This study proposes a non-contact approach for tension evaluation of a large-scale cable-
stayed roof. Three-dimensional (3D) laser scanning data based on a terrestrial laser …

As water depths for oil and gas exploration and extraction increase, structures such as
flexible risers, mooring lines, and umbilical cables are increasingly being used for subsea …

A marine riser operated in deepwater could encounter harsh environmental conditions and
exhibit complex vibration phenomena which require thorough investigation, especially using …

This paper investigates the nonlinear free vibration of a marine riser with large
displacement. The nonlinear equation of motion is derived using a variational approach …

This paper investigates the force features of inclined pipes under the action of waves and
flows through both test and numerical simulation. Firstly, the wave and flow loads on inclined …

The main goal of this study is to investigate the free vibration analysis of a large sag
catenary with application to the jumper in hybrid riser system. The equation of motion is …

A marine riser operated in a deep-water field could be substantially affected by large
amounts of movement of the floating platform, which is more complicated and very …

This paper presents a variational model formulation for free vibration of a very-largesag
extensible catenary riser. In the static equilibrium state, the catenary riser has a large-sag …
