Subsea Test & Flush Unit (STFU) is a standalone subsea intervention basket powered by a workclass ROV. Giving the benefit of performing workover- & intervention tasks without need of additional topside equipment such as umbilical, HPU, Control Cabin and winch. All powered thru ROV HFL/EFL jumpers.
The STFU system is an alternative product to an RWOCS/AHPU ROV mounted skid, giving the benefit to add greater volume of control fluid, increased number of direct hydraulic outputs as well as flexibility to the ROV by removing need of an underslung mounted skid. The STFU basket is a high class multi modular intervention system built with field proven components and DNV 2.7-3 certified frame to allow cost efficient and HSE-beneficial subsea operations.
