• All five vessels trading in the Baltic and North Sea area• How to tackle the Sulphur limits?
Langh companies employ about 160 people. We are an efficient flat organisation where people do long careers!
Case on installing and developing scrubbers
• Originally developed as a closed loop system• Prototype testing summer 2012 • First full scale installation in May 2013• Open loop possibility added end of 2013• Four hybrid installations during summer 2014

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
