Serving the drilling and downhole market for well over forty years, Trelleborg Offshore has an extensive range of reliable, cutting-edge polymer engineered products and solutions.
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.
Riser accessories are designed to complement the rigid Drill Riser Buoyancy Modules (DRBMs) so that there is a comprehensive level of support while ensuring a seamless installation of the riser system.
Riser Protection, protects people, structures and equipment from all types of fire and corrosion in the offshore environment, as well protecting the riser itself. In the demanding environment offshore it is paramount to ensuring on-board safety.
Crushable Foam Wrap is designed to be installed around the inner drill casing which is then immersed within the annulus fluid. As the pressure of the annulus fluid increases, the Crushable Foam Wrap will collapse at a pre-determined pressure/temperature combination, allowing expansion of the annulus fluid and dispersing any potentially destructive pressure increases
