Description

FIELD OF THE INVENTION

[0001] The present invention relates to a blowout preventer for being mounted on a well head, comprising a plurality of valves arranged in fluid communication with each other, connected and forming a tubular pipe. Furthermore, the invention relates to a launcher system, a well intervention module, a well intervention system and a well system.BACKGROUND ART

[0002] During production of oil, it may become necessary to perform maintenance work in a well or to open a production well. Such well work is known as well intervention. Inside the well, a production casing is placed which in its upper end is closed by a well head. The well head can be situated on land, on an oil rig or on the seabed below water.

[0003] When a well head is situated on the seabed on deep water, well intervention is more complicated since visibility below water can be poor. Furthermore, the weather conditions at sea can interfere with the accomplishment of an intervention and, in case of a rough se...
