下面这句话如何翻译。
The dock is to be capable, when floating in fresh water of lifting and carrying a vessel displacing 25000 tons, when the freeboard at the midline of the pontoon is 9 inches.
A ship has different displacemnt corresponding to her different draft.
The capacity of a floating dock is the biggest light ship weight(light ship displacement) of a vessel the floating dock is capable to lift and and carry. So, usually we don't use ship's displacement to indicate the capacity of a floating dock.
yes,i know the capacity of a floating dock is the biggest light ship weight. but this dock give us the lifting capacity is 25000 tons on general aggangement and the dimension smaller than our floating dock which lifting capacity is 16000 tons. so i feeling at sea.
Thanks for your response.
I would suggest you to check following if you need to get clear picture on this matter:
1. the dimensions of these two floating docks;
2. the pontoon sizes of these two floating docks;
3. the material (concrete or steel ?)and weight of these two floating docks;
4. the maximum water weight of these two floating docks discharged for lifting ship;
and
5. the distance from upper suface of the block of these two floating docks to their waterlines corresponding to ther maximum submerged conditions.
Thanks for your attention frist.
As your suggest i had checked the two dock except the materials. Because this is a new project and there have not any structure drawings. Now in your help i may be know why overseas dock is lighter than us. Our usually not use high strength steel except top deck.
Thanks you again my friend!
