S-Keeper 7™ is a Continuous Emissions Monitoring System CEMS Type Approved for marine application fully engineered, integrated and validated in accordance with the applicable Directives. S-Keeper 7™ is made in Italy by Tecnova HT.
S-Keeper 7™ is in compliance with:
S-Keeper 7™ is fully tailored to the Shipowner’s requirements with particular focus on CaPex & OpEx balance.
S-Keeper 7™ is integrated with a modern PEM Propulsion Efficiency Monitor, thus encompassing metered Fuel Consumption, Fuel Oil Viscosity, Thrust and Torque measuring Systems.
Thanks to the specific engineering of this modular system, the S-Keeper 7™ installation is able to withstand the toughest marine environment.
On-board maintenance is easy even for an unskilled operator, while the SPMP Spare Parts Management Program ensures the traceability of every single component and its availability on the ship’s course.
