Cost/Install Breakdown: Air Lubrication Systems
Updated 12/11/2024
In an era where fuel efficiency and environmental compliance are at the forefront of maritime shipping, Air Lubrication Systems (ALS) are emerging as a game-changer. This innovative technology is helping shipowners reduce operating costs, cut emissions, and stay ahead of global regulations like the IMO’s Carbon Intensity Indicator (CII) and Energy Efficiency Existing Ship Index (EEXI).
At its core, an air lubrication system creates a layer of microbubbles along the hull of a ship. These bubbles reduce the friction (or drag) between the ship’s hull and the water, allowing the vessel to move more smoothly through the sea. By reducing resistance, the ship can maintain speed while consuming less fuel — a win-win for shipowners looking to lower costs and emissions.

ALS Breakdown ⚙️
The system uses compressors to generate microbubbles that are released through specially placed nozzles along the bottom of the hull. These bubbles form a thin, continuous layer of air between the ship and the water, reducing surface friction. Here’s a step-by-step overview:
1️⃣ Air Compression: Air compressors generate high-pressure air.
2️⃣ Bubble Release: Air is pushed through a network of nozzles at the bottom of the hull.
3️⃣ Air Film Creation: The bubbles create a “cushion” of air between the hull and water, reducing drag.
4️⃣ Reduced Friction: The ship moves through the water with less resistance, lowering fuel consumption.
This process is completely automated and controlled by software that optimizes the release of air depending on voyage conditions (like ship speed, sea state, and vessel load).
Key Benefits of Air Lubrication Systems ✅
- Fuel Savings: Cut fuel consumption by 5-15%, reducing operating costs significantly.
- Emissions Reduction: Lower CO2 emissions, supporting compliance with IMO CII and EEXI regulations.
- Reduced Hull Wear: The air cushion also reduces contact with water, minimizing hull wear and extending the lifespan of hull coatings.
- Supports IMO Compliance: Helps shipowners meet carbon intensity targets, reducing the risk of non-compliance fines.
- Long-Term ROI: While the initial investment is high, the payback period can be as short as 3-5 years.

Payback Period Formula:Payback Period=Initial InvestmentAnnual Savings\text{Payback Period} = \frac{\text{Initial Investment}}{\text{Annual Savings}}Payback Period=Annual SavingsInitial Investment
To better illustrate how this works, let’s look at a real-world example.
3️⃣ Real-World ROI Example 🌍
Ship Type: Panamax Bulk Carrier
- Initial Installation Cost: $1.2M (total cost for system equipment, installation, and training)
- Fuel Consumption: 40 metric tons/day (MT/day) at $600/MT
- Fuel Savings from ALS: 10% (industry standard for ALS)
Step 1: Calculate Annual Fuel Savings
- Daily Fuel Use = 40 MT/day × $600/MT = $24,000/day
- Savings per Day = 10% of $24,000 = $2,400/day
- Annual Savings = $2,400/day × 300 sailing days = $720,000/year
Step 2: Calculate Payback Period
- Initial Investment = $1.2M
- Payback Period = $1.2M ÷ $720,000/year = 1.67 years
Step 3: Calculate ROI
- ROI = ($720,000 / $1.2M) × 100 = 60% per year
This shipowner would see a full payback within 1.67 years and continue saving $720,000 per year for the lifetime of the system (typically 10+ years).
