ACCOUNTING FOR THE VISCOPLASTIC PROPERTIES OF ICE TO OPTIMIZE DESIGN SOLUTIONS FOR OFFSHORE OIL-AND-GAS FIELD STRUCTURES IN SHARAPOV SHAR BAY

摘要

An individual approach to the determination of the ice loads on offshore oil-and-gas field structures in Sharapov Shar Bay, the Kara Sea, is presented. Sharapov Shar Bay is a rare example of fast ice that forms and remains stable over the entire period of maximum ice loads, offering an opportunity to optimize design solutions by accounting for the viscoplastic properties of ice. The results of field ice surveys in Sharapov Shar Bay are described, and an example of using them in ice load calculations is given.
