Joint Study by MAN and GL on LNG as a Fuel for Container Ships

MAN Diesel & Turbo together with Germanischer Lloyd have published a study analyzing the problem of the best way for container ships to meet the present and future exhaust emission regulations. The four technologies investigated in the study are: exhaust gas cleaning by scrubber, scrubber plus Waste Heat Recovery (WHR), LNG as a fuel and LNG with WHR. In the study, circumstances were considered for five sizes of container ship. The smallest is a feeder of 2,500 TEU going up to the largest of 18,000 TEU. For each ship size the speed, engine power, round trip distance and percentage of distance spent in Emission Control Areas is estimated proportionally. The study concludes that LNG offers lower emissions and given the right circumstances, less fuel cost. [More]

Specialist ship owner Anthony Veder, Netherlands, new LNG carrier ordered from Mayer Werft, Germany is due for delivery in the second quarter of 2012. A direct mechanical drive system is specified for the vessel which is believed to be the first application of its type. The new LNG carrier has a capacity of 550,000 ft3 (15,600 m3) with a LOA of 512 ft (156 m) The single shaft propulsion system comprises a Wärtsilä 50DF dual-fuel engine going through a reduction gearbox to a controllable pitch propeller. Operation on LNG all but eliminates SOx emissions and reduces the production of CO2 and NOx to levels that are sufficiently low as to be within the IMO Tier 3 NOx regulations and compliant with the requirements of the ECAs.

Diesel engine fuel switching from heavy oil to low sulfur content marine distillates as ships enter the 24-mile offshore Emission Control Area (ECA) of the California Air Resources Board has not always gone smoothly. Now comes an electronic control device, the Diesel Switch MK ll, culmination of ten years' R&D by Swedish manufacturers  JOWA Technology, a tool designed to speed up the whole process while removing the wrinkles from a procedure that demands meticulous attention by ships' engineers. Earlier in the week the company, whose technology has been given a stamp of approval by classification society Germanischer Lloyd, reported orders for installation in ten ships of Norway’s Jo Tanker fleet, as well as in its newbuildings. Tanker Jo Sycamore: Photo credit JOWA Technology Over the past year USCG and other regulators (those in the European Union ECA too) flagged reports of failed main engine start-up, stalling, variable engine speeds at low loads as well as insta...

Japan’s shipbuilder Kawasaki Heavy Industries (KHI) is showing a new design of LNG fueled container ship. The design and development are at an advanced stage and Classification Society DNV has granted Approval in Principle.The container ship, of 9,000 TEU capacity, has an LOA of 1,010 ft (308 m), beam of 157 ft (48 m) and draft of 47 ft (14.5 m). The ship will be propelled by a single, electronically controlled, slow speed, two stroke, dual fuel main engine and will be offered with EGR which satisfies IMO Tier3 requirements. It is the first time that Type B, LNG storage tanks will be used on such a large container ship. Type B tanks continuously produce boil-off evaporating LNG and must be used up for propulsion or powering auxiliaries in port, for example supplying power for reefer containers. [More]
