NYK Advances Design of Subsea Cable-Laying Vessel
the development of Japan’s future high-voltage direct current (HVDC) transmission network, marking a key milestone in a national effort to strengthen offshore renewable energy infrastructure.The vessel’s design recently received General Design Approval (GDA) from classification society ClassNK, confirming that the concept meets relevant international conventions and classification rules at the detailed design level.The project is part of Japan’s broader push to build an efficient subsea power transmission system capable of transporting electricity generated by offshore wind farms
Innovative ‘Wall Climbing Robot’ for Ship Inspection Earns ClassNK Endorsement
The wall climbing robot for steel structures - developed by Mitsui O.S.K. Lines, Sumitomo Heavy Industries, and MOL Ship Management to support ship inspection and maintenance - has completed a demonstration test and earned the Nippon Kaiji Kyokai (ClassNK) Innovation Endorsement.The Innovation Endorsement is ClassNK's third-party certification program. It certifies and supports initiatives that contribute to the sustainable evolution of maritime and offshore businesses.The robot developed by Japanese partners is characterized by its high traversability not only on vertical walls but also on
Huisman to Supply Two Subsea Cranes for Toyo’s New Cable Layer
VARD 9 15 design is expected to advance capabilities for cable-laying and turbine foundation installation works in the Japanese offshore wind sector.Designed to meet the specific Toyo’s requirements and preferences of Toyo, 250 mt Hybrid Boom Crane will undergo certification according to ClassNK regulations.It represents a proven subsea crane concept that combines the high lifting height of a conventional lattice-type boom crane with the operational advantages of a Knuckle Boom Crane.The 100 mt Knuckle Boom Crane, part of Huisman's recently launched subsea crane range for offshore constructi
New Wave Data Underpins Ship Structural Integrity
;IACS researchers have determined that while Version 2 does not include any climate forecasts, IPCC projections of changes in extreme wave height are unlikely to affect the scatter diagram.Day-to-day forecasts are, however, particularly vulnerable to the “butterfly effect.” Previous work by ClassNK indicates that as atmospheric circulation has the nature of chaos, if there is an error in an initial value, the error in the predicted value will increase exponentially over time. Wave forecasts, therefore, are often limited to about 10 days.Digital solution providers, including Sofar, are giving
Furuno's Berthing Aid System Receives ClassNK's Endorsement
Japanese classification society ClassNK has granted its Innovation Endorsement for Products & Solutions to a Berthing Aid System developed by Furuno.Furuno's Berthing Aid System displays the distance and angle between the ship and the quay to assist in berthing operations.The Berthing Aid System uses LiDAR to calculate the relative distance and angle between the quay and hull, and displays superimposed images for situational awareness. The system aims to improve safety during berthing by measuring and visualizing the positional relation between the quay and ship, which was previously measured
ClassNK Offers Guidelines for ROV/AUVs
ClassNK produced "Guidelines for ROV/AUV” which summarize the performance and safety requirements for remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs).To date, ROVs and AUVs have been mainly used for oceanographic surveys and offshore oil and gas field development, but in recent years their utilization as a means for maintaining offshore wind power generation facilities and pipelines has been steadily increasing. Although the utilization of ROVs and AUVs is increasing worldwide, no international standardization of such technologies has yet been implemente
MOL Develops Engine Diagnosis Application
Japan's largest carriers of containerized and other cargo Mitsui O.S.K. Lines (MOL) announced an agreement for joint development of the next-generation engine failure sign diagnosis application, in partnership with ClassNK Consulting Service, IHI Power Systems, and Mitsui E&S Machinery.The four companies are looking to develop the application by fusing ClassNK's "CMAXS LC-A/e-GICSX"(CMAXS) and MOL's FOCUS "Fleet Optimal Control Unified System", which is intended to enhance safe operation and reduce environmental impact through advanced information and communications
Shipbuilding: Cable Layer Delivered to Japan
and provides a comfortable platform for the operational personnel and the interior design of the vessel is aesthetically appealing. The vessels material, equipment, construction, quality and performance conform to the highest internationally accepted marine industrial norms and standards. It is built to ClassNK classification society standards and meets the regulatory requirements of the Japanese Government (JG requirements).Colombo Dockyard PLC is a flag ship investment of Japan and operates in joint collaboration with Onomichi Dockyard Company Limited of Japan. The Sri Lankan Government institutions
