As a sonar technician, I can tell you that sounding equipment in commercial vessels is NEVER in the bulbous bow. Never. The transducer for any such device is installed in the best available spot under a vessel, where cavitation won't be a problem. This is often far forward on the hull, but never in the bulbous bow. Some vessels have the transducer mounted towards the aft end of the engine room, but again it depends on the ship hull design making that practical.

[@1972danhall]

The bulbous bow is usually part of a ballast tank(water for draft/trim/stresses). Some ships have it as a void space (air), but not many. The design and shape of the bulbous bow is designed for the optimal draft and speed.

[@weldmachine]

Great information. But, the question ?? What's Inside 👈 That was the part I was interested to know ???

[@villaverjaymar4024]

There is nothing inside in this type of vessel.

[@caioaugusto3138]

​@villaverjaymar4024 there is _something_ inside. Either air, water, concrete or a man-made vacuum.

[@subvertedworld]

The bulbous bow also requires the boat drafting a certain depth, and traveling a certain speed for optimal benefit. It actually doesn't help 100% of the time.

[@henryostman5740]

The speed of a ship is limited by its waterline length (measured at the waterline from bow to stern) in feet it works out to the square root of the WL times a factor, generally the factor is approximately 1.34, to go faster than this, the vessel must change from being a displacement type to being some kind of a planing hull like a speed boat, this means that the vessel is using the lift generated by its forward speed to lift the hull out of the water and fly over the surface, doing this requires a lot of power. Your comment that larger ships have bigger engines is largely true but generally increasing the power of a smaller vessel won't make it much faster. Using my formula, a 900' ship could go as much as 40 knots while a 400' ship could only do about 25. Most merchant vessel actually operate way below their potential top speed both due the desire to be more economical in fuel consumption, and that they lack enough power to actually achieve that speed. Vessels with fine lines will go fast than fat ones, thus the canoe is faster than the rowboat of the same length. A thousand foot cruise ship probably can do about 23 kts max while an ocean liner like the Queen Mary can do the mid thirties while the aircraft carrier gets into the forties. The cruise ship probably has propulsion motors (most are diesel electric) totaling about 50,000 hp, the Queen probably about twice that, while the carrier will admit to 250,000 hp (and probably makes a lot more), fuel burn for the cruiser would be about 100 tons/day, the Queen about 200, and the carrier would burn about 500 tons but it's atomic powered. Anyone want to pay for 30,000 gallons of diesel oil each day? That's about a hundred tons. Remember too that these ships use a lot of electricity and it probably takes about 25 tons of oil daily to keep the lights on. By the way, if these ships had steam engines like the old Queen Mary or the SS United States, they burn about twice the fuel tonnage daily.

[@Stu-SB]

Excellent write up, thanks for this 👍

[@bholdr----0]

Wow... That was more than I needed to know, but, heck, I'm glad I read yer post. It is very informative, and I appreciate the effort you put into it! Cheers!

[@germanshepherdlover2613]

SS United States was a streamlined rocket. My favourite old ship 😊

[@ronblack7870]

ships still use heavy oil at sea so almost like asphalt ., but that is changing due to maritime regulations . near ports they usually have to burn low sulfur diesel . ships are also putting in scrubbers which basically move the particulates into the water instead of the air. others are actually switching to propane.

[@The_pipeliner]

Well I know my cruiser weighs 16,000 kilograms.

[@TheCarterKent]

The ship fueling process is done over 90% of the time at the dock. Fuel barges, some powered, some driven by tugs, bring fuel to where the vessel is docked and pump it onboard. Doing it at sea may be practical for a relatively small number of vessels but it is very impractical for any vessel that can simply pay for fuel delivery at whichever dock they frequent. In the case of LNG (liquid natural gas) vessels this is particularly necessary.

[@jimlaxdal9023]

So whats stored in the bulbous nose of the ship ?????

[@rtqii]

Air. They are empty.

[@terrymoore1830]

[@johncharley9791]

The bulbous bow is hollow but strengthened, using girders, floors. In reality it is a very strong void space accessed via welded manholes or bolted manholes. It also reduces bow pressure and thus more fuel efficient.

[@davea4245]

Floors eh...someone has worked in a shipyard.

[@theshapeexists]

I would imagine it's also made into a watertight section in case its punctured.

Bulbous Bows actually started with WW2 Subs. The Bulbous was where the Submarines sonar was located. It was only by that Sonar feature that they found the bulbous was beneficial for vessel efficiency.

[@wavehaven1]

[@harrynikken]

In some merchant navy ships the bulbous bow contains the echosounder so the bridge knows how much water there still is under the bow. In many ships this instrument is located a bit more astern in the forepeaktank.

[@danaustria1056]

The purpose of bulbous bow is to reduce the drag and improve the ship's speed.

[@tsclly2377]

'Hump' speed increaser.. helps prevent bow rise and bottom plane angle that caused increased drag as the ship stars to get into a configuration of rising to plane, thus a climb angle as water is relatively incomprehensible... also due to the propeller(s) in the back (stern) are increasing the velocity of the water they go through, they also suck the rear down to a degree.

[@jshumphress13]

That’s nice that there’s an international “agency” to deal with trash from ships… but who is going to enforce it? If a cruise ship or cargo ship dumps all their waste in the middle of the ocean, who is going to know? It’s a good idea in theory but doesn’t work in practice I fear.

[@JesseJ588]

I'm sure the ships have to produce receipts to the IMO proving they recycled or properly disposed of a certain amount of waste. Dropping of scrap metal and aluminum and plastic probably actually will pay the ship, which will also need to be filed for tax purposes. But if the IMO designates that they need to do this I'm sure the ship has to prove they did it. Not to mention if the company could lose their license to operate if they don't it's not likely an entire crew will just disregard it. Someone is going to report something. I would.

[@vamoscruceros]

​@@JesseJ588Princess Cruises was busted when a crew member quit and reported them to authorities. I think these days, though, operators see trash and/or food waste, as potential sources of energy. Carnival Corporation is using digesters filled with bacteria to reduce food waste to liquid waste that can be treated alongside wastewater. Royal Caribbean is implementing a new system that uses microwave-assisted pyrolysis that converts waste to gas that can be used to power the engines.

[@dieselyeti]

Heavy fuel oil (bunker oil) is now regulated by the IMO to allow low-sulphur fuel only. If a high-sulphur fuel is used the ship need exhaust scrubbers to remove the soot from the exhaust plume.

[@NigelTolley]

It might turn out that was a mistake. All that sulphur was feeding the plankton and blocking the global warming a bit. Not now.

Speed of a ship has nothing to do with how long the ship is. It has to do with power to drag racio. The longer the ship the more the drag. A smaller boat with more power to drag can easily move faster.

You might want to read about hump speed and hull speed. Given the same horsepower longer hulls are faster than shorter ones.

@@RustyorBroken To an extent i do accept the physics involved. However, a 100hp engine is not going to drive a 100' ship as fast as it would a 10' A battleship has a lot more power than a speed boat yet a speed boat is faster.

@@leostgeorge2080 your speed boat comparison is apples-oranges. Vessels like ships and sailboats move through the water. Speedboats, once at a critical speed, ride up on top of the water. That's called "on plane". The fact of the matter your initial statement "Speed of a vessel has nothing to do with how long it is." is incorrect. Yes, drag is a factor but hump speed and hull speed are greater factors. If what you say is true rowing sculls would be a lot shorter than they are.
