The disclosure relates to an electrically powered mobile fluid supply system (MFSS) for supplying fluid to a host unit. The MFSS comprises at least one pressurized fluid volume, a fluid dispenser fluidly connectable to the host unit and configured to supply fluid from the at least one pressurized fluid volume to the host unit in a fluid supply operation, and at least one compressor configured to build sufficient pressure for the fluid supply operation in the MFSS. The MFSS is configured to be electrically connected to the host unit and the at least one compressor is configured to be electrically connected to the MFSS and electrically powered by the host unit during the fluid supply operation.

The disclosure further relates to a method for supplying fluid to a host unit, to a control unit configured to control the fluid supply operation, and to the MFSS.

A method includes providing a length of pipeline that has a housing defining a central bore extending the length of the pipe and a space formed within the housing and extending the length of the pipe. At least one condition within the space is continuously monitored within the space to detect in real time if a change in the housing occurs.

A shut-off device for a pipe in a pipeline and responsive to ingress of water, has at least two valves for installation in the pipe of the pipeline. Each valve has a valve member supported for movement between an open position when the valve is open for passage of a fluid through the pipe, and a closed position when the valve is closed for preventing passage of the fluid through the valve. The device includes a buoyant member associated with the valve members for causing movement of the valve members to the closed positions upon ingress of water to the buoyant member. The valve members are moved to the closed positions in respective upstream and downstream directions of passage of the fluid through the pipe.

Described embodiments include a system and a method. A described system includes a pipeline system. The pipeline system includes a transportation conduit containing a natural gas hydrate flowing from a first geographic location to a second geographic location. The pipeline system includes a cooling conduit running parallel to the transportation conduit, and having a heat-transfer surface thermally coupled with the flowing natural gas hydrate. The cooling conduit contains a heat-transfer fluid flowing between the first geographic location and the second geographic location. The flowing heat-transfer fluid has a target temperature range predicted to maintain a selected stability of the flowing natural gas hydrate.
