How do the fuels compare pro’s and cons? Which does the CE prefer?

I’ve worked in the wheel house on a few. The biggest thing is on DP if there is a sudden surge power is needed it will switch over to 100% diesel because the GVU’s cant keep up. All that needs to happen to go back to gas is a few buttons on the panel in the ECR. Also the constant bunkering is a pa…

Where will this project take place. I dont think there are any engines currently certified in the US/EPA for dual fuel so if it is a US built vessel/Jones act it will be difficult.

Your attachment is strictly LNG engines. Quite a few manufacturers have EPA compliant LNG engines. This thread asked specifically Dual Fuel. Globally there is dual fuel but as far as I know it on slow speed engines and none are EPA certified and thus my reason of asking where the project will take …

Well just to let you know Harvey Gulfs LNG vessels run on both liquid & gaseous fuels, diesel & LNG. I have an acquaintance that was an engineer on one of them. He said on long runs they could only stay on LNG for 1 leg of the trip & the other would be on diesel. I asked if they could load LNG offsh…

I just read through the press releases I could find on these vessels and all that I see are LNG fueled… A couple were upgraded to Hybrid propulsion with the use of GE batteries. nothing on the dual fuel LNG/Diesel as you described above I do not doubt that there was an EPA Exception granted for fie…

Again Those are likely helpful to original poster but not valid for sale in US.

[image] Seattle: I do not doubt that there was an EPA Exception granted for field follow type application, That would be crazy if they were only powered to run on LNG & nothing else. Since there’s only 1 LNG fueling station that I know of the vessels would have a range of a few hundred miles …
