Case Study – Sea Launch Ocean Transport Measurement
- Sea Launch is a multi‐national joint venture company that provides spacecraft launch service from a mobile sea launch platform.
- Rocket components are manufactured in Russia, Seattle, and the Ukraine, and assembled in Long Beach. Assembled rockets are then shipped to launch site.
- Critical to evaluate shipping conditions that components and assembled rockets must endure during shipment.
- Lansmont SAVER’s with DC accelerometer instrumentation were used to record dynamic conditions during Sea Launch test shipments.
- Predominant frequency range was 0.10 Hz ‐ 0.15 Hz (overall Grms of approximately 0.015).
- Cradle design was evaluated utilizing data collected during study. Rolling motion could be damaging to assembled rockets.
