The client intended to transport 8 barges from India to Indonesia, on a loaded submersible vessel with breadth about 42m. The cargo barges each have length about 70m and transportation of barges needed to occur in a manner which ensures safe and efficient transportation. GB Marine was approached to determine the optimum barge layout arrangement on deck and to carry out the subsequent transportation analysis. The purpose of the analysis was to determine whether the vessel and the barges were strong and stable enough to complete the journey.
