Gravity-based structure

These structures are often constructed in fjords due to their protected area and sufficient depth.

Prior to deployment, a study of the seabed must be done to ensure it can withstand the vertical load from the structure.

Notable GBSes include the 1997 Hibernia Gravity Base Structure off Newfoundland.

Around 2020 GBSes became the fashion for Novatek's exploitation of the petroleum resources in the Gulf of Ob.

As of 2010, 14 of the world's offshore wind farms had some of their turbines supported by gravity-based structures.
