Very Large Gas Carriers (denoted as VLGC vessels) are a sub-class of generic gas carriers that target a considerably higher volume of gas transport. In general, the most common gas that is shipped is liquified petroleum gas (LPG) that is extracted from petroleum reserves.
liquified natural gas (LNG) that is extracted from hydrocarbon deposits near fossil fuels.The VLG Carriers are capable of loading anywhere between a lakh cubic meters to two lakh cubic meters of gas into large tanks.
These tanks are built under the deck and regulate gas loading and unloading using a system of pumps and valves. In this article, we will take a look at the construction, design and layout of a classic VLGC vessel.
While solids can easily be moved using cranes, liquids and gases must be drained completely at the port of unloading. Any residual substances can pollute or contaminate any incoming cargo. The VLGC designs feature double bottom structure and an additional side shell in certain carriers.
The purpose behind having multiple hulls is that it is possible to contain a leak, while also providing room for the vital components of the ship. Most of the electrical wiring and pipes required for the operation of the ship runs within this shell. Often, the double bottom also has a ducted keel that allows main connections and wires to run along the entire length of the ship unobstructed.
The Global Very Large Gas Carrier Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
NYK is delighted to announce the order of its fifth liquefied petroleum gas (LPG) dual-fuel very large LPG / liquefied ammonia gas carrier (VLGC) from Kawasaki Heavy Industries Ltd. (KHI). The ship will be built at the KHI Sakaide Works shipyard and is set for delivery in 2026.
This vessel is the seventh in NYK’s fleet of LPG-fueled LPG carriers and the fifth in a new type of vessel that is also capable of carrying ammonia and will be equipped with separate cargo tanks designed to carry LPG and ammonia at the same time to flexibly respond to various trade patterns.
