Sažetak
The increase of world demand for the energy resulted in a high energy price, which have reinforced the interest in the development of new oil and gas fields in deeper sea or in harsher environment area. Due to a significant reserve of petroleum and gas north of the Arctic Circle, further field development and increase of exploration in Arctic region are expected in the incoming decades. In Arctic region, the harsh environment leads to serious challenges in the design of off-shore units. Between different scenarios of unit hull and ice interactions, a possible collision with the icebergs requires particular attention. This scenario is discussed in the paper for the case of floating moored off shore unit. Depending on the iceberg properties and its size and mass relative to the offshore unit dimensions, the effects of collision on the unit are discussed and analyzed on two levels: global loads on the unit and local hull structure loading. The external collision mechanics is analyzed taking into account parameters of the collision, mass and drifting speed of iceberg. The energy absorption during internal mechanics of collision, due to iceberg crushing and unit structural deformation is calculated using non-linear FEM explicit procedure. The energy absorption curve during the collision is calculated and discussed.
