Ottó N. Þorláksson back to sea next month
It is hoped that fresher trawler Ottó N Thorláksson will be back at sea by mid-February. A main bearing in the ship’s main engine failed at the end of November last year but fortunately the fault was located before sailing.
As had been feared when the bearing failed, there was also damage to the crankshaft and other engine parts. Stálsmiðjan – Framtak was contracted to handle the repair and the extent of the damage was not apparent until the engine had been stripped down.
According to HB Grandi’s marine superintendent Gísli Jónmundsson, there has been good progress on the engine repair.‘We never expected the repair job to be complete before we were into February. The main engine had recently been overhauled, before the bearing failure, so cylinder collars, bearings and other components had already been replaced,’ he said, commenting that there was serious damage to the engine in this instance. It was stripped down and reassembled with a replacement base, crankshaft and block.
‘We sourced a second-hand engine from Holland and used the block, crankshaft and base from that and exchanged parts as needed. This is a 2005 engine block and other components dating from 2002. So these are practically new compared to Ottó N Thorláksson’s main engine that was built in 1978 and has been in use since 1981. Assuming everything works out, we’ll have a much better main engine as the old one was showing its age,’ Gísli Jónmundsson said.
