The methanol conversion project - summary The world s first pilot project to convert a ship to methanol-diesel operation (DF) 2013 - Suitable vessel/route identified EU support granted 2014 - Development/test of conversion kit by Wärtsilä Supply agreement with Methanex Risk analyses in the Ports of Kiel and Gothenburg Rules in place for IMO IGF code and Class (LR & DnV) 2015 - Q1 shipyard conversion at Remontowa Bunkering station built on quayside in Gothenburg 2015/16 - Engines convert to methanol one at a time Big interest and recognition from marine industry Built 2001 in Spain Length 240 m Breadth 28,7 m Draught 6,15 m Cargo Capacity 4 000 lane meters Passenger capacity 1 300 Main engines 4 x Wärtsila 8ZAL40S, 6000 kw Conversion budget (ship) > 11 million
Pilot vessel - Stena Germanica Built 2001 at Astilleros Espanoles (AESA), Puerto Real LOA 240 m Beam 29 m Draft 6,1 m Crew 50 70 pax Capacity 1,300 pax 4,000 lane meters Swedish flag Heightened at Remontowa Shipyard, Gdansk 2010 Four Wärtsilä-Sulzer main engines 23,000 kw 3+1+1 auxiliary engines 2 x Controllable pitch propellers Extended 52 meters in Lloyd Werft, Bremerhaven 2007 3 x bow thrusters Kiel Gothenburg, 13 hour passage 21 knots steaming 365 trips/year
After testing in Trieste, conversion of the main propulsion machinery, 4 x Wärtsilä 8ZAL40S (totally 24.000 kw) was done at Remontowa shipyard in Gdansk during Feb/March 2015
Stena Germanica upgrade at Remontowa Bunkering system + New bunkering facility on quay Upgraded engine control system and eight dual diesel/methanol injectors per engine (Wärtsilä development) SOLAS alternative design with risk analyses by Lloyds Inert Gas System with two generators and nitrogen tank New high pressure common rail system Upgrading of fire alarm system Safety and fire education for safety crew Engine room Pump room Fuel tank Flame and gas detectors in engine room Four additional (high pressure) fuel pumps installed - and electrical switchboard room. Separate ventilation system in pump room with airlock. New sensors for leakage New double walled piping between pump room and engine (60 m) Ballast tank in double bottom converted to 500 cbm zink coated methanol fuel tank with IGS
Engine before and after conversion
Technology: Test results NOx 3-5 g/kwh (Low Tier II, no major conversion) CO (< 1 g/kwh) THC (< 1 g/kwh) PM only from MGO pilot (FSN ~ 0,1) SOx only from MGO pilot (99% reduction) Formaldehyde emissions (~ below TA-luft) No Formic acid detected in exhaust gases No reduction in output and load response unchanged, full fuel redundancy Higher efficiency (tests shows lower fuel consumption in methanol mode) Methanol or diesel can be selected (or re-selected) as source of energy in a fast and reliable way without stopping the engines and without losses in engine speed and output.
METHANOL as marine fuel Potential Challenges SOx & NOx less 90% and NOx less 60% in emissions Easy to handle (liquid) with efficient infrastructure Large commodity Feedstock is natural gas (LNG) Green methanol development (Bio- and CO2 captured methanol) leading towards zero vision Low flashpoint and viscosity Corrosive Volume/low energy content (half compared with oil) Regular bunker currently price competitive Fossil Cost

Methanol lessons learned so far Conversion project requires very detailed planning as there is no roadmap. Shipyard conversion went according to plan but planning a ship design from scratch is easier. Approving a new fuel has taken long The ship has had a couple of incidents adjusting the safety and injection valves to the fuel pressure. Important for ships crew to be motivated as it is work intense. Difficult to predict energy prices. We are satisfied so far a technically sustainable alternative over time.
