EPS Pays for Wind Sails Out of Verified Fuel Savings

Eastern Pacific Shipping has financed suction sails on two vessels through a fund that ties repayment to independently verified fuel savings — a first for shipping's wind-assisted propulsion segment.

The ships, Pacific Sentinel and Pacific Sunstone, each carry three 22-metre suction sails. They're the first in the Singapore-based owner's fleet to adopt wind-assisted propulsion. The financing comes from the Fund for Energy Efficiency Technologies, or FEET, which has now made its debut deployment with the EPS projects.

AIM Horizon Investments manages the fund. The Global Centre for Maritime Decarbonisation (GCMD) serves as its decarbonisation adviser. Behind the money sit three banks: the Development Bank of Japan, DBS Bank and ING. The partners want to stretch the model across other efficiency technologies and other fleets.

How does the repayment actually work?

FEET offers up to 100% upfront financing for energy-efficiency kit. Shipowners then pay based on verified fuel and regulatory savings — not on projections, not on vendor promises. Independent verification precedes every payment calculation.

That structure matters because efficiency retrofits have long lived in a credibility gap. Owners hesitate to pay for savings they can't prove; financiers hesitate to fund savings they can't measure. This deal attempts to close both gaps at once.

The verification method isn't theoretical. It rests on trials GCMD and EPS ran aboard Pacific Sentinel between May and September 2025, while the ship traded in the Americas.

What did the trials measure?

Plenty. Researchers collected 276 million data points over four months of trading. The analysis examined 203 valid sail on-off transitions — switching the sails off and on in real conditions to isolate their effect on fuel consumption from everything else: weather, speed, cargo, trim.

The methodology has been through independent review. That's the foundation on which future project savings will be verified before anyone pays anyone.

203 controlled transitions over four months is a serious dataset for a shipping trial. It's roughly one and a half sail cycles per day, every day, across an entire trading programme.

"Decarbonisation moves faster when the technology, the data, and the financing come together," EPS chief executive Cyril Ducau said.

Dry, but accurate. Technology without financing stalls at pilot scale; financing without data stalls at the credit committee.

What does this change for owners and lenders?

For shipowners, the appeal is straightforward: near-zero capital outlay for a retrofit that cuts fuel burn. For lenders, the verified-savings mechanism converts an efficiency project into something resembling a measurable revenue stream. For the wider market, it offers a template that doesn't depend on green premiums or charterer goodwill.

Suction sails themselves aren't new — several owners have fitted them — but the payment structure is. Linking instalments to independently audited savings, rather than to installation milestones, shifts performance risk from the owner to the technology and its measurement.

The banks' involvement signals institutional appetite. DBJ, DBS and ING aren't venture money; they're balance-sheet lenders testing whether verified efficiency can be underwritten like an asset class.

Where it goes next

The partners explicitly aim to extend the financing model beyond wind to other energy-efficiency technologies across shipping fleets. Air lubrication, hull coatings, waste-heat recovery and engine retrofits all fit the same logic: measurable fuel savings, verified independently, repaid from the saving itself.

If the Pacific Sentinel data holds up across more deployments, the industry gains something it has lacked — a repeatable, bankable pathway for efficiency capital. Watch whether FEET's second deployment arrives quickly, and whether it leaves wind behind.
