CLASSNK GRANTS FIRST HULL MONITORING NOTATION TO LARGE BULKER

CLASSNK GRANTS FIRST HULL MONITORING NOTATION TO LARGE BULKER

Wednesday, August 4, 2021 

ClassNK has granted its notation indicating that the vessel is provided with an advanced hull monitoring system, for 'Dream Clover', a 211,000 dwt bulk carrier which was built by Japan Marine United Corporation for Daiwa Kisen, and delivered in July 2021, to be chartered by NYK Line.

The vessel is marked with the first DSS (Hull Monitoring) on its notation in ClassNK’s registry. In the light of the rapid technological evolutions of hull monitoring systems and the industry’s growing needs, ClassNK released Guidelines for Hull Monitoring in June 2021, based on a study performed by stakeholders. The guidelines include the comprehensive requirements to be met to achieve functions contributing to improving the safety of the hull structure and the class notation indicating that the ship is provided with specific functions.

The hull monitoring system onboard Dream Clover has functions such as assistance for maintaining and managing the ship based on the fatigue strength evaluation and assistance for the captain’s operation in the rough condition. ClassNK has verified the vessel according to the related guidelines and issued the class certificate with DSS(HM(F+LS,O)) notation for hull monitoring, the first in ClassNK’s registry, and DSS(EE) for energy efficiency analysis function.

As a part of the Japan Ship Technology Research Association’s study of highly accurate digital twin models for ship hull structures, supported by the Nippon Foundation, additional sensors and measurement devices will be added to the monitoring system of the vessel, and a verification of the digital twin model for hull structures on the actual ship is expected to be conducted.
