Structural design, analysis and testing of GRP Streamer winch

Streamer winch for launching and retrieval of streamer cables on geotechnical vessels.

Client: Baro Mekaniske Verksted AS

  • Establish design criteria
  • Establish design loads, based on interaction between streamer cableand GRP structure – non linear load calculation
  • Design calculations and FE-analysis
  • GRP material evaluation and development of production method
  • Testing and verification of structure
  • Strain measurements on cable drum
  • Calculations and FE-analysis of test performance
  • Verification of design parameters and loads during test program, incl.strain gauge measurements
  • Analysis and evaluation of test results
