Abstract

Offshore structures such as boats, ships, oil rigs etc. are under continuous wave loading. These waves exert pressure on the structure which in turn produces stresses in them. These waves can strike structure from any direction and it is very difficult to calculate the pressure exerted by the waves analytically as the shape of the offshore structures is rather complex. The pressures and associated stresses and buckling caused by the striking waves are harmful to the structure, and may lead to their failure. Keeping in view the above scenarios, the column of an offshore oil platform was designed on the basis of hurricane’s history of Arabian Sea. The normal and worst sea environment conditions were kept in mind while designing the column and its subsequent analysis was made on the basis of stress and buckling in this study. After analyzing the structure, it is known that the offshore column design is safe for particular sea state. The factor of safety (fos) was 1.90 and 1.77 for the normal and worst conditions, respectively. The pressure was decreased with the increase in wave frequency, while increased with the increase in wave amplitude. Further, buckling modes of extraction were in the range of 1.23 to 1.59.
