The majority of the construction was performed at a site in Bull Arm, Trinity Bay, Newfoundland and Labrador. The platform sits atop an enormous gravity base structure (GBS) that sits on the ocean floor. After studying the possibility of integrating a liquefaction plant with such a structure, Pascal Collet and Aroquiaradj Gervais from the LNG product line explain the whys and wherefores of this solution. Doris Engineering's expertise in concrete designs for the offshore industry will be tested early next year, when Norway's Troll Olje project comes onstream. This site uses cookies. suncor.com.

The gravity based platform is ~345 feet across. Mazagon Dock Shipbuilders Limited (MDL), formerly called Mazagon Dock Limited, is a shipyard situated Mazagaon, Mumbai. nrc-cnrc.gc.ca. Morrison Hershfield is an employee-owned professional services firm providing engineering and management consulting services in the areas of energy and industrial, buildings, technology and telecom, transportation, environment, water and wastewater, and land development. These sub-sea solutions may consist of one or more subsea wells or of one or more manifold centres for multiple wells. The U.S. Department of Energy's Office of Scientific and Technical Information When asked what could go wrong, he smiled. The Hibernia offshore oil platform is the first major platform for the development of hydrocarbon reserves on the Grand Banks off the East Coast of Canada. Today, the oil storage tank integrated into the GBS has been filled and emptied several times, the crude treated on the platform Topsides facilities and exported by tanker. Client: NODECO / Hibernia Management and Development Company … WikiMili Hibernia Gravity Base Structure The Hibernia Gravity Base Structure is an offshore oil platform, on the Hibernia oilfield south east of St. John's, Newfoundland, Canada.. A Significant Discovery Area for the Hibernia field was officially declared on October 2, 1985. A gravity-based structure (GBS) is a support structure held in place by gravity. It attempted to climb aboard the 600,000-tonne gravity base structure. The first concrete oil platform has been installed in the North Sea in the Ekofisk field in 1973 by Phillips Petroleum. The platform is 224 meters high, and it has three separate components, topsides, gravity base structure and offshore loading system (OLS). The production platform Hibernia is the world's largest oil platform (by weight) and consists of a 37,000 t (41,000 short tons) integrated topsides facility mounted on a 600,000 t (660,000 short tons) gravity base structure.The platform was towed to its final site, and 450,000 t (500,000 short tons) of solid ballast were added to secure it in place. The Hibernia gravity base structure was floated out from dry dock in Newfoundland last November. Jeanne d'Arc" on out-dated bathymetric charts and which was once thought to represent a local exposure of basement rocks similar to the Virgin Rocks. [2]. suncor.com. A 600 kilotonne gravity base structure built after the Ocean Ranger disaster, it sits in 80 metres (44 fathoms) of water directly on the floor of the North Atlantic Ocean 315 kilometres (196 mi) off of St. John's, Newfoundland. Construction of the Hibernia Gravity Base Structure (GBS) and assembly of the Topsides and associated Topsides-mounted structures occurred in Bull Arm, Trinity Bay, Newfoundland and Labrador. The Strait of Belle Isle separates the province into two geographical divisions, Labrador and the island of Newfoundland. For many reasons, the operators of the field, first MOBIL OIL CANADA, then HMDC (Hibernia Management & Development Company), selected the fixed Gravity Base Structure option (GBS). The Hibernia platform has three separate components: Topsides, Gravity Base Structure (GBS), and Offshore Loading System (OLS). Media in category "Hibernia Gravity Base Structure" The following 2 files are in this category, out of 2 total. The Hibernia Gravity Base Structure is an offshore oil platform on the Hibernia oilfield southeast of St. John's, Newfoundland, Canada. It later attempted to climb onto the Hibernia gravity base structure. Its unique gravity base structure and extraordinary supermodular topsides have been completed, mated, and towed out to the production site on Newfoundland's Grand Banks. This platform is one of the most complex structure which has ever been engineered and built. At full load, it will displace more than 600,000 tonnes, more than five times the displacement of a Nimitz-class aircraft carrier. Offshore Newfoundland, Canada. This basin formed in response to the large scale plate tectonic forces that ripped apart the super-continent Pangea and also led to sea-floor spreading in the North Atlantic Ocean. The Hibernia gravity base structure was designed using HPC made with a Type 10 SF cement (Type 1 ASTM cement containing 7%–8% silica fume) and a polynaphthalene superplasticizer, in order to resist the impact of huge icebergs (Hoff & Elimov, 1995; Woodhead, 1993). This is the first platform ever designed to resist the impact of drifting icebergs. Pioneering Spirit is the world's largest vessel by gross tonnage. The completed platform was towed to the Hibernia oil field and positioned on the ocean floor in June of 1997, and began producing oil on November 17, 1997. These structures are often constructed in fjords since their protected area and sufficient depth are very desirable for construction. There were significant challenges faced by the engineering firms Doris Development Canada, Morrison Hershfield and Mobil Technology in developing a structural solution with adequate strength which was also constructible. To resist or to dodge? It has been widely reported that the Hibernia Platform has been installed during Summer 1997 at its final operation site, 315 km offshore Newfoundland. Media in category "Hibernia Gravity Base Structure" The following 2 files are in this category, out of 2 total. The Hibernia Gravity Base Structure is the world's largest offshore oil platform, on the Hibernia oilfield. When it was initially proposed for development, the field had an … Hibernia is an oil field in the North Atlantic Ocean, approximately 315 kilometres (196 mi) east-southeast of St. John's, Newfoundland, Canada, in 80 m of water. suncor.com. Concrete Gravity Based Structure Coastal Labrador Natural Gas Extraction Midterm Report. The platform stands 224 metres high, which is half the height of New York's Empire State Building … The Golden Eagle oilfield is an offshore oil field in Scottish territorial waters in water depths of up to 114 metres (374 ft).
