(57) Abstract:Usage: shipbuilding, in particular lifting facilities. The inventive pontoon has a tapered removable fairing 1, consisting of hinged petals 4 and mounted on the end of the pontoon belt, made in the form of a tape 6 having the element for changing the length of the tape, and the latch 7 of its length in a predetermined position. 2 Il. The invention relates to shipbuilding, in particular, to the design salvaging pontoons.Known for salvaging the pontoon, comprising a housing with a system for creating lift and towing eyebolts are installed.Described pontoon has the disadvantage that the end part has prohealthcare form, causing significant water resistance and instability on the course when towing.The technical result of the invention is the provision of safe towing and ease of use. It is achieved by the fact that in salvaging the pontoon, comprising a housing with a system for creating lift and towing eyebolts are installed, one of the extremities of the hull of the pontoon is provided with a detachable fairing in the form of a cone consisting of petals, one end of which is its length to the perimeter of the mentioned end of the pontoon with fixation in a predetermined position, this tape has holes to accommodate them in tow Obukhov when installing it on the extremity of the hull of the pontoon and mounting delays.In Fig. 1 shows a General view of the removable cone of Fig.2 attached to the pontoon removable cone.Fairing 1 consists of the nasal element 2, the hinges 3, through which the petals 4 are fixed to the narrow end, to the nasal element 2. The wide ends of the petals 4 attached to the belt 5, consisting of tape 6, one end of which has a latch 7 which enables the change of the length of tape and. fixing in a predetermined position. The tape has holes 8 are attached to the towing butt 9 of the pontoon 10, and guy wire 11 is fixed, for example, to kontopodis the eyebolts are installed 12.Work is carried out as follows.Hold the fairing 1 at the end portion of the pontoon 10, tape 6 cover the perimeter of the pontoon 10 so that the towing butt 9 seated in the bore 8 of the tape 6. With the release of the 7 tape 6 fits snugly over the pontoon 10 along its perimeter and braces 11 is fixed in a predetermined position for contone butt 12. Mustache towing Braga 13 are fixed to the tow 9 eyebolts are installed, not letting them out of the holes 8. The pontoon is ready for towing.

Middle section is provided with stop and is movably connected with longitudinal guides of ramp by means of rollers located on upper edge of shield and is rotatably connected by means of connecting rods articulated at one end to lugs on rear plane of middle section; at other end provided with tubular head it is articulated to axles found on side walls of ramp.
EFFECT: facilitated action of crew in handling the collapsible shields during ferry crossing; reduction of time required for loading the equipment on and unloading the equipment from ferry.
SUBSTANCE: invention relates to collapsible floating docks of adjoining water area and coastal structures. The proposed dock features a cellular design and consists of the hexagonal floating modules made from a composite material, consisting of polyurethane enclosure and compacted foamed plastic fitted there inside. Detachable fasteners represent horizontally located plates jointed by vertical rods. Aforesaid plates feature teeth bent towards the module and conic recesses made at the plate centre to receive the rod heads. A part of floating modules features recesses for mooring floating means. Note that the dock is equipped with detachable hand-rails with fasteners.
EFFECT: expanded performances, higher strength, stability and buoyancy.

SUBSTANCE: invention relates to water crafts and aims at expanding operating performances of tanks and armored personnel carriers. Water craft comprises two water-permeable onboard pontoons, fixed on armored vehicles by means of front and rear fasteners. It comprises also wing to create a wing to create lifting force from ingoing water flow and to direct it to under armored vehicle rear is arranged between pontoons ahead of vehicle and fixed on its inner sides. Water craft incorporates also stern inserts. Aforesaid wing can be installed in various positions with respect to height and angle of attack. Sharp stem pontoon comprises tank and smooth executed ship contours. Pontoon stern features L-like widening along inner side. Flat bottom features smooth transition to wedge-like uprise towards stem and stern. Outer side bilge is rounded off. Pontoon stern has to accommodate water propeller and rudder-stabiliser. Note that water craft is furnished with emergency suspension to push off if stern fastener gets broken.
EFFECT: expanded performances.

SUBSTANCE: invention is related to the field of construction, modernisation and reconstruction of port berths. Method is characterised with formation of mooring wall in the form of raft from several layers of multifunctionally used tight pipelines of various diametre, which are manufactured as helical-seamed and multilayer from composite set of materials. Wall is produced by two groups of technological tight pipelines laid on water surface in direction of its formation, which are joined to each other in each group with the help of coaxial stiff transverse ribs with development of two pontoons. Adjacent ends of ribs are joined to each other with the help of hinged joints, along axis of which the first of bearing pipelines is laid, and a pair of joined pipelines of the second layer is laid on top, and so on till rated level. Functional pipelines are laid onto the last horizontal layer of bearing pipelines, and composite elements of hatches and working surface fixed with tension to anchor ropes are mounted on functional pipelines. Internal volumes of upper - subsurface layer of pipes are equipped as functional premises: warehousing, technological, working premises. Railway track and motor road, which are joined to according ground transport network, are laid on surface of mooring wall.
EFFECT: invention makes it possible, as a result of elimination of earth works related to dredging, to reduce capital, material and financial costs in case of port mooring part enlargement, and also to reduce construction time.
