LNG is brought onto the vessel and taken along the spray line to the main vaporiser, which boils off the liquid into gas. This is then warmed up to roughly 20 °C (68 °F) in the gas heaters and then blown into the tanks to displace the "inert gas". This continues until all the CO 2 is removed from the tanks. Initially, the IG (inert gas) is ...
The International Safety Guide for Oil Tankers and Terminals (often shortened to ISGOTT) is a standard code of practice for the safe operation of Oil tankers and Oil terminals. [1] Published by Witherbys, it is a joint publication produced by the International Chamber of Shipping (ICS), the Oil Companies International Marine Forum (OCIMF), and ...
The IGF Code provides industry standards for ships that use fuels with a flashpoint of less than 60°C. The IGF Code seeks to regulate the safety changes from the carriage and use of gas fuel, in particular liquefied natural gas and other low-flashpoint fuels. These fuels are used in engines such as a Marine LNG Engine.
The Code also sets out requirements for emergency shutdown (ESD) systems for when liquefied gas cargoes are carried in bulk. [4] Section 4.1 of the IGC Code defines several types of tanks that can carry liquefied gases. These include independent tanks (of which there are three types, A, B and C), membrane tanks, integral tanks and semi-membrane ...
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Water storage tank. Hot water to domestic appliances. A small tank water heater. Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.
A liquefied natural gas terminal is a facility for managing the import and/or export of liquefied natural gas (LNG). It comprises equipment for loading and unloading of LNG cargo to/from ocean-going tankers, for transfer across the site, liquefaction, re-gasification, processing, storage, pumping, compression, and metering of LNG.

The tugboats Reid McAllister and McAllister Responder push the LPG tanker BW Volans into port at Marcus Hook, on the Delaware River. A gas carrier, gas tanker, LPG carrier, or LPG tanker is a ship designed to transport LPG, LNG, CNG, or liquefied chemical gases in bulk. [1]
