The International Council on Clean Transportation on Wednesday (11 October) released a new working paper that analysed 615 samples of real-world NOx emissions from 545 ships operating in Danish waters between the North Sea and the Baltic Sea in 2019. 

Measurements for the Real-world NOX emissions from ships and implications for future regulations working paper were obtained using sniffers attached to helicopters flown into exhaust plumes. The data includes measurements from ships covering all engine age categories (tiers).

The results were eye-opening: Newer Tier II engines had significantly higher NOx emission rates than older Tier I engines. Moreover, there was no statistical difference in NOx emission rates between unregulated Tier 0 engines and Tier II engines.

The greatest mean NOx emission rates were found at main engine loads below 25%, with emissions averaging 12 g/kWh across all vessel types and engine tiers. Emission rates decrease as main engine loads increase, with mean emission rates of 8.1 g/kWh at loads greater than 75%. Existing NOx test cycles assume that marine engines most often operate at higher engine loads; however, this study finds that engines typically operate at lower engine loads.

NOx regulations could be revised to make them more effective at reducing air pollution. Rather than relying on weighted emissions limits, the International Maritime Organization could consider implementing not-to-exceed (NTE) standards for new and existing ships, particularly focusing on operations at low loads, and including a test point below 25% load.

Singapore: Asia Pacific Maritime 2024 sets new record with highest attendance to date

The 18th Asia Pacific Maritime (APM), held from 13 to 15 March 2024, welcomed an unprecedented number of 15,717 attendees in Singapore, according to its organiser RX on Friday (22 March). 

This figure surpassed attendance records of previous editions, signifying a positive revitalisation of Asia Pacific's maritime sector and solidifying Singapore's position as a leading maritime hub.

Held at the Marina Bay Sands, the event showcased an extensive range of 710 exhibitors and featured 150 industry speakers worldwide. This year's theme, 'Future of Vessels, Solutions for Tomorrow', was a timely response to the industry's pressing need for sustainable and innovative solutions. 

“It fills me with great pleasure to be back at APM as a conference speaker. Participating in this edition was particularly humbling because I was able to meet many global exhibitors and speakers, all from diverse backgrounds. They offered various perspectives on the maritime industry's future,” said Punit Oza, Founder, Maritime NXT & International Vice President, Institute of Chartered Shipbrokers. 

“What stood out to me was the urgent need for decarbonisation. The topic took centre stage at APM 2024, with leaders coming forward to discuss solutions that will drive the industry's net-zero target. I'm glad to have been part of the conversations and look forward to more.”

The latest conversations to drive the maritime solutions for tomorrow 

As the world's largest bunkering hub preparing for a multi-fuel future, Singapore is the perfect location for industry players to convene. For instance, in the area of ammonia, although Singapore is driven by the intention of power generation, the country will start to generate the infrastructure and network for the maritime industry to leverage. As such, it is incredibly important for the industry to monitor and evaluate how we can keep pushing for these developments, because that will drive investments for the hub to transform and accommodate new fuels.

Other APM 2024 conference sessions such as Ship Design and Operations: Alternative Fuels for Decarbonisation of Shipping – The Safety Requirements dived into the safety measures for each fuel, which differs and depends on the characteristics of the fuel type. Another session titled Accelerating Green and Smart Ports Development Through Ecosystem Development discussed the need for eco-friendly infrastructures, technology integration, and ecosystems to develop green and smart ports.

APM 2024 also saw the return of exhibitors such as Speedcast, a global communications provider specialising in networking and application innovations.

A new report from Lloyd’s Register (LR), released recently, found that the total cost of ownership (TCO) for passenger ships retrofitted with methanol dual-fuel engines to be more than double the cost of blended fuel (Blend B30), heavy fuel oil (HFO) and HFO with Onboard Carbon Capture and Storage technologies (oCCS).

LR’s Fuel for thought: Methanol for Passenger Ships examined the TCO for operators over a 15-year period and based results on a calculation that 65% of voyage time would be spent in EU waters. 

Overall findings identified in the report, based on analysis by the LR Business Advisory team, show the bunkering price of methanol to be the main commercial barrier for its adoption, with the use of less environmentally friendly fossil based (grey) methanol a more commercially attractive proposition for passenger shipowners than a blend of 50% grey, 25% bio- and 25% e-methanol, even when EU emissions taxes are taken into account.

However, the study highlights that methanol is a technically viable fuel for ship operators looking to reduce the carbon emissions of passenger ship newbuilds, owing to the similar characteristics of methanol to existing fuels. 

Viable retrofit paths have also been taken to the sector, such as the pioneer LR project for the Stena Germanica back in 2015. This technical viability is reflected in the global orderbook with passenger ships ranging from small inland vessels to the largest cruise ships awaiting delivery.

The report also outlined that greater investment is needed in green and bio-methanol production along with improved bunkering infrastructure to increase fuel availability and reduce costs to a commercially viable level.

Natasha Pritchard, VP Strategic Key Accounts (Cruise), Lloyd’s Register, said: “Our latest Fuel for thought report brings some much-needed insights for passenger ship owners evaluating methanol as part of their energy transition pathway.”

“Whilst methanol as marine fuel holds considerable promise as a low carbon solution for passenger ship propulsion, the total cost of ownership (TCO) compared to other fuels may represent an obstacle to its widespread take-up in the segment.”

“It is therefore vital that renewable and low-carbon production of methanol is prioritised in order to drive down these costs.”
