ConRo vessel for Crowley launched at VT Halter

Pascagoula, Miss.-based VT Halter Marine recently launched the first of two new 740'x105'x59' Commitment-class combination container/roll on-roll off (ConRo) ships for Crowley Maritime Corp., Jacksonville, Fla. The El Coquí and its sistership Taíno will be fueled by liquefied natural gas (LNG).

Each of the ships will be powered by a single MAN 8S70ME-GI marine engine, producing 26,160 kW (35,054 hp) at 91 rpm. Running speed will be 22 knots. Fueling the ships with LNG will reduce emissions significantly, including a 100% reduction in sulphur oxide (SOx) and particulate matter (PM); a 92% cut in nitrogen oxide (NOx); and carbon dioxide (CO2) emissions will be cut by more than 35% per container, compared with current fossil fuels, Crowley officials said.

El Coquí and Taíno will be able to transport up to 2,400 20-foot-equivalent container units (TEUs) and a mix of nearly 400 cars and larger vehicles in the enclosed, ventilated and weather-tight ro/ro decks. The range of container sizes and types the ships can accommodate rang from 20' standard, to 53'x102", high-capacity units, as well as up to 300 refrigerated containers.

Construction of both El Coquí and Taíno is being managed in the shipyard by Crowley Marine Solutions, which includes its naval architecture and marine engineering subsidiary Jensen MaritimeEl Coquí will undergo final topside construction and testing phase before beginning service in the U.S. Jones Act trade during the second half of this year.
