Stability calculation and problem solving is a particular expertise of MDI with detailed analyses carried out on fishing vessels, offshore supply vessels, lifting barges, passenger vessels and workboats.

We will maximise your vessels capacity whilst remaining safe and within regulatory criteria. If required we can investigate how her characteristics can be improved to either increase capacity or improve her motion.

For marine contractors we offer a rolling consultancy service. Once we have your vessel details the effects of particular loads, machinery or lifting operations can be checked immediately to allow you to make decisions on the correct  vessel for the job and quickly sign off an operation as safe to perform.

There are multiple criteria for vessel use or flag state regulations and we are able to advise you on requirements  for your area and type of operation.
