Harsh environmental condition – increased fatigue loading…

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

Moscow, Russia | 15-19 June, 2014
