Subsea Top Tensioned Riser Online Course
TTRs are long circular cylinders used to link the seabed to a floating platform. These risers are subject to steady currents with varying intensities and oscillatory wave flows. The risers are provided with tensioners at the top to maintain the angles at the top and bottom under the environmental loading. The tension requirements for production risers are generally lower than those for drilling risers. The risers often appear in a group arranged in a rectangular or circular array.
TTRs rely on a top tensioner in excess of their apparent weight for stability. TTRs are commonly used on a tension leg platform or spar dry tree production platform (spar). At the surface, the riser is supported from the platform by hydropneumatic tensioners, which allow the riser to move axially or stroke, relative to the platform. TTRs were designed for shallow-water use, but as the water depths grew, so did the need for new designs.
In shallow water it has been practice using top tensioned risers, but as design for larger water depth is accounted the need for new design practice has increased. The ordinary Top Tensioned riser is very sensitive to the heave movements due to wave and current loads because the rotation at the top and bottom connections is limited. The heave movement also requires top tension equipment to compensate for the lack of tension. If the top tension is reduced it will cause larger bending moment along the riser especially if the riser is located an environment with strong current. If the effective tension becomes negative (i.e. compression) then Euler buckling will occur.
