A remote operated underwater vehicle, ROV, is provided, where the ROV includes at least one extendible pair of tubulars supported on the ROV, the one tubular of the pair being movable longitudinally relative to the other tubular of the pair, for extending a combined reach of the tubulars; and at least one pump connected to the tubulars, the pump being operable for pumping or suctioning fluid through the pair.

The invention presents a system and method for reducing pressure and draining the annulus of submerged flexible pipes, with application in all flexible pipe structures and in any industry that uses these types of pipes. Its objectives are to eliminate condensed water and reduce the partial pressure of CO.sub.2, thus restoring the integrity of the pipes. In addition, with the reduction of the pressure of the annulus gases, the operations of collection of the pipes can be carried out with greater speed, that is, in less time. The previous relief of the annulus pressure further reduces the risk of rupture of the outer cap during the operation, thus reducing the risk of exposing operators to the presence of harmful gases, when the pipe reaches the deck of the PLSV vessel.

A subsea well intervention cap is provided. The subsea well intervention cap includes a frame, a first clamp segment coupled to the frame and configured to be fitted over a horizontally oriented flowpath of a subsea well equipment component, and a second clamp segment having a rim segment configured to interface with the first clamp segment, wherein the second clamp segment is movable with respect to the first clamp segment. The subsea well intervention cap also includes an actuation mechanism coupled to the frame that actuates the second clamp segment in a vertically upward direction and in an axial direction with respect to the frame toward the first clamp segment. The subsea well intervention cap is lightweight and able to be installed on subsea well equipment using a standard remote operated vehicle (ROV).

The invention provides a subsea oil and gas production installation, methods of installing the installation and methods of use. The installation comprises a subsea production system comprising a first production pipeline and a second production pipeline, a first subsea manifold in fluid communication with the first production pipeline comprising a fluid access interface and a flowline connector, a removable module fluidly connected to the fluid access interface of the first subsea manifold and configured to receive production fluid from one or more subsea wells and a second subsea manifold in fluid communication with the second production pipeline. The first subsea manifold defines a first flow path between the fluid access interface and the first production pipeline and a second bypass flow path between the fluid access interface and the flowline connector. The first and the second subsea manifolds are fluidly coupled to one another by a connecting flowline which is connected at a first end to the flowline connector of the first subsea manifold. The removable module comprises a flow control means operable to selectively route the production fluid from one or more subsea wells into the first production pipeline via the first flow path defined by the manifold, and/or into the second production pipeline via the second bypass flow path, the connecting flowline and the second subsea manifold.
