Orca Offshore was hired by Ulstein Seas of Solutions to perform a pipelay workability analysis of the pipelay vessel SapuraKencana 3500.
The analysis has been performed using MOSES which combined the vessel motion analysis and the structural analysis of the stinger and the behaviour of the pipe in one model.
The allowable seastate has been derived for the following criteria:
- Stinger uplift risk
- Stinger slamming loads
- Stinger structural strength
- Stinger Hitch design loads
- Pipe load limitations.
