1235899 2011-10-07 23:32:00 Trev ... can you explain to us less knowledgeable folk ... how the hell you're going to get a ship or barge with a crane attached, together with another ship or barge for offloading the containers onto, close enough to the stranded ship without getting into a situation where they themselves risk running aground. It's not as though they can just pull up beside the stranded ship and crane then over the side.

Heavy lift helicpoters, Lama's or Mils would be the easiest & safest way to do it, but again, it's expertise in knowing the weights of containers and which ones to take off first to avoid the ship rolling and splitting up. Let's face it ... cost in this situation is secondary.

Assuming the ship is grounded mid-ships and it's 200+ meters long ... any crane would have to have a reach of no less than 100 meters, without taking into account any safe operating distances. I'm sure someone here will know the physics relating to lifting a full container on an arm 100 metres long, on an unstable platform, 50 meters from a reef.

1235900 2011-10-07 23:38:00 It is a fairly steep drop off from the reef so the crane can get pretty close. The cranes boom extends along way, so they don't have to get all that close.

Trev I think you are the one who is dreaming.

As SP8's says any barge may also get grounded and there is no crane in the world with a boom long erough that could carry a container.
Also where are these cranes of yours and how long would they take to get here.

At least the choppers would work, and if there were two or three of them, at least removing some of them may be enough.

There's $800,000 worth of wine on board so I am told!!

1235903 2011-10-08 01:17:00 Problem is Digby ... the weight per container and lifting several fully laden 40' containers in the wrong order may result in rolling the ship in the wrong direction. The stresses the ship is under must be enormous and I'm certainly praying that the weather stays calm so that it doesn't break up completely.

Payload is the maximum permitted mass (or weight) of payload, including the dunnage and cargo securement arrangements that are not associated with the container in its normal operating condition. Therefore, Payload = Rating - Tare Mass.

If the tare mass of a 20' dry cargo container is 2,400 kgs. and a 40' is 3,900 kgs., the payload of 20' is 21,600 kgs. (i.e., 24,000 kgs. minus 2,400 kgs.) and 40' is 26,580 kgs. (i.e., 30,480 kgs. minus 3,900 kgs.). However, the exporter may be prohibited to have that much payload in areas where there are legal limitations to the overall load of a vehicle.

In exporting, it is common to encounter a payload of 17,500 kgs. or less in the 20' container, and 24,000 kgs. or less in the 40' container.

1235904 2011-10-08 01:19:00 My pick is call in the experts (the Dutch), who are already involved. Then wait until the end of the month when the tides are are at the maximum. In the meantime prepare the ship to be floated off (repair holes, lighten and rearrange loads very carefully). Keep the the public away as the situation is dangerous. nerd89 (14761)
1235905 2011-10-08 01:21:00 I'm keen to know how those columns of crates are strung together. There must be something holding them down, otherwise the ones on the edge would have fallen off long ago.

So that then leads to the problem of how do you free up the top container for removal without destabilising the entire column of containers.

Fastest and cheapest way I can imagine of getting rid of the weight of the cargo is to extend a rope ladder down the sides and tell the public they can help themselves to the contents of any containers above deck (which naturally won't happen).

There's enough hungry locals with boats who'd consider raiding the vessel... or at least they would if the cargo was a bit more sexy than milk powder!

1235906 2011-10-08 01:38:00 Has anyone given any consideration to sending a container load of balloons to the Beehive ... every MP could blow up about 1000, attach said balloons to ship, and just let the whole bloody thing, ship and containers, float away .... :D

Alternately, Paul could stand astride the highest container with a couple of cans of Links, take his top off and spray away ... when all the blondes in the north island arrive, he could tell them the containers are full of anti-aging cream ... problem solved ... they'd just throw the containers overboard and paddle them to shore ... :D

Geeze ... I would have done well at Apple ... I can think outside the box !!!

Sure the cranes are not in NZ but they are available from oversea's. I have seen a few of them on documentrys on Sky TV.
