The order includes options for an additional two vessels.Each…

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.

Seakeeper has launched two new gyrostabilizer models the Seakeeper 10.5 and the Seakeeper 14, designed for vessels ranging from 50 feet to 68 feet long.The Seakeeper 10.5, engineered for boats 50-62 feet, evolved from its two predecessors, the Seakeeper 9 and the inaugural M7000 and offers 17% more angular momentum in 23% less volume.The Seakeeper 14, suited for boats 55-68 feet, bridges a gap in the current lineup between the Seakeeper 9 and the Seakeeper 18. The new model is is 43% smaller and 33% lighter than the Seakeeper 18.

MAN Energy Solutions has won the contract from Royal Boskalis to supply 3 × MAN 49/60 engines for a 31,000 m³ Trailing Suction Hopper Dredger (TSHD).Each engine will come accompanied by an exhaust-gas after-treatment system, namely an MAN Low-Pressure Selective Catalytic Reduction (LP-SCR) system, that ensures IMO Tier III compliance.

A collaboration between Oak Ridge National Laboratory (ORNL) and Caterpillar Inc. will investigate using methanol as an alternative fuel source for marine vessels.Members of the research team kicked off the project with the installation of a 6-cylinder engine at the Department of Energy’s National Transportation Research Center at ORNL.The ORNL and Caterpillar collaboration focuses on a four-stroke internal combustion marine engine that will be modified to run on methanol.Although methanol has many advantages, it is more difficult to ignite than diesel.

Fuel flexibility may be a key driver for recent developments in gensets, but the perennial goals of lowering CapEx and OpEx remain.Fuel flexibility is one of the pillars of decarbonization that is being embraced by genset OEMs. Fuel efficiency, a second pillar, goes hand in hand with that because new fuels will be more expensive, but these concerns come in addition to the on-going drive to reduce CapEx and OpEx for shipowners.MAN Energy Solutions introduced its auxiliary MAN 35/44DF CD engine in June 2023. It is designed to be future-proof and will be ready for methanol operation by 2026.

A maintenance error caused an engine room fire aboard the Endo Breeze last year, resulting in $1.2 million in damages, a National Transportation Safety Board (NTSB) analysis has shown.On April 29, 2022, the Endo Breeze was transiting outbound through the Raritan Bay West Reach channel near Staten Island, New York, when oil spray from a fuel injector pump on the starboard main engine ignited off nearby hot surfaces, causing a fire. The crew of the Endo Breeze contained the spread of the fire by removing fuel and oxygen sources…
