COMPLEX TERRA NOVA PROJECT NEARS COMPLETION
-Halliburton units contribute to successful execution of floating production, storage and offloading facility with subsea wells and gathering system to be installed in the Terra Nova oilfield.-
ST. JOHN'S, NEWFOUNDLAND, Canada - Using advanced technology, Halliburton Company (NYSE: HAL) units are part of an alliance contributing to the successful completion of the first floating production, storage and offloading (FPSO) facility to operate in North American waters and more specifically the icy North Atlantic environment. Later this summer, the FPSO will be headed for the Terra Nova oilfield on the Grand Banks 220 miles east-southeast of St. John's, Newfoundland, 22 miles southeast of the Hibernia oilfield. It will be installed in water depths of 300 feet.
The Terra Nova Alliance, which is executing the major project, includes the following partners and associated responsibility:
- Vessel design and construction -- Shawmont Brown & Root ( a 50-50 joint venture between Kellogg Brown & Root and Newfoundland-based engineering firm AGRA Shawmont) and subcontractor Daewoo Heavy Industries.
- Topsides engineering and procurement - Shawmont Brown & Root.
- Topsides fabrication and hook-up - PCL Industrial Contractors Inc. in joint venture with BARMAC of Scotland, a 50 percent owned Halliburton Company.
- Turret and subsea - FMC Offshore Canada Inc.
- Commissioning and completion - Shawmont Brown & Root
- Risers and marine installation - Coflexip Stena Offshore NewFoundland Ltd. And Halliburton Subsea
- Well design and construction - Petro-Canada and Halliburton Energy Services
- Overall management - Integrated management team of all alliance members and owners
The environmental uniqueness of the Terra Nova location generated several "firsts" and special design and construction considerations. The oilfield is located on the Grand Banks where icebergs are prevalent and sea conditions pose unique challenges to/for marine installation. Consequently, the Terra Nova FPSO is the first one designed to withstand impact with a 100,000 tonne iceberg. The project also is the first to use open glory holes for the subsea equipment. These glory holes put the subsea equipment below seabed level in order to protect them from scouring icebergs.
"A key feature that separates Terra Nova from all other FPSOs in terms of design complexity is its quick disconnectible turret, which enables the FPSO to detach from its risers and moorings," according to Petro-Canada's Gregory Lever, in a paper presented at the 2001 Offshore Technology Conference.
The Terra Nova Turret --which weighs approximately 3,800 tonnes, measures 70 meters high, and accommodates 14 risers and five umbilicals-allows the FPSO to disconnect from its moorings and move off location in the event of an approaching iceberg, then reconnect once the danger passes. This is the largest disconnectible turret mooring system every built. A planned disconnection will take four to six hours, however, in an emergency the FPSO is able to leave the location in 20 minutes.
In addition to project design and environmental challenges, the project execution approach called for special considerations.
"This has been a truly global project with work being carried out in the United Kingdom, France, Norway, Korea, the Middle East and the United States and Canada," said Randy Harl, president of Kellogg Brown & Root. "The complexity and technical challenges have allowed Halliburton to bring a broad range of services to the project in a very effective way."
"Terra Nova has been a unique and challenging project," said Bob Dunsmore, Kellogg Brown & Root Project Manager. "I have been impressed with the way the integrated owner and contractor teams have worked together to overcome the challenges and get the project to this final stage of completion."
The owners of the Terra Nova development are Petro-Canada (Operator), ExxonMobil Canada, Husky Oil Operations Ltd., Norsk Hydro Canada Oil and Gas Inc., Murphy Oil Company Ltd., Mosbacher Operating Ltd., and Chevron Canada Resources.
