Mainstay Optimizer
Sustainable subsea hull cleaning that saves fuel, money, time and the environment.
The Optimizer is a mobile hull cleaning unit equipped with an efficient filtration system for macro particle collection. The specially designed brushes ensure gentle cleaning, minimizing abrasion of the antifouling coating while maintaining a clean and fuel-efficient hull. Download the data sheet below.
Stop wasting marine fuel!
Hull fouling can increase fuel consumption by over 9%, leading to higher costs and emissions across your fleet. The Mainstay Optimizer offers an innovative solution: it cleans ship hulls below the waterline while vessels remain in service – no drydocking, no downtime. By keeping your hull smooth and free of growth, the Optimizer helps reduce drag, lower fuel use, and improve overall efficiency. It’s a simple, sustainable step toward smarter fleet operations.
The Mainstay Optimizer stops the loss.
Microfouling doesn’t just appear overnight – but if left unchecked, it builds resistance and adds to your operating costs. The Mainstay Optimizer targets the problem early by capturing biofouling and particles as small as 100 microns. This reduces drag before it can affect performance, fuel consumption or emissions. With automated subsea hull cleaning that fits into your regular maintenance routines, it helps you stay ahead of the problem – quietly, cleanly and efficiently.
Soft on coatings. Tough on fouling.
Hull coatings are a vital line of defense – but traditional cleaning methods can damage them, reducing their long-term effectiveness. The Mainstay Optimizer uses soft nylon brushes, designed to remove fouling without harming the protective coating beneath. This gentle yet thorough cleaning helps preserve both performance and coating lifespan, while capturing removed particles to prevent contamination. It’s a smarter way to maintain your hull – preserving value while protecting the environment.
Prevent growth before it anchors in.
Fouling starts small – with invisible micro-organisms that later become full-grown drag. The Mainstay Optimizer is designed for proactive hull care: it removes microfouling before it becomes a bigger, costlier problem. By stopping the growth cycle early, the system helps reduce the frequency of major hull cleaning and maintains a clean, efficient surface over time. The result? Less downtime, lower emissions, and cleaner operations – right from the start.
