Environmental Services
Our broad portfolio of environmental products and services is geared towards providing solutions for today’s environmental challenges. Particular emphasis lies on optimizing lifecycle efficiency, minimizing environmental impact by reducing air and water emissions, and minimizing waste volumes from both land-based power plants and ship installations.
Oily Water Separation System
We offer a complete Wärtsilä SENITEC oily water separation system for land and marine based applications. Together with a design that can handle today’s tough conditions in the marine or land based environment, we can offer a complete installation, commissioning, maintenance and training program.
Retrofitting of complete units on existing installations is possible without interrupting operations.
YOUR BENEFITS
SENITEC M- and P- Series are approved according to IMO solution MPEC 107(49) and the US Coast guard according to the US 46 CRF 162.050. The units can be operated on low maintenance/operation costs, high capacity with low space requirements and the summarized advantages below:
• Reduces sludge/bilge disposal need
• Smaller harbour fees and less maintenance
• Fouling of sludge tank can be avoided by separating discharges of solids
• Works in low and high temperature ranges
• Can handle 0 -100% oil
• Not sensitive to soot or cleaning chemicals
• Fully stainless steel housing - long lasting quality
Today, the SENITEC M- and P-Series are the most complete sludge and bilge treatment units on the market.

Selective Catalytic Reduction(SCR)/Scrubber
We provide an optimized solution for the latest emission regulations, evaluate your vessels/plants/installations and select the appropriate equipment size. We offer installation, commissioning, test running, maintenance and spare parts.
YOUR BENEFITS
SOx-scrubbing is the most economical way to comply with IMO regulations regarding SOx (Regulation 14). In SOx Emission Control Areas the savings to costs is immediate.
Wärtsilä fresh water scrubber solutions are fit for new buildings and retrofits, for any engine and boiler brand. WÄRTSILÄ NOR(Nitrogen Oxide Reducer) is based on selective catalytic reduction technology. The NOR portfolio covers Wärtsilä’s medium-speed engine portfolio mainly for marine applications. The size of the NOR is optimized in terms of modularity, performance and costs. NOx emissions are reduced up to 90%.

Ballast Water Treatment(BWT)
BWT systems are able to be installed during the sailing without interfering with the ship’s schedule and onboard daily operation.
We can inspect vessels and provide recommendations for optimized installations. We provide a total service package, such as pipe work, installation of the unit, welding, electrical installation, commissioning and crew training on site.
YOUR BENEFITS
The system is purpose-built and optimized for the treatment of ballast water, with all active components fitted within the same housing. This allows for an easy installation, and since both treatment process steps are handled in a single unit, it offers a high degree of predictability for any pressure drops.
No extra pipes are required to join the two treatment units, which mean no additional pressure losses.

Emission Measurements
A multihole sampling probe is inserted into the exhaust manifold to measure gas concentration.
The exhaust gas sample is extracted via a heated filter and a heated sampling line into the conditioning unit where the humidity is removed. From there the concentrations of the individual exhaust components; Nox, SOx, CO, CO2 and O2 are measured by the portable analyzer HORIBA PG-250.
The analyzer is calibrated before and after the measurements with zero and span calibration gases corresponding to the measured ranges.
Typically the emissions are measured on 25%, 50%, 75% and 100% engine load steps.
A detailed report with the measuring results and description of the measuring procedure is issued after each measurement.
YOUR BENEFITS
• Verification of compliance with applicable emission legislations after modifications, upgrades and legislation changes.
• Emission measurements also support engine condition and performance checks.
OUR SERVICES
Measurement of Emission according to IMO Technical NOx code 2008 ANNEX VI Simplified on-board verification.
Measuring equipment and measuring procedures fulfil the IMO and Class Requirements for amendments of the technical file in case of Tier I / II upgrades, changes of engine tuning or changes of IMO controlled components.
Emission concentration measuring ranges:
- Nitrogen Oxides (NOx) up to 2’500 ppm
- Sulphur Oxides (SOx) up to 3’000 ppm
- Carbon Dioxide (CO2) up to 20% vol
- Carbon Monoxide (CO) up to 5’000 ppm
- Oxygen (O2) up to 25% vol
In case a continuous emission monitoring is required, Wärtsilä can offer the Continuous Emission Monitoring System(CEMS) with full reporting capabilities in accordance with customer/authority requirements. Alternatively, a simpler analyzer/feedback system (e.g. after treatment systems) can be offered.
