Lessons learnt and improvements made

14

• Piping materials, especially open loop discharge pipe

• Material of exhaust gas pipe after the scrubber

• Sensors, gas analysers..• Level of automation• Droplet separation

(demister) to avoid extensive amounts of white smoke

• Cleaned water discharge fulfills MARPOL Annex VI

• Class approved system with required documentation

• SO2/CO2 ratio, PAH, PH and turbidity monitoring

• Tamper proof data logging, values saved every 4 minutes and stored during 18 months

Meeting the requirements
