The value of the wind — WAPS by Stramba

The market of WAPS

A market in a dynamic growth phase

The WAPS market is in a dynamic growth phase, driven by increasing environmental regulations and decarbonization efforts.

WAPS harness the power of wind to supplement the propulsion of ships, reducing reliance on fossil fuels. Less fuel burned means lower fuel bills, fewer emissions and less carbon to pay for.

ECONOMIC ADVANTAGES

Fuel savings

WAPS directly reduce fuel consumption by supplementing the main engine's power: a saving that grows with fuel prices.

Unlike alternative fuels (LNG, methanol), WAPS need no new fuel infrastructure or supply chain.

Carbon cost avoided

Every tonne of CO₂ not emitted is a tonne you do not have to cover with EU ETS allowances on EU voyages.

Wind-assisted propulsion is also recognised by FuelEU Maritime.

Return on investment

The investment is real, and the return comes from lower fuel and carbon costs over the ship's life.

Payback depends on ship type, operating profile and prices: we evaluate it with you, ship by ship.

MAINTENANCE ADVANTAGES

Simple technology

Compared to scrubbers or exhaust gas recirculation, WAPS are mechanically simpler and automated, with little manual intervention.

Low maintenance

No chemical processes, no waste to dispose of: less downtime and lower maintenance costs.

Longevity

Well built wing systems are designed for a long operational life, adding to their economic benefit.

Assumptions

Fuel burned = power × load × 24 h × days × specific consumption (HFO 0.195, VLSFO 0.185, MGO 0.185, LNG 0.140 kg/kWh). CO₂ factors (t CO₂ per t fuel): HFO 3.17, VLSFO 3.11, MGO 3.20, LNG 2.75. Scenarios set fuel and carbon price: low = HFO €430/t and €65/t CO₂; average = VLSFO €550/t and €90/t CO₂; high = MGO €950/t and €120/t CO₂ (change them freely; LNG price is yours to enter). EU ETS avoided = CO₂ avoided × carbon price × voyage share, at 100% phase-in. Not included: FuelEU Maritime effects, CII rating, port costs, installation and maintenance. Indicative only.

COMPARISON WITH OTHER EMISSION REDUCTION SYSTEMS

Scrubbers	Effective on sulfur emissions, but they consume energy and require ongoing maintenance and disposal of waste products. WAPS reduce the fuel burned in the first place, lowering all emission outputs.
Alternative fuels LNG, methanol, ammonia	They need significant infrastructure changes, including new fuel tanks and supply systems, and pose safety and handling challenges. WAPS work together with alternative fuels to reduce emissions further.
Exhaust Gas Recirculation (EGR)	EGR systems add mechanical complexity and maintenance to the engine, and mainly reduce NOx. WAPS act on a much wider array of pollutants.
