Low-Cost Green Retrofitting Kits for Traditional Fishing Fleets

transportPilotedTRL 6

Imagine giving an old fishing boat a modern makeover to make it glide through water more easily and use less fuel. It's like adding a hybrid engine, solar panels, and a smart energy manager to a vintage car to save money on gas. The goal is to make these upgrades cheap and easy to install so boat owners actually want to do it.

The business problem

What needed solving

Traditional fishing fleets face high fuel costs and increasing pressure to reduce GHG emissions, but cannot afford to replace their entire fleet with new, expensive green ships.

The solution

What was built

A suite of retrofit kits including 50kW RIM drive motors, flexible silicon PV panels, air lubrication systems, and a cloud-based Eco-driving software.

Business applications

Who can put this to work

Maritime Transport
SME
Target: Small-scale commercial fishing fleet operator

If you are a fleet operator dealing with rising fuel costs and strict emission rules — this project developed a suite of retrofits including air lubrication and RIM drive motors that can reduce GHG emissions by up to 40%. This allows you to modernize without replacing your entire fleet.

Shipbuilding & Repair
mid-size
Target: Marine engineering shipyard

If you are a shipyard dealing with a lack of affordable green upgrade options for clients — this project developed recyclable thermoplastic composites and flexible PV modules. You can offer these low-CAPEX solutions to fishing vessel owners to increase their efficiency.

Renewable Energy
SME
Target: Marine solar panel manufacturer

If you are a manufacturer dealing with the harsh vibration and salt environment of ships — this project developed flexible silicon PV panels with anti-skipping and texturization. These are specifically designed for deck installation on fishing vessels.

Frequently asked

Quick answers

How much does the retrofitting cost?

Based on available project data, the specific price is not listed, but the project focuses on 'low CAPEX' and 'low OPEX' solutions to ensure a short payback time for boat owners.

Can this be scaled to larger ships?

The project specifically targets a 'broad range of small fishing vessels' and aims for scalable technologies that are easy to deploy across traditional fleets.

Who owns the intellectual property or licenses?

Based on available project data, licensing terms are not specified, but the project involves a consortium of 14 partners including 9 industry players.

When will these solutions be available for the market?

The project runs until 2027-04-30, with a goal of ensuring upscaling of the proposed solutions through 2029.

How is the technology integrated into existing boats?

Integration is achieved through retrofitting existing hulls with air lubrication, RIM drive pods, and flexible PV panels, managed by a cloud-based Eco-driving software.

Consortium

Who built it

The consortium is heavily industry-driven, with 9 industry partners (64% ratio) and 7 SMEs, indicating a strong focus on commercial viability rather than pure academic research. It spans 10 countries, providing a diverse market testing ground across the North Sea and Baltic Sea regions.
