The Kittiwake platform is located 160km East of Aberdeen, in Licence block 21/18. The platform coordinates are; latitude 57°28ˈ6"N, longitude 00°30ˈ43"E. The platform stands in a water depth of 85m.
The Kittiwake platform was installed in 1990 and is a fixed steel platform on the Kittiwake field with other fields being developed as subsea satellite tie‐backs to the Kittiwake platform. The subsea satellites consist of; Goosander (block 21/12), Grouse (block 21/19), Gadwall (block 21/19) and Mallard (block 21/19). These fields are collectively known as the Greater Kittiwake Area. Petrofac are the current duty‐holders, operating the installation on behalf of Enquest. Enquest and Dana Petroleum are 50/50 partners in the Greater Kittiwake Area.
The living quarters has a maximum POB of 77, and normal POB is around 70. The platform no longer has drilling facilities which were decommissioned in 2009.
Fluids from the Kittiwake reservoir are recovered through platform drilled wells and the Goosander, Grouse, Gadwall and Mallard reservoirs are recovered through subsea tiebacks. Originally designed for tanker export, the produced oil flows through a 4 stage crude stabilisation system. Mallard and Gadwall have their own dedicated first stage separator in parallel, before the oil is co‐mingled upstream of the second stage separator.
Stabilised oil is metered then exported using the oil export pumps to the Forties Pipeline System via a 10" oil export line to Forties Unity. Produced gas is compressed and used for fuel and gas lift. The surplus gas is exported via a 4" export line to the near‐by SEGAL gas pipeline. Produced water is cleaned and discharged overboard to the sea.
Oil evacuation system
Oil is exported via a 33km, 10" pipeline (installed in 2007) from the platform to the BP operated Forties Unity platform. Oil used to be exported onto a shuttle tanker using a single point mooring system, which was removed in 2008.
