Overview
Precision Subsea Rock Bag Installation Using a Dedicated Installation Frame
In response to the growing demand for safe, repeatable and cost-effective rock bag installation subsea, Seatools has developed the Subsea Lifting Frame (SLF). This advanced rock bag installation tool allows contractors to transport, position and install subsea protection products with a high degree of accuracy and operational control.
Rock bags and filter bags are commonly used for subsea cable protection, pipeline stabilization and scour protection around offshore structures. The remotely operated SLF facilitates highly automated installation operations and enables installation contractors to achieve significant time savings – a critical parameter when performing capital-intensive offshore installation operations.
Drawing upon Seatools’ extensive capabilities in the field of subsea positioning and control engineering, the SLF features automatic heading control. The SLF lifting beam can be upgraded with automated position control, for precision positioning of scour protection products without the need for either divers or a WC-ROV. This significantly boosts both operational safety as well as efficiency.

Key features
-
Enables safe installation operations
No more need for divers, thereby significantly improving operational safety.
-
Reduced cycle
timesIrrespective of the environmental conditions (e.g. strong tidal streams), subsea mattress installation can be executed extremely efficiently, thanks to auto heading and auto positioning features.
-
Fail safe system
designThe Intelligent Subsea Lifting Frame features a dual redundant release mechanism. In the unlikely event of hydraulic system failure, the release mechanism can be actuated by means of a WC-ROV.
