ClassNK granted its notation indicating that the vessel is provided with the cutting edge hull monitoring system, for “DREAM CLOVER”, a 211,000-dwt bulk carrier which was built by Japan Marine United Corporation for Daiwa Kisen Co., Ltd., and to be chartered by NYK Line, says a press release published on their website.
The vessel is marked with the first DSS (Hull Monitoring) on its notation in ClassNK’s registry.
Guidelines for Hull Monitoring
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, utilizing the outcome of R&D performed by stakeholders.
Includes comprehensive requirements
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.
Functions of the system
The cutting edge hull monitoring system equipped to 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.
Vessel verification
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.
Verification of the digital twin
As a part of Japan Ship Technology Research Association’s “R&D of the highly accurate digital twin models for ship hull structures (Supported by The Nippon Foundation)”, additional sensors and measurement devices are going 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.
