One of the basic analytical problems which often occurs in a performance analysis of tubular members in the sea relates to a correct understanding of the buoyancy phenomenon. A correct interpretation of physical laws relating to the so-called 'buoyant forces' is especially important when dealing with deep sea mining risers, deep water drilling risers, certain types of production risers, and when evaluating loads on marine pipelines during the towing and placement phases. This paper treats anaytical aspects of forces resultants on tubular members in the sea, as function of internal fluid density, external fluid density, internal and external pressure distributions, local angle of incliniation of tubular segments, local tension force in the tubular segment, and local body forces arising from the segment mass. This paper relates the local segment force systems to the overall force system through large deflection theory equations.
