The system (10) for the transfer of fluid comprises a tubular fluid transfer line (2) comprising at one of its ends a coupling system (32) adapted to be connected to a target duct (33) for the transfer of fluid, and electrical actuators (11-13) for controlling the movement of the transfer line in space, each via an actuating shaft, characterized in that each of the actuators for controlling the movement of the transfer line comprises an electric motor with an output shaft, a speed reducer, the actuating shaft being rotationally driven by the motor output shaft by means of the speed reducer, which is reversible, so as to enable the actuating shaft to turn when an actuating torque is directly applied to it, and braking means for locking the actuator in position when movement control is in course and that actuator is not activated for that control.

A system, methods, and apparatus for preventing receptacle overfilling are presented. The system can include a sensor member configured to couple with a receptacle and sense a material level within the receptacle, such as via a sight glass of the receptacle. The system can include a controller in operable communication with the sensor member and configured to instantiate the shutoff of material flow from a material dispensing system if a particular material level is detected by the sensor member. The system can include an intermediate member configured to relay communications between the sensor member and the controller. The intermediate member can be coupled to a fluid line and can further act as a holster for the sensor member, such as by facilitating the coupling of the sensor member to the intermediate member and/or the fluid line.

A system for transferring a fluid includes a transfer line connecting a storage tank and an LNG carrier, a loading arm provided on the transfer line, an emergency shutoff device configured to shut off the transfer line, a bypass line connecting the transfer line and the storage tank, and a bypass valve provided in the bypass line. The storage tank includes a fluid reception pipe configured to receive the fluid from the outside and a BOG pipe configured to discharge a boil-off gas of the fluid generated in the storage tank to the outside, and the bypass line is connected to at least one of the fluid reception pipe or the BOG pipe.

An input includes a specified fluid product to be transported, a specified volume transfer of the specified fluid product to a berth, and a target flow rate of the specified fluid product. A first allowable operating range for volume transfer and a second allowable operating range for flow rate are determined at least based on: the specified fluid product, an availability of meters for metering, an availability of loading arms for loading the specified fluid product to a ship located at the berth, and an availability of vapor combustion units for flaring. A control signal is transmitted to at least one of multiple valves to establish a flow path for the specified fluid product. A start signal is transmitted to initiate a recipe that controls flow through the flow path within the first allowable operating range and the second allowable operating range.
