Keeping Vessels Operational in UK & Global Waters

When wastewater systems fail – ships don’t sail

Operational delays are rarely caused by propulsion systems.

More often, vessels are held alongside due to failures in wastewater treatment or vacuum sanitation systems — creating compliance risk, operational disruption and unexpected cost.

Servac International supports ship owners, fleet managers and operators across the UK with specialist marine wastewater engineering, retrofit installation and lifecycle support.

Our focus is simple:
Keeping vessels compliant, operational and sailing on schedule.

“I have had occasion to work with Steve Hadnett (Servac MD) and found him both very helpful and extremely professional.”
