The GSF Grand Banks is an Aker H3.2 semisubmerisble drill rig currently owned by Transocean (though the GSF refers to GlobalSanteFe ). It was built in 1984 by St. John Shipbuilding , Canada. It was originally known as the Bow Drill 3 (1984-1988), which changed to Maersk Vinlander (1988-1998) and Glomar Grand Banks (1998-2004) before its' current moniker. It has particular importance to the Newfoundland offshore industry, where it drills alongside the Henry Goodridge . It had drilled and located oil in the Hebron field in 1998, and more recently in the White Rose field. Currently, it is drilling for Husky on the North Amethyst project [1]
