abstract Since today's petrochemical industry is able to explore the seabed at the level of 3000 m, there is also a need to provide reliable, but cost effective enclosures for the respective technical equipment. This paper gives in-depth analysis of the design aspects for fiber reinforced pressure chambers, which are installed in the subsea environment. A chamber structure consisting of a metal liner and fiber reinforced composite is considered. Two theoretical models: for a generalized orthotropic material and for a laminated composite are recalled and used in the analytical study of the vessel. Finally, a structure optimization procedure is introduced and a verification example is provided.
