Trelleborg Provides Floatover Technology For One Of World’S Largest Oil Platforms

December 13, 2013

Trelleborg’s engineered products operation supplied its floatover mating technology to one the world’s largest oil platforms; the SHWE Project in the Bay of Bengal, Myanmar.
Working closely with the engineering, procurement, construction and installation contractor, Hyundai Heavy Industries (HHI), Trelleborg provided a number of its leg mating units (LMU), deck support units (DSU), load transfer units (LTU) and floatover fender systems, to meet requirements for the heaviest load that an LMU has ever been commissioned for. With the project’s topside weighing in at a substantial 30,000 tonnes, one of the LMUs Trelleborg delivered was designed to bear a compression load of 12,450 metric tonnes.
Following a 23 day voyage, which totalled nearly 4,000 nautical miles from HHI’s fabrication yard in Ulsan, Republic of Korea, the topside finally reached its destination at a water depth of approximately 110 meters. The barge which transported the topside was equipped with eight of Trelleborg’s DSUs. These were fixed to the deck support frame to allow horizontal movement between the deck and deck support frame during and after the mating process, when the barge separates from the topside.
Four of Trelleborg’s LMUs were used to take up the static and dynamic load of the topside structure during installation onto the pre-installed substructure. In addition, four LTUs were provided to transfer all the system loads, as well as providing substantial dampening effect to minimise any damage to the supporting structure.
