Gibdock completes quick succession double repair

“Close co-operation between the client and ourselves ensured this project went smoothly and was completed on time, to a high quality and to the owner’s satisfaction,” said Filip Tsankov, ship repair manager, Gibdock.

“This was a big project that covered almost every area of the ship and its key machinery items, and as a result required careful planning to ensure there were no conflicts between the different elements of the work scope as they were being carried out simultaneously.”

Ro-ro and container

Returning customer Compagnie Maritime Nantaise (CMN) chose Gibdock’s facilities to carry an extensive package of work on its 12,026 dwt, 160m ro-ro container vessel, MN Calao, which spent 18 days in the yard, taking in its five-year classification survey.

For MN Calao, Gibdock was tasked with carrying out an extensive and complex paint job, covering the underwater hull and the superstructure, including the funnel and mast areas, to return the vessel to ‘as new’ condition.

In addition, its two MAN B&W 7-cylinder main engines were overhauled, and the boilers cleaned, as part of a major maintenance programme that included work to the ballast water treatment plant.

During the vessel’s stay in the yard a thorough inspection of the rudder blades and steering gear was carried out and the tailshaft removed to enable new stern tube seals to be installed.

Another recent visitor to the yard was the 148m, 1,080 teu capacity container vessel Ops Hamburg, which spent around 20 days in the yard before leaving in early March.

The biggest single job involved the removal of the ship’s MAN B&W 7L 58/64 main engine for overhaul in the workshop.

Gibdock also carried out hull surface treatment, blasting and coating work and withdrew the vessel’s tailshaft, liner and rudder for inspection, which revealed the need for an unexpected amount of additional work.

In addition, the ship’s electrical motors were overhauled, stern tube seals renewed, and maintenance carried out to sea valves, among other standard drydocking work items.
