A methodology for the design of Paralympics wheelchair wheels has been developed and provided a framework for comparison between design solutions. Finite element analysis was used as a tool to develop an understanding of wheel design, provide a basis for evaluation of design solutions, and as a mean of design optimisation. A finite element model of an existing wheel design was created and analysed...
This paper discusses the dynamics of a hybrid production riser designed for a water depth of 1500 m in the harsh environment west of Shetland where one of the main design drivers is offshore installation time. To minimise installation time, a free standing riser was developed comprising a carrier pipe, top and bottom taper sections and an integral subsurface buoy connected by flexibles to the moored...
