Engines Rebuild Gives New Life to 'Goosander'
Diesel engine specialists Bartech Marine Engineering has recently completed an overhaul of the main engine and gearbox plus three auxiliary engines and all associated parts for the MV Goosander, an ex-Admiralty Duck Class vessel now owned by Underwater Technology and operated from Lowestoft UK.
The Paxman 16RPHX MK 5 main engine had suffered major damage to the main entablature and the crankshaft, requiring the entire unit and gearbox be removed from the vessel. Partial dismantling reduced weight and increased accessibility to facilitate this process, which also required part of the vessel's superstructure, including the funnel, to be removed.
Wherever possible, parts were transferred to Bartech's new premises in Colchester UK, which include dust-free facilities, for thorough overhaul and testing.
Underwater Technology was provided with spares from Bartech's stock for the main engine rebuild.
While this work was underway, Bartech engineers were busy dismantling the auxiliary engines, fuel pumps/governors and sea water pumps. Again, all items possible were returned to the Colchester works for overhaul.
After overhaul the main engine and gearbox were reassembled on board the vessel due to weight considerations and limited accessibility.
Meanwhile, the three Paxman 6RPHX auxiliary engines were being overhauled in the same manner as the main engine.
A system of checking and logging measurements on components as necessary was established and maintained throughout this work, which included further inspection by a Lloyds Surveyor.
Underwater Technology then requested Bartech's assistance with the main engine's outdated control system, which was modified to enable MV Goosander to operate efficiently and reliably with modern controls. Neither the main engine or auxiliaries were alarmed and Bartech provided a system which could be operated without the need to enter the engine room.
Upon completion of works, basin trials were completed before the vessel was piloted out of Lowestoft for successful full sea trials which were witnessed by Lloyds, the insurers and the ship's owners.
