Greetings Banda,

Coke -no not the soda!!!!

Specific gravity 0.42

Weight: lbs. per cubic foot =26 pounds

Weight: lbs. per cubic yard=702 pounds

Weight: kgs. per cubic meter= 416.5 kilograms

Conveyor slope maximums:

Coke, Breeze= 20 degrees

Coke, Screened=18 degrees

Lesson number 1.

Any material, I repeat any material will create dust at transfer points as dust is created from the conveying and transfer to the recieving vessel whether it is a lorrie or a cargo ship.

1a.

The ideal is to have one point for loading and load directly into the carrier from the storage area with out transfer points.

1b.

That is never the case usually as their are fewer and fewer new ports for bulk loading and unloading of same.

1c. The actual act of transfering the coke will create dust anyway and the best way to deal with it is to have covered conveyors covered transfer points and a telecoping loading chute( donkey Dick) on the end of the loading boom to reduce dust to a minimum unless you want to bag it all in super sacks and reduce dust emmisions even further but the law of diminishing returns comes into play here unless you can back haul fertilizer in the bags or some other commodity that will not be affected by the metallurgical coke but do not reuse the bags for food stuffs!!!!!!!

A crane with a grab will generate a lot of dust

A vacuum system/pressure is possible with a closed hatch system using dust control of the exhaust.

Static electricity must be dealt with as the potential for dust explosions is exponential in relation to the material moved so adequate grounding at the hatch and transfer points is a must.

Last but not least is the desired laoding time for the Panamax vessel as time is money and penalties are paid for extended time in port.

Coke costing: Is the coke priced on an actual basis for resale and not discounted to capture market share?

Example-wyoming coal is heavily discounted for sale.

You may be money ahead selling it in your own area with out shipping it as the carrier will include a fuel surcharge per net ton to cover fuel costs. remember you are dealing with a very light material and it will effect ship ballasting and loading.

If you have a metallurgical grade coal it may be more valuable without coking as it has a high BTU value in itself.

Is a land route possible with the coke to your coke customer or a coal customer?

A capsule pipeline would be perfect for this. ■

Dear Banda,

We design and build shiploaders and can provide a no cost budget quote, with just a little more information. We''ve built 13 shiploaders with 7 of them for pet coke or calcined coke. Dust control was a concern for all of these. Please visit our website at:

www.agricosales.com

Or email me at:

brieck@agricosales.com

Or call me at:

Gentlemen,

Hoping not to hijack this thread, but thought it appropriate to place in this particular thread.

Am looking for the best options to moving metallurgical coal from a barge to ship.

We hoped some specialists could enlighten us on the latest industry options. All information/links appreciated.

Lionel ■

I think it will be worth your while considering ship mounted grab unloaders. You moore the barge to one side of the ship, the receiving ship to the other side and transfer between the two with a machine that can travel the trolley the whole way.

If you then wish to stockpile the material, you can temporarily load it into the transhipment ship.

Please feel free to email me for further information. ■

Posibilities:

1. A mid-stream transfer system:

a. as already described using clam shell unloaders to hoppers at the mid-stream barge. From there, a shiploader boom to the ship.

b. A catamaran type continuous barge unloader using a high tonnage bucket ladder to a ship loader.

2. Self-Unloading barges with discharge boom.

In any case DSI Snake Sandwich High Angle Conveyors can facilitate the high volume material transfer in limited space.

Thanks gentlemen. I'll be in touch directly.
