ClassNK grants first DSS (Hull Monitoring) notation to bulk carrier

ClassNK has granted its first DSS (Hull Monitoring) notation for a 211,000 DWT bulk carrier Dream Clover. 

The vessel was built by Japan Marine United Corporation for Daiwa Kisen and to be chartered by NYK Line. The vessel is due for delivery on 28 July, 2021.

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, utilising the outcome of R&D 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 equipped to Dream Clover includes assistance for maintaining and managing the ship based on the fatigue strength evaluation and assistance for the captain’s operation in  rough conditions. 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 Japan Ship Technology Research Association’s ‘R&D of the highly accurate digital twin models for ship hull structures’, additional sensors and measurement devices are to be installed to the monitoring system of the vessel, and the verification of the digital twin for hull structures on the actual ship is expected to be conducted.
