The good track record of Colombo especially for speedy turnaround and quality workmanship, coupled with MT.

The work package to be carried out during this call consisted of: Routine drydocking repairs, hull blasting and painting; introduce additional strengthening and modifying deck longitudinal frames to avoid generating cracks (high tensile steel plates were used for this modification); introducing new frequency converters for engine room fans and sea water pumps in order to improve fuel consumption; fabrication and installation of sludge tank of 2.5 cm with all pipes, fittings and attachments and installation; strengthening of main mast by introducing new wire stays; introducing additional stiffeners to radar mast and improve the strength and rigidity; modification of various pipe lines and overhauling of plate and tube type coolers, valves and electrical motors.
