Abstract: Offshore platforms are divided into many types which are mainly categorized according to water depth in the installation location. However, the design differs for each type to accomplish the target of the operation. In the early days, they were mainly made of wood and targeted locations in shallow water region. By the time needs of fossil fuel became larger, and the installation locations became far from the shorelines, so bigger and more advanced platforms were used. The modern types of platforms are generally made of steel, built onshore, and then transported to the installation locations. But for some case of sea water depths and an aggressive environment such as the North Sea, steel ones are not suitable, so the heaviest type called gravity platform having enormous mass is used. This type of platform has its special requirements and procedures for construction and needs special types of construction materials in order to resist the climate factors applied due to the aggressive environment. In this paper, the operating procedures, types and specifications of materials used, special ways of construction, transportation, and installation procedures for gravity platforms are presented.
