ABSTRACT
Marine growth will potentially increase in structural weight, alteration of the natural period, increase in wave loading and increase in flow instability. Therefore, marine growth will effect on the jacket stresses and the value of dynamic effects of wave loads for jacket structures.The development of marine growth in the Vietnamese sea is different for each specific sea condition. Currently, jacket design standards of Vietnam have no specific regulations on thickness of marine growth for each sea area. So, analysis jacket structure, we have to use the thickness of the marine growth based on report of the specific environmental conditions of each field.This paper presents an analysis 03 wellhead platforms (WHP Thai Binh, WHP Thang Long, WHP Dai Hung) with 03 different sea conditions. From that, give some results and recommendations on the influence of marine growth to jacket structure in the specific conditions of Vietnam.
