Abstract
The subsea pipelines play a significant role in secure transportation of oil, gas and other energetic resources from the seabed to the shore and bases. The research of the hydrodynamic forces in the subsea pipelines and risers is a key factor from the point of view of regularity and efficiency of technological processes. The paper studies the impact of hydrodynamic forces affecting the subsea pipelines in the Caspian Sea. For diameter and thickness of pipe wall selected according to the ASME B36.10 standard, the forces of wind, wave and current, as well as the combination of forces affecting it were studied. The research was carried out in SACS computer software for three cases; as a result, the simulation and a table of force combinations for the optimum and unwanted occurrences appearing due to the impact of hydrodynamic forces and load combination were developed.
