German oil company Deutsche Oel & Gas AG has installed a production platform over its Kitchen Lights field in the Cook Inlet, Alaska.
The installation procedure was conducted by SAL Heavy Lift’s MV Svenja heavy lift and installation vessel. First gas from the platform is expected to flow starting the end of 2015. The production platform will be connected by a 16-mile long subsea pipeline to the onshore processing facility located in Nikiski, Alaska.
In a release announcing the completion of the installation, Sal Heavy Lift, based in Germany, provided a piece of information on the platform installation procedure.
According to the company, the new development platform consists of three main parts which had to be assembled. First the King Pole, which works as the central pole, had to be driven into the seabed by a large hydro hammer. In the next step, the monopod was moved to the MV Svenja by a barge and then lifted onto her deck for further preparations.
Subsequently the two 1000 tons cranes of the MV Svenja lifted the monopod off the vessel again and lowered it accurately down to the seabed.
Finally the topside, measuring 33 x 30 x 27 meters, was placed onto the monopod with a 700 tons single hook lift.
“The topside installation was very tight and tide dependent. Only during high tide the installation window was open for about four hours” , said Corporate Director – Engineering & Ship Management Rüdiger Bauer .
Following the completion of the platform installation in the Cook Inlet, SAL Heavy Lift’s MV Svenja has now returned to Singapore for demobilisation.
