DESCRIPTION:Three-dimensional linearized problem of hydro-elastic wave int
 eraction with a vertical cylinder of non-circular cross section in an ice 
 cover of infinite extent is studied using an asymptotic method combined wi
 th the vertical mode method. This cylinder can be considered as a leg of a
 n offshore platform which is used for exploration of oil and gas from unde
 r the seabed. Hydro-elastic waves propagate in the ice cover towards the c
 ylinders which are assumed to be frozen to the ice plate and fixed to the 
 sea bottom. The ice deflection is described by the equation of a thin elas
 tic plate of constant thickness. The flow under the ice is described by th
 e linear theory of potential flows. Strains along the contact line\, where
  the ice plate is clamped to the vertical cylinder are investigated for ne
 arly square and elliptic cross sections of the vertical cylinders. In addi
 tion to that\, the problem of ice loads acting on multiple vertical cylind
 ers of circular cross-sections frozen in an ice cover of infinite extent i
 s studied by an iterative method. Wave forces acting on a configuration of
  four identical circular cylinders are investigated for different ice thic
 knesses.\nThis research was funded by joint project TUBITAK (Scientific an
 d Technological Research Council of Turkey)-RFBR (Russian Foundation for B
 asic Research) &ldquo\;Loads on engineering structures in sea ice&rdquo\; 
 with project no: 119N361 (TUBITAK)\, 20-58-46009 (RFBR).\n&nbsp\;\nDisibuy
