DESCRIPTION:In this presentation\, it will be described which approach was
  taken to specify global and local ice loads for the structures in two dif
 ferent oil & gas projects in sub-Artic areas: the Sakhalin II project in t
 he Sea of Okhotsk and the Kashagan project in NE Caspian Sea. In both proj
 ects\, the approach was a combination of deterministic methods described i
 n the different design codes\, probabilistic methods and scale tests in an
  ice tank.&nbsp\; For the Sakhalin II project\, global ice loads were part
 icularly relevant for the design of the two multi-legged platforms (Piltun
 -B and Lunskoye-A). In contrast\, in the NE Caspian\, an accurate determin
 ation of the global ice loads was mainly relevant for design of the ice pr
 otection barriers rather than for design of the islands itself. Instead\, 
 much more attention was paid to specifying the risk of ice encroachment on
 to the islands. &nbsp\;In all cases\, it was found that the limited amount
  of ice data often resulted in a conservative design with still considerab
 le uncertainties in the design loads.
