The construction of a liquefied natural gas (LNG) tanker requires careful consideration of several factors to ensure safe and efficient operation. One critical aspect is the choice of materials used in its build, as well as the design itself.

A steel double hull structure is commonly employed for LNG tankers due to its numerous benefits. Firstly, it provides additional strength and stability to the vessel's frame, which is crucial given that these ships will often traverse rough seas carrying highly flammable cargo. The extra layer of protection also offers peace of mind in eventuality, should an incident occur.

In addition to safety considerations, a double hull design allows for adequate water-ballast space within the ship. This feature plays a vital role during loading and unloading operations as it helps maintain stability while minimizing potential damage to both the tanker itself and its cargo handling equipment ashore or alongside other vessels at anchorages worldwide where berthing may not always be available due partly because LNG tankers tend to draw quite deep draft wise compared against conventional merchant ships carrying heavier loads like crude oil cargoes etc.
