The business case for installing an EGCS

Options for compliance with regulations:1. Switch to distillate (MGO) – pay the extra fuel bill 2. Install EGCS – continue operation on HFO3. Switch to other fuel types (LNG or LPG) – limited supply

Optimal choice depend on:4. How much the vessel will be trading in ECA5. The power (MW) and fuel consumption of the vessel6. Assumed price difference between MGO and HFO

Example:10MW vessel trading in ECA and USD 300 fuel spread gives fuel cost = USD 3,4 mill./yearEGCS price: USD 2,6 mill + Installation cost USD 0,8 mill = USD 3,4 mill.

Rules, Certification, Limits

• Rules and regulations: IMO Guideline, Class Guidelines, Regional/Local regulations (EU directive, VGP US)

• Certification: Scheme A or Scheme B (monitoring)• Monitoring:

– SO2/CO2 (97-98 % reduction required)– pH (6,5 at 4m from outlet, 6 at outlet suggested by VGP) – Turbidity (Diff In/Out 25 FNU)– PAHphenantrene equiv. (Pending amount of water per MW)
