EN3501 Dynamics Coursework Semester 2 2021/22
Coursework brief
The aim of this coursework is to model the following structure as a lumped mass model with appropriate degrees of freedom.
A conductor supported platform uses the structural strength of the well conductors to support the platform topsides and process equipment. In this case, 4 conductors are used to support a 15,000kg topsides and process equipment as shown in figure 1 and 2 simplified layouts of the design below.
Each conductor also contains steel casing. Each set of the concentric tubes are cemented at various depths below the seabed. All dimensions, weights and material specifications for the wells are shown in Figure 1 and 2.
Since risers are exposed to environmental loads (waves, wind and currents) in the offshore locations, they will vibrate axially, transversely and torsionally at low frequency. To design a safe structure, it is important to know its natural frequency.
