A liquified gas 💧 is the liquid form of a substance which, at ambient temperature and at atmospheric pressure, would be a gas 💭.

The most important of a liquefied gas 💧, in relation to pumping and storage, is its saturated vapour pressure 📈. This is the absolute pressure exerted when the liquid is in equilibrium with its own vapour at a given temperature.

The Gas Carrier Codes relates saturated vapour pressure to temperature 🌕 and has adopted the following definition the liquified gases carried by sea :

👉 Liquids with a vapour pressure exceeding 2.8 bar absolute at a temperature of 37.8°C".

An alternative way of describing a liquified gas 💧 is to give the temperature at which the saturated vapour pressure is equal to atmospheric pressure - in other words the liquid's atmospheric boiling point.

Australia’s energy giant Woodside has completed the sale of an interest 🤝 in its liquefied natural gas (LNG) development in Calcasieu Parish, Louisiana 🏭, to Stonepeak, a New York-based investment firm specializing in infrastructure and real assets.

Cheniere Energy has taken a final investment decision (FID) on planned expansion at its Corpus Christi LNG plant and expects to grow the company’s combined production capacity to more than 60 mtpa 📈.

The US producer said it has given engineer Bechtel Energy notice to proceed with the construction of its two midscale Trains 8 and 9, which will have a combined capacity of more than 3 mtpa 💧.

QatarEnergy has paused all channel navigation from 6pm to 5am 🚨 for tankers and gas carriers in the approaches to the major export hub of Mesaieed 📌.

This is because of safety concerns that have arisen from widespread jamming of GPS signals in the region 🛰.

Coastal Bend LNG has unveiled plans to build a 22.5-mpta LNG production and export facility on the Texas coast 🏭.

The plant will comprise up to five 5️⃣ liquefaction trains of 4.5 mtpa each. 

It will also have provision for cogeneration, LNG storage tanks, and export facilities for shipping, bunkering and ISO containers 💧.

LNG Canada has successfully loaded a first cargo of liquefied natural gas 🥇 that is now destined for global markets, marking the start of operations at Canada’s first large-scale LNG export facility 🌏. 

The new LNG Canada export facility is located in Kitimat, British Columbia 🏗, in the traditional territory of the Haisla Nation. It is a long-life asset that will initially export LNG from two processing units or “trains” with a total capacity of 14 million tonnes per annum (mtpa) 💧.

The 174,000 m3 TFDE GasLog Glasgow (Built 2016) lifted this first cargo and heading now to Incheon South Korea, ETA 20th July 2025 📌.

Sanctioned LNG carrier Iris (ex-North Sky) passed through the Kara Gate entering Russia’s Northern Sea Route on June 24, likely heading for the Arctic LNG 2 plant 🏭. The move comes after the vessel spent months in ballast idling in the Barents Sea 📌.

For much of the past nine months a dozen sanctioned LNG carriers have remained largely idle 📉 and scattered across the Barents Sea on the European side and the Sea of Japan in the Far East, waiting for Arctic sea ice to recede.

The first Russian-built ice-class tanker for liquefied natural gas 🥇 is expected to go into operation in the second half of this year at the Arctic LNG 2 plant 🏭.

The tanker, named Alexey Kosygin after a Soviet statesman, was built at the Zvezda shipyard 🏗.

The tanker, already under U.S. sanctions 🚨, started sea trials at the end of last year and the final trial stage is due to begin at the end of this month.

Gaztransport & Technigaz (GTT) and China’s Hudong-Zhonghua Shipbuilding have initiated a joint innovation project 🤝 to optimize the design and performance of LNG bunkering vessels 💧.

The partners intend to increase the effective pressure in LNG tanks to 1 bar gauge (barg) 📈 from the current industry standard of 0.7 barg using GTT’s Mark III Flex membrane containment system and leveraging previous approvals from class societies for this pressure 🎯.

GTT stated that this partnership will also evaluate the technical feasibility of increasing the design pressure to 2 barg 📈.

Japanese shipping company Kawasaki Kisen Kaisha (K Line) has begun using bio-LNG to power its vessels 🔥 as part of a wider strategy to embrace renewable fuels and achieve net-zero greenhouse gas (GHG) emissions by 2050 🌎.
