Classification society Bureau Veritas on Monday (8 May) said it delivered an Approval in Principle (AiP) to GTT and Shanghai Waigaoqiao Shipyard (SWS) for the design of a Liquefied Natural Gas (LNG) dual-fuel Very Large Crude Carrier (VLCC).

This approval is part of a Joint Development Project (JDP) initiated in May 2022, and was successfully carried out by Shanghai Waigaiqiao Shipyard (SWS) and Bureau Veritas (BV).

The greater operational flexibility offered by this new 10,000 m3 capacity fuel tank concept, enables owners and charterers to conduct round trip voyages between the Middle East, Asia, and Europe with just one LNG bunkering operation.

The fuel tank is located below the main deck to avoid exposure to bad weather and the risk of piracy, while lowering the centre of gravity of the propulsion systems. It features Mark III membrane containment technology, developed by GTT.

In addition to its operational benefits, the new LNG dual-fuel VLCC concept complies with key environmental requirements. Its Energy Efficiency Design Index (EEDI) is more 37% under the baseline, its Nitrogen Oxides (NOX) emissions meet the IMO’s Tier III requirements, and its Carbon Intensity Index (CII) is projected to be rated A by 2030.

Adnan Ezzarhouni, General Manager of GTT China, said: “We are delighted to be granted with this AiP by Bureau Veritas with whom GTT has had a close partnership for many years. Following our successful references in LNG-fuelled container and cruise vessels, we are pleased to offer this fit-for-purpose membrane tank solution to the LNG-fuelled tanker market.”

Alex Greg-Smith, Senior Vice President Chief Executive, Marine & Offshore North Asia and China, Bureau Veritas, said: “Our knowledge of LNG as fuel was mobilised from the design phase for this dual fuel VLCC. From plan approval to classing the vessel – Bureau Veritas experts played a key role in ensuring this sophisticated tanker can take to the seas safely. Dual fuel carriers open a window into what the future of the maritime energy transition will look like. A new generation of VLCCs will contribute both to maritime decarbonization as a whole and to the reduction of scope three emissions in countless other sectors.”

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.
