Increasing number of operative greener tugs
Towards more sustainable harbour towage industry
FUTURE CHALLENGES
FUTURE CHALLENGES
REGULATORY
• IMO
• EU
• NATIONAL
• LOCAL
CLIENT REQUIREMENTS
• SAFE & EFFICIENT
• COMPETITIVE PRICING
• ENVIRONMENTALLYFRIENDLY
LIFECYCLE OF A TUG
• Design that lasts for 40-60 years
• Investments
• Operational costs
• Modifications
• Operations in different countries
• Responsible recycling
SOURCES OF ENERGY IN THE FUTURE
Alternative fuels
Batteries
Nuclear energy
Solar power
Wind energy
Energy efficient use of tugs
Use of shore power
Sustainable production, use and recycling
ENVIRONMENTAL FOOTPRINT
GREEN DEVELOPMENTS HYBRID & TIER III
READY FORTHE FUTURE
HYBRID
RT Emotion
RT Evolution
2012: 1st Generation hybrid
RT Adriaan / nowadays VB Kracht
HYBRID TUGS - generations
2015: 2nd Generation hybrid:Series Advanced Rotortugs ART80-32
IMPROVED FUEL ECONOMY
REDUCED EMISSIONS OF CO2, NOX AND PM
Lower fuel usageCleaner combustion
SAFE & HEALTHY WORKPLACE
MAINTENANCE SAVINGS
BENEFITS HYBRID
NOISE REDUCTION
Clean & Simple
CO2
Emission element % reduction(overall)
Reduction per year (kg)
PM (particulate matter) ~ 35% 532
HC (unburned hydrocarbons) ~ 36% 198
NOX (nitrogen oxide**) ~ 32% 21.600
CO2 ~ 35% 443.000
(Emissions per tug: 2nd generation Rotortug ART80-32)
LESSONS LEARNED HYBRID SYSTEM
Training program and skills crew (Master & Engineer) Clear instruction for Dispatch (planning & mobilization hybrid tugs)
Battery's location & safety precautions batteries
Maintenance cost hybrid system & battery life cycle
Possible black-out issue hybrid modus 1st generation. Improvements / update software (achieved)
Seeking best match between port environment (locks), tug capacity & hybrid system
IMO TIER III
2021: 4 newbuild tugs TIER III in Zeebrugge
IMO TIER III - FLEET
VB Samba and VB Flandes (ART 80-32)
VB Bolero and VB Rumba (ASD 2813 )
2020 & 2021: 1st and 2nd retrofit conventional tug
Union Koala
Union Panda
“Putting an elephant in a shoe box”
• Engineering of the routing in engine room for the new exhaust system
To avoid clashes with the existing equipment and piping)
• Installation SCR (Selective Catalytic Reduction) system
Per engine one after-treatment unit: a 4m length and 1 m width, and a weight per unit of approx. 2 tonnes
PIONEERING PHASE IMO TIER III Union Koala & Union Panda
IMO TIER III – RETROFITUnion Koala & Union Panda
ABC engines connected with Selective CatalyticReduction units
BENEFITS IMO TIER III
IMO TIER III CERTIFICATION
REDUCED EMISSIONS OF NOXCleaner combustion contributes to reducing exhaust emissions thanks to TIER III and the use of sulphur free fuel oil - type EN590
NOX
Emissions reduction of NOx per tug:
Emissions reduction of NOx on a yearlybasis, for the entire fleet of 6 tugs operating in Zeebrugge, all complying to TIER III:
353 tonnes
80%
12 x
30 tonnes
LESSONS LEARNED IMO TIER III
• Retrofitting a tug to reduce NOx emissions is possible with minimum operational impact
• Retrofit 2nd tug ‘Union Panda’ ready within 3 weeks
• Significant additional value TIER III-tugs
• Retrofitting a tug to reduce the CO2 emissions is impossible without major changes
• Investment is for the ship owner:No climate contribution paid by the customer or (port) authority for the use of these tugs and ecological footprint
