus on cost effective requirements for early detection and reduction in consequences of fire.

Nautical Safety
Voluntary notations focusing on the total bridge system
- Design of workplace- Working environment- Equipment performance and
reliabilty- Man/machine interface- Qualifications- Operating procedures.- Range of instrumentation,
Statistical evaluation of the use of the notations shows that there is a significance difference in the frequency of nautical accidents between vessels with and without these notations, by about ½.

There is always room for improvement in the way rules and regulations are developed and framed.
Safety related IMO topics on the agenda 2007-2020:- Goal based standards – outcome?- Prevention of accidents involving lifeboats- Review of the STCW Convention and the STCW Code - Comprehensive
review- Review of Principles of safe manning levels- Recovery systems for all types of ships for the rescue of persons at sea by
2012
