Advanced Tension Frames (ATF) are used for well intervention operation on floaters such as semi-submersible rigs and drill ships. Due to relative movement between riser system and rig, it is necessary to keep the riser in tension and at the same time offer a work window for personnel. Typically this involves rigging up the BOP, Lubricator or Injector inside frame, and change of bottom hole assemblies.
The Dwellop Advanced Tension Frames are designed to achieve maximum level of safety, and at the same time give better operational efficiency and predictability. Our concept provide optimum work conditions for running Coiled Tubing operations, enabling various type injectors and optional side skidding functions for operation on off centre bores. The Advanced Tension Frames enhances wire line operations as well, either by skidding the Injector Lifting Table off centre with the Injector still installed, remove the Injector from the Injector Lifting Table and skid aside, or if necessary, remove the Injector Lifting Table.
The frames can be delivered with various lengths, telescopic, heave compensated and with radio remote operated or hydraulic operated.
