Belgian gas shipping group Exmar said on Thursday that the market for its very large and midsize gas carriers was at historically high levels in the third quarter and was expected to remain good in spite of new vessels being delivered in 2015. The group said its LNG business unit generated $8.5 million in operating profit in the third quarter, up from $7.8 million last year, while its LPG fleet saw an earnings spike to $15.6 million from $5.2 million last year mainly due to the sale of a vessel.
