great ships of 2003 Name 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 environ- ment 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 operat- ing off Nigeria, and the Saibos FDS, a pipelayer/crane vessel with a jib capacity of 6()0tonnes. However, today, one of the most inter- esting ship-shape designs currently on order at Samsung is a very special FPSO planned to oper- ate in the White Rose field off the eastern coast of Newfoundland, Canada. This is a particularly haz- ardous 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 opera- tor 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 solu- tion altogether, which it claims is more cost-effec- tive. 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 bal- last 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 dis- connected, 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. Smart Pneumatic Level Sensor with Generic 4-20mA Output The Bubbler is an electro-pneumatic level trans- mitter that allows remote level measurement using a 4-20mA analog output. The lack of air pressure poses no operational problems, due to an auto- matic one-way valve which closes as soon as the pressure drops below 1 bar, this prevents back flow in the bubbling line towards the transmitter. Over pressure is also protected against by an automatic one-way valve. • It's the size of a grapefruit • Explosion proof housing • Accuracy .3% full scale • Automatic over-pressure valve • Automatic stop valve for air failure • Automatic cleaning of bubbling line • Connection for pressurized tanks • 2 pair 24 VDC and 4-20mA cable • Top or side mount Many Options White Rose Field FPSO Main Particulars Flag Canada Length, o.a. 890.7 ft.
