this material. T e company operates shipyards in Karisk- rona, Malmo and Musko. Kockums said it would build Fintry CarboCat vessels,
which are up to 30% lighter than aluminium and far stronger than either aluminium or steel. Fuel savings are expected to reach more than 20%. T e carbon fi bre material is non-corrosive and the sandwich formulation possesses a low maintenance cost with an extremely high safety factor. In addition to the savings in fuel and mainte- nance costs, these lighter vessels will require smaller engines to achieve performance equivalent to similar sized builds in aluminium, thus enhancing their environ- mental footprint.
Classifi cation New sloshing guide
from LR Lloyd’s Register has published a new guidance document for the design of membrane-technology liquid natural gas containment systems. T e document is aimed at improving design procedures
with respect to sloshing forces, and is the result of a long programme of research and development, including extensive consultation with industry, and an investment of over £700,000. T e document has been used as part of the appraisal process for the approval of the largest LNG carrier built to date – the Q-Max type ships, of which Lloyd’s Register is the lead class. ‘Sloshing Assessment Guidance Document for
Membrane Tank LNG Operations’ provides guidance and recommendations on the assessment of sloshing in membrane LNG tanks. It provides design teams with an overview of suitable procedures for assessing the strength of Gaztransport and Technigaz NO96, Mark III cargo containment systems (CCS) and also new containment systems. Nigel White, technical manager, hydrodynamics, with
Lloyd’s Register’s Marine Product Development team, said: “LNG sloshing is a very complex issue as there are many aspects that are diffi cult to address explicitly by calculation or testing. Consequently, the assessment of the cargo containment system of membrane LNG ships for

sloshing loads is very complicated and there is no single defi nitive assessment procedure that may be applied. T e new document is written as guidance and it provides best engineering practice on the assessment of the CCS and the supporting hull structure. T e guidance mainly applies to membrane tank LNG
ships with a barred fi ll range typical of the vast majority of membrane tank LNG ships in current operation. Recently there have been several incidents involv-
ing damage to LNG membrane tanks and the approach adopted in the document provides guidance on the processes necessary to ensure that these incidents will not recur. Hence, as part of the design process, the designer should undertake a risk assessment and a hazard review to determine all possible failure modes. Having done this, it is then possible to set suitable design appraisal methods and acceptance criteria to show that these potential hazards are clearly controlled.
Research and development MOL Technology to
move Mitsui O.S.K. Lines, Ltd has announced plans to move
its MOL Technology Research Centre from its current site in Nishikojiya, Ota Ward, Tokyo, to Aso Ward in Kawasaki, Kanagawa Prefecture. The MOL Technology Research Centre has taken
a proactive approach to analysing vessel fuel oils and lubricants, developing a fuel oil pre-treatment device, research and development on CO2
reduction, and other
R&D eff orts to improve storage and transport technolo- gies such as advanced reefer containers. MOL decided to move the centre to Micom City at
Kuriki in Kawasaki’s Aso Ward because of the age of the current buildings and changes in the surrounding environment. T e new centre will be an environmentally-friendly
research facility using energy-saving technologies such as solar energy, natural lighting, and an ice thermal storage system, using electricity to make ice at night, when demand for power is low, and then melting the ice for air conditioning.
