STATISTICAL PARAMETERS OF STEEL TUBULAR MEMBER DESIGN FOR OFFSHORE PLATFORMS IN MALAYSIA

The exploration and production of oil and gas in offshore industry of Malaysia is conducted by, mainly, means of jacket platforms. These are tridimensional frames formed by welding steel tubular members, which support the exploration and production facilities. The design of these structures follows...
