Crowley and VT Halter Marine launched Crowley's new Commitment-class ship El Coquí, one of the world's first combination container/Roll on-Roll off (ConRo) ships powered by liquefied natural gas in Pascagoula. El Coquí, named after a "beloved" frog native to the island, will now proceed through the final topside construction and testing phase before beginning service in the US Jones Act trade during the second half of 2017.
