What Oasis Marine Ltd does

Oasis Marine Ltd is a UK-based engineering company developing offshore mooring buoys that allow vessels to moor and recharge using clean electricity generated by nearby offshore wind farms. Its core product, the Oasis Power Buoy, is described as the world's first in-field offshore charging buoy, enabling hybrid and all-electric Crew Transfer Vessels (CTVs) to eliminate diesel idling and transit emissions while waiting on station. The portfolio has been expanded to include the Oasis SOV Buoy for larger Service Operation Vessels, the Oasis Fuelling Buoy for ammonia/methanol transfer, and the Oasis Hydrogen Buoy for offshore hydrogen bunkering, with an integrated Intelligent Power Conditioning and Management System paired with Verlume's Halo battery storage.

The business operates as a pre-commercial hardware company monetising bespoke buoy deployments to offshore wind developers, alongside grant-funded engineering and demonstration services delivered through consortium projects. Revenue mechanics are enterprise/quotes-based with no public pricing, and the firm has no disclosed commercial sales to date — a pilot demonstration at a UK wind farm is scheduled for 2025. The company was established in 2013 (parent Jebb Smith Ltd, SC465842) with the Oasis Marine Power Ltd subsidiary created in 2020; it is privately held with Wilkie Engineering Ltd holding a strategic manufacturing and shareholder relationship.

Go-to-market is direct enterprise sales led by a Business Development Director targeting offshore wind operators (ScottishPower Renewables, Vattenfall) and adjacent vessel operators (O.S. Energy for hydrogen-powered vessels, GXS Viking for CTV trials), supported by participation in maritime industry events, an active LinkedIn channel, and a downloadable ScottishPower-commissioned feasibility report. Key technology and consortium partners include Turbo Power Systems (power conversion), First Marine Solutions (mooring design), Verlume (energy storage), University of Strathclyde (wave tank testing), and ORE Catapult (project management and verification).

Core offering

Oasis Marine Ltd designs, manufactures and supplies offshore mooring buoys that enable hybrid and all-electric vessels to recharge from wind farm turbines. The Oasis Power Buoy is the world's first in-field offshore charging buoy, combined with the Oasis SOV Buoy for larger vessels, the Oasis Fuelling Buoy and Oasis Hydrogen Buoy for alternative fuel transfer. Products are sold to offshore wind operators and vessel companies for deployment in wind farm environments.

Product overview

Oasis Marine Ltd offers a portfolio of industrial mooring buoys for offshore charging and refuelling. The core product is the Oasis Power Buoy, the world's first in-field offshore charging station allowing vessels to moor and recharge directly from wind farm turbines. This integrates with the larger Oasis SOV Buoy for bigger service vessels. Complementing the charging solutions, the Oasis Fuelling Buoy and Oasis Hydrogen Buoy address future alternative fuel needs (ammonia, hydrogen, methanol) for maritime decarbonisation. Together, these products enable hybrid and electric vessels to operate using clean energy, reducing carbon emissions and fuel costs in offshore wind operations.

Expansion highlights6 records

Direct peers

• MJR Power & Automation: UK-based supplier of offshore power generation, electrical distribution and vessel charging systems for offshore wind crew transfer and SOV markets. Comparable as a direct peer addressing offshore wind vessel power/charging, with overlapping customers and use cases.

Emerging players

• Blue Logic: Norwegian supplier of subsea connectors, inductive couplers and intervention tools for offshore energy. Comparable as a niche subsea power/connectivity specialist whose inductive subsea charging interfaces are an alternative architectural approach to Oasis's moored power-buoy model.
• Subsea Energy Storage (Halo/Bramble Energy): Emerging subsea and hydrogen battery/storage technology companies addressing offshore wind energy storage needs. Comparable as emerging players in adjacent subsea power and storage components that Oasis integrates with or could face as competition.
• Verlume: Subsea energy storage specialist (Halo battery system) and Oasis Marine's named partner in the CMDC3 project. Comparable because it supplies adjacent in-field energy storage and intelligent power management for offshore wind assets, partially overlapping with Oasis's integrated charging and energy-conditioning offering.

Broad incumbents

• Cavotec: Established supplier of shore power and marine charging/electrification systems (Automated Mooring, PowerMove). Comparable because it provides the maritime charging and power-connection infrastructure layer, although its primary focus is shoreside rather than offshore wind-farm in-field deployment.
• Wärtsilä: Global marine technology major offering hybrid propulsion, energy storage and shore-power solutions. Comparable as a broad incumbent supplying marine electrification, hybrid and future-fuel vessel infrastructure across shipping segments that Oasis also targets.
• ABB Marine & Ports: Major marine electrification and propulsion supplier (Onboard DC Grid, shore power). Comparable as a broad incumbent with overlapping marine power conversion and charging solutions, although serving a wider customer base beyond offshore wind.
• Aker Solutions: Large offshore engineering, substructures and offshore wind balance-of-plant contractor. Comparable as a broader offshore-wind infrastructure provider that could compete for or partner on the marine engineering scope of offshore charging deployments.
• Tideway BV / Van Oord: Major offshore marine contractors active in offshore wind cable installation, foundations and balance-of-plant. Comparable as broad incumbents that operate the vessel fleets and subsea installation scope that would integrate Oasis buoy deployments within offshore wind construction and O&M contracts.
• Siemens Energy (Offshore Wind / Grid Access): Global offshore wind turbine and grid connection equipment supplier (including HVDC and offshore substation technology). Comparable as a broad incumbent whose offshore wind electrical infrastructure footprint could either adopt or compete with Oasis's buoy-based charging approach.
