Introduction

Natural gas is an important source of energy and the trade for natural gas is carried out through specially designed ships known as, which in turn are a special type of gas carriers. Now we know that liquefied gas always has some vapour on top of it and this is known as the BOG or boil-off-gas. Since ships store cargo in large volumes in their cargo tanks the amount of are also quite substantial. Since it is essential to take care of these vapours for the safety of the ship, they need to be disposed off in some form or the other. So engineers thought they would use these vapours to supply a portion of the ship’s propulsive power which gave rise to special types of ships having dual fuel systems
