A method and a system 100 for re-entering a previously abandoned offshore well. A seabed location is identified that is above the well to within a tolerance. A support frame 110 is lowered onto the seabed location. A guide 120 is moved into position relative to the support frame 110, until the guide 120 is directly centred above the well. Thus, the well can be re-entered using one or more tools (400 and 410), each of which can be received by the guide 120.
The invention concerns a pipe joint formed between a pin section (10) and a box section (20); the pin and box sections each having a tubular pipe section, engaging at respective first ends in end-to-end arrangement and having a seal element partially therebetween, the box section including a collar extending from the first end, the collar being generally cylindrical, axially aligned with the tubular box pipe section and having an inner diameter of the same size as the outer diameter of the pin section, enabling the collar to be placed about the pin section, the pin and the box sections being secured together by means of a plurality of securing means housed in the collar and actuable to exert radial pressure to urge the pin and box into scaling arrangement, the collar (22) of the box section (20) including a test port, comprising a housing atrium, defined by an atrium wall, housing a test plug (60); the housing atrium (61) and the seal element (53) being fluidly linked by a box conduit; the plug comprising a plug body and a plug seal housed between the plug body and the housing atrium wall to seal the housing atrium from atmosphere and having therethrough a plug conduit connectable at a first end to a pressure test apparatus and fluidly linkable at a second end to the box conduit; the plug being moveable between a first position forming a fluid link between the plug conduit and the box conduit, and a second position closing the fluid link.
A pipe joint formed between a pin section and a box section. The pin and box sections each have a tubular pipe section, engaging at respective first ends in end-to-end arrangement and have a seal element partially therebetween. The box section includes a box stress collar extending from the first end, the box stress collar being generally cylindrical, axially aligned with the tubular box pipe section and having an inner diameter of the same size as the outer diameter of the pin section, enabling the box stress collar to be placed about the pin section. The pin and the box sections are secured together by means of one or more securing means housed in the box collar and actuable by exertion of radial pressure to urge the pin and box into sealing arrangement.

A tensioning unit for a conductor is disclosed. The unit houses a load transition plate, which fits about and grips the outer circumference of a conductor. The plate comprises at least 2 sections securable together about a conductor to facilitate fitment, the plate being mounted to a mounting means, for movement to exert a generally axially directed tensile force on a conductor. The mounting means comprises a plurality of hydraulic cylinders actuable by a hydraulic power unit and hydraulically linked to one or more accumulators. Also disclosed is a skid crawler unit for moving a large load laterally. The skid crawler unit comprises a motile unit, mounted for movement along a linear track which has a plurality of reaction nodes, optionally proud of the track or alternatively below the track surface. One or more hydraulic cylinders are mounted to the motile unit and coupled to a reaction element for coupling to a load, actuation of the cylinder against the element inducing a motive force on the motile unit. The motile unit includes an engagement element to releasably engage a reaction node.
