World's Largest Cruise Ship Sets Sail, Bringing Concerns About Methane Emissions

The world's largest cruise ship is set for its maiden voyage on Saturday, but environmental groups are concerned that the liquefied natural gas-powered vessel - and other giant cruise liners to follow - will leak harmful methane into the atmosphere.Royal Caribbean International's Icon of the Seas sets sail from Miami with capacity for 8,000 passengers across 20 decks, taking advantage of the surging popularity of cruises.The ship is built to run on liquefied natural gas (LNG), which burns more cleanly than traditional marine fuel but poses greater risks for methane emissions.

Naftomar Shipping Orders Four Ammonia-powered VLGCs

Shipowner Naftomar Shipping announced an order for four very large ammonia carriers, to be built by South Korean shipbuilder Hanwha Ocean (formerly known as Daewoo Shipbuilding & Marine Engineering) for scheduled delivery from 2026. With a capacity of 93,000 m3, the ships are among the world’s largest ammonia carriers ordered to date.The Bureau Veritas (BV) classed ships will be fitted with a ME-LGIP LPG dual-fuel engine, ready to be converted to use ammonia as fuel when the MAN ES ammonia engine retrofit kit is made available.

Maritime Propulsion: The NSMV Power Play

The quest to build a series of five National Security Multi-Mission Vessels (NSMVs), which will serve as training ships for five U.S. maritime academies, has drawn a broad cadre of suppliers. The powerplant was a main focus, helping to evolve the schools from steam power plants to a modern propulsion package.NSMVs being built for the maritime academies is widely lauded as a ‘win’ for U.S. shipbuilding, an example of commercial shipbuilding practices applied to a government shipbuilding project.

Furetank and Wärtsilä Advance Engine Technology to Reduce Methane Slip

Wärtsilä and Swedish shipping company Furetank are co-developing and testing two technologies showing the potential to halve the methane slip.Running vessels on LNG or bio-LNG reduces emissions of CO2, NOx, SOx and harmful particles, but the downside is methane slip: the release of unburned gas fuel, not fully combusted in the engines.Although the fraction released is small, methane is a more potent greenhouse gas than CO2.Two technical solutions have been tested in Furetank’s Vinga series tankers.

WinGD Enhances Fuel-Flexible Efficiency with Variable Compression Ratio

Swiss marine power company WinGD has introduced a core engine technology that eliminates the need for ship operators to compromise on optimal combustion when using multiple fuels.Variable Compression Ratio (VCR), jointly developed with Mitsui E&S DU Co (MESDU), will be installed on a vessel powered by an X62DF engine and then rolled out across selected engines of the X-DF engine portfolio.An engine’s compression ratio is usually a fixed parameter, playing a direct role in power and fuel efficiency.
