The unexpected and large scale of the machining work required made the 'Flintstone' repair job challenging to carry out

The Fallpipe vessel ‘Flintstone’ has departed from Damen Shiprepair Amsterdam following a six-week programme of maintenance and repair, along with the completion of its first special survey.

While in the yard, Flintstone underwent a comprehensive programme of maintenance, surveys and testing in the run-up to its special survey, spending a total of 28 days in drydock.

Arnold Bregman, project manager, said: “This was a very challenging project given the extent of additional works that became apparent as we progressed. However, Damen Shiprepair Amsterdam was the ideal location for this with all the necessary facilities available on site.”

The most complex job that had to be completed while the vessel was in the yard was the refurbishment of the moon pool doors. These had to undergo extensive maintenance, including the replacement of the main bearings.

It was the unexpected and large scale machining work required which made it a very challenging job to carry out within the original time allowed.

Other activities included the overhaul of all the thrusters together with the forward anchor winches and a wide range of other tasks relating to the water lines, fall pipes, ROV transport and storage, and other equipment.

At the same time, the Huisman crane and tower were overhauled by the manufacturer. The yard provided full support including machining and supplying various components, and provided a berth for the extra time required to complete the project.

The 155m, 20,000 tonne DP2 Flintstone is owned and operated by the Tideway group of companies, a division of the Belgian dredging, environmental and marine engineering group DEME.
