An LNG production plant and a method of constructing the LNG production plant is disclosed. The LNG production plant includes at least one plant module and a support structure to support the plant module. Each plant module is dry transported by a heavy lift vessel and subsequently transferred to the support structure without lifting the plant module from a deck of the vessel. The support structure includes a landing substructure onto which the plant module is transferred from the vessel. Landing substructure may be onshore or offshore. The support structure may also include one or more onshore support substructures and a transfer path enabling a plant module to be moved from the landing substructure to a corresponding onshore support substructure.

An intelligent controls system for remotely monitoring and controlling a chemical process is disclosed. The system comprises a piece of remote field equipment for performing the chemical process, a user device, a server, and program codes to perform the steps of establishing an equipment-server and a client-server connection, receiving a set of chemical process input parameters and a set of desired chemical process output parameters, controlling a set of chemical process control parameters to achieve the desired chemical process output parameters, and providing an interface to allow an operator to manually control and/or manually override the set of chemical process control parameters. The controls system allows any piece of remote field equipment for performing complex chemical processing to be monitored, controlled, and operated remotely. A large array of distributed field equipment situated around the world can all be controlled primarily through a single interface provided in a central control center.

Disclosed are a system and method for reliquefaction of boil-off gas of a ship and a system and method for treating off-gas of a reliquefaction apparatus. The boil-off gas reliquefaction system includes: a compressor compressing boil-off gas generated from liquefied gas stored in an on-board storage tank; a heat exchanger cooling the boil-off gas compressed in the compressor; a refrigerant circulation line in which a refrigerant supplied to the heat exchanger circulates; a temperature raising line extending from the storage tank to the compressor; and a heater provided to the temperature raising line, wherein the heater heats the boil-off gas to a suitable input temperature of the compressor.
