    Maintenance programme on Flintstone completed

    Yard News // April 19, 2016

    The fallpipe vessel Flintstone has departed Damen Shiprepair Amsterdam following a six-week programme of maintenance and repairs together with her first Special Survey. Owned and operated by the Tideway group of companies, a division of the Belgian dredging, environmental and marine engineering group DEME, the 155m, 20,000 tonne DP2 Flintstone is equipped with an active heave-compensated ROV with survey equipment and a 200kW mass flow excavation tool for the removal of seabed materials.

    Flintstone underwent a comprehensive programme of maintenance, surveys and testing in the run-up to her Special Survey, spending a total of 28 days in drydock at Damen Shiprepair Amsterdam. Of the many activities that took place, the most complex with regard to the vessel itself was the refurbishment of the moonpool doors. These were lowered and supported on the floor of the drydock in order to undergo extensive maintenance, including the replacement of the main bearings. The unexpected and large scale of the machining work required made this 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.

    While at the yard 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.
