Mammoet loads out 7,400 tonne platform

A 7,400 tonne oil platform was loaded out by Mammoet Russia before its transport to Lukoil’s Vladimir Filanovsky field in the Caspian Sea. It was the the offshore, ice-resistant, stationary platform LSP-2 which Mammoet loaded out onto a barge using an hydraulic push up system.
The Filanovsky field is the largest oil discovery in Russia in 25 years. It is in the northern part of the Caspian Sea, 220 km from Astrakhan. Reserves are anticipated to be 129 million tonnes of oil and 30 billion cubic metres of gas. Production of the new platform, which is for Phase two of the field’s development, will equal 6 million tonnes a year.
In 2014, working for Lukoil on the same field, Mammoet Russia worked on the construction and load-out of a central processing platform (CPP) weighing nearly 10,000 tonnes. The latest contract was won on the back of this earlier. Mammoet Russia was contracted for the weighing, jacking and load-out of the LSP-2 platform. For weighing and jacking Mammoet used its JS2400 push-up system.
It means large and heavy structures can be built on the ground and raised to the correct height for load out. A load-out frame was inserted during jack up to provide sufficient height for installation at sea. Using this system removes the need to work at height, significantly increases safety and reduces the time needed for the operation. Weighing, jack up and load out took less than 40 days, Mammoet said.
