The Conch 165,000m3 LNG Tanker (Downloadable Product)
At the time this paper was prepared, it was believed that there were several reasons for supposing that larger LNG tankers would soon be ordered, ie:
- the total capital investment required for a given project would be reduced
- the overall fleet operating costs would be less
- operating experience on the existing 75 000 cu m ships was accumulating rapidly and the first 125 000 cu m ships were entering service.

As we now know it took a further 35 years before LNG carriers of 165,000 cu m 9and larger arrived) but this paper shows how owners and builders in the mid '70's felt relaxed about the step up in size. (13pp)
