In the early 1980's I had several trips where the ship would 'slow steam' . Yes it reduced the fuel bill, and emissions, but it could also increase the crews tip time dramatically. Most trips were on a 6 month basis with the company I worked for but one was exteneded to 9 months purely waiting for the retail price of the cargo to go up. It gets very boring and you end up looking for things to paint!!. We had a very spruce ship by the time we hit port again and could 'pay-off'. my Fiance was very understanding as We had to change the wedding date 3 times.

Rigging and sails isn’t cheap. And the challenge would be skippers and crew will need to retrain to understand apparent wind and use of sails - bringing back the master of sails. If it is blowing 45 knots, a modern large ship is going to be fine assuming the sea states aren’t insane. Put a rig on it and suddenly even without sails the windage will risk capsizing the ship.

@MervynPartin 3 жыл бұрын

Most of the vessels upon which I served were designed for higher speeds (eg 17 knots) but were generally run at around 14 knots. Exhaust gas boilers were fitted that could supply sufficient steam to run a turbo-alternator that would cover the entire ship's electrical load at sea. On slow steaming, there was insufficient steam generation so the shortfall had to be made up with a diesel alternator at part load- not ideal for diesel engines. Just another problem down to slow steaming. Some diesels were prone to design faults leading to frequent and sudden failures. In deep sea, clear of all traffic, a blackout could be avoided by increasing main engine speed to generate more steam from the exhaust gas boiler for the turbo-generator, until another diesel (if available) could be started.

@tjampman 4 жыл бұрын

Well, Labour costs are pennies compared to the fuel costs. A large container vessel going full service speed abt 20knts will consume about 250tons/day of fuel oil, at a price 400$/tons, that is 100.000 $/day. Labour cost, I dont really know, but lets say an average ship is crewed by 20 people earning 5.000$/month average, thats 100.000$ a month. (I think this avg. salary is too high) So if they can half the consumption of fuel, by going 5knts slower, that would easily pay for itself.

True; It is like driving a Car. When going way more than 130km/h you will get diminishing returns and if you go less then about 90/100 you will take longer than the fuel cost is worth so people remember: neither go too slow nor too fast. There is an optimal speed and it is probably whats set by the speed limit. No need to arrest people who go a little too fast or too slow though;)

Excellent content. I’m an airline pilot and the parallels are dramatic. Airplanes are designed for an optimum speed which varies somewhat with the cost of fuel, crews, and maintenance. We generally can go a bit faster to make up time but fuel flow goes up exponentially which could make an otherwise profitable flight lose money. For long range flights we likewise can have scheduling conundrums: you can sometimes buy two aircraft that can barely cover a route at high speed but have much higher per aircraft and fuel costs, or you can do it a bit slower with much less cost per flight (or per seat-mile) but you’ll need three aircraft to cover the route. Given that widebody airliners can cost upwards of $200 million each on the high end, this can obviously make a given route unviable economically.

A few years back we used slow steaming to save on fuel costs, however, most engines are designed to run at optimum rpm for proper piston ring sealing, combustion etc. the liner wear lifetime was greatly reduced, we fitted Teflon tubes ion the cooling water bores in combustion areas to raise the liner temperature (cold corrosion was another factor) So the trade off with fuel cost vs slow steaming was not that simple. Also, adding on days due to slow steaming would increase maintenance, crew costs insurance cost. Give me an engine at rated peak performance any day, they humm where as SSteaming they rattle and shake.

I can't believe I clicked on this. I first went to sea in 1973, joined big oil tankers in 1977, retired in 2016. I remember leaving Ras Tanura around the Cape to go to Savona at 30 RPM on a 264,000 ton VLCC. Chuck an empty beer can over the side and you would see it for ages. At such low speeds there was no bleed steam from the turbines, so the auxiliary systems needed live steam, pushing up bunker costs. Once The Company realized this, we moved faster, but went to almost shutdown at the destination. More time for fishing - and at Freeport, Bahamas, we made lobster pots - oh yes!

Really interesting video. Funnily enough, the big three Japanese companies NYK Line, Mitsui OSK Lines and K-Line have formed a consortium called ONE (Ocean Network Express) to deal with the capacity issue on boxships that you were describing. You can see one of ONE's bright pink containers on the NYK Line vessel at 5:40. Sort of like international flights - there really has to be a move towards increasing the 'load factor' for these companies to weather the storm. COVID has caused a real crisis for containership owners. Charter rates have taken a major hit, and it is broadly considered that there is going to be record amounts of scrappage in the coming months and years. That's another thing to factor in on the environmental side as ship-breaking still remains a deeply troubling business. Another major factor is IMO 2020 and low-sulphur fuels. An environmental plus, but undoubtedly a challenge for shipowners. The global fleet has never been bigger, there's an oversupply of vessels, and we're going through the biggest demand shock in a century. Going to be an interesting few years!

No, that would be far too slow. Regardless of economic conditions, shipping companies need to balance the pros associated with slower speeds with their cons: while they'd save fuel at slower speeds, they'd also get paid less per ton-mile, have a harder time finding customers, need extra capacity and need to pay more for crew among other things. The newer, slower speed is just a compromise between all those factors. 3 weeks is likely too much of a slowdown

I'm curious if solar powered ships are viable. Wind is a proven technology for ocean travel, but it has some notable downsides. Solar-electric vehicles would have more flexibility, since the sun is more predictable than wind, and the direction of travel is less relevant. However a solar ship above all else needs a very large surface area in relation to the amount of power required to move the ship. (thus encouraging the lightest possible ship with the largest possible deck surface area) I suppose this is unlikely to work well for freight transportation. And given the design constraints it would seem the most obvious candidate for testing this would be catamarans...

3:33 "positive impact" on marine mammals... well : saying a "less worse impact" would be more correct. :/

Little Joe is seen hitting his hand with a hammer. Every time he hits his finger, he shouts out with pain. Guy asks him: "doesn't it hurt"? Joe says "Sure as hell it hurts, this is a hammer I hit my fingers with you moron" Guy asks: "then why the hell are you hitting your hown hand with a hammer?" Joe says "sometime I miss it and man, that feels fantastic". So much about positive impact...

Would it be possible to have an adaptive bulbous bow? One that changes it's length/height in front of the ship to adapt to the speed of the ship therefore making it more efficient at multiple speeds, and more efficient overall.

Unfortunately not as the cost of implementing something like this would far exceed the vessel's budget, and any frontal collisions could lead to expensive repairs. I doubt there would be any real tangible savings from this in the long run anyway. Owners would rather wait for the rolling out of green engine technology which hopefully we'll see progress on later this decade.

"Is it all about profit, though?" Basically yes, until governments _make_ companies care about the environment, especially companies like shipping companies that don't really have direct interaction with consumers. Because it's almost always cheaper (and therefore more competitive) in the short term to not care about the environment. Long term, though, definitely better to not ruin the place we live.

2:33 Alright - what I am about to say is meant to be kept a secret. Just between you and me here in the comments. I have a foolproof method to make tons of cash. Drive your ship in reverse, so it will go -10knots/h for example. By driving with negative speed, you will actually gain fuel, that you can sell once you have arrived at your destination.

I have spotted a flaw in your plan. If you're steaming with negative speed, wouldn't that mean you will arrive at your destination before you've set off from your origin? Too much of that sort of thing going on and we'll break physics matey. 🤔

Speed is more or less determined by the state of the shipping market. Prior to early 2021 when the market was depressed, ships were put on Eco Speed (slow steamed) in order to lengthen the voyage and laden days (days in which cargo was aboard) and to give the company more time to fix good business for her. A depressed market does have its pros and cons. Cons being shipowners struggle and must find ways to slash operating costs and cut the fat of their business. The pros being low freight costs for charterers and helps the industry get rid of old vessels as it's more profitable to sell such old decrepit ships to shipbreakers than to put them into business and compete with newer ships. However 2021 saw shipping rates (especially in the drybulk sector) skyrocket to pre-GFC levels. Suddenly, all ships went to full speed as owners wanted to finish the current crappy charters and fix in at the new rates. And all those old ships are now being put back to business because their owners want to capitalize on the market before the ships completely fall apart!

Also I should mention if they were ever going to be serious about the environment. Electric driven motors are by far more efficient in powering a ship. In fact it would be much more efficient to run your ship using diesel generators on your ship to produce the electricity to run the more efficient electric powered motor. So you'd use less diesel and have a more powerful motor propelling your ship. Its a practice that's used by many fishermen in South East Asia. Where the costs are as tight as can be so they can profit from their efforts.
