The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The present submersible water lifting assembly can comprise a High Pressure Recovery Turbine Pump (7/7A) that utilizes under water arrangements of an unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of an existing water injection system; eliminating the requirement of diesel engine driven pump, for the lifting the water. It avoids fire risk on the safety system itself, even under the conditions of a large fire, unlike that of the prior art.

A method includes locating a first set of electromagnetic field emitting devices in a vicinity of the pressure source, using the first set of electromagnetic field emitting devices to generate a first electromagnetic field in a first shape that forms an enclosure containing the pressure source, pumping a magnetic fluid into the enclosure at a pumping pressure, and increasing the pumping pressure to overcome the pressure from the pressure source.

A well system and method including applying suction to a wellhead housing outlet (8) to divert the flow of subterranean gas from flowing through a gas conduit through the wellhead housing (4). An operation can then safely be performed on a component (e.g. removing a hanger) of the wellhead apparatus. Well gas can be diverted to a flare system (200). Suction can be applied by a venturi system including eductors (104, 106). The method may include opening the gas conduit outlet once a pressure sensed at the conduit outlet is negative. Suction may also be applied to an upper outlet (14).

Systems and methods for extinguishing a hydrocarbon well include a housing with an inner chamber sized for placement over a wellhead member. The inner chamber extends from a base of the housing to a roof of the housing. An extinguishing materials injection system is operable to deliver extinguishing materials to the inner chamber of the housing. A valve is located at the roof of the housing. A ram sealing system is located at the base of the housing. The ram sealing system has a pair of rams, each ram having an engaging surface. The engaging surface is sized and shaped to seal around the wellhead member when the ram sealing system is in a closed position. The pair of rams are rotationally attached to a ram body. An arm link rotationally links each ram to the ram body.
