There is disclosed a tubing expansion device and a method of expanding tubing. In one embodiment, an expansion device () is disclosed which comprises at least one expansion member () adapted to expand a tubing () by inducing a hoop stress in the tubing (), and at least one further expansion member () adapted to expand the tubing () by inducing a compressive yield of the tubing (); and a method of expanding tubing () comprising the steps of expanding the tubing () at least in part by inducing a hoop stress in the tubing (), and expanding the tubing () at least in part by inducing a compressive yield of the tubing ().

Tubing expansion

A well servicing tool storage system for subsea well intervention is disclosed which provides a tool storage means as part of the intervention system and which has a plurality of tool storage arms deployed around the tool storage means. Each arm has a clamp capable of clamping a tool, and moving the clamped tool between a stored position near the perimeter of the tool storage means, and a deployed position in the centre of the tool storage means where the tool can be made up into a wireline connection.
