Segmental Insights

Why Does Bulk Carriers Dominate the Global Ballast Water Treatment Market?

The bulk carriers segment is expected to account for 36.0% of the global ballast water treatment market share in 2026. These ships carry commodities like iron ore, coal, grain and bauxite on international routes. Ballast water is taken on board to assist with vessel trim, draft, stability, and structural safety during loading and unloading operations. Their international trade patterns generate recurring requirements for uptake and release of ballast water at many ports. For large ballast tanks treatment systems are needed, capable of treating large amounts of water during ballast operations. The International Maritime Organization requires relevant ships to adhere to the Ballast Water Management Convention. For instance, Goltens retrofitted a ballast water treatment system on a bulk carrier in 2025. The project included an Optimarin system for 2,000 cubic meters per hour. The project involved an Optimarin system rated at 2,000 cubic meters per hour. Goltens used its retrofit engineering capabilities for the large-volume vessel application.

Why is Filtration the Most Crucial System Type?

The filtration segment is expected to account for 32.0% of the global ballast water treatment market share in 2026. Filtration is important because it serves as a primary physical barrier to organisms and suspended particles. Most of the ballast water treatment systems use filtration in combination with ultraviolet therapy or chemical treatment methods. Filters remove bigger organisms and particle materials before water flows to later treatment steps. This function decreases biological and particle load to downstream treatment equipment. Reducing the concentration of particulates can improve UV treatment conditions and reduce contamination in downstream components. Filtration is especially critical for vessels working in ports with elevated levels of suspended particles or sediment. Automatic backwashing systems can maintain filtration performance during continuous ballast operations.

On June 18, 2026, Norwegian Greentech announced it has been awarded several contracts to deliver a total of ten new ballast water treatment systems (BWTS) to various undisclosed shipyards and shipowners in Norway, Spain and the Netherlands. The majority of the BWTS systems will be delivered to newbuild vessels, including cable laying vessels, dive support vessels, offshore support vessels and live fish carriers.

Stationary Systems Dominates the Global Ballast Water Treatment Market

The stationary Systems segment is expected to account for 67.0% of the global ballast water treatment market share in 2026. Stationary systems dominate because they remain permanently integrated with the vessel's ballast water piping infrastructure. Permanent installation means treatment equipment can work with existing ballast pumps, valves, sensors and control systems. This arrangement avoids re-positioning of equipment during ballast water operations. Stationary systems also provide automatic treatment of treatment during vessel loading, unloading and ballast exchange operations. Commercial vessels that need to ballast ballast water frequently are particularly suitable to their permanent architecture. For large vessels, systems can be permanently fitted to match their flow rates and piping configurations. In February 2026, Knutsen Ballast Water commissioned two KBAL3000 systems aboard Janeiro Knutsen. The 154,000 deadweight-ton shuttle tanker uses two permanently installed filterless ultraviolet systems. The equipment was certified by the classification organization and the vessel owner at commissioning.
