Harsh environmental condition – increased fatigue loading…

7. Moscow, Russia | 15-19 June, 2014
•Installations across three seasons
•Limit installation weight to 250 t to
maintain 400 t crane vessel segment
•Critical operations - pull-in of steel
catenary risers after spar installation
•And diligent planning…
…and reduced operability
