Traditionally

Ballasting operations are performed using a prepared ballast procedure, information from the loading computer and an on-shore measuring system. While operations get more extensive and complex, data-gathering, visualization and logging of the load transfer, stability and longitudinal bending are rarely done.

How we do it.

We start stability software twice and have both entries communicating with each other. The first entry reads the tank sounding and calculates the drafts. The second entry compares the calculated draft with the measured draft and calculates the load delta with its cog. This delta is the load already skidded on board or in the hook.

How does this help you?

The program calculates, logs and reports in real-time the external loads, stability, heel, trim and draft for any floating structure. The vertical alignment of the barge or vessel relative to the quay is calculated and presented.

For float-over operations, the LMU loads are calculated.
For salvage operations, the grounding force is calculated, and the variations in grounding force are due to tide, ballasting or pulling. With this information, the required parbuckling force can be calculated at any time.

All information is shown on a windows computer screen. The essential information is provided in large font size on a separate personalized window.

At regular time steps, the data is logged to an excel file to allow for evaluation after the operation’s completion.
