Singapore | November 20, 2025 – The Global Centre for Maritime Decarbonisation (GCMD), alongside AIM Horizon Investments and a powerful consortium of financial partners, has announced the successful closure of the Fund for Energy Efficiency Technologies (FEET). The fund secured total commitments of up to USD $35 million, exceeding its initial target, and marks a paradigm shift in how vessel energy efficiency retrofits (EETs) are financed globally.
FEET is distinguished as the world’s first fund for vessel retrofits to leverage a pay-as-you-save repayment mechanism, directly tackling the historical financial uncertainties that have slowed the adoption of crucial decarbonisation technologies in the shipping sector.

FEET: Decoupling Financing from Vessel Mortgages
The core innovation of FEET lies in its ability to offer an unsecured financing solution, thereby decoupling retrofit financing from the vessel’s existing mortgage structure—a major bottleneck for shipowners.
Key Features of the FEET Fund:
- Up to 100% Upfront Financing: FEET provides full financing for the equipment, installation, and sensorisation costs associated with retrofits.
- Pay-as-You-Save Repayment: Repayment is directly linked to quantified and verified fuel and regulatory savings, eliminating payback uncertainty for the shipowner.
- Unsecured Leases: By offering unsecured leases, FEET avoids complex renegotiations with existing secured financiers, accelerating EET uptake.
- Ownership Transfer: At the end of the lease term, the ownership of the EET is transferred to the shipowner for a nominal fee.
GCMD provides catalytic equity and serves as FEET’s appointed decarbonisation advisor, ensuring that the projects align with rigorous performance and sustainability standards.
A Blended Financing Structure Drives Resilience
FEET is managed by AIM Horizon Investments, a Singapore-based fund manager specialising in maritime and aviation funds. The fund has attracted a robust blend of capital, designed to balance financial risk while maintaining competitive financing costs.
- Commercial Equity: Held by shareholders of AIM Horizon Investments.
- Preferred Equity: Held by the Development Bank of Japan Inc. (DBJ).
- Senior Debt Financing: In principle agreement secured from DBS Bank and ING (which also acted as Coordinating Bank).
- Catalytic Capital: Provided by GCMD.
This diversification across various technologies, manufacturers, vessel owners, and vessel types spreads investment exposure and significantly enhances the fund’s resilience.

Addressing the $20B Retrofit Market’s Pain Points
Improving energy efficiency through EETs—such as Wind-Assisted Propulsion Systems (WAPS) and Air Lubrication Systems (ALS)—is crucial for immediate fuel cost reduction and maintaining competitiveness under tightening regional carbon regulations.
However, the over USD $20 billion retrofit market has historically been hampered by two main issues:
- Variable Fuel Savings: Savings are inherently dependent on operational and environmental factors (e.g., routing and weather), making the Return on Investment (ROI) period difficult to predict.
- Split-Incentive Issue: Shipowners are expected to invest in retrofits, while charterers often realise the immediate fuel savings.
FEET’s pay-as-you-save model is a direct solution, requiring robust data collection and analysis—an area where GCMD has been active through its EET performance pilots—to isolate and verify the retrofit’s specific contribution to fuel savings with statistical confidence.
Poised for Massive Scale and Industry Impact
The initial closing is just the first step. GCMD and AIM Horizon Investments have an ambitious target to scale FEET to USD $500 million by 2030. This scale would be capable of supporting retrofits on approximately 200 ships.
Professor Lynn Loo, CEO, GCMD, said: “Bringing FEET to life has taken persistence and a willingness from everyone involved to step into the unknown. There was no playbook; our teams were learning as we went. This is exactly the kind of collaborative, problem-solving mindset needed to move the needle on maritime decarbonisation.”
Several projects have already been identified and progressed to the final investment decision stage, reflecting strong and immediate industry confidence.
Voices from the Partnership
Michiel Muller, Partner AIM Horizon & FPG AIM, highlighted the collective effort: “We are proud to work in this partnership and bring an innovative financial product for maritime decarbonisation. It has taken a huge collective effort to create a solution that immediately reduces carbon emissions and has competitive economics that will enable it to really scale.”
Stephen Fewster, Global Head of Shipping, ING, affirmed the commitment: “We are therefore delighted and honoured to have collaborated with GCMD and our partners to drive the adoption of energy efficiency retrofits which are key for shipping’s decarbonisation. We look forward to further cooperation and scaling this innovative solution.”
Max Lim, Managing Director and Group Head, Shipping, Aviation, Logistics & Transportation, DBS, stressed the opportunity: “The FEET initiative not only supports the adoption of technologies for energy efficiency, but also seeks to help shipowners manage financial and climate risks. DBS is proud to be a partner in this pioneering effort.”
Corporate Finance Department, Division 4, DBJ, said: “We believe that the adoption of EETs is an effective solution for maritime decarbonisation. FEET provides a platform to support this, and DBJ has decided to invest in the fund. We are proud to be involved in such an international and ambitious initiative, and we sincerely hope that FEET’s efforts will expand and contribute to the decarbonisation of the maritime industry.”
EET Technology Spotlight: WAPS and ALS
The Fund for Energy Efficiency Technologies (FEET) is designed to accelerate the adoption of proven Energy Efficiency Technologies (EETs) that deliver immediate fuel and emissions savings. The primary technologies FEET will finance include:
1. Wind-Assisted Propulsion Systems (WAPS)
WAPS technologies harness the natural power of wind to supplement a vessel’s main engine, generating aerodynamic forces to propel the ship. This reduces the engine load, resulting in significant fuel savings and emission reductions (often cited in the range of 5% to over 25%, depending on the system and vessel type).
- Key WAPS Types: These systems are an evolution of traditional sails, incorporating modern materials, automation, and intelligent controls. Common technologies include Flettner Rotors (spinning cylinders that use the Magnus effect to create thrust), Rigid Wing Sails, and Kite Sails.
- Decarbonisation Role: WAPS are considered a crucial “energy harvesting” technology, utilizing a free, inexhaustible, and zero-carbon energy source to help shipowners comply with tightening regulations like EEXI and CII.
2. Air Lubrication Systems (ALS)
ALS is a highly effective method for reducing a vessel’s frictional resistance, which can account for a significant portion of a ship’s total drag, especially for slower-moving vessels.
- Mechanism: ALS works by generating a continuous layer of microbubbles along the flat bottom of the ship’s hull. Air compressors supply air to dedicated release units (ARUs) on the hull.
- Efficiency Gain: The cushion of air reduces the contact between the hull and the seawater, lowering the wall shear stress and frictional drag. Operational data indicates average fuel savings typically ranging from 5% to 15%, depending on the hull design, speed, and sea state.
- Other Benefits: In addition to fuel savings, ALS can also contribute to the reduction of underwater radiated noise and may help in mitigating bio-fouling growth.
