Carbon Intensity Reduction &
Energy Efficiency

With the IMO adopted energy efficiency strategy on the reduction of Greenhouse Gas emissions from international shipping, the following goals have been set:

  • Energy Efficiency requirements or existing vessels from 2023
  • Carbon Intensity targets for existing vessels from 2026
  • Reduction of carbon intensity by 40% by 2030
  • Reduction of carbon intensity by 70% by 2050 (50% total)

With this in mind, Avantis has recently bolstered our Energy Optimization Department, with the aim of actively providing support and assisting Ship Owners / Operators and Managers to achieve compliance with the new Efficiency Existing Ship Index (EEXI) Legislation, calculation of Carbon Intensity Indicator (CII) by investigating available / suitable decarbonization / Efficiency technologies and operation changes for their Vessels, ultimately providing the best solution in terms reduction of EEXI & CII and return on investment (ROI).

How Avantis Help Achieve EEXI Compliance.

After numerous discussions with Clients and efficiency solution technology providers, we have developed a three (3) phase “Smart Engineering Approach”, with the aim of providing an independent study of the effected vessels, by utilizing our in house engineers and extensive data base gathered through non-exclusive agreements with the leading technology providers, to the end goal of integration of the best preforming system, dependent on vessel type onboard. Our “Smart Approach” allows us to provide a fast-track solution for the immediate assessment of the current EEXI & CII and an initial high level study evaluating available fuel consumption reduction & decarbonization solutions for the vessel(s) in question. Details regarding our proposed approach are shown in the following tabs:

Phase 1 - EEXI / CII Calculation & Decarbonization High Level Feasibility Study
Phase 2 – Selection of Chosen Solutions, Engineering Works and Integration.
Phase 3 - Engineering, Design and Integration
Phase 1 - EEXI / CII Calculation & Decarbonization High Level Feasibility Study

This includes:

a) – Current EEXI & CII calculations

b) – Assessment of potential operational changes and / or energy efficiency technologies best suited for the vessel to achieve optimal energy optimization / decarbonization, whilst providing an attractive ROI.

i. Potential operational changes range from:

    1. Speed reduction
    2. Vessel Sailing Route Assessments to determine consequential optimization.
    3. Existing system / equipment evaluations, upgrades, or power consumption reductions
    4. Cargo Handling System evaluations, upgrades, or power consumption reductions
    5. SW Pump evaluations, upgrades, or power consumption reductions
    6. VFD installation Evaluation
    7. Smart HVAC


ii.
Energy efficiency technologies currently included in evaluation providing high level potential savings

    1. Air Lubrication Systems
    2. Wind Assisted Propulsion (Flettner Rotors, Kite and Sail Propulsion, etc…)
    3. Marine Battery Systems / Energy Storage
    4. Waste Heat / Energy Recovery
    5. Exhaust Gas Cleaning Systems
    6. Efficiency Propellor retrofit
    7. Efficiency Rudder Retrofit
    8. Existing System / equipment auxiliary saving technologies
    9. Shaft Generators
    10. Engine Tuning
    11. Trim Optimization
    12. Coating / Antifoul evaluation
    13. Cold Ironing
    14. HVAC Optimization
    15. Insulation improvements


c)
– Providing a high level report detailing the above.

Phase 2 – Selection of Chosen Solutions, Engineering Works and Integration.

This includes:

  1. Detailed calculations on energy / fuel saved, ROI, based on chosen method of efficiency gains
  2. Assessment of potential paired technologies to provide higher efficiency / fuel savings.
  3. Detailed operating analysis
  4. Operating environmental analysis.
  5. Desktop Efficiency Survey
  6. Assessment of Engine Tuning
  7. Assessment of Fuel Consumption
  8. Organic Rankine Cycle
  9. Accurate calculation of improved EEXI ratings
  10. Hydrodynamic evaluation (dependent on selected solution)
  11. A detailed report detailing the above
  12. High Level Fleet Analysis
Phase 3 - Engineering, Design and Integration

This includes:

  1. Vessel Survey & 3D Scanning (if required)
  2. Basic Design
  3. Classification Society Approval
  4. Detailed Engineering & Design
  5. Integration of chosen system on a global scale.


i.
Turn-key installation (Equipment Supply & Installation either in service or in Shipyard) allowing for single point of contact

ii. “Shipyard Ready” approach, where partial scopes are completed in-service, allowing for reduced time/costs within the Shipyard.

iii. Commissioning assistance

iv. Shipyard Supervision
