ECOLOGICAL FOCAL POINTS

1. Water

Protection of the marine ecosystems:

  • Zero harmful discharge of wastewater.
  • No transportation of foreign invading species.
  • Antifouling hull paint without biocide.

Optimization of water management:

  • Water consumption reduction.

Solutions:

  • Advanced wastewater purification systems including half-Alaska-Murkowski performances and nutrients removal.
  • Reuse of AC condensate.
  • Wastewater recycling: advanced treatment and recycling as technical purpose for machinery equipment, gas treatment, deck washing and laundry.
  • Biodegradable lubrication oil and seawater lubrication.
  • Ballast water treatment systems.
  • Silicone hull anti-fouling system.

2. Waste

Challenges:

  • Lowest emissions to sea and air.
  • Operational improvements by flexible and cost effective solutions.
  • Valorization of the waste into energy.

Solutions:

  • Briquetting machine for high recycling ratio, potential valorization on land and storage space optimization.
  • Flue gas cleaning systems.
  • Energy recovery systems.

3. Energy

Challenges:

Improvements for fuel cost reduction:

  • Reduce the consumption of the final consumers.
  • Improve the efficiency ratio of the energy conversion.
  • Alternative energy assistance (wind, solar, ...).

Solutions:

  • Simulation tools to optimize the design of the ship to her foreseen operational profile.
  • Optimized hull and appendages with the best hydrodynamics parameters matching the ship program.
  • High efficiency electrical propulsion.
  • Advanced heat recovery systems on diesel engines and thermal waste treatment plant.
  • Optimization of the electrical load with efficient HVAC systems, low consumption lightning, speed drives, high efficient pumps.
  • Further improvements can be achieved by adapted platform and technical solutions package to the operational profile.

4. Emissions

Challenges:

  • Ecorizon Air Emission Management project is targeting to reduce ship impact on global warming and air quality. Air emission from a ship is coming from exhaust gases of power plant, oil fired boilers and waste incinerators.
  • Combustion of fuel oil leads to emission of CO2, a green house gas. We need to focus our efforts on energy management improvements to reduce CO2 emission.
  • Air quality is affected by the emission of NOx, SOx and particulates. Together with our suppliers, we are working on combustion parameters and post-treatment systems.
  • Ecorizon is keeping ahead of the regulations by proposing to integrate a package of cutting edge solutions.

Solutions:

  • Multi-parameters online emission monitoring system, linked with GPS position.
  • Energy savings features including efficient propulsion architecture, energy recovery systems and consumers' optimization to cut CO2 emissions.
  • Best diesel manufacturers technology including diesel engines optimized combustion devices reducing significantly particulates emissions and visible smoke, and reducing NOx emission from 20 to 40 %. Higher level of nitrogen oxides abatement can be reached with Selective Catalytic Reduction (SCR).
  • Exhaust gas control systems as scrubbers to reduce the SOx level, giving flexibility in fuel selection even in SOx emission controlled areas.
  • New generation of waste treatment systems and alternatives to incinerators.
  • Odor treatment system for ventilation line coming from liquid and wet waste systems.

5. Sustainability

Challenges:

  • Ecorizon sustainable design project aims to take environment into account from the design phase.
  • Together with environmental specialists, Ecorizon sustainable design project develops tools to assess the environmental impacts of the ship from construction and operation to recycling.

Solutions:

  • Green passport: an inventory of all potentially hazardous materials in the ship structure and equipment, describing the respective locations and quantity. This green passport will facilitate ship recycling.
  • Environmental impact assessment: give ship owners a real view of the environmental impact of the ship by using a recognized tool with a multi criteria approach including global warming, air quality and non-sustainable resources consumption.
