The present invention relates to methods of inserting and removing tools and/or robots into/from inside subsea oil wells. In this scenario, the present invention provides a system for insertion and removal of a device (30) in a subsea oil well (20), said system comprising (i) a WCT assembly (10) comprising a removable protective cap (40) and (ii) a WCT tool (50) connected to a receptacle (60) comprising within it the device (30), wherein the WCT tool (50) is suitable for being inserted in the place where the protective cap (40) is coupled, wherein at least one of receptacle (60) and WCT tool (50) is able to be opened or closed, releasing the device (30) into the subsea oil well (20) or retaining same inside the receptacle (60). The invention further provides methods of inserting and removing a device (30) into/from a subsea oil well (20).

A pig diverter comprises a hollow housing having a flowline inlet port, a flowline outlet port, a pig entry opening, and a pig exit opening, all communicating with the interior of the housing. A tubular pig holder enclosed by the housing is pivotable between a receiving position and a launching position. In the receiving position, the pig holder is aligned with the pig entry opening to receive a pig and effects fluid communication between the pig entry opening and the flowline outlet port. In the launching position, the pig holder is aligned with the pig exit opening to launch a pig and effects fluid communication between the flowline inlet port and the pig exit opening.

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.
