ROV POWERED STANDALONE SUBSEAINTERVENTION SYSTEM
SUBSEA TEST & FLUSH UNIT
Description 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 gre-ater 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.
