US ship operator Crowley Maritime Corporation has, according to MAN Diesel & Turbo, placed an order for two con-ro vessels with dual-fuel main and auxiliary engines.

Each of the two 26,500dwt ships, described as a combination of lift-on-lift-off container and ro-ro cargo vessel technology, will have an 8S70ME-GI8.2 main engine and three 9L28/32DF auxiliaries. They are to be built at VT Halter Marine and are scheduled for delivery in the second and fourth quarters of 2017.

The vessels will be 219.5m long, and named El Coquí and Taíno. MAN says that they will be two of the first LNG-powered con-ro ships. They are designed to travel at speeds up to 22 knots, and carry around 2,400teu made up of various sized containers, along with space for almost 400 vehicles in the enclosed, weather-tight cargo hold.

Tom Crowley, company chairman and CEO, said: “Our investment in these new ships – the first of their kind in the world – is significant” He continued: “[W]e are developing and using best-available technology that allows for improved emissions and alternative fuel selection”.

According to MAN, Crowley selected its high-pressure, Diesel-cycle ME-GI engines due to their high efficiency and power concentration, the ability to avoid derating, and negligible methane slip.

The pair will be classed by DNV to Clean notation, and Crowley expects to reduce the amount of CO2 emissions attributable to each container by around 38%.
