Abstract
The paper describes technology applied in laying the subsea crude oil pipeline in the coastal area of the northern Adriatic, between the steep coasts of island Krk and mainland. Very detailed functional plan was produced in order to avoid possible critical and unexpected situations in the installation process. The most critical actions of the process were numerically modelled and analysed in realistic numerical simulation to verify the defined project functional plan. The numerical model has taken into consideration large displacement mechanic and contact problem of elastic body in collision with rigid sea bottom. On the basis of the proofed functional plan a precise organization of the process was defined with a focus on the synchronization of all depending actions.
Keywords
