Infineum: IMO approves emissions cuts

Improving the fuel economy performance of existing ship operations is also an approach to cutting emissions, and it is an area where advanced lubricants can help.

International fuel additive company Infineum on Tuesday (12 January) published an article on how the maritime industry will be affected by upcoming carbon emission regulations and how a quality lubricant can help to ease the process and ensure compliance:

The introduction of the International Maritime Organization (IMO) legislation to reduce fuel sulphur, just one year ago, which was expected to have a huge impact on shipping and its associated industries, seems to have gone fairly smoothly. To date, there have been only a few reports of availability issues, off-specification fuels and some concern over increased cylinder liner wear. Insight explores these issues and reports on the upcoming greenhouse gas emissions reduction measures recently approved by the IMO Environment Committee.

At the end of 2019, those associated with the shipping industry were busy assessing how best to comply with the immanent IMO sulphur requirements. These IMO 2020 regulations meant, from January 1 2020, ships would be unable to use fuels containing more than 0.50% sulphur, unless fitted with an appropriate exhaust gas cleaning system. At the time it was billed as the ‘biggest thing that has happened to shipping for a century’, with implications for the whole industry from refiners and bunkerers, ship operators and owners to lubricant and additive suppliers.

Despite the uncertainties around the impact on refinery product mix, compliant fuel availability and ship operability the transition to the new low sulphur norm passed with little fanfare and relatively few issues.

Sediment and wear

Throughout 2020 the Lloyds Register fuel oil bunker analysis advisory service (FOBAS) issued seven bulletins regarding fuel quality issues, which have been associated with sediment levels, water and flash point. Total Sediment Potential (TSP) exceeding the specified ISO 8217 limit of 0.10% mass has been reported at Rotterdam, Balboa, Singapore and Port Elizabeth. The TSP results of these off-specification fuel samples ranged from 0.16–0.43% mass.

The use of high TSP fuels can also result in highly compromised combustion leading to engine and turbocharger damage. In August 2020, FOBAS suggested that the issue of high TSP with these ‘new’ fuels was becoming a more regular occurrence. In our view, to ensure fuels do not cause serious operational issues it is essential to fully understand the TSP level of the fuel throughout its lifetime on board.

As the world emerges from the impact of the COVID-19 pandemic, marine fuel manufacturers and blenders are likely to stretch their formulation boundaries in order to optimise sourcing costs.  This means the continued monitoring of fuel quality will be important in order to determine if further sedimentation and other quality and operability issues surface.

In September, FOBAS issued a report showing excessive cylinder component wear in large two-stroke engines during the use of 0.50% sulphur fuels. Its data indicate that overall incidents related to cylinder component damage almost doubled for the period November 2019 to June 2020 vs. the same period in 2018/19.

Cylinder lubricant quality could be a contributing factor here. It is important to understand that it is not just a matter of taking current technology that works in a high sulphur fuel environment and down treating it for use in a low sulphur fuel situation.

Formulations in heavy sulphur fuel oil environments can be almost completely detergent that comprise a core, which provides the neutralising power to handle the acids from the sulphur in the fuel. This core is stabilised by the surfactant that comes as a chemical sheath. If the neutralisation power is removed in a lower sulphur fuel environment then coincidentally the ability of the detergent to clean up the vessel is reduced.

The shipping industry has been hard hit by the COVID pandemic. Year-on-year port calls of container ships went down by as much as 8.5% in mid-June. They have somewhat recovered, but in early August were still 3% below the levels of one year earlier. Forecasts expect maritime trade growth to return to a positive territory in 2021, assuming world economic output recovers. As the shipping industry picks up, it will be interesting to see if there is also an increase in the incidence of issues, and if they are related to the use of VLSFO.

IMO approves further emissions cuts

Despite the challenges and uncertainties facing the marine industry, post-COVID-19 recovery policies need to support further progress towards green solutions and sustainability. Carbon emissions from shipping are already coming under scrutiny.

In November, the IMO Marine Environment Protection Committee (MEPC) approved amendments to cut emissions from existing ships. Draft new mandatory regulations require ships to combine a technical and an operational approach to reduce their carbon intensity. This is in line with the Initial IMO GHG Strategy, which aims to reduce carbon intensity of international shipping by 40% by 2030, compared to 2008.

Current requirements are based on the Energy Efficiency Design Index (EEDI), for new build ships, which means they have to be built and designed to be more energy efficient than the baseline; and the mandatory Ship Energy Efficiency Management Plan (SEEMP), for all ships. The draft amendments build on these measures by bringing in requirements to assess and measure the energy efficiency of all ships and set the required attainment values.

The latest set of amendments include the technical requirement to reduce carbon intensity, based on a new Energy Efficiency Existing Ship Index (EEXI) to be calculated for ships of 400 gross tonnage and above, which indicates the energy efficiency of the ship compared to a baseline. Ships will be required to meet a specific EEXI based on a reduction factor relative to the baseline. Also included are the operational carbon intensity reduction requirements, based on a new carbon intensity indicator (CII) for ships of 5,000 gross tonnage and above, which determines the annual reduction factor needed to ensure continuous improvement of the ship’s operational carbon intensity within a specific rating level. The dual approach aims to address both technical (retrofitting and equipment) and operational measures.

While switching to alternative fuels is one approach to cutting emissions, improving the fuel economy performance of existing ship operations will become increasingly important; an area where advanced fuels and lubricants can help. Improving combustion efficiency and the use of lower viscosity lubricants to ensure more energy is transferred into forward propulsion are elements that Infineum has already proven in passenger car and heavy-duty diesel truck applications. The experience gained here, both on the lubes and the fuels side, can be used to evolve rather than revolutionise fuel economy technology for the marine industry.

RESIZED ENGINE Europe and Africa

The following article regarding Europe and Africa bunker fuel availability has been provided by online marine fuel procurement platform ENGINE for post on Singapore bunkering publication Manifold Times:

  • East Mediterranean ports see high demand
  • Malta sees rough weather
  • High demand increases lead times in West Africa

Northwest Europe

Availability of all fuel grades is stable in the ARA bunkering hub, but buyers are recommended to enquire about stems around five days ahead to get competitive offers from a wide selection of suppliers, a trader said.

The ARA’s independently held fuel oil stocks slumped 20% lower in March, according to Insights Global data.

The region imported around 160,000 b/d of fuel oil in March, down from 192,000 b/d imported in February, according to cargo tracker Vortexa. Most supplies have arrived from Denmark (21%), Poland (14%) and Libya (13%).

The region’s independent gasoil inventories – which include diesel and heating oil – have dipped 1% lower in March, compared to February.

The ARA imported 289,000 b/d of gasoil, down from the 304,000 b/d in February, according to Vortexa data. Around 27% of cargo volumes have come from Kuwait, while the US has sent around 24%.

In Germany’s Hamburg, buyers are being advised to book stems with a lead time of five days, a trader said.

Bunker fuel availability is very tight in Sweden’s Gothenburg and off Denmark’s Skaw, a trader told ENGINE.

Mediterranean

Securing supplies promptly is challenging in the Gibraltar Strait ports, and buyers are advised to book around seven days in advance to secure supplies of any fuel grade, a trader said.

Demand is stable in the Port of Gibraltar, with around 40 vessels expected to call for bunkers between 1-8 April, shipping agent A Mateos & Sons said.

Congestion caused in the port last week due to rough weather conditions has completely cleared as of Wednesday morning, port agent MH Bland said.

In Barcelona, buyers are usually requested to give a week’s notice for any delivery, but supplies can be arranged sometimes on a prompt basis, a trader told ENGINE.

Bunker availability is tight in the Canary Islands bunkering hub of Las Palmas, a trader said. Suppliers are giving earliest delivery dates around 10 days out for stems with competitive prices, the trader added.

Bunkering operations are currently being conducted in the inner anchorage and at the berth due to rough seas, port agent MH Bland said.

Malta is experiencing rough winds of more than 25 knots and waves of more than 2.5 metres, and the conditions are expected to persist until 3 February.

Bunkering operations off Malta have been currently suspended, port agent MH Bland said.

Some operations can be conducted in the sheltered Area 1 and Area 4, and operations are expected to resume normally in the offshore area around Saturday, shipping agent WMR told ENGINE.

Bunker demand has decreased recently off Malta, a trader said.

Fuel availability is steady in the Greece’s Piraeus, but high demand for bunkers is causing operational challenges related to barge and berth availability, a local supplier said. The port may face tight product availability around late April or early May if the conflict continues and crude flows through the Strait of Hormuz continue to remain disrupted, the supplier added.

Fuel availability is stable in Turkey’s Istanbul and demand is very strong, a local supplier told ENGINE. Buyers are securing bunkers as they anticipate tight availability next month, the supplier added.

Africa

Ships re-routing around the Cape of Good Hope have increased bunker demand in African ports, suppliers and traders told ENGINE.

West African ports are experiencing low product availability as demand is rising and supply is not able to keep up, a major supplier in West Africa said.

Lead times have increased significantly in many bunkering hubs due to the additional demand.

In Togo’s Lome and off Namibia’s Walvis Bay, buyers are recommended to enquire about stems around 10-11 days ahead, a trader said.

In Angola’s Luanda, one supplier has stopped supplying VLSFO, while LSMGO supplies may need around 7-10 days of notice, a supplier told ENGINE.

Getting VLSFO supplies in Nigeria’s Lagos anchorage also requires around 10 days of notice, a local supplier said.

In South Africa, availability is stable off Algoa Bay, a trader said. In Durban, LSMGO is priced around $3000/mt.

IMO: Caribbean maritime leaders draft policy recommendations to decarbonize shipping

The International Maritime Organization (IMO) on Tuesday (3 February) said Caribbean policymakers and financiers have emphasized that decarbonization will not succeed through isolated projects or technologies alone, but through coordinated action across sectors and countries, supported by evidence-based planning and investment-ready pathways. 

Senior representatives from Caribbean governments, maritime administrations, ports, energy authorities, development banks and financial institutions met for a regional roundtable convened in Port of Spain, Trinidad and Tobago (29 – 30 January) by IMO’s GreenVoyage2050 Programme, in collaboration with Global MTCC Network (GMN Phase II). 

The event, under the theme Unlocking maritime decarbonization, resulted in key draft policy recommendations for the region, including proposals for: 

  • enhanced regional coordination to harmonize national policies; 
  • knowledge-sharing; 
  • capacity building; and 
  • investment facilitation.  

Participants focused on moving from analysis to implementation by aligning policy, infrastructure planning, energy systems and finance. The participation of multilateral and regional development banks alongside policymakers and industry linked technical ambition with financial realism at an early stage. 

Dr Jose Matheickal, Director of the IMO’s Technical Cooperation and Implementation Division, underscored the need to bridge global ambition and national delivery: “The IMO GHG Strategy sets a clear global direction, but implementation happens at country and regional level. What is critical is creating the conditions, policy, institutional capacity and credible project pipelines, that allow finance to flow and turn ambition into action.” 

The first day of discussions connected the 2023 IMO GHG Strategy with delivery through technical cooperation and regional collaboration.  

Findings from the Jamaica Maritime Alternative Fuels Study, supported by the GreenVoyage2050 Programme, were shared to ground the regional dialogue in a concrete country example. The study illustrated how Caribbean States can assess future fuel demand, supply pathways, infrastructure needs and policy implications to inform investment and planning decisions. 

Building on this evidence, participants discussed credible fuel pathways for the region, barriers to adoption and where regional coordination could accelerate progress. Interactive mapping exercises captured existing initiatives, infrastructure gaps and opportunities for collaboration across the Caribbean, while practical examples demonstrated how policy intent is already translating into action through green port development, fleet initiatives and pilot projects. 

 

The second day of the roundtable focused on unlocking investment, with development banks and financial institutions outlining what is needed to improve project bankability and mobilize public and private finance.  

Discussions explored financial instruments, risk-sharing approaches and policy signals required to support investment in ports, clean fuels and maritime infrastructure, reinforcing the importance of aligning national priorities with financier expectations. 

Ms Thandi McAllister, Director – Legal Services, Maritime Administration Department, Guyana, said: “This Regional Roundtable provided a vital platform for States and other maritime stakeholders to gain valuable insights into the impact and opportunities that are optimizable by Caribbean SIDs and LDCs in their pursuit of decarbonisation goals.” 

Finally, the participants visited the ammonia-fuelled ship Fortescue Green Pioneer for a first-hand look at alternative fuel technology in use onboard.

ICS and 47 governments submit GHG pricing mechanism proposal to IMO

Key purpose of mandatory GHG charge will be to reduce cost gap between zero/near-zero GHG emission fuels and conventional bunker fuels to incentivise accelerated uptake of green energy sources.

IMO

The International Chamber of Shipping (ICS) on Thursday (9 January) said it has joined 47 governments in a joint submission to the final round of negotiations at the United Nations’ International Maritime Organization (IMO) to adopt a maritime greenhouse gas (GHG) emissions pricing mechanism to achieve net zero GHG emissions from international shipping by 2050. 

The joint text is supported by major shipping nations such as Greece, Japan, Korea and the United Kingdom, the world’s largest flag States including Bahamas, Liberia, Marshall Islands and Panama, all EU States (and the European Commission), other African countries such as Nigeria and Kenya, plus Small Island Developing States from the Caribbean and the Pacific.

The joint submission by governments sets out convergent regulatory text for amendments to the IMO MARPOL Convention, which will require shipping companies operating ships on international voyages to make GHG contributions per tonne of CO2e emitted to a new “IMO GHG Strategy Implementation Fund”.

ICS said the key purpose of this mandatory GHG charge will be to reduce the cost gap between zero/near-zero GHG emission (ZNZ) fuels such as green methanol, ammonia and hydrogen and conventional bunker fuels, to incentivise the accelerated uptake of green energy sources. 

Revenue generated will be used to reward the production and uptake of ZNZ marine fuels, whilst also providing billions of US dollars annually to support the maritime GHG reduction efforts of developing countries.

International Chamber of Shipping Secretary General, Guy Platten, said: “The industry fully supports the adoption by IMO of a GHG pricing mechanism for global application to shipping.”

“The joint text put forward by this broad coalition is a pragmatic solution and the most effective way to incentivise a rapid energy transition in shipping to achieve the agreed IMO goal of net zero emissions by or close to 2050.”

“We are very pleased that such a large and diverse group of nations now firmly supports a common approach to maritime carbon charging. This proposed joint text has been hard fought and is broadly based on ideas which ICS has been advocating for the past ten years.

“While a large number of governments now support a universal flat rate GHG contribution by ships – or something similar – a minority of governments continue to have concerns. Working in co-operation with all IMO Member States we will do our best to allay such concerns during the final stages of these critical negotiations about regulatory text.”

This mature regulatory proposal will be considered by a critical IMO meeting in February – in the week of 17 February 2025 at ISWG-GHG 18. 

If the MARPOL amendments are approved by IMO in April 2025, they should enter into force globally in early 2027, with the collection of annual GHG contributions from ships commencing in 2028.
