They have built a new one, bigger and even more fuel and emissions efficient, with greater capabilities.  Why don't more companies go this route?

 

BioMar: Norwegian production expansion comes on stream

03-Nov-2017 By Lynda Searby

Danish fish feed producer BioMar has expanded production capacity by 140,000 metric tons at its Karmøy facility in Norway and invested in a “new generation” LNG vessel to transport feed from the factory.

Oops, I tell a lie! Just checked bunker price. $400/tonne which works out at $60/barrel. Unbelievable. It is waste product from oil refining so should be much cheaper than refined diesel. No wonder NG is being considered!

Not in this Reality, you're not. A metric ton is equivalent to about 7 bbls of oil. There's no way to get to your $2/bbl in this century. Sure, when WTI sells for $10/bbl bunker is that cheap, but I wouldn't build a business plan on that. 

The real problem with LNG fuel is its size and complexity. Size is premium on a container ship and their crews are not what I would call summa cum laude material. Add in the "filling station" problem and implementation gets tricky indeed. I'm 100% in favor when the ship in question is an LNG transport. Nothing like hauling your own fuel.

Yeah, I already saw my own miscalculation. But I can see how the operators of the largest container ships might like the idea of "dual-fuel" given the ability to switch the mix depending on price. I guess the refinery waste is used to produce both bunker fuel and bitumen to make asphalt roads, but I do wonder the effects that electric vehicles would have on supply and demand. If there were less oil refineries in the future, I guess there would be less bunker fuel produced? On the other hand, a rapid decline in demand for bunker fuel due to more gas-powered ships may cause the price to decline? The ship operators would become "price-makers" as opposed to price takers? The other thing I like about Ron's suggestion is that dual-fuel ships should also be able to take 20% green H2. Flipside is that without all that SO2 in the atmosphere, the planet will warm even faster. There is always a trade-off.

The price of asphalt has been climbing steadily since 2000, which is when we began to see a critical mass of delayed cokers installed in refineries. Now they have added FCC units and hydrogenation using various means, which means they can "recycle" the bottoms and produce more profit from "free" feedstocks. They've no reason to "dump" the bottoms anymore. Add in the sulfur ban and bunker fuel is going the way of the dodo bird. Already ships are moving to diesel at the lowest quality they can find. They might be wise to dump all their used cooking oil into the tanks while they're at it.

If you really did have your eyes open, you would know that the only way to reduce global warming is to make it economically viable to do so. China and India will not switch away from FF's unless economically sensible and neither will the West. As I said earlier, that is precisely what is beginning to happen, solar and wind already cheapest way to produce electricity, just need cheap storage. Green H2 is also on it's way, and experiments already being done with H2 powered aircraft. May never be suitable for long-haul flights, which is why I still see the oil & gas industry surviving another 2 centuries, albeit much smaller than today. Then again, bio-fuels may be cheaper than methanol within 30 years?

Oh Hi my eyes are somewhat open...Smiles while I am not a rocket scientist by any means I can assure you I have somewhat of a grasp on trade and economics. 

Let's play a game...no more trade with China or India until they go LNG...Meanwhile the US will pickup a few hundred thousand  jobs ...and world wide pollution will drop. 

Actually I do believe mfg and shipping costs from China and India is now the same as just mfg in the US

You just reminded me. Saw a part of Australian "Landline" show a few weeks back, CSIRO has found a plant that (when genetically modified), can produce oil even cheaper than palm oil. It might displace palm oil and perhaps be used as a bio-diesel. Can be grown in arid conditions apparently. There is so much research going on into greener production of virtually everything that it impossible to keep track of. The Japanese have even worked out how to make hard plastics out of limestone and soft bio-degradable plastics from some type of natural fibre. Yet the world is investing heavily in petro-chemicals?!?

What you re thinking of as "bunker" is actually a refined fuel.  In the old days, bunker was broken into two types:  IFO 180 and HFO 380.   IFO for intermediate fuel oil, and HFO for Heavy fuel oil.  Now, those are products that are from the bottom of the refinery splitters, what is left over in still-liquid form when the middle distillates are taken out.  So in the "old days" thaat stuff was sold to the ship industry and burned off in those monster diesels that were specifically designed for that grade of fuel.  And it was very cheap - below 6 cents a gallon, at one point. 

Once the IMO demanded that all ships go to low-sulfur fuels on January 1, 2020, the ship industry largely demanded that the refining of the grades of bunker be carried out by the fuels suppliers, not done on board by aftermarket treatments to keep the sulfur out of the exhaust.  And the fuels industry has largely responded, so what you are seeing as quoted as "bunker" is the heavy stuff but with the material purified.  And that is why you are seeing those $400/tonne cost figures.   

Can you still buy the old crud?  Nope.  Off the market.  Now it is either marine diesel, or refined and treated bunker. 

On another note, the reason you do not see many ships powered by natural gas is that of energy density.  A big ship's diesel running on gas produces considerably less power than one on oil fuel, so the same engine gets less horsepower, and thus steams much slower.  It will also run colder, causing internal engine problems.  And you need to store all that gas, which is yet another problem.  It is not as easy as you might think; lots of technical issues.

It appears that that ship is not built with a diesel.  The engine is apparently a Rolls Royce jet engine, a turbine, set up to burn gas instead of kerosine.  It is also a local-range ship, going from some port out to where the fish farms are, which are typically in sheltered waters in the fjords.  The fish are not out in the open sea.  The Danes are under great political pressure to "go green," for example to the extent that Danish coal electric plants are pressured to burn dried olive skins and twigs, compressed into bricks, instead of coal.  They buy the bricks in Spain and haul them all the way to Denmark, in order to satisfy the Greens.   Does the fish-farm boat make the grade cost-wise?  I dunno, and would not speculate, but cost is not the only criterion.  Politics also is.

A very key point is also the refuelling infrastructure... 

LNG as shipping fuel is very much in a chicken and egg place at the moment.

The fish is in Norway, not Denmark. You avoid some air pollution taxes when you go LNG. Also, energy density is not that important for this type of work as there are limits to how small the vessel can built and fish feed is more about volume than weigth.

OMG Jan what have you said??

Ron is gonna be soooo pissed at you!!

All good points though.

I do believe that generally 70% of ships power comes from their turbos so either make these more efficient or more plentiful and that may solve the power issue. The other points still stand though

Agree. I have degrees in Physics, Environmental Science and Business and could refute half of that twit's points but it not worth it. I am a "hard-core" greenie, but I have always known that nuclear power is part of the answer. As for solar, it would only take 8 sites and 0.1% of land mass to power the planet. He didn't know what he was talking about when he was young, doesn't know what he talking about now. Never studied science yet thinks he is such a master at it that his meta-analysis better than mine? He just goes from one guilt trip to another because he will never be able to see the bigger picture. Good thing wind and solar now cheaper than FF's and H2 economy is on it's way. Nobody needs him or his replacement (Greta) anymore. Business is getting on with the job of creating cleaner, cheaper, sustainable, and more secure energy systems. Everybody needs to just get over it.

Natural gas is the answer. It is less expensive and more abundant than any other energy source. It is very clean and quick to set up. It does not blight the landscape and create the toxic waste that solar does or the fiberglass that has to be buried. A lot of waste streams can be made into biogas creating a dual benefit of eliminating waste while creating green energy. 

Nuclear cannot compete on a cost benefit ratio over the lifespan especially since they are still leaving their antiquated plants standing and they are being subsidized by the end consumers who have to pay higher energy prices. Worst yet, they have not yet found a safe way to store their nuclear waste for thousands of years. Add to that, the American people do not want them anymore because they never delivered the cheap energy they promised back during President Eisenhower's terms.

Hydrogen is expensive to produce and difficult to transport. It has not proven itself in any substantial way.

The shipping companies do not want to make the expensive conversions. The smokestack scrubber companies try to discourage it and sell them scrubbers. 

I really haven't followed it very closely lately because It is a slow growth. I think that extremely low natural gas prices will help since I expect low grade diesel prices to rise. 

Conversions of ships are expensive but NEW SHIPS being built should be mandated to go with natural gas. Refueling is not a major problem. A lot of facilities have already been built and refueling ships could also be used as long as needed. 

I will try to get more shipbuilding information.

I think that is a small LNG ship compared to the container carrier ships being built, but good technology is being used. This is not rocket science. Natural gas has been used in ICE engines since WW1.
