The main attempt of this study is to overview and to discuss occupational safety and environmental conciseness for the transportation of LNG with gas carriers. LNG is transported by a fleet of 157 LNG tankers of varying sizes from 18,500 m3 to 140,000 m3. This study investigates the technological development and innovation in LNG transportation while considering safety and environmental standards and regulations for LNG shipping. It is also originally contributing the process safety for decision making process for the MET institutions while planning the further needs of LNG industry during the planning of their related curricula. The further research activities could also be concentrated on quantitative risk evaluations of LNG equipment, based on risk maintenance and reliability concepts.
