Wärtsilä Sandguard
designed for vessels operating in abrasive waters

Wärtsilä Sandguard

The Wärtsilä Sandguard seal has been specifically designed for vessels operating in abrasive and polluted waters, and which require security against oil leakage into the seawater.

The face protector ring equipped in the seal works as an UNNET (active fishing net protection) and sand barrier device. The combination of a face protector ring and air control makes the Sandguard optimal for dredgers operating in challenging environments. This solution is designed to operate with EALs, ensuring your vessels are compliant with the 2013 US EPA Vessel General Permit. Wärtsilä offers bespoke solutions aiming to improve your vessel’s operational capability and availability.


Downtime can adversely affect your business and reputation. Our technical expertise and our innovative offshore solutions ensure your vessels operate with minimum disruption and maximum efficiency, even in harsh environments, extreme temperatures, with long operating hours, and constantly running equipment.
