Offset installation

Offset installation equipment is currently being developed and tested for use in the event of a subsea well incident where vertical well access by vessel is not possible.

It is planned to enable responding personnel to remove debris or install capping, containment or related equipment at a safe offset distance from an incident site.

The offset installation equipment includes a carrier with adjustable buoyancy provided by ballast tanks and positioning is controlled through mooring and pennant lines. It can be used to install or remove capping, containment or related equipment in water, without direct vertical access. It can also be fitted with shears to support debris clearance operations. The equipment has a working depth range of 75m to 600m, and can be deployed up to 400-500m offset from an incident well.

The equipment is expected to be delivered in 2017.
