Sailing on Sea

Clean Shipping

Decarbonising the maritime industry one vessel at a time

Clean Marine develops products designed to minimise the environmental impact of maritime operations and extend the lifetime of a vessel.
Calling on first-hand seafaring experience and in-depth maritime engineering knowledge, our research and development teams create innovative products that offer practical solutions for forward-thinking shipowners wanting to stay one step ahead of increasingly stringent regulations.

'Glide' Rotor Sail

Utilising wind propulsion technology that has existed for over a hundred years, we have adapted and refined the design to meet the needs of today.

Clean Marine has developed and built their own Flettner rotor sail; wind flows over a rotating cylinder, or ‘sail’, to create a differential pressure and generate forward thrust, improving vessel efficiency.​


Our developed system has concluded positive on-land testing, and the plan is to install two of these sails on an LR2 in Q3 2024. We leverage in-house design and manufacturing capabilities to keep production costs low, making our Glide Rotor Sail significantly cheaper than many alternatives on the market.


Crafted by seasoned seafarers, our straightforward configuration makes it much easier to set up and maintain the sail than other more complex models. Clean Marine is in dialogue with an EU funding application company that will help owners navigate complex EU funding schemes.

Air Lubrication Systems

The Clean Marine ALS combines proprietary design and engineering with well-established air lubrication principles to deliver tangible efficiencies in maritime operations.

As regulatory pressures mount to reduce the environmental impact of shipping, ALS is a simple, non-environmentally intrusive solution for forward-thinking companies.


The Clean Marine ALS stands out with its automated control features that adapt seamlessly to varying vessel drafts, optimising performance under different conditions. This adaptability ensures consistent fuel savings and drag reduction, making it a versatile solution for a wide range of maritime vessels.


Clean Marine has installed ALS on two 50k dwt MR tankers and is in the process of installing on two more. Voyage data shows positive results within the range predicted by the Computational Fluid Dynamics (CFD) both in ballast and laden. The system can be retrofitted in less time than a normal DD/SS hence not adding time to the costly DD.

'Carbon Lens' Emissions Monitoring

Monitor, calculate and record the exact amounts of CO2 emitted from your vessel exhaust stack with our live CO2 monitoring system.

Carbon Lens is a software and hardware system that instantaneously records the actual weight of CO2 released from each funnel and presents this in KGs and MTs, for easy tracking and reporting.


The system serves two main purposes. Firstly, it eliminates clerical reporting errors by continuously monitoring output and storing this data in cloud software which is readily accessible by crew, operators, and technical departments.


Secondly, in the absence of actual emissions data for EU ETS reporting, the accepted formula to estimate carbon output assumes that 100% of the fuel deposited in the engine is burned. The number of EUAs that need to be purchased is determined on this basis, however, a combustible engine can never burn 100% of fuel, therefore, by producing evidence of actual emissions valuable savings can be achieved.
