Abstract
In the study the probabilistic modeling of local ice loads and pressures on wide structure has been carried out. Probabilistic analysis has traditionally been focused on distribution of their maximum values. The “Molikpaq” (PA-A) ice-class platform for “Sakhalin-II” project is considered as an example. The input parameters were modelled by Monte-Carlo method taking into account of full-scale data in the Piltun-Astokhskoe field during 1989÷2002 ice seasons. A comparative analysis of local ice loads and pressures on wide structure has been made on the basis of the Russian and international design codes, standards and recommendations. The obtained local pressure values were compared with public available data collected on the “Molikpaq” (PA-A) platform. Some preliminary results and discussions are presented. Recommendations on the local ice loads and pressures for engineering design of structures on the Sakhalin offshore have been done.
