Marine Growth Data Form

The marine growth thickness on the structure is specified as a function of depth. By default a wave load is specified to have no marine growth.

Input the vertical elevation (measured from the datum) and marine growth thickness at each data point in descending vertical elevation order. If necessary, click the Order Rows button to reorder them in the correct manner. Note that the program will automatically reorder the data when you click the OK button to close the form.

The marine growth value used at a particular vertical elevation is linearly interpolated from the specified data. For a typical pipe member, two times the marine growth thickness is added to the diameter of the pipe when calculating the force exerted on the pipe by the wave.

Access the Marine Growth Data form as follows:

  1. Display the Define Load Patterns form using either of the following methods:

    • Click the Loads > Load Patterns command.

    • Display the Bridge Wizard; and then select the Load Cases item and click the Define/Show Load Patterns button.

  2. Specify a Wave Load Type and an Auto Lateral Load other than None and click the Add New Load Pattern button.

  3. Highlight the name of the newly define load and click the Modify Lateral Load Pattern button to display the Wave Load Pattern form.

  4. Click the Marine Growth Data Add button or select a previously defined growth definition from the drop-down list and click the Modify/Show button to display the Marine Growth Data form.
