THE CONSTRUCTION AND SERVICE RECORD OF A 306 FT. ALUMINUM TRAILERSHIP
Construction contracts for a 226-ft aluminum trailership were signed in 1965. After two years of service, it was lengthened by 80 ft and returned to the Florida and Puerto Rico trade. Several months after jumboizing, some problems were encountered. The majority could be described as nuisance cracks; however, several areas deserved analysis in order not to compromise the integrity of the hull. The ship was thoroughly inspected. Hard spots, inadequate bracketing, and fabrication details which prevented sound joints were judged to be responsible. This condition was thought to be aggravated by the lengthening and heavy slamming due to the shape of the forebody. Model tests disproved the slamming theory. It was decided, therefore, not to alter the lines of the ship. A modification plan was adopted to correct internal structural inadequacies. The ship's construction and lengthening are described. The results of numerous inspections and the methods used in effecting the structural changes are reviewed.
