Classification society ClassNK has granted its first DSS (Hull Monitoring) notation to the 211,000dwt bulk carrier Dream Clover – built by Japan Marine United Corporation for Daiwa Kisen Co and to be chartered by NYK Line – indicating that the vessel is provided with a cutting-edge hull monitoring system.

In the light of the rapid technological evolution of hull monitoring systems and the industry’s growing need for energy efficiency, ClassNK released Guidelines for Hull Monitoring in June 2021, utilizing the outcome of R&D performed by stakeholders.

The hull monitoring system installed on 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 ongoing Japan Ship Technology Research Association’s R&D work, additional sensors and measurement devices are going to be added to the monitoring system of the vessel, and verification of the hull structures on the actual ship is expected to be conducted using its digital twin.
