Technology group Wärtsilä on Tuesday (20 December) said it will supply its hybrid propulsion system with methanol engine for four new heavy lift vessels being built at the Wuhu Shipyard in China.

Wärtsilä’s innovative hybrid system will minimise the ships’ CO2 emissions, thus supporting the marine sector’s decarbonisation ambitions. The system will feature a variable-speed Wärtsilä 32 main engine capable of operating with methanol bunker fuel.

The vessels have been contracted by SAL Heavy Lift GmbH, a German heavy lift and project cargo specialist and part of the Harren Group, in cooperation with its joint-venture partner, Netherlands-based Jumbo Shipping. There is an option for an additional two vessels. The order was included in Wärtsilä’s order book in December 2022.

This will therefore make these ships among the first to be prepared to operate on methanol, a clean burning sulphur-free alternative to conventional fossil-based marine fuels. They will also be the first methanol capable ships to employ a variable speed main engine.

The hybrid system also includes Energy Storage, a PTO/PTI generator and motor, a multidrive converter, and the Wärtsilä Energy Management System for controlling and optimising the hybrid operations. The Energy Storage system will be based on Lithium-Titanium-Oxide (LTO) batteries, which can handle higher amounts of deep cycles than normal Lithium-Ion based systems. The ESS will significantly reduce the fuel consumption and/or the necessary size of the port’s electric shore connection during crane operations while also providing fuel savings at sea by reducing Engine Load fluctuations in rough seas.

For each vessel, Wärtsilä will also supply the gearbox, the controllable pitch propeller (CPP), the bow and stern thrusters, air shaft seals, as well as the sterntube and bearings.

“These ships represent the next generation in heavy lift shipping. In addition to their technical capabilities, they will feature outstanding environmental performance and help guide shipping towards a greener future,” says Dr Martin Harren, Owner and CEO of SAL Heavy Lift. “We are committed to decarbonising shipping activities, and we wish to thank Wärtsilä for their support and cooperation throughout this project.”

“We are proud to be able to support SAL with Wärtsilä’s market-leading integrated hybrid-mechanical propulsion system. This is a well-proven, future-proofing solution that enables owners and operators to lower operating costs while complying with current and anticipated environmental regulations,” says Matthias Becker, Managing Director of Wärtsilä Germany.

The ships are scheduled for delivery in 2025 and will be used mainly to support wind farm installations.

Wärtsilä is a market leader in hybrid solutions for shipping applications with installations on board more than 70 vessels, and an installed battery capacity in excess of 100 MWh. The company has a broad portfolio of fuel-flexible marine engines that offer sustainable alternatives as the industry journeys towards a decarbonised future.

Singapore: Bunker fuel sales down by 3.8% on year in July 2026

Sales of marine fuel at Singapore port fell by 3.8% on year in July 2026, according to data from the Maritime and Port Authority of Singapore (MPA).

In total, 4.73 million metric tonnes (mt) (exact 4,731,900 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in July, up from 4.92 million mt (4,918,000 mt) recorded during the similar month in 2025.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in July (against on year) recorded respectively 1.95 million mt (zero from 1.95 million mt), 2.33 million mt (-2.1% from 2.38 million mt), 1,600 mt (+100% from zero), 700 mt (-82% from 3,900 mt) and zero (from zero).

Bio-blended variants of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in July, (against on year) recorded respectively 8,200 mt (-83.7% from 50,300 mt), 29,900 mt (-62.9% from 80,500 mt), zero (from zero), zero (from zero) and zero (from zero). B100 biofuel bunkers, introduced in February last year, recorded 1,400 mt (-46.2% from 2,600 mt).

LNG and methanol sales were 58,700 mt (+41.4% from 41,500 mt) and zero (from zero) respectively. There were no recorded sales of ammonia for the month and so far since 2025.

The Maritime and Port Authority of Singapore (MPA), together with industry partners, on Monday (17 August) launched several new initiatives to enhance maritime safety.

Announced at the opening of the 13th Singapore Safety@Sea Week, these initiatives will support shared learning, strengthen operational capabilities, and prepare the industry for the safe adoption of new technologies.

Organised by MPA from 17 to 21 August, this year’s Safety@Sea Week is themed “All Hands on Deck – Safety First!”. About 1,500 participants from across the maritime community are expected to take part in 18 events organised by MPA and its partners.

These include the Safety@Sea Symposium, featuring seven speakers across two panel sessions, and three workshops on ammonia bunkering, methanol bunkering, and crew safety awareness.

Speaking at the opening, Mr Murali Pillai, Senior Minister of State for Law and Transport, highlighted three priorities for strengthening maritime safety: harnessing technology responsibly, preparing early for emerging risks, and keeping people at the centre of safety. He also underscored the importance of strong partnerships across the maritime community in building a strong safety culture.

At the opening of Safety@Sea Week, the National Maritime Safety at Sea Council and the Singapore Shipping Association launched the Singapore Near Miss Reporting System to encourage the reporting and sharing of lessons from near miss incidents.

Modelled on the internationally recognised Confidential Human Factors Incident Reporting Programme (CHIRP), the system provides sea space users with a confidential online channel to report near misses. CHIRP will independently receive the submissions and provide anonymised information to the Council, which will distil key safety lessons for sharing with the wider maritime community.

Shanghai port completes first simultaneous two-vessel, two-fuel green bunkering operation

SIPG Energy (Shanghai) Co Ltd (SIPG Energy) on Sunday (16 August) completed what it described as China’s first simultaneous two-vessel bunkering operation involving two different green marine fuels at anchorage, supplying LNG and bio-methanol to two vessels.

The company’s LNG bunkering vessel Hai Gang Wei Lai supplied LNG to PIL’s KOTA ELAN, while methanol bunkering vessel Hai Gang Zhi Yuan supplied domestically produced biomass-based methanol to CMA CGM’s dual-fuel container ship CMA CGM OSMIUM.

According to SIPG Energy, the two bunkering operations were carried out simultaneously and safely, highlighting Shanghai Port’s growing ability to provide diversified and large-scale green-fuel bunkering services at anchorage.

The operation required enhanced coordination in safety management, resource allocation and emergency response. Shanghai Maritime Safety Administration, Shanghai Customs and Shanghai General Station of Immigration Inspection, along with other supporting organisations, provided regulatory guidance and operational support.

“The combined efforts of all parties significantly improved the efficiency of bunkering at anchorage,” the company said.

The company said it will continue to expand its safe bunkering capabilities for bio-methanol, LNG and other green marine fuels, while broadening its fuel supply portfolio and service scenarios to support the shipping industry’s transition to lower-carbon marine fuels.
