Analysis and design of instrumented subsurface mooring

Abstract

The analysis and design of instrumented mooring is complex, since the environmental loading on the system may be static or dynamic and random. By using certain assumptions, an equivalent static loading system can be adopted and the problem can be simplified. The objective of the present study is to design and analyse single point subsurface instrumented mooring system under a three dimensional current profile. A software 'SUBAM' is developed in FORTRAN-77 and it is applied to analyse a shallow water current meter mooring. The results show that current force has more significant effect on the displacement compared to line tension. The point force due to waves or any other extraneous force has marked effect on the mooring line tension.
