Hartmann said it has worked in cooperation with Hunte Engineering on the 36,000-cbm ships, which were contracted at Sinopacific Offshore & Engineering at around $81m each, to produce a new type of gas carrier.

The company said the vessels, which it has named Eco Star 36k, are currently the largest LEG carriers on order.

They are scheduled for delivery from the second half of 2016 onwards.
