As offshore activities move into deep water (depth of 3,000m and above), there is a growing interest to move from steel riser to composite riser due to the numerous potential benefits. One of the most significant advantages is that composite materials have higher strength to weight ratio compared to metallic materials and can be exploited advantageously to replace metallic risers at deep waters. Another potential advantage is that the bursting pressure of a composite pipe with adequate thickness exceeds that of a steel pipe. Comprehensive information on international standard properties of composite pipes has not been recorded till date and therefore there is a need to conduct theory calculation followed by verification through experimental results. Theory calculation will be performed using different international codes for steel and composite pipes and the experiments may be performed by a subsequent final year student as part of his/her final year project. Due to feasibility and cost limitation concerns, the experiments will be conducted using steel and composite pipe specimens instead of actual steel and composite pipes. To determine the pipe specimen bursting pressure, an internal pressure test rig is required to be designed. Functional analysis, morphological chart and concept evaluation learnt in Engineering Design (MP3011) through the Nanyang Technological University Bachelor of Engineering course will be used and applied in this design.
