magnetic patches

[Keith Tindell]

Just been reading on the BBC news site that a cargo ship has been abandoned and towed into a bay down the west coast of Devon and sinking, all the crew are safe. The report says that divers will go down and attach a magnetic patch, something i had never heard of, is this fairly modern?. Mind you lots of things i never knew while at sea, it was only on here that i heard of concrete boxes and leaks inside the hull, i suppose you could say its the comfort of ignorance KT

Keith... Magnetic Patch, isnt that what arthur Itus sufferers use. Maybe ship suffers from same, all that cold water will not be doing it any good. Another well found ship (maybe) to join the annual toll of casualities. Cheers John S

She was bound from Liverpool to Shoreham i believe, in probably the most benign weather we have had for months, wonder how she would have coped with some of the storms we have had this winter?, or maybe she was out in that weather and that started the problem, KT

Every thing is possible these days Keith, there are ports now where mooring lines are not used because the quay is fitted with a magnetic mooring system, which is switched on when the vessel is alongside and Port Authorities will not allow use of mooring ropes. How this affects the magnetic compass no one has written about, well not in the periodicals that I receive. Cannot see the magnetic patch being watertight per se, but it will prevent an inrush of water much like the canvas and tarpaulins that we used in earlier times to slow down the inrush so that the pumps could manage to keep up or exceed the input of water. When I read my periodicals I am amazed at what progress has been made in numerous fields, although I am not in favour of all of them, but us oldies sometimes preferred to rely on our wits rather than computers. Then you have ports where they do not allow use of ship's generators in ports and vessels must 'cold iron' into compulsory shore supply for which they are charged extraordinary fees, all in the name of reducing pollution and complying with green requirements. I leave it to Rob to explain 'cold iron'

you are right there ivan a mate of mine bought what he thoughtwas a gold chain .....coming alongside the magnetswere put on the jetty and he dissapeared in a flash ....i say in a flash .....over the wall and was left hanging for 3 days

Cold iron, is a term used in the states, where the shore provides power for the ships whilst in port.
On arrival a port side power supply is plugged into the ships electrical system and the ships generators are witched off. The ship is then reliant on shore side generators.
The theory is that by using shore side generators you reduce pollution in the port.
I am not convinced, but it is another way o charging large fees to ship owners.

sounds like a dumping ground for devon.

[Captain Kong]

Holland America Lines Ships use shore power now in certain ports, The shore authorities do not like ships pumping sulphor laden fumes across their port.
I remember a few years ago the QE2 was heavily fined in Manhatten when she e mitted a load of black smoke.

I wonder, are these similar in design to the iron on patches for use on clothes?????

[Don Rafferty]

I used to have magnetic signs on my trucks which would mould themselves around any of the creases in the bodywork. If the marine equivalent is similar, I think they would work.
