Exhaust gas is washed by sea water inside the scrubber. The automation system is optimised during commissioning to the lowest possible power consumption, different operation conditions and to primarily maintain the exhaust emissions within the stipulated limits outside the ECAs and inside the ECAs (excluding zero discharge zone and US EPA). The wash water can be directly discharged in compliance with MEPC. 259(68) resolution requirements.

  No additives needed – seawater only

  Fewer byproducts and low power consumption

  Reduces Capital & Operational costs

   Easier to maintain

  ROI – 6 months to 1.5 years.

A hybrid system can run in both closed and open loop mode. Water is either recirculated in the system or discharged to sea.

Closed Loop Mode

In closed-loop mode, exhaust gases are washed with sea water mixed with caustic soda, inside the scrubber. The wash water is continuously recirculated by using a recirculation tank which is used to add NaOH and as a buffer. Therefore, closed-loop mode can enable zero discharge.

Scrubber system constantly measures the water and gas quality and it is always automatically controlled. Once the system is switched on, the scrubber runs automatically. The scrubber constantly self-adjusts to minimize energy and chemical consumption and control the process water in balance with SOx, pH, the concentration of PAH and turbidity level.

Open Loop Mode

In open-loop mode, the exhaust gas is washed by seawater inside the scrubber. The automation system is optimised during commissioning to the lowest possible power consumption, different operation conditions and to primarily maintain the exhaust emissions within the stipulated limits outside the ECAs and inside the ECAs (excluding zero discharge zone and US EPA). The wash water can be directly discharged in compliance with MEPC. 259(68) resolution requirements.

 Compliant in all waters

 Uses state of the art automation to offer easy switch between the  open and closed-loop operating modes

 Cost-effective on OPEX

The engine can be optimized to use a single fuel type.
