Stop Collar

Stop Collar

The Stop Collar can be used to firmly hold buoyancy elements in position axially on a riser joint, to prevent the buoyancy from sliding along the tube of the riser when it is in an up-right position.

The Stop Collar has an internal profile and can be positioned within the profile of the buoyancy elements or riser protection modules, without increasing the external profile and ensuring they are not exposed.

Designed to fit around any diameter riser joint main tube with a customisable design, the Stop Collar can be used with Drill Riser Buoyancy Modules or Riser Guard protection.
