Sternguard IWSS

The Wartsila Sternguard In-Water Serviceable Seal (IWSS) is a fully underwater serviceable seal. This provides segments including commercial, cruise & ferry, merchant and in-land waterway vessels with opportunities to reduce down-time as there is no requirements for dry-docking, habitat usage and shaft withdrawal.

This reduces costs as there is no requirement to drain the stern tube oil or aid and transfer vessels to a dry dock slot. In addition, there is no need to unload cargo for an underwater overhaul.

The Sternguard IWSS has been designed to provide a reliable and faster service as well as improved operational performance. Environmentally Acceptable Lubricants (EALs) and mineral oil lubricant are accepted and the seal is compliant with the 2013 US EPA Vessel General Permit rules.*

To enhance serviceability, the seal is equipped with an inflatable seal which eliminates the need for draining the whole stern tube during overhaul. In addition, the inflatable seal minimises the possibility of leakage of lubricant to the environment during in water service.
