The following is an article titled “Innovative viscosity meter opens the way for smarter use of fuel oil at sea” written by Ian Mundell elaborating on a viscosity metre developed in a Knowledge Transfer Partnership between Imperial and Rivertrace that will help make shipping cleaner and more efficient. Below is an excerpt of the article published on the Imperial College London website: 

An innovative device for measuring the viscosity of the fuel oil used in ship engines has been developed and commercialised thanks to a collaboration between Imperial and Rivertrace, a company specialising in instruments for the maritime industries.

The research and development was carried out under the Innovate UK Knowledge Transfer Partnership (KTP) scheme, which funds talented graduates and postgraduates while they work on innovation challenges set by companies. The challenge that Rivertrace set Dr Frederic Cegla of the Department of Mechanical Engineering was to find an effective, economic method of measuring the quality of the heavy fuel oil used in cargo ships and other large vessels.

This oil is the lowest grade of fuel produced in oil refining, and is loaded with impurities. “It’s just one step above the bitumen used to surface roads,” says Mike Coomber, Executive Chairman of Rivertrace.

The most problematic of these impurities are tiny fragments of the catalysts used in the refining process, and which are left behind in the fuel oil. These ‘cat fines’ are extremely hard and wear away the inside of a ship’s engine, increasing the risk of breakdown at sea.

In order to use this heavy fuel, it must first be heated up to around 100-150°C, so that its viscosity drops enough so that it can easily flow and can be  fed into the engines. Then it is passed through a hydrocyclone, a device that uses centrifugal force to separate out the cat fines.

“These hydrocyclones only have one mode, which is full-on,” explains Mr Coomber. “So, if you can better interrogate the quality of the heavy fuel oil, you can better control the purifiers, with a cost saving in the energy the ships have to consume to get an acceptable product to their engines.”

Being able to measure the fuel oil quality also opens up the possibility of predicting the wear and tear on the engine, allowing inspections and maintenance to be scheduled effectively.

ITOCHU orders world’s first ammonia bunkering vessel for Singapore demonstration project

ITOCHU Corporation (ITOCHU) on Monday (14 July) announced that it recently signed a shipbuilding contract for the construction of a 5,000 m3 ammonia bunkering vessel with Sasaki Shipbuilding. 

The company also announced an agreement regarding the construction of an ammonia tank plant that will be loaded onto the vessel with Izumi Steel Works. 

These agreements were signed by Clean Ammonia Bunkering Shipping Pte Ltd (CABS), a wholly owned Singapore-based specific purpose company of ITOCHU. 

In relation to this, CABS has concluded a financing agreement with The Hiroshima Bank for financing a part of purchase price of the vessel.

The agreements were concluded to pursue the Demonstration Project for Bunkering Ammonia as Marine Fuel in Singapore adopted by the Ministry of Economy, Trade and Industry in Japan as part of the Global South Future-oriented Co-Creation Project (large-scale demonstration in ASEAN member states). 

Going forward, with an eye toward the demonstration of ammonia bunkering in Singapore after building the world’s first newbuilding ammonia bunkering vessel, ITOCHU said efforts will be made to facilitate concrete discussions with the maritime stakeholders, including the port authority in Singapore, the Maritime & Port Authority of Singapore (MPA), and the fuel producers, while obtaining support from the Japanese Government.

The vessel is to be flagged under the Singapore Registry and is expected to be delivered in September 2027.

ITOCHU will establish a safe offshore bunkering operation of ammonia as marine fuel by way of ship-to-ship transfer through the development and construction of the vessel and demonstration. 

Then, by utilising the vessel, ITOCHU will establish connection between the first movers in clean ammonia production and the first movers in the ammonia-fueled vessels and secure initial demand for ammonia as marine fuel, aiming at the commercialisation of ammonia bunkering business in Singapore and expansion of similar business model to major maritime transportation points around the world, including Spain (Strait of Gibraltar), Egypt (Suez Canal) and Japan.

RESIZED bunker tanker singapore

The Maritime and Port Authority of Singapore (MPA) on Tuesday (15 July) conducted a multi-agency chemical spill exercise to strengthen Singapore’s operational readiness, as part of the International Safety@Sea (S@S) Week. 

MPA is organising the 12th edition of the S@S Week, with this year’s event being the international edition, taking place from 15 to 18 July 2025. 

Conducted off Singapore’s southern coast, the exercise involved 11 vessels and over 150 personnel from more than 10 government agencies and industry partners. Mr Murali, Mr Dominguez and Secretary-General, International Organization for Marine Aids to Navigation, Mr Francis Zachariae, observed the exercise.

The exercise simulated a methanol spill from a collision involving a methanol-carrying tanker, triggering a multi-agency response. This included coordinated efforts for spill containment and the evacuation of injured crew. A range of drone-enabled technologies was trialled during the exercise, including 3D imaging to assess vessel damage and a water curtain misting system to limit the spread of chemical plumes. An Uncrewed Surface Vehicle was also deployed to monitor air quality, reducing the need for responders to enter hazardous zones to perform such monitoring. The Maritime Digital Twin and chemical plume modelling tools were used to enhance situational awareness and support decision-making throughout the exercise.

The exercise is part of MPA’s broader preparations for methanol bunkering and provided a valuable opportunity for agencies and industry partners to better understand the safety and operational challenges, and potential solutions, in handling alternative fuels. Following an open call in March 2025, MPA has received 13 applications for methanol bunker supplier licenses, reflecting strong industry interest in supplying methanol on a commercial scale in Singapore. MPA is evaluating the applications and targets to issue the licenses in Q4 2025, which will cover the period from 1 January 2026 to 31 December 2030. 

Themed ‘The Future of Maritime Safety: Navigating the Next Frontier’, the annual event brings together local and international maritime experts, and the maritime community to promote awareness and facilitate discussions on maritime safety. 

Speaking at the opening today, Mr Murali Pillai, Senior Minister of State, Ministry of Law and Ministry of Transport, said that the maritime sector is facing increasingly complex global challenges, including heightened geopolitical tensions, climate change, and rapid transformation in digitalisation and decarbonisation. He highlighted that we can tackle these challenges by (i) equipping our workforce for future challenges, (ii) harnessing collective expertise through close collaborations and partnerships, and (iii) drawing upon technology and innovation to augment our capabilities. 

In his keynote address, Mr Arsenio Dominguez, Secretary-General of the International Maritime Organization (IMO), underscored the need for robust safety frameworks and regulations as the maritime landscape evolves. He cited Maritime Autonomous Surface Ships and new ship designs and systems using sustainable marine fuels as examples of how the maritime sector is transforming and outlined IMO’s priorities in those areas. Mr Dominguez also highlighted the importance of government-industry collaboration and initiatives like the Safety@Sea Singapore Campaign to foster a safety-first culture at sea.  

This year’s conference features 19 speakers across three plenaries. Discussions will focus on issues shaping the future of maritime safety, including lessons learned from past incidents, and the human element in ensuring safety as the industry transforms. A new Safety@Sea Community Conversations event will also bring together representatives from shipping companies, regional ferry operators, harbour craft operators and terminal operators to share their experiences and efforts in fostering a safety culture in their organisations. 

Over 1,800 participants from more than 40 countries are expected to participate in the week’s sessions. Other highlights include the Responders Plus Programme (RPP) Maritime Workshop jointly organised by MPA and the Singapore Civil Defence Force, and two safety forums organised by the MPA-Harbour Craft and MPA-Pleasure Craft Safety Work Groups to promote safety awareness and best practices within the local maritime community. 

MPA is also enhancing safety across other areas of port operations. In collaboration with Skyports Drone Services, TFG Marine and CBS Ventures, MPA and the partners will complete Singapore’s first shore-to-ship drone trials for delivery and retrieval operations from bunker tankers later this week. 

The use of drones reduces reliance on harbour craft for such operations, improving efficiency while reducing pollution and congestion. 

It also minimises safety risks by removing the need for crew to handle and transfer heavy items between the ship and shore using harbour craft. Safety considerations, including the management of electrostatic discharge risks during the drone operations, are carefully reviewed in preparation for the trials. 

Findings from these trials will inform the development of safety protocols and an operational framework to support the phased implementation of this new maritime service.
