Gangway Selection Guide
The main data we should consider is jetty tonnage level, tidal change, jetty plane status, price-performance ratio and other conditions. Users have to fill in the following parameter tables So we determine the scope of the gangway, basic dimensions and load data.
Jetty. Data
No. | description | data |
1 | center distance of gangway to edge of dock | m |
2 | dock level | m |
3 | design the highest water level | m |
4 | design the lowest water level | m |
5 | thickness of fender relaxed | m |
thickness of fender compressed | m | |
6 | voltage of power supply | V |
7 | frequency of power supply | HZ |
Vessel data ( million tons~ million tons)
No. | description of data | data |
1 | minimum distance of vessel flange axis to deck | m |
2 | maximum distance of vessel flange axis to deck | m |
3 | the thickness of protecting shipboard | m |
4 | transverse drift(perpendicular to deck) | m |
5 | total fore and aft drift(parrel to the deck) | m |
6 | sinkage value of vessel | m |
Environment data
Description of data | item | data |
maximum design wind velocity(10 meter upon the lowest water level, 3 seconds gust) | reset state | m/s |
movement/connect state | m/s | |
restoration state movement,connection state earthquake factor in restoration state | probability coefficient of earthquake Z | G |
acceleration of earthquake force | degree | |
environment temperature | highest | ℃ |
lowest | ℃ |
