MOL bulk carrier uses special steel that absorbs impact
Mitsui OSK Lines has a new bulk carrier — the first ship to feature a new type of highly ductile steel plate that will increase safety to cargo and the environment.
The steel, known as NSafe-Hull, is designed to absorb side impact to the hull three times more effectively than conventional steel plate, which is claimed to reduce the risk of cracks in the hull and significantly increase vessel safety.
The metal was developed in Japan by Nippon Steel and Sumitomo Metal Corporation. NSSMC says it developed NSafe-Hull through "designing chemical composition and micro-structural control in crystalline scale."
The new bulk carrier was built by Imabari Shipbuilding, and launched on August 2 of this year.
The 299.4-meter-long, 206,600-dwt ship used a total of about 3,000 tons of NSafe-Hull, which was used for sections such as the side plates of cargo holds and fuel tanks. According to MOL, these are areas where hull strength is especially critical, improved puncture resistance helping to prevent flooding, protect the cargo, and reduce risk of environmental damage from oil leakage.
NSSMC describes NSafe-Hull as "a highly ductile steel plate for shipbuilding with improved collision safety". It was jointly developed by NSSMC, Imabari Shipbuilding and Japan's National Maritime Research Institute (NMRI).
