 :o....the more I  look at this image, I find it difficult to understand just what [despite 3 x thrusters & twin Korts nozzle population] and  how this vessel got to this position?.....and what was it doing?................... so now is it a light movement astern together with a gentle thrust to STDB?

Maybe the original post and picture should have gone in the Random Caption Competition thread  ;)
It certainly has lots of potential  :-)

Makes a change from my threads being deleted %)

The ship master was indeed turning the ship - to re berth in the same place but facing the opposite direction :o :} I can't remember exact dimensions but the ship is I think 92metres, the river is 115 metres, but as you can see there is also a moored craft just behind the bow. But kudos to the skipper for believing in his abilities to turn it there.

When surveying in the Forth, we used to
Berth each night in Methil.
Where we berthed the channel to the main
Basin was 120 feet wide.
We were 107ft load and the skipper, used
to turn us ready for the next morning without
Touching the sides using only twin rudders
And controllable pitch props.
No bow thrusters back then on RN survey vessels.

Probably a teenager or someone's wife... they know 'jolly well' everything!   O0

.... no can't be a woman, steering was involved.

Vessels with her propulsion system can turn on a six pence, used to turn the Sal class boats in similar circumstances. The large ferries in Portsmouth often turn off Fountain Lake jetty in similar circumstances.

Newhaven - Dieppe ferries do(or did) similar at Newhaven. When I tied up on the outer pontoons of the Marina opposite the ferry terminal, it got VERY scary when that huge bow loomed no more than 20 feet from my 27 footer! Cold sweats I remember, but great ship-handling.

So does the photo give a misleading view and he did actually turn it? Or has he just hit the green job?

They still do at times, though the current 'twins' are quite capable of leaving stern-first in all but the worst of conditions. They're 'Newhaven-Max', built to just fit in, and there's probably even less than the 20 feet clearance these days.


If I could turn 'Meeching' on the spot with simple twin screws and twin rudders, then a vessel equipped with korts and/or AZDs, plus bow thrusters should be able to do anything! It's a careful manouevre we're looking at, but certainly not a brown trouser moment (unless you aren't careful enough!).

Hi,


On a restored historic trawler we often have to reverse out of a very crowded harbour.


But the trawler only has a single prop.


Using the 'walk' of the prop and rudder with a little ahead and astern on the motor it does not take very long to depart.

Thats the Kings Cross PD365 ( brand new in December ) and she's the biggest boat that can get in and out of that basin at Fraserburgh , she's 84m x 16m x 7m ( deep load with 1500t of fish aboard ) , the skippers of these boats make handling them look easy which it sure as heck isn't !!

Well Davie ...

That video is I assume on a very, very early morning without wind or even a hint of breeze %)......and to compound the boats departure from the basin, is that she [PD365] must be absolutely light ship [and greater exposure to any breeze]

On her return [with 1500t of fish aboard ] I am guessing she would be still easier to handle and more stable entering port

when these boats are full they are a lot easier to handle in any wind , but , still need to be taken slowly into harbour

The bow and stern thrusters on these boats are 900kw/1208hp each , got her length wrong she's 78m overall there is a new 84m boat ( 2 very close in size ) coming this year so that will be even more of a tight squeeze

Main engine in her is 5220kw/7006hp but she has a shaft generator that can be powered off the other onboard generators to give her another 2500kw/3356hp for a total of 10,362hp for short periods ( usually towing for Mackerel which are a fast swimming fish ) so she has plenty of power to manoeuvre in harbour , max free running speed 16knots in ballast

Compared to the boats we thought huge 30 years ago she is effectively 4 times the size ( 30 years ago 50m pelagic boats were big boats and they had 10-11m beam and 5m draft with 3000hp )

http://fishingnews.co.uk/news/fraserburgh-partnership-orders-86-8m-pelagic-vessel/

86.8m x 17.6m x 7.5m(approx draft for Fraserbugh)

Replacing 2 60m sisterships but she will be the absolute maximum size for here and it will be an interesting first time in the harbour for them

One of the main reasons these vessels can carry out these tight manoeuvres is the use of computers with GPS stabilising data controlling the engines, some places they use other digital data, that is why they can stay on station within a few metres of a rig in severe weather, I forget the technical term for it but masters and mates qualified in using this gear not only are their certificates annotated with it but they are paid more for the skill.

The oil rig supply and standby boats all have dynamic positioning systems fitted but the large fishing boats don't , they rely on the skipper using the thrusters and engine

So now a computer does the job and they can relax with a coffee instead of wrestling with the controls for hours ... they get paid more!
That seems illogical somehow.  :o

The training is still the same basics though.


My mate's daughter has just come home from her first voyage to Japan, as a cadet deck officer, and it's still chipping and painting, mooring up, [ she was apparently on mooring and warping duties on the bow of her ship being shown the ropes by two experiences Ab's for an 11 hour stretch whilst going through the Panama Canal] anchoring and windlass  control, chart work, bridge watch keeping and getting her manual steering hours in over the 7 week voyage to gain her deep water steering certificate, steering under Japanese pilot control to name but a few of her duties. And she is loving every minute of her new life in the Merchant Navy.


So maybe all these new fangled aids do help in later life at sea,but the cadets are still taught the basics to a competent and confidant level, or they don't get signed off in their personal  MAIB training manuals until they do reach the level that the master seem confident with.
