Technology group Wärtsilä will deliver its first ever Wärtsilä 31 engine retrofit to Gardar, a fishing vessel owned by Norwegian Gardar AS, built originally in 1998.

After the retrofit is completed, Gardar’s fuel consumption will be reduced by 200,000 litres and NOx emissions by over 88 tonnes annually.

The decision to retrofit Gardar’s engine will have a huge impact on the vessel’s environmental footprint. Lower fuel costs and NOx fees, combined with the longer service interval of the Wärtsilä 31 engine, will result in significantly lower operating costs.

The existing 18-cylinder Wärtsilä 32 engine in V-configuration will be replaced with the 10-cylinder Wärtsilä 31 engine in V-configuration.

Wärtsilä 31 engine holds the Guinness World Record as the most effective medium-speed diesel engine in the world. In addition, the vessel will be installed with Wärtsilä NOx Reducer emission after-treatment system with a compact silencer. The propulsion control system will also be upgraded.

Norwegian NOx Fund has committed a substantial amount of support for this project, resulting in a very satisfactory repayment period.

“We are extremely happy to be able to make Gardar more ecologically sound. The investment in retrofitting the vessel will quickly pay itself back in terms of reduced fuel costs and NOx fees. We have been very satisfied with Wärtsilä’s engines and propulsions and consider installing the NOx reducers to two more of our vessels,” says Christian Halstensen, owner and manager of Gardar AS.

“We could not be prouder of this agreement, as it shows responsibility from the customer and gives us the opportunity to contribute to more environmentally sound shipping. At Wärtsilä, we understand that a project like this is an investment financially, but it is also an investment in our future. We warmly support every action that goes beyond just meeting the environmental regulations,” says Cato Esperø, Sales Director, Wärtsilä Services.

Study finds OCCS could reduce up to 20% CO2 emissions on “Stena Impero”

Engineering project found that the technology could reduce the vessel’s carbon dioxide (CO2) emissions by as much as 20% per year, with a fuel consumption penalty of just under 10%.

Study finds OCCS could reduce up to 20% CO2 emissions on “Stena Impero”

A project assessing the technical feasibility of onboard carbon capture and storage (OCCS) in the shipping sector has concluded that the technology has the potential to help maritime transport significantly reduce its greenhouse gas emissions, according to a joint statement on Thursday (10 October).

The engineering project analysed the design and cost implications of retrofitting a carbon capture system on the medium-range tanker Stena Impero. It found that the technology could reduce the vessel's carbon dioxide (CO2) emissions by as much as 20% per year, with a fuel consumption penalty of just under 10%.

The project was carried out by the Oil and Gas Climate Initiative (OGCI), the Global Centre for Maritime Decarbonisation (GCMD) and Stena Bulk together with a consortium of maritime organisations.

The project, Realising Maritime Carbon Capture to Demonstrate the Ability to Lower Emissions, (REMARCCABLE) was supported by a consortium comprising American Bureau of Shipping, Alfa Laval, Deltamarin, Lloyd's Register, Seatrium, and TNO. It aimed to assess the viability of deploying carbon capture systems on vessels with minimal impact on operational constraints.

The cost of building and installing the full system on the Stena Impero is estimated at USD13.6 million, with an abatement cost of avoided CO2 for the first-of-a-kind prototype evaluated at USD 769/tonne CO2.

However, the consortium believes that further research and development will drive down costs, making OCCS increasingly viable for the shipping industry.

The study also looked at incorporating OCCS on newbuild vessels, with the findings that improvements to capture rate and fuel penalty may be achieved using more efficient engines, heat pumps, and alternative solvents.

Professor Lynn Loo, CEO of GCMD, said: “OCCS has gained traction in recent years as a feasible approach to meet the 2023 IMO revised GHG emissions reduction targets. However, its adoption faces numerous hurdles, including the need to balance the tension between maximising CO2 capture rates while maintaining commercially acceptable CapEx and OpEx. This study provides quantitative insights on managing the trade-offs between the actual cost of operating OCCS and its emissions reductions potential.

“For OCCS systems to be practical, the industry needs to manage captured CO2 effectively. To this end, GCMD has previously completed a study to define the operational envelope for offloading onboard captured CO2, contributing to the whole-of-system approach to emissions reduction via carbon capture.”

SIBCON 2024: New Singapore standard on digital bunkering to be launched

Enterprise Singapore (EnterpriseSG), through the Singapore Standards Council (SSC), will launch a new Singapore Standard (SS) 709 Specification for Digital Bunkering Supply Chain Documentation, according to Maritime and Port Authority of Singapore (MPA) on Wednesday (9 October).

MPA said the new standard will ensure data consistency and interoperability between digital systems and facilitate smoother transactions through trusted and verifiable digital bunkering documents.

This comes following Amy Khor, Senior Minister of State for the Ministry of Sustainability and the Environment and the Ministry of Transport, announcing that from 1 April 2025, all bunker suppliers will be required to provide digital bunkering services and issue electronic bunker delivery notes (e-BDNs) as a default.

The move was decided following successful pilots conducted since 1 November 2023 with bunker suppliers, including the top 10 bunker players, in Singapore.

To further enhance transparency and transaction integrity in bunkering operations, MPA will also introduce a centralised e-BDN record verification facility. This enables key stakeholders to verify the e-BDN received against the information transmitted to MPA.

EnterpriseSG has also launched the revised Singapore Standard (SS) 648 Code of Practice for Bunker Mass Flow Metering to include data integrity and transmission requirements in line with this new digital standard.

In the first eight months of 2024, MPA said Singapore saw strong growth of approximately 7% in total bunker sales over the same period last year, reaching over 36 million tonnes. Biofuels and liquefied natural gas bunker sales surpassed 700,00 metric tonnes.

To support the operationalisation of a higher mix of low-carbon alternative fuels, both EnterpriseSG and MPA are developing the Singapore standards for methanol bunkering and ammonia bunkering by 2024 and 2025 respectively.

The standards will cover custody transfer requirements, safety procedures and crew competencies, to ensure safe bunkering operations and handling of these fuels.

MPA also announced that three major shipping lines — Hafnia, K-Line, and MOL — are in early discussions to join the Singapore - Port of Los Angeles (LA)- Port of Long Beach (LB) Green and Digital Shipping Corridor (GDSC) initiative.

Each partner would be expected to spearhead a project to advance the corridor’s decarbonisation and digitalisation goals, such as the adoption of net-zero fuels, Just-in-Time route optimisation, and energy efficiency technologies such as wind-assisted ship propulsion.

The addition of the new partners will significantly strengthen the GDSC’s capacity to drive innovation in sustainable shipping practices and accelerate the adoption of zero/near-zero emission fuels and green technologies along the corridor.
