Largest Propeller

[bangorreg]

Hi."Acknowledgement to Arco Publishing Co . NY. For this "Photo".
The world's largest ship's propeller has been manufactured by Hyundai Heavy Industries for a 7,200 TEU container vessel owned by Hapag Lloyd. As tall as a three storey building, the 9.1 metre diameter, six bladed propeller weighs in at 101.5 tons.
The following photo is a 72 ton propeller fitted to the tanker Loannis coloctronis.

A real big one. The ship is not that large, only 7,200 containers, when many Panamax hold 14,000. Two props gives backup. May one is for cheapness of manufacture and/or cheap in running costs.

Amazing. There are still a couple of large props on the waste ground of the former SMM foundry by the tolls of the Wallasey Tunnel. They just seem to have been abandoned. I believe the Titanics prop was made there.

The 300,000 ton tankers I used to navigate had a 4 blade Propeller 9.7m in diameter. approx. 32 feet.

The biggest ship I ever went on was the Batillus, 555,000 DWT
she had two props and two rudders.
I landed on her fore deck by helicpter and went on the bridge, off Cape Town in August 1976 on her maiden voyage, she was bound for the Gulf. so I sailed around the Cape of Good Hope during a six hour helicopter operation to transferr stores.
She was BIG.

Nice one Captain. I believe they are a bugger to stop.

Hi Pablo,
they are quite easy if you know how.
If I had to do an emergency stop, tho` I shouldnt be in that situation in the first place, I can stop these giants in six tenths of a mile, with the engines still going Full Ahead.
eg.
Tanker 300,000 Deadweight tons.
Course is 180 degrees, engines full ahead, 16 knots.
Emergency stop.
Do not touch the engine controls, leave on full ahead.
Wheel Hard a starboard. alter 90 degrees.
The ships head will turn to starboard, bring her to 270 degrees.
The ship will carry on along the course line of 180 degrees beam on to the sea with the momentum, After six tenths of one mile the cushion effect of the under water draft of 65 feet and the length 1200 feet will bring the ship to a halt in the water.
She will be stopped with the ship`s head facing 270 degrees, before she starts to pick up speed just pull back the controls and stop engines.

If you went from full ahead to full astern to stop her you would rip out the engines.
as I said before you should not be in that situation in the first place.

When I alter course to a new course then I alter six tenths of one mile before the charted position, the ship will then slide to the charted position then carry on with the new course.
They are very easy to handle if you know the ships limitations

Reckon it's like that with everything Captain. If you know what you're doing. Did heavy storms give you much problems or wasn't you bothered cos of your size.

Very interesting

[Oudeis]

Just to let you all know, you may know already.
I was sent a picture of a cargo ship registered in Hong Kong. Called the

"TITAN URANUS".

Sound advice.

Docked, we were. With the Quay in the Lock.

Engine and Hull

The Emma M?rsk is powered by a Wartsila-Sulzer 14RTFlex96-C engine, currently the world's largest single diesel unit, weighing 2,300 tons and capable of 109,000 horsepower (82 MW)The ship has several features to protect the environment. This includes exhaust heat recovery and cogeneration.. The exhaust gases of the engine are passed through a steam generator which then powers electrical generators to generate electricity. This creates an electrical output equivalent to about 12% of the main engine power output. Some of this steam is also used directly as shipboard heat. Instead of biocides, used by much of the industry to keep barnacles off the hull, a special silicone-based paint is used.This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicone paint covering the part of the hull below the waterline is credited for lowering the water drag enough to save 1200 tons of fuel per year.
