Drill Riser Buoyancy - Drilling - Trelleborg Offshore

Drill Riser Buoyancy

The drill riser provides a conduit for the drill string and drilling fluids from the ocean floor to the rig. This has significant weight which must be supported by its own structure and ultimately by the drilling vessel. In order to reduce this weight in water to a more manageable amount, discrete buoyancy units are fitted along the length of the riser.
