Use of Hydroelastic Analysis for Verification of Towed Equipment for Acquisition of Seismic Data

Abstract

This paper presents how analysis can be used in the design and the design verification process for towed equipment. Analysis of a seismic gun array has been carried out and points out the challenges that need to be addressed in order to obtain an assessment of the system. It is shown how analysis should be carried out to obtain proper design verification. Applicable rules and design criteria are presented and discussed. The work shows the importance of carrying out a coupled hydroelastic analysis of towed equipment. The strong effect of waves and currents to positioning of equipment is shown.
