MANAGING REWORKS IN A SHIPYARD INVOLVING HULL REPAIRS OF COMMERCIAL VESSEL

Abstract

Availability of many commercial vessels nowadays is prompting local shipyards to increase their revenue by offering best maintenance services in ship repair industry. Reworks, occasionally, may cause negative impact on project performance involving hull repairs that adversely affect the whole shipyard operation through unnecessary additional cost of repairs. Hence, it is vital for a shipyard to plan any repair work properly to avoid issues of project delays due to reworks caused by non-conformity on quality issues. The researcher had distributed total of 30 sets of questionnaires to employees in a shipyard located in Lumut. The questionnaire covered three (3) sections, namely section A (the demographic data of respondents), section B (scope and guideline content) and section C (suggestion and opinion). The research findings revealed that most of the respondents had indicated the main root cause contributing to reworks for commercial vessel hull repairs is due to defects found on the welding beads. The weld failures caused by hydrogen cracking is the main contributing factor causing reworks for hull repairs that result in production delays and overruns in a ship repair project and finally affecting the total profitability of the shipyard.
