Gas carrier vessels
What are gas carrier vessels?
Introduction
The maritime industry is constantly evolving and gas carrier vessels are a prime example of this. These vessels are used to transport liquefied natural gas (LNG) and liquefied petroleum gas (LPG) around the world, and their popularity is only increasing. In this post, we'll take a look at what gas carrier vessels are, how they're classified, and the main types of these vessels. We'll also explore the history of these ships and the challenges they face in the future.
Gas carrier vessels: an overview
What are gas carrier vessels
A gas carrier vessel is a type of ship designed to transport gases in bulk. There are three main types of gas carrier vessels: liquefied natural gas carriers (LNG), liquefied petroleum gas carriers (LPG), and compressed natural gas carriers (CNG).
LNG carriers are the largest type of gas carrier vessel, with an average capacity of around 125,000 cubic meters. LNG is transported at cryogenic temperatures (-162 degrees Celsius), and is typically used for long-distance transport of natural gas from production sites to consumption markets.
LPG carriers are smaller than LNG carriers, with an average capacity of around 70,000 cubic meters. LPG is transported at ambient temperature and pressure, and is typically used for shorter-distance transport of gases such as propane and butane from production sites to consumption markets.
CNG carriers are the smallest type of gas carrier vessel, with an average capacity of around 3,500 cubic meters. CNG is transported at high pressure (around 250 bar) and temperature (around 20 degrees Celsius), and is typically used for local distribution of natural gas within cities or regions.
How are gas carrier vessels classified
Gas carrier vessels are classified according to the type of cargo they carry: Liquefied Natural Gas Carriers (LNGCs), Liquefied Petroleum Gas Carriers (LPGCs) or Compressed Natural Gas Carriers (CNGCs). The classification society Lloyd's Register provides rules and guidance for the construction and operation of all three types of vessel.

The history of gas carrier vessels
The early days of gas carrier vessels
In the early days of gas carrier vessels, the main type of vessel used was the liquefied natural gas (LNG) carrier. These vessels carried LNG from production areas to markets. The first LNG carrier was built in 1959, and the industry has grown since then.
The development of gas carrier vessels
As the demand for natural gas grew, so did the need for larger and more sophisticated gas carriers. In the 1970s, new technologies were developed that allowed for the construction of larger vessels and the transportation of other types of gases, such as liquefied petroleum gas (LPG) and liquefied natural gas (LNG). These advances led to the development of new types of gas carriers, such as LPG carriers and LNG carriers.
The modern gas carrier vessel
Today, there are four main types ofgas carrier vessels: Liquefied Petroleum Gas Carriers (LPG), Liquefied Natural Gas Carriers (LNG), Methane Carriers (MGC) and Ethane Carriers (EGC). Each type of vessel has its own unique characteristics and is designed to carry a specific type or group of gases.
The future of gas carrier vessels
The challenges of the future
The future of gas carrier vessels is fraught with challenges. The most pressing of these is the need to reduce emissions. Gas carrier vessels are some of the most polluting ships on the planet, and their emissions contribute significantly to climate change. In addition, gas carrier vessels are also a major source of air pollution, which can have serious health impacts.
There are a number of ways to reduce emissions from gas carrier vessels. One is to use cleaner fuels. LNG is one such fuel, and it is already being used by some gas carrier vessels. Another option is to retrofit existing vessels with cleaner engines or install exhaust scrubbers. These measures can be expensive, however, and may not be feasible for all shipowners.
Another challenge facing the future of gas carrier vessels is the increasing regulation of maritime shipping. The International Maritime Organization (IMO) has set ambitious targets for reducing emissions from maritime shipping, and gas carrier vessels will need to comply with these regulations if they are to continue operating in the future. This could mean making significant changes to vessel design or operations, which could be costly for shipowners.
Finally, there is the challenge of competition from other modes of transport. Gas pipelines are increasingly being used to transport natural gas, and this could eat into the market share of gas carrier vessels in the future. It is important for shipowners to stay ahead of these trends and adapt their business models accordingly if they want to remain competitive in the years ahead.
The potential of gas carrier vessels
Despite the challenges faced by gas carrier vessels in the future, there is still considerable potential for growth in this sector. The demand for natural gas is expected to increase in the coming years as countries move away from dirtier fossil fuels such as coal and oil. This will create new opportunities for gas carriers to transport natural gas around the world.
In addition, there is growing interest in using LNG as a marine fuel due to its environmental benefits over other fuels such as heavy fuel oil (HFO). This presents an opportunity for shipowners who are able to invest in LNG-powered vessels or retrofit existing ones with LNG engines. There are also opportunities for shipowners who can provide efficient logistical solutions for transporting LNG around the world.
Conclusion
The gas carrier vessel is a key player in the global energy market, transporting natural gas around the world. These vessels come in different shapes and sizes, and are classified according to their cargo capacity and the type of gas they carry.
Despite the challenges that lie ahead, the future of gas carrier vessels looks promising. With new technologies and an ever-growing demand for natural gas, these vessels will continue to play a vital role in our economy and our way of life.
