A&P Tyne completes CSO Wellservicer mid-life refitYard News // June 6, 2003
The vessel arrived at the yard in November last year and work was completed in late April.
The work on the CSO Wellservicer included a complete refurbishment of the entire vessel's deck and engine-room equipment. This included the re-engining of the diesel-electric propulsion system; removing the original six Hedemora diesels generating sets and replacing them with six new Wartsila 12V200 diesel engines connected to ABB generators.
The propulsion system is divided into two separate engine rooms, with three diesel-generating sets located in each, providing power for three Kamewa azimuthing thrusters (port, centre and starboard), and two bow thrusters. All the thrusters were disconnected from the vessel and taken to the yard's extensive machine shop facilities for overhaul.
Apart from the re-engining operation and work on the thrusters, the refurbishment specification also included: renewal of deck plating and stiffeners; a complete refurbishment of the accommodation; dismantling of the single-pedestal, twin deck crane, refurbishment and re-installation; overhaul of various engine room equipment; complete dry-docking, blasting and painting.
