damage occurs to the pipeline, as is the desirable intent, then the equipment will never be
used. Also, based on the results of a risk assessment/occurrence probability analysis, the total
investment cost for a repair using a diverless repair system could be compared with the cost of
a repair performed by relaying a section of pipeline and performing the necessary tie-ins in a
water depth reachable by divers. For these and other reasons it is absolutely essential to
choose a repair strategy that can solve all the envisaged repair tasks in a reliable and efficient
manner and at the lowest possible cost.
