Great Ship: White Rose

Builder Samsung Heavy Industries Co., Ltd.

Owner Husky Oil Operation

Type FPSO

For many years now, contracts for ships and floating units to operate in an offshore environment have been much-prized value-added goals at Samsung. These include not only shuttle but drill ships, floating storage and offloading units (FSOs), with their derivative production types (FPSOs), crane ships, and various types of floating and fixed platforms. Some of the more interesting ships that have been created here have included a trio of deepwater drill ships for Reading & Bates capable of working in water depths down to 3000m, the 312,500 dwt FPSO Bonga for operating off Nigeria, and the Saibos FDS, a pipelayer/crane vessel with a jib capacity of 600tonnes. However, today, one of the most interesting ship-shape designs currently on order at Samsung is a very special FPSO planned to operate in the White Rose field off the eastern coast of Newfoundland, Canada. This is a particularly hazardous and inhospitable area of the world, known both for storms, but more importantly it is also in an iceberg zone. The most recent new production unit to be stationed there was the Terra Nova FPSO, designed by Halliburton Brown & Root, and completed by Daewoo in 1999, and the operator of the new ship, Husky Oil, was seeking a somewhat similar concept, which was based in 'virtual drill-ship' lines using five azimuthing thrusters to maintain position. However, Samsung's design team proposed a different solution altogether, which it claims is more cost-effective. This is extrapolated from a successful shuttle tanker hull conceived by the yard for several Norwegian owners, including Ugland, and employing twin conventional CP propellers, allied to a submerged turret loading arrangement. Lengthy discussions took place with the owner which was prepared to pay extra for good safety features, while the hull itself was model tested at the Oceanic Consulting basin in St John's, Newfoundland.

Including slop tanks of 5800 cu. m., the total storage capacity will be 148,000 cu. m., and the bottoms of these tanks, along with the water ballast tanks and external shell will be protected by sacrificial anodes with a 10-year lifespan. For offloading processed oil to a shuttle tanker over a stern line, three 4,000 cu. m./hr. cargo pumps will be installed.

One of the most important requirements of a floating unit in this part of the world is an ability to move off-station as fast as possible in the event of any iceberg threat. If this becomes necessary, the submerged turret mooring system will be disconnected, together with the associated oil loading lines, and the twin 10,600 bhp (MCR) medium-speed diesel engines (burning diesel oil) will give the ship a service speed of 12 knots (at 90% MCR, including 15% power margin and a design draft of 18 m). For normal ship's services, electrical power will be provided by a pair of 2,250 kW diesel-alternators.
