US Maritime Administrator Mark Buzby sees the growth in LNG as an opportunity for US shipyards.

Testifying before the House Committee on Transportation and Infrastructure Wednesday, Buzby blamed the struggles of domestic shipbuilders on subsidized foreign competition. But LNG, he said, could be a means for a turnaround.

"The global LNG market ... is anticipated to expand over the next 20 years and it is estimated that the number of LNG ships necessary to service the market will nearly double by 2040," Buzby told the assembled representatives.
