Customised for you


Our expert team of Pacific Green marine engineers will discuss your fleet requirements and work closely with you to create a fully costed proposal for deployment with minimal impact.


Once we agreed the proposed approach, our global service team will survey your fleet, put together a plan and then meet your vessels in a port that suits you best. After that, our team will then design a custom scrubber solution for your ship and agree an installation location that will give you the best cost benefit and minimize the operation downtime of each ship based upon its trading pattern.


After overseeing the installation, the Pacific Green marine team will supervise the sea trails and class certification; we’ll manage this seamlessly, thanks to our unrivalled experience in this niche area. Shipowners can operate with peace of mind, in the secure knowledge that our dedicated global service team is on the case and available for any after-sales service.

Technical Overview

The ENVI-Marine™ process is a simple concept. First, it quenches the flue gases, then cleanses them by specialized frothing through pure seawater using our patented TurboHead™ process. Next, it polishes and releases them as harmless salts. ENVI-Marine™ Systems are fully flexible and can be designed as open loop, open loop closed ready and fully closed systems. For vessels running heavy fuel oil this system offers industry-leading ROI and will clean the exhaust to international emission standards now and beyond into the future.

ENVI-Marine Internal Components


Functions by:

  • Using the natural alkalinity of seawater to absorb SO2 emissions produced by marine engines
  • Post treatment discharge of neutralized sulphur into sea
  • Using caustic soda (NaOH) as a supplemental reagent when transiting areas with low seawater alkalinity

Flexible layout due to:

  • Patented horizontal head
  • Potential for component separation
  • Able to configure footprint to fit space available
  • Compact footprint due to efficiency


The ENVI-Marine™ system is designed to operate in either open or closed modes, depending on the emission discharge regulations for the waters in which the ship is located.

Open Mode – Single pass raw seawater, scrubber effluent returned to the sea.
Closed Mode – No overboard discharge permitted. Wash water is recirculated with NaOH added to neutralize sulphur. Solution is processed and contaminants are stored for disposal ashore.

TurboHead™ Technology

At the heart of our technologies lies the secret of the unique patented process which forms the basis of the ENVI-Marine™ and ENVI-Clean™ systems.

Technically, the company’s philosophy from the outset has been to build a device that provides the maximum possible molecular contact area between the harmful exhaust gases and the neutralising reagent. This allows the system to be smaller and more efficient, therefore more cost-effective in terms of both capital cost and operating cost for any given capacity.

Pacific Green Technologies has successfully achieved this by use of our specially designed foaming TurboHead™ that creates convection and turbulence in a unique way.

The patented scrubbing heads all have this unique reaction process, combining turbulence and circulation of the exhaust gas, maximising contact with the chosen reagent solution, be it plain seawater, limestone, or sodium-hydroxide solution.

The mandate throughout has been to fulfil the demands of our customers who want us to produce the most efficient emission control solutions in the most cost-effective way.

2020 Max

Marine heavy fuel oil is the most harmful transport fuel in use today and the shipping industry is by far the world’s biggest emitter of sulphur.

For this reason, the International Maritime Organisation (IMO) has adopted a global sulphur cap. This requires all ships to either use max 0.5% low sulphur fuel oil, or fit a scrubbing device capable of removing the sulphur to an equivalent level of MFO emissions or better from 1 January, 2020.

The Pacific Green Marine mission is to help ship owners, shipyards and naval architects build and retrofit the technology necessary to enable an easy switch to a low sulphur environment. This change means full compliance with the regulations, and equally importantly the fit will be done as quickly and conveniently as possible. The good news is that this change will enable HFO (Heavy Fuel Oil) as a fuel to be viable far into the future.

Nearly 90% of transport around the globe is by sea using HFO and as a consequence is responsible for releasing huge amounts of pollutants, mainly sulphur, into the Earth’s atmosphere.

As marine emission regulations bite harder in 2020 there will be major demand for marine scrubber technology around the world.

Many companies simply will not have the capacity to meet this demand. We believe this gives Pacific Green Marine the decisive advantage when it comes to converting both individual ships and larger fleets to a cleaner future thanks to our unrivalled capacity.
