HIBERNIA GRAND BANKS, CANADA
Hibernia is found East of St. John's, Newfoundland. This field
is holding reserves around 610 to 620 million bbl. It is on where two other fields existed and is considered the
light good oil.
Hibernia was built iceberg resistance in mind and envisioned on reduced damage if a collision would occur.
Doris Development Canada received the subcontract in late 1990, to being the gravity based structure. While being
specially reinforced to withstand the adverse area it was to live in, Hibernia also received special tie wall structural
designs and weighing in around 450,000 tons. With storage on GBS is set to around 1 ½ million bbl of crude
oil, allowed for longer production then what was originally estimated before offloading had to occur.
Each dill house had capacity to hold up to 32 drill slots, allowing it to reach deep down into the oil field below.
The topside was built as a 5 super module system and 7 sub buildings.
Over half of the topside super modules were constructed at Bull Arm, with the remaining being built and subbed
out around the world. Offloading of crude oil will mainly fall onto the job of a sub sea pipe network, then filling
a specialty tanker for the remainder of the crude's trip.
Hibernia is estimated to produce around 150,000 b/d. |

The gravity base structure (GBS) at the deepwater site
consists of a 105.5m concrete caisson, constructed using high-strength concrete, reinforced with steel rods and
pre-stressed tendons.
