Abstract

See full text

A new jacket installation method utilizes inflatable buoyancy members for shallow water jacket installation. Two types of inflatable buoyancy members are introduced: 1) the first type is designed to produce a large water plane area in order to improve the jacket floating stability when it is afloat; 2) the second type is designed to produce net buoyancy when they are submerged under water, This new installation method is able to use a small size crane vessel, with lifting capacity less than the weight of the jacket to be installed, for a large and heavy shallow water jacket.
