FIELD: transport.
SUBSTANCE: invention refers to shipbuilding, namely to pontoon ships intended for transportation on open deck the floating drilling rigs (FDR) and other floating and heavy entities. Floating vessel consists of pontoon with high forecastle (aftercastle) and free cargo deck. Bouyancy of aft (fore) end and longitudinal metacentric stability of vessel during bringing under (from under) FDR is provided by inflatable buoyancies attached to an end by means of flexible links of certain length determined by submerging depth of floating vessel required to bring in (out) the FDR. Echeloned (sequential) in direction of vessel bringing under (from under) layout of inflatable buoyancies creates virtually invariable depth of floating vessel submerging during vessel aft (fore) end passing under FDR's braces. Inflatable buoyancies are located below base surfaces for large-dimensioned cargoes.
EFFECT: enhancement of floating vessel operational functionality due to possibility to bring a floating vessel under transported floating entity both from boards and from aft end, also transportation of unlimited in width heavy cargoes is provided.
