Actuator Running Tool
The Actuator Running Tool (ART) is designed and tested for retrieval and installation operation of subsea hydraulic actuators up to 10.500 kg.
Description
The actuator running tool is landed on subsea structure using configurable guideposts and mini-guideposts for fine guiding. Integrated soft-landing cylinders ensure controlled landing speed. The lifting operation within ART is hydraulically operated through a standard API 17H Hot Stab receptacle. Connection to actuator is done by clamping, and is operated by a API 17H Class 4 Torque Tool. Interlocks are mechanical and operated by ROV.
Key features
- DNV 2.7-3 Lifting frame
- Up to 5° landing angle
- Adjustment mechanism integrated
ART has successfully been tested with 5° offset on landing base, and integrated adjustment cylinders (pitch, roll, x- and y-plane movement) can be used for alignment with valve.
