The invention relates to a gate valve assembly (20) for use in a subsea workover system comprising: —a valve block (22) having a flow path (21c); —valve seats (33, 34) located within the valve block (22) around a periphery of the flow path (21c), —a gate valve member (40) which is moveable across the flow path (21c) between a first position in which the flow path (21c) is open and a second position in which the flow path (21c) is closed; —said gate valve member (40) comprising a first portion (31) surrounding an opening (32) adapted to mate with the flow path (21c) when the gate valve member (40) is in the first position, said first portion (31) is provided with a cutting member (30) arranged on the periphery of the first portion (31) towards the opening (32). The gate valve member (40) further comprises a second portion (41) having at least one recessed part (42, 43), said recessed part (42, 43) being positioned such that when the gate valve member (40) is in the second position, the gate valve member (40) and the seats (33, 34) forms a sealing area (44, 45) arranged on a planar surface of the gate valve member (40).

A multi-intervention blowout preventer includes a body having a bore therethrough. A first pair of ram blocks may be coupled to the body and include a ram, a catcher, and a blade operationally connected to the bore via a first pair of openings in the body. The ram, the catcher, and the blade may cut a flexible line extending through the bore while holding the flexible line. A second pair of ram blocks may be coupled to the body and include a second pair of rams operationally connected to the bore via a second pair of openings in the body to seal around a tubular. A third pair of ram blocks may be coupled to the body and include a third pair of rams operationally connected to the bore via a third pair of openings in the body to seal the bore.

According to some embodiments, systems and methods of releasing a wireline from a tool string in a well are presented. For example, a wireline release tool may include a first housing portion and a second housing portion. The first housing portion may have a closed end, an open end, and a chamber therebetween, and the second housing portion may be shearably attached to close the open end of the first housing portion. A gas generator may be disposed in the chamber and may be capable of generating gas pressure in the chamber sufficient to overcome a pressure differential between the chamber and the external wellbore environment and to force the second housing portion from an initial position to a release position. One of the housing portions may be configured for attachment to a wireline, while the other of the housing portions may be configured for attachment to a tool string.

A ball valve assembly includes a ball having a fluid pathway and a leading edge portion. The ball is configured to rotate between an open position and a closed position, the fluid pathway is configured to align with a fluid passage while the ball is in the open position, and the fluid pathway is configured to be offset from the fluid passage while the ball is in the closed position. Furthermore, the leading edge portion includes a first leading edge configured to cut a line extending through the fluid pathway as the ball rotates from the open position to the closed position, the leading edge portion includes a second leading edge configured to engage a seal of the ball valve assembly as the ball rotates from the open position to the closed position, and the first leading edge is positioned radially inward from the second leading edge.
