A 600 kW/cyl MAN 6L32/44CR main engine is to be installed in a new North Sea fishing purse-seiner/trawler, the first ever common rail engine to be installed in a vessel of this type in the Norwegian commercial fishing sector, according to engine builders MAN Diesel and Turbo. Graphic rendering of the Kvannøy (courtesy Hansen Dahl) A widely-used engine in merchant ships, the 32/44CR marine diesel engine was the manufacturer’s first all-electronic four-stroke engine, launched in 2006 to supplement the popular 32/40 series with a CR fuel- injected derivative.  The six-cylinder version 32/44 engine (32 cm bore/44 cm stroke) is rated at 3,600 kW and uses the latest MAN Diesel & Turbo common rail technology to enable the flexible setting of injection timing, duration and pressure for each cylinder. Thus fuel consumption and emissions may be optimised at any point on the operating profile.

Fishing trawler Vellee sank in the Little Minch channel west of Scotland’s Isle of Skye on a calm and clear night last summer apparently without being holed, leading MAIB (UK Marine Investigation Branch) investigators to conclude in their recent accident report that the loss probably resulted from a catastrophic failure of internal sea water piping or fittings – most probably the outcome of advanced electrolytic corrosion. Fishing Trawler Vellee: Photo courtesy of Skipper JimmyT Evidence of Corrosion as Probable Cause A few days before the trawler’s final voyage (from Fraserburgh north-about mainland Scotland to Kilkeel on the east coast of Ireland for better fishing in the Irish Sea) repairs to the main engine were needed, and engineers discovered that two of the eight cylinder liners of the main Kelvin TASC8 engine were badly corroded by electrolytic action; thickness reduced by as much as 85% in some places. An electrician called to investigate, thought that ... [More]
