    Hello all,

    One of our tugs are about to have a bollard pull test and the we don't have a the minimum required water depth to do it. I heard DNV and LR has certain correction factor for water depth in order to compensate the lower than expected bollard pull value from the BP test in a shallow water depth. Can someone post more information or at least the rule quote here, so that it will be helpful. Thank you.
