TORSIONAL TESTING OF OPEN BULK CARRIER FRIEND SHIP

The cargo ship Friend Ship has extremely large hatch openings compared with more conventional types of cargo vessel in order to improve the loading and unloading efficiency of containers or long cargoes. The design meant that problems of upper-deck stress and distortion of hatch openings accompanied by twisting distortion of the hull had to be investigated. Stress and distortion measurements were carried out on completion to check torsional strength and accuracy of the calculations made, which were based on finite-element analysis. It was found that the hatch-corner stresses were very high, so that these areas require particular care in design and construction. Order from BSRA as No. 52,273.
