Recently, ClassNK has received several reports for incidents that sea water leakage was detected from distance piece attached to hull on SOx scrubber discharge water line. The design and possible problems are similar for all vessel with scrubber installations.
ClassNK, Japan Marine United (JMU), and NAPA have carried out a joint feasibility study on 3D model based plan approval using 3D CAD models as part of their technical investigation project.
In line with an increased shift to environmentally-friendly solutions as a pathway to decarbonization, ClassNK announced it is joining the International Windship Association (IWSA), which is working to promote wind as a viable propulsion option for commercial vessels.
ClassNK published guidelines concerning autonomous ships and operations aiming to improving safety by preventing human error and improving working conditions by reducing the work load on crew members, and demonstration experiments are being carried out on a global scale.
ClassNK, the leading classification society, certified the Cyber Security Management System (CSMS) of NYK LNG Shipmanagement Ltd. (LNGSM), the NYK Group subsidiary, and its managed LNG carrier Pacific Mimosa; becoming the first CSMS certified by the Society.
Classification Society ClassNK has concluded a joint research agreement for developing advanced condition-based maintenance (CBM); a new maintenance and management system to be used for the machineries of autonomous ships, as well as to further establish a new classification survey scheme based on CBM.
Classification Society ClassNK has released its “Guidelines for the Inventory of Hazardous Materials (Ver.4.00), the development of which will be required for ships over 500GT after the Hong Kong Convention enters into force.
ClassNK announced its participation in the Getting to Zero Coalition highlighting its aspiration on achieving a greener and more sustainable future for the shipping industry. ClassNK supports that its participation in the initiative will boost and strengthen its GHG-emission targets.
MOL and Oshima Shipbuilding have jointly obtained ‘Approval In Principle (AIP)’ from ClassNK for the design of a hard sail system. The system converts wind energy to propulsive force with telescopic hard sail. As MOL said, the system is crucial for the ‘Wind Challenger Project’, which MOL and Oshima Shipbuilding are leading.
In order to comply with the new sulphur limit for fuel oil used on board ships, starting on 1 January 2020, fuel oils with a sulphur content of 0.50% or less will be supplied worldwide for bunkering. For this reason, ClassNK published a booklet with precautions regarding the change-over to compliant fuel oils.
