Abstract: A well intervention monohull vessel and method of use including a tower type open derrick structure disposed on a deck of the vessel and a sole point land out having a sole point of riser tension contact with a top of the derrick structure. The vessel may also include subsea equipment such as an intervention riser system and an emergency disconnect package, a moon pool door preferably capable of transporting the subsea equipment, an intervention lift frame, a surface coiled tubing reel, a riser storage area, a rail, a pallet, a subsea tree, a crane, and/or drawworks.

Abstract: A coiled tubing lifting frame (10) for deploying coiled tubing in a riser (32). The coiled tubing lifting frame (10) comprises a coiled tubing injector (12) and the frame (10) is configured to position the coiled tubing injector (12) relative to a support (44). The coiled tubing lifting frame (10) is configured to support the riser (32). Methods of deploying a riser (32) and coiled tubing in a riser (32), including supporting the riser (32) with a coiled tubing lifting frame (10).

Abstract: A lifting method comprising supporting a payload (20) using a first lifting apparatus (18); and activating an emergency lifting apparatus (14) to raise the payload a predetermined distance in response to an emergency signal. The emergency lifting apparatus is configured to be activated to lift the payload a predetermined distance in response to an emergency activation signal. The method and apparatus are particularly useful in the event of a failure of the first lifting apparatus: the emergency lifting apparatus may be activated to lift the payload a relatively small distance sufficient to clear adjacent structures. This may be particularly advantageous in offshore operations, where the first lifting apparatus is supported on a floating vessel which will experience heave.
