Offshore Sakhalin Island, Russia

ALE was approached to assist with the installation of a 21,800te floatover topside deck on the LUN-A Platform – Russia’s first offshore gas platform in the Lunskoye Field. The project set a new record as the industry’s heaviest floatover deck installation.

ALE was contracted to engineer, design and perform the barge ballasting for both the load-out and offshore floatover installation. ALE used computer modelling to design a pumping system capable of delivering sufficiently high flow rates, and fabricated non-standard pipework as required. The purpose-built barge transported the topside1,500 nautical miles to the offshore installation site, where ALE also performed all the engineering associated with mating, including ballast and mooring calculations.
