The keel for the second Commitment Class liquefied natural gas (LNG)-powered, combination container – Roll-On/Roll-Off (ConRo) ship for Crowley Maritime Corp.’s liner services group was laid yesterday during a ceremony at ship-builder VT Halter Marine, Inc.’s facility in Pascagoula, Miss. The keel laying ceremony marked the next step in the construction of Crowley’s two Commitment Class ships, which will exclusively serve the U.S.-Puerto Rico trade lane.
“The keel laying marks the ceremonial beginning of the construction and formation of the backbone of a ship,” said Crowley’s Todd Busch, senior vice president and general manager, technical services. “Today’s event symbolizes how far we’ve come in delivering on our commitments to our customers in Puerto Rico. We are very excited to continue the construction process for these technically advanced ships.”
VT Halter Marine and Crowley entered into a contract for the pair of Jones Act ships in November 2013 and construction of the second ship began with steel cutting in Pascagoula on May 27, 2015. With the first section set in place, the ship will now begin to take shape as it is built around the keel.
The first ship’s keel laying took place in January 2015.
“Once again we are very proud to announce that another significant milestone has been met,” said Jack Prendergast, CEO, VT Halter Marine. “We are very pleased with the progress the team is making in the construction of this fine vessel. We are proud of our long association with Crowley and the commitments both companies are making toward the successful completion of this great project.”
The Commitment Class ships have been designed to maximize the carriage of 53-foot, 102-inch-wide containers, which offer the most cubic cargo capacity in the trade. The ships will be 219.5 meters long, 32.3 meters wide (beam), have a deep draft of 10 meters, and an approximate deadweight capacity of 26,500 metric tons. Cargo capacity will be approximately 2,400 TEUs (20-foot-equivalent-units), with additional space for nearly 400 vehicles in an enclosed Roll-on/Roll-off garage. The main propulsion and auxiliary engines will be fueled by environmentally friendly LNG. The Commitment Class, Jones Act ships will replace Crowley’s towed triple-deck barge fleet in the South Atlantic trade, which has served the trade continuously and with distinction since the early 1970s. These new ships, which will be namedEl Coquí(ko-kee) andTaíno(tahy-noh), will offer customers fast ocean transit times, while accommodating the company’s diverse equipment selection and cargo handling flexibility – benefits customers have enjoyed for more than 60 years.El CoquíandTaínoare scheduled for delivery during the second and fourth quarter 2017 respectively.
Powered by LNG, the Crowley ships will set a new standard for environmentally responsible shipping. LNG is a stable gas that is neither toxic nor corrosive and is lighter than air. It is the cleanest fossil fuel available, netting a 100-percent reduction in sulphur oxide (SOx) and particulate matter (PM), and a 92-percent reduction in nitrogen oxide (NOx). LNG also has the ability to significantly reduce carbon dioxide (CO2), a contributor to greenhouse gas emissions, as compared with conventional fossil fuels.
The ship design is provided by Wartsila Ship Design in conjunction with Crowley subsidiary Jensen Maritime, a leading Seattle-based naval architecture and marine engineering firm. Designing, building and operating LNG-powered vessels is very much in line with Crowley’s overall EcoStewardship© positioning and growth strategy. The company formed an LNG services group in 2014 to bring together the company’s extensive resources to provide LNG vessel design and construction management; transportation; product sales and distribution, and full-scale, project management solutions.
