Overhaul of the crane on a vessel


We have overhauled the crane onboard a vessel. Due to this vessel already had another job offshore, our challenge was to engineer and produce all (prefab) components while the vessel was still at the harbor and install the whole system while sailing from Cape Verdi to Stavanger under the most extreme weather conditions.

Key was excellent preparation by calculating, engineering and prefabricating all components ‘plug-and-play’ to excluding installation challenged while sailing.

This vessel is one of the largest pipelay vessels in the world and has set new standards in the pipelay industry. The vessel has been operational since 1998 and has since steadily improved her performance. Based on the same principles as their other pipelay vessl her long length and ship-shape ensures excellent workability, and a pipe carrying capacity of 22,000t makes her less dependent on offshore pipe supply in hostile areas.
Precise maneuvering on full dynamic positioning allows the vessel to work safely in congested areas.

To this vessel we have supplied and installed a total of 340 hoses with a length of 10mtr with sizes from ¼” till ½”. We have well trained personnel according OPITO and NOGEPA (Bosiet). Hydrotek (part of AVT) has manufactured all Offshore approved hoses, AVT HydrauliQ has installed them offshore.
