The invention relates to a method (300) of estimation of a probability of damage caused by sloshing of a liquid load during an operation to transfer said liquid load from a first floating structure (1) to a second floating structure (40), the first floating structure (1) and the second floating structure (40) being associated with one another during said transfer operation so that the first floating structure (1) and the second floating structure (40) are oriented with a common bearing (99). The method includes steps (307) of estimating a probability of damage to at least one tank of at least one of said first and second floating structures (1, 40) and (308) of supplying information to a user as a function of the probability of damage estimated in this way.

An overfill protection means for storing liquefied gases in a tank container, comprising a housing into which the filling line runs for filling the tank container, a closure which is arranged so as to be movable between a closing position preventing filling and an open position releasing filling, and a float, which float is coupled to a trigger mechanism. The trigger mechanism is movable by the float between an engaged position and a release position depending on the liquid level in the tank container, wherein, in the engaged position, the trigger mechanism engages the closure and keeps the closure in the open position, while being supported on the housing, and wherein, in the release position, the trigger mechanism releases the closure, whereby the closure is movable into the closing position by the flowing liquefied gas.

A dual-purpose displacer for adjusting a liquid cryogen level in a cryostat, the dual-purpose displacer includes a displacer wall having an exterior displacer surface and an interior displacer surface. The interior displacer surface defines a displacing chamber configured to contain a first portion of liquid cryogen. The exterior displacer surface is configured to displace a second portion of liquid cryogen contained in a cryogenic chamber of the cryostat. The dual-purpose displacer is disposed within the cryogenic chamber of the cryostat and configured to transfer the first portion of liquid cryogen contained within the displacing chamber to the cryogenic chamber.

The invention relates to a of processing a liquid natural gas stream at a LNG import terminal. The method comprises operating a vaporization unit obtaining a pressurized vaporized natural gas stream and operating a slushification unit to obtain a slush of liquid and solids and a cooled vapour phase. The method further comprises withdrawing the cooled vapour phase from the slushifier providing a cooled vapour stream and passing the cooled vapour stream to the vaporization unit.

A dosing vessel includes a reservoir having an inlet and an outlet and is configured to contain a supply of a cryogenic liquid with a headspace above. The outlet is configured to be connected to a dosing arm having a dosing head. A low pressure sensor is configured to detect a vapor pressure in the headspace. A high pressure sensor is configured to detect a pressure in a bottom portion of the reservoir. An inlet valve is in fluid communication with the inlet of the reservoir and is placed in communication with a source of cryogenic liquid. A controller is in communication with the high and low pressure sensors and the inlet valve and is configured to store a preset liquid level or a preset differential pressure corresponding to the preset liquid level, to determine a measured differential pressure based on data from the high and low pressure sensors and to control the inlet valve based on the measured differential pressure and the preset liquid level or the preset differential pressure so that a liquid level of a cryogenic liquid stored in the reservoir is generally maintained at the preset liquid level.

Disclosed are a fuel supply system and method for a ship engine. The fuel supply system for a ship engine of the present invention comprises: a submersible pump which is provided to an LNG storage tank of a ship for supplying LNG to the engine of the ship; a high-pressure pump which has the LNG supplied thereto from the submersible pump and pressurizes the same under high pressure; and a return flow channel which, at the upstream of the high-pressure pump, returns the LNG to the LNG storage tank, wherein the flow of the LNG returning through the return flow channel is controlled, and the temperature of the LNG is controlled at the front end of the high-pressure pump.

A dual-purpose displacer for adjusting a liquid cryogen level in a cryostat, the dual-purpose displacer includes a displacer wall having an exterior displacer surface and an interior displacer surface. The interior displacer surface defines a displacing chamber configured to contain a first portion of liquid cryogen. The exterior displacer surface is configured to displace a second portion of liquid cryogen contained in a cryogenic chamber of the cryostat. The dual-purpose displacer is disposed within the cryogenic chamber of the cryostat and configured to transfer the first portion of liquid cryogen contained within the displacing chamber to the cryogenic chamber.

A gas-flow cryostat adapted for dynamic temperature regulation using a fluid level sensor; the cryostat further including one or more heaters coupled to various components of the cryostat. As fluid evaporates from a liquid cryogen evaporation reservoir within the cryostat, the fluid level sensor and a feedback control unit are adapted to monitor and dynamically control the level of evaporating cryogen by regulating the heaters. Accordingly, the cryostat is adapted to dynamically control temperature about a specimen region within the cryostat. The cryostat can be used in various applications, including analytical laboratory equipment for measuring various physical properties of samples. Temperature sensors are further incorporated for added control and optimization of the cryostat.
