The installation of modules for the Åsgard field's subsea gas compression system has begun, Norwegian oil major Statoil reported Tuesday.
The modules, of which there will eventually be 22 in place, are being installed at a depth of 985 feet. They make up a system that comprises two identical compressor trains weighing 1,500 tons each that will help Åsgard. which is located on the Halten Bank in the Norwegian Sea, produce an extra 282 million barrels.
The installation work is being carried out by the North Sea Giant vessel, which was reconfigured specifically for this work. The smallest modules are being installed using the vessels "moonpool", which is a large opening in the bottom of the hull through which the modules are lowered. The ship's crane system is installing the other modules and has been modified to incorporate a special handling system that is designed to carry a load of up to 420 tons and operate in waves of up to 30 feet.
"I am very pleased that we have now commenced the installation work and that preparations for start-up and operation are now underway," Snorre Grande, senior vice president for the Åsgard subsea gas compression in field development, said.
"The ship fitted with the new crane system will also be a good tool for us once the system becomes operational."
