Disclosed is a modular offshore platform for use in water depths of 160 feet and less. The jacket assembly of the structure is composed of interchangeable stackable modular units. The horizontal cross section of the jacket assembly has a truncated triangular configuration. Some of the vertical members of modules of the jacket assembly are adapted to allow the passage of piles which function as conductors and some of the vertical members are adapted to allow the passage of piles only. The jacket assembly is designed to lie well beneath the water surface so that it is not subject to great wave forces and does not need to be battered.
