The FPSO Noble Seillean is a dynamically positioned floating oil production, storage and offloading vessel.

Etymology

The name Seillean means "honeybee" in Gaelic.

History

The vessel was designated as a single well oil production ship (SWOPS) when constructed for BP by Harland and Wolff in 1990. The vessel was designed for the Cyrus oilfield on Block 16/28 in the UK sector of the North Sea. Later she served on the Donan field. Seillean was sold by BP in 1993 to Reading & Bates.[2] As Brazilian oil company Petrobras took the decision to develop the Roncador field, a four-year charter for Seillean was signed. In 1997-1998, Seillean was upgraded and arrived in Brazil in December 1998.[3]

After acquisition of Reading & Bates by Transocean, the vessel was acquired by Frontier Drilling in 2002.[2] She was moved to Jubarte field.[4] In February 2006, the vessel started to operate in the Petrobras-operated Golfinho Field in the Espirito Santo Basin off Brazil.[5] In 2007, Seillean was moved to Pipa 2 oil field.[6]

In June 2010, FPSO Seillean was contracted for the oil collection and processing at the Macondo Prospect to deal with the Deepwater Horizon oil spill.

With the purchase of Frontier Drilling in 2010, FPSO Seillean was acquired by Noble Corporation. She was renamed Noble Seillean and her flag was changed from Panama to Liberia.[1]

Description

FPSO Seallean is a dynamically positioned monohull floating production, storage and offloading vessel. She is classed by Lloyd's Register of Shipping as a 100A1 Oil Processing Tanker. Seallean is equipped with a flare, two cargo-handling cranes, a process plant inside the hull, a completion tower, and crew accommodation. The vessel has a displacement of 79,600 tonnes, the capacity to process up to 20,000 barrels per day (3,200 m3/d), and to store up to 306,000 barrels (48,700 m3) of oil.[3] Ship's length is 249.7 metres (819 ft), breadth is 37 metres (121 ft), and depth is 20.5 metres (67 ft). She could operate at the water depth of 2,000 metres (6,600 ft). The vessel is equipped with a helideck of 29 by 27.5 metres (95 by 90 ft).[7]

Seillean is powered by a hybrid system of three Ruston gas turbine of 3.3 MW each, and three MAN diesel driven generators 4.2 MW each.[7] These are operated such that when fuel gas is available from production operations, the gas turbine generators generate electrical power. When fuel gas is unavailable, the diesel driven generators provide the power, supplemented by the gas turbine driven generators operating on diesel oil.

Seillean has the following production facilities:

  • 26,500 barrels per day (4,210 m3/d) processing plant. Maximum oil production is 25,000 barrels per day (4,000 m3/d) and maximum produced water handling capability is 15,000 barrels per day (2,400 m3/d).
  • Storage and transport facilities for 310,000 barrels (49,000 m3) of oil.
  • A 6-5/8" riser which can connect to a subsea wellhead.

The crude oil is pumped from the process plant to six cargo oil tanks. During the 1998 upgrade, an offtake reel system was installed which allows to ship discharge of cargo to a dynamically positioned shuttle tanker.
