FIELD: water-development works; berthing facilities and guards erected at points located far away from building bases. SUBSTANCE: three- dimensional framework of water-development module is made in the form of hermetic hollow beam whose height corresponds to height of hull of module. Transverse stiffness of framework are made in the form of watertight transverse bulkheads fitted inside beam. Hull of module is made in the form of closed reservoir embracing the hollow beam; bottom and deck of module are rigidly connected with it. Volume of hollow beam is no less than reserve of buoyancy of module hull. Upper part of each closed chamber of module hull and hollow beams are provided with hatches. EFFECT: availability of natural buoyancy of module and possibility of self-trimming when it is placed on bottom. 4 cl, 3 dwg
