Optimarin has unveiled its latest ballast water treatment system (BWTS), Optimarin Guardian, which is designed to meet the evolving needs of vessel operators, especially in light of geopolitical uncertainty and rising energy costs.
Guardian is designed to combine high treatment efficiency with low power consumption and reduced lifecycle cost. The launch is part of Optimarin’s broader strategy to respond to changing market dynamics through increased supply chain flexibility, expanded service offerings, and an enhanced technology portfolio following the acquisition of Hyde Marine’s UV BWTS technology.
Tonje Olafsen, VP Sales and Projects, said: “Guardian reflects what the market is asking for: flexibility, reliability, and predictable costs. Shipowners and yards are under pressure. With Guardian, we offer a cost-effective and compliant solution backed by the service reach and engineering depth Optimarin is known for.”
The new system is optimised for large vessel segments but will also be available in a compact 60m³/h version, making it suitable for smaller vessels, an expansion that broadens Optimarin’s addressable market.
Guardian leverages Optimarin’s proven technology while significantly improving energy efficiency. Early feedback from selected pilot installations has indicated measurable performance gains in both power usage and operational uptime.
Supply chain disruptions remain a top concern across maritime sectors. Optimarin says it has implemented a flexible, regionally distributed parts sourcing model that minimises delivery delays and supports localised service in key regions such as Europe, Asia, and the Middle East.
Olafsen said: “We’ve spent the last few years quietly building redundancy into our supply chain. Now that global logistics are under strain, we’re able to maintain delivery reliability while competitors struggle.”
In addition to launching Guardian, Optimarin is emphasising its service model as a key differentiator. With a global team of field engineers and service support, the company has introduced tailored service agreements aimed at helping operators minimise downtime and gain better visibility into long-term maintenance costs. The company reports increasing uptake of these agreements, particularly from owners seeking predictability in the face of tightening margins and stricter compliance timelines.
Following its acquisition of Hyde Marine’s BWTS technology, Optimarin now offers a significantly broader product portfolio. The integration has strengthened its UV technology base, expanded engineering capabilities, and enabled more tailored solutions for diverse vessel types.
