Transportation Inertia Loads
Roll: amplitude period 10 sec
Pitch: amplitude period 10 sec
Heave:
X-axis : Surge and Roll axis
Y-axis : Sway and Pitch axis
Z-axis : Yaw and heave axis
The orientation of the deck on the barge that was assumed for the preliminary analysis is shown in the figure on the next page.
This orientation has been chosen to maximise the inertia loads on the structure and is not the finalised orientation.
The transportation model is adopted from the in-place model. The elevations in the in-place model has been retained in the transportation model.
This has been accounted for in the calculation of the coordinates of the centre of motion which is assumed to be at the waterline.
The transportation elevation of the bottom of the deck columns is assumed to be 8.00 m above waterline.
This elevation in the model is EL(+)12.000 m. Hence the centre of motion elevation is 4.000 m.
