Waarom LNG? Waarom DF technologie?
Respect en zorg voor natuur is een DEME core value Oprechte interesse in technologie die schadelijke uitstoot verkleint
De vermindering van de uitstoot door met aardgas te werken ipv diesel olie is Aanzienlijk:
CO2 - Approx 25%SOx - Approx 80%NOx - Approx 80%PM Almost eliminated
21
(MARPOL annex vi) emission regulations in (S)ECA’s trigger action.Waarom LNG? Waarom DF technologie?
SOx emissions NOx emissions

Source: P Semolinos, “LNG as bunker fuel: challenges to be overcome”, Total gas & Power
DEME beschouwt LNG als een future-proof & duurzame oplossing
Waarom LNG? Waarom DF technologie?
23
WaaromLNG?High Capex but low Opex
Source: DNV-GL, 2011
who can predict fuel prices?delta is what it’s all about!
24
Dual Fuel omdat:
LNG supply chain verre van matuur.Indien geen LNG beschikbaar werk op diesel.Elimineert “LNG supply risk”
LNG tank grootte en dus actie radius gelimiteerd om business case gezond te houden. Bij oversteek: MGO als “range/autonomy extender”
Waarom LNG? Waarom DF technologie?

LNG tanks - challengesSize, for comparable energy content
1178m³* Box in which the tank + insulation + saddle fits
A 630m³ LNG tank contains a heat value of:= approx 630m³ x 0,95 x 22GJ/m³ = 13.167,- GJ
The box shape equivalent bunker tank filled with MGO (DMA ISO 8217 contains:
= approx 1178m³ x 0,95 x 35GJ/m³ = 39,169,- GJ On board, LNG requires approx 3 times more space than MGO

LNG tanks - challenges
Price of LNG tanks are ....crippling: Market feedback for C type tanks
Advantage for single walled tanks. But only viable for larger volumes.
Approx size type Approx price75m³ Double walled 13k EUR/m³200m³ Double walled 10k EUR/m3600m³ Single walled 3,5k EUR/m³

Bunkering
LNG bunker infrastructure is developing, especially in SECA but still in infant stage. Chicken –Egg problem. Gas fuelled fleet now expanding rapidly, also outside Norway. Critical mass attained?
AGA’s “SeaGas” LNG barge moored to “Viking Grace”
28
LNG BunkeringMooring-Imperative to limit movement during bunkering!Different bunker locations. Different mooring configurations. Bunker station on both sides?
Bunker connection - size of filling line?2”? 4”? 6”? 8”?50m³/h 200m³/h 400m³/h 800m³/hBunker barges: “2” max 50m³/hr. Too slow......”
Vapour return lines? Standaarden?
Bunker freqentie? Mix van LNG & MGO?
29
LNG als brandstof – consequenties
1) Investering & return
2) Bunkeren: zie voorgaande slides
3) Veiligheid aan boord – hazardous zones
4) Crew training & qualifications & staff training
Problem: no well established rules with most flag states
........can also be considered as an opportunity.
5) Insurance: DEME’s underwriters: no issue.
Overgang wind naar kolen & stoom| naar olie| naar gas
Multi-disciplinaire aanpak is vereist t.b.v. vlotte overgang.
