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.
Reg.
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.
interesting web page. www.wikipedia.org/wiki/container_ship
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.
Tonnage: 275,276 GT
555,000 DWT
225,473 NT
Length: LOA: 414.22 metres (1,359.0 ft)

Draught: 28.5 metres (94 ft)

Installed power: 64,800bhp (48,321.5kW)
Propulsion: 4 ? Stal Laval steam turbine engines
2 ? propellers
Speed: 16 knots (30 km/h; 18 mph)
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.
Er, Pablo, Iknow Cap'n Kong personally and he is'nt really obese.........but his ships were somewhat bigger than usual,like the man himself!

Ha, you said that Brian, I shall be blamed for nowt.Quote:

Then you get a F.O.C ship coming down the channel the wrong way with no communications and apparently no one on watck, yes it can be a sweaty situation and you find yourself with two ciggies in each hand. Then the Cross Channel Ferries flying past at close quarters.
Stood on the bridge looking ahead the nearest clear water you can see is half a mile away over the bow. If any snall vessel is less than the half a mile you cannot see it, even on Radar the sea clutter can wipe out an image at that close distance.The English Channel is one of the busiest waterways in the wordl. there can be as many as 2000 ship movements through there.
I enjoyed doing it until we took all the big tankers to Taiwan for scrap even tho` they were only 10 to 12 years old. we then went on the North Sea run on 125,000 ton tankers like the Esso Aberdeen to the Brent Spar at the top end.
Ha,Ha, Two ciggies,good stuff! But,why were the tankers scrapped? I thought bigger,was better,re' oil,etc!
They became Dynosaurs, they were designed that big because of the Suez Crisis in the 60s and 70s. sailing around the Cape instead of thru` Suez. then North Sea Oil came on stream so there was no need to go to the Gulf as often. and also they didnt need as many tankers for the trade as they were shorter voyages.
Seems obvious,now you've explained it,but I wonder if they'll come back?Quote:

The biggest ship sailing is a Post-Suez container ship. It may visit Liverpool when the new terminal is opened. But they have to start that first.
I always wondered why they never converted the tankers to container ships.
The British and French governments should have total control of the Channel, especially the Straights. Kong is right, ships ignore the lanes which are to keep ships apart and make the Straights into a motorway. In International waters they do what they like and can ignore any direction from France or the UK.
If ships do not take any notice of the controllers they should be buzzed by choppers and if no response boarded. The collision rate is far too high in the Channel.
I though modern day ships have cameras on the bows, etc, so the bridge know what is all around and make it easy using bow thrusters,.
Isn't Istanbul the busiest shipping lane in the world?
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. :)
Did you board her?Quote:

Just a reminder of some details about Emma Maersk,with a typical future forthcoming voyage with dates and turnround times-not that there's much time for going ashore if you're on duty!
Name: Emma Maersk Owner: A.P.Moller-Maersk Group. Builder: Odense Steel ShipyardLtd;Denmark.Homeport:Taarbaek;Denmark. Identification: Callsign: OYGR2 .General characteristics :Type: Container Ship. Tonnage: 170,974 GT
55,396 NT: Length: 397 metres (1,300 ft) LOA : Beam: 56 metres (180 ft) Draft: 15.5 metres (51 ft) Depth: 30 metres (98 ft) (deck edge to keel): Propulsion: 80 MW (109,000 hp) Wartsila 14RT-Flex96c plus 30 MW (40,000 hp) from fiveCaterpillar 8M32 .Speed: over 25.5 knots (47.2 km/h; 29.3 mph) Capacity: 156,907 metric tons (DWT)
11,000+ TEU
1000 TEU (Reefers) Crew: 13, with room for 30.
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.

Wow,your fast WW:PDT11
Good pic's WW!
Great stuff.
