Bull Arm Fabrication, Atlantic Canada’s largest industrial fabrication site, is located 150 kilometres from St. John’s in Trinity Bay. It is the primary construction site for the Hebron Project’s gravity base structure (GBS) and the topsides living quarters (LQ) module.
The Hebron GBS consists of a reinforced concrete structure designed to withstand sea ice, icebergs and meteorological and oceanographic conditions and can store approximately 1.2 million barrels of crude oil.
The individual modules that make up the “topsides” of the GBS will be put together at Bull Arm. These modules, which are constructed separately and brought to Bull Arm, include:
- Utilities process module (UPM)
- Drilling support module (DSM)
- Drilling equipment set (DES)
- Living quarters (LQ) module *
- Lifeboat stations
Once complete, the integrated topsides and the GBS will be floated individually to a deepwater work site where the topsides will be installed on top of the GBS.
Fabrication and other work associated with the Terra Nova FPSO, the White Rose project, the Hibernia project, the Voisey’s Bay nickel project and the Henry Goodrich drill rig has been completed at Bull Arm Fabrication. It was also the construction site for the Hibernia GBS in the mid-1990s.
*the Living Quarters (LQ) module is already at Bull Arm, as it was constructed there.
