The following is the text of a news release from ClassNK:
(TOKYO) — Classification society ClassNK has released draft amendments to its rules and guidance for container carriers. The amendments were approved by the ClassNK Technical Committee in Tokyo on Nov. 19.
The ClassNK Technical Committee is made up of representatives from the shipping and shipbuilding industries as well as scholars and experts to discuss matters relating to the establishment and revision of technical rules and guidance.
In response to a large containership casualty in June 2013, ClassNK established the Investigative Panel on Large Container Ship Safety, which comprised of shipbuilders, shipping companies and people with relevant knowledge and experience, to investigate the possibility of casualty occurrence and the structural safety of large container carriers. The results from the investigation and ClassNK’s action plan were released in the Investigation Report on Structural Safety of Large Container Ships in September 2014.
On the other hand, Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Committee on Large Container Ship Safety released recommendations of requirements for large containerships in its final report in March 2015.
Furthermore, the International Association of Classification Societies (IACS) adopted the new Longitudinal Strength Standard for Container Ships (Unified Requirement S11A) and Functional Requirements on Load Cases for Strength Assessment of Container Ships by Finite Element Analysis (Unified Requirement S34).
Based on the IACS UR S11A and S34, and the reports released by ClassNK and Japan’s MLIT, ClassNK drafted amendments to its relevant rules and guidance. These amendments were then submitted to and approved by the ClassNK Technical Committee.
The development and implementation of more comprehensive rules demonstrates ClassNK’s commitment to building even safer ships. The amendments will come into effect after receiving approval from ClassNK’s board of directors. The rules are scheduled to apply to containerships contracted for construction on or after April 1, 2016, three months before the application of the IACS UR S11A and S34.
The draft amendments are available on the ClassNK website for "My Page" users at the Rule Amendments for Technical Rules section. Registration for ClassNK’s "My Page" service is easy and free. Go to ClassNK’s website at www.classnk.com and click on "My Page Login."
