ROV Installation services

ROV Installed

Fabric Formwork solutions can be provided for ROV installation wherever possible. ULO service includes supply of fabric formwork, deployment basket and subsea grouting manifold together with personnel to operate the grouting equipment and to instruct the ROV solutions in the deployment frame.

ROV Clamp System

The Fabric Formwork is folded and fixed to a hydraulically operated pallet with clamps to hang the system on the pipeline at the freespan location.

The ROV pulls the pallet to the pipeline, attaches the system to the pipeline and releases the fixing system.

The Fabric Formwork unfolds and grouting can commence.

After completion of Grouting the ROV removes the pallet from the pipeline and the system can be recovered for reuse.

ROV Sled System

The Fabric Formwork is fixed to a sled with two vertical columns and placed onto a deployment pallet with grouting manifold.

On seabed the ROV pulls the sled system to the pipeline until the vertical columns are touching the pipeline at the freespan location.

After completion of grouting the ROV disconnects the grout hose from the grouting manifold and the pallet can be recovered for reuse.
