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.

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.

Wärtsilä announced it is teaming up with Elliott Bay Design Group (EBDG) to advance EBDG’s Clean Harbor Alternative Mobile Power (CHAMP) Barge design.This partnership introduces a cost-effective solution to reduce emissions from large vessels in situations where traditional shore power is not available and features Wärtsilä's dual fuel methanol engine technology, the partners said.The floating mobile platform offers a power range of 6 to 16 Megawatts, utilizing green methanol as its source.

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.

Swiss marine power company WinGD has signed a memorandum of understanding with KSS Line to explore X-DF-A engines for future newbuild projects. The companies will focus on 52cm- and 62cm-bore versions of the dual-fuel ammonia engines, suitable for midsize and very large gas carriers (VLGC). The scope of the cooperation will extend beyond engine technology, also focusing on the performance and maintenance solutions necessary for using alternative fuel. The partners will also explore…

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.

BW LPG has demonstrated the value of dual-fuel LPG operations beyond the company’s initial aim of meeting IMO 2020 Sulphur Cap regulations.In October 2020, the LPG carrier BW Gemini became the first very large gas carrier (VLGC) to have its low-speed main engine converted to an LPG dual-fuel engine. The project started several years earlier, sparked by Oslo-listed BW LPG’s preparations for the IMO’s 2020 Sulphur Cap regulations.Compared to heavy fuel oil, LPG reduces Sox emissions by approximately 97%…

The Norwegian government is providing financial support for the construction of three cargo ships that will run emissions-free along the Norwegian coast.Enova, a Norwegian government enterprise promoting the use of clean energy, said it is providing NOK 130 million to Skarv Shipping Solutions AS for the acquisition of three cargo ships that will run on batteries, ammonia engines, rotor sails and energy-saving hull design. The vessels will potentially have a 90% reduction in emissions compared to similar traditional ships."Enova supports those who go ahead.

United Arab Emirates' ADNOC Logistics & Services (ADNOC L&S) has expanded its fleet with the deployment of five new-build Very Large Gas Carriers (VLGC), state news agency WAM reported on Thursday.The carriers of the shipping and maritime logistics arm of state oil giant Abu Dhabi National Oil Company each have a capacity of 86,000 cubic metres. The carriers were built at Jiangnan Shipyard in Shanghai, China, and will be owned and operated by AW Shipping, an ADNOC L&S joint venture with Wanhua Chemical Group (Wanhua), WAM added.

Jennifer Carpenter has been president and CEO of The American Waterways Operators (AWO) in January 2020, but her time with the national trade association representing the inland and coastal tugboat, towboat and barge industry dates back to 1990.

Carisbrooke Shipping Ltd have partnered with CARNOT whose consortium has been awarded £2.3 million to develop a zero-emission 50kW hydrogen auxiliary engine demonstrator under Innovate UK Clean Maritime Demonstration Competition.Following design, simulations and testing, the single-fuel hydrogen 50kW engine will be integrated into a containerized system and mounted on the deck of one of Carisbrooke Shipping's cargo vessels, Karen C, for a 40-day sea trial in early 2025 to partially supply electrical power to the vessel.The core goal is to validate the decarbonizing impact that high efficiency, zero-emission engines can have in the maritime industry and build on work from the previously successful CMDC 1 & 2 grants…

Americans became aware of our nation’s supply chain problem when they witnessed a hundred cargo ships anchored off the ports of Long Beach and Los Angeles, stymied from moving cargo to store shelves throughout the United States. Such circumstances could become all too common, especially as recently adopted engine emission regulations force maritime companies out of the country’s most impacted ports, or limit their ability to expand operations as America’s demand for imports and…

WinGD and Hyundai Heavy Industries’ Engine Machinery Division (EMD) are working together to deliver the first WinGD engine capable of running on ammonia, as the shipping industry continues to progress toward decarbonization.Under an memorandum of understanding (MOU) signed during the Posidonia exhibition on June 7, the partners will aim to deliver a first engine by 2025, in line with WinGD’s previously announced timeframe for bringing ammonia engines to market.
