ClassNK has completed the EEDI appraisal of Harvest Frost, the world’s first post-panamax bulk carrier fitted with the Mitsubishi Air Lubrication System (MALS). The Harvest Frost was constructed by Oshima Shipbuilding Co., Ltd. for ADM Harvest Shipping in accordance to ClassNK rules and guidance. Developed by Mitsubishi Heavy Industries with support of ClassNK’s Joint R&D for Industry Program, MALS uses specialized blowers to create a layer of bubbles that flow along the bottom of a hull to improve fuel efficiency by reducing frictional resistance. While EEDI is calculated and evaluated primarily based on hull form, ship speed, and engine efficiency, the IMO has also established guidelines for including the effect of innovative new technologies, such as MALS, in the verification and calculation of a vessel’s EEDI. The appraisal and certification of the EEDI of the MALS-equipped Harvest Frost is understood to be the first time that the effect such an innovative technology has been evaluated part of a vessel’s EEDI. ClassNK has supported the development of EEDI regulations throughout the deliberation and enforcement stages at the IMO. ClassNK carried out the very first EEDI evaluations as part of the deliberation process at the IMO, and has carried out EEDI certifications for ...

The first of four MSC Cruises ships to undergo the Renaissance Programme of enhancements was physically extended by 24 metres. The engineering took place at the Fincantieri shipyard, in Palermo, Sicily, and saw the 14,000 tonnes separated bow of MSC Armonia slowly advanced 30 metres away from her stern on rails to allow a new 2,200 tonnes prebuilt midship section to be inserted. The procedure marked a key milestone in the €200 million Renaissance Programme, which will enlarge and enhance MSC Armonia, MSC Sinfonia, MSC Opera and MSC Lirica, giving them all an array of new improvements and amenities. Much careful preparation was required ahead of today's separation to ensure the ship would be absolutely ready. Steel-cutting operations started on 2 September when Fincantieri's world-class engineers marked the cutting line to enable accurate grit blasting of the area. On 3 September the ship's electrical systems were deactivated. The cutting operations finished on 8 September, ahead of the event on 10 September. After the Renaissance Programme, MSC Armonia's environmental impact will be significantly reduced. She will receive a new hull treatment to minimize drag and lower water resistance, considerably reducing fuel consumption. In addition, LED technology in all public spaces on ...

Mitsui Engineering & Shipbuilding and 100% owned subsidiary MES Technoservice have received an order from Taiwan ship owner for fuel-efficiency modifications to the main engine (Mitsui-MAN B&W 12K98MC/M6) of three large type container vessels. In recent years the rising costs of fuel oil together with the need to reduce the environmental impact of shipping vessels have sharply increased the practice of slow steaming especially for large container vessels whose annual fuel oil costs can run into the billions of Yen. The modifications to be carried out, referred to as "Derating", involves reducing the MCO output by modifying the main engine and turbocharger. The modification will increase the cylinder P.max as well as the mean effective pressure thereby increasing combustion efficiency. This results in a significant reduction in fuel consumption, even greater than the method of turbo-charger cut out which has been applied to several large type container vessels in recent years. Depending on the vessel operation patterns, the expected payback period for the modification work is one-two year. The above modification work is to be carried out later this year.
