Energomontaż-Północ Gdynia (EPG), a member of MARS Shipyards & Offshore, has completed construction of oil and gas loading elements for Norwegian Gina Krog field.

Submerged turret loading (STL) and riser base, made by EPG, weigh 500 tones. Riser base will be installed on the seabed and will be used to provide oil to the surface, while the turret will deliver oil directly to the floating storage and offshore unit (FPSO).

According to the company, the diameter of the structure is 11,2 m and the height is 13 m.

The structure required advanced machining in order to meet strict dimensional tolerances, EPG said.

The Gina Krog oil and gas field is located in Norwegian part of the North Sea (30 km away from the Sleipner platform) in approximately 1116 m water depth. The first production is scheduled for early 2017.

The gross recoverable reserves are estimated at 225 million barrels of oil equivalent.
