摘要:
A floating connection assembly of a bulkhead to at least one element of constraint includes a projection integral to the element of constraint and at least one first longitudinal sealing bead. At least one projecting element protrudes from the bulkhead. The assembly has at least a second flexible seal and at least one closure plate, arranged in such a way that the bulkhead and the element of constraint are separated along an edge of the bulkhead. The one first longitudinal sealing bead is interposed between the bulkhead and the projection, on which is present at least one through hole through which passes the projecting element, integral with a respective closure plate, so that the bulkhead remains cantilevered on the protrusion, avoiding a different support, and so that the projecting element is free to oscillate inside the hole.

A cargo hold structure for an oil tanker is provided, in which a plurality of vertical webs that is mounted on longitudinal bulkheads of the cargo hold in a height direction of a hull is made wide and horizontal girders which connect the vertical webs to each other and support them, thereby controlling the sloshing load of the cargo hold and improving the structural strength of the cargo hold without having to mount crossties. The cargo hold structure includes a longitudinal bulkhead (20) arranged in a lengthwise direction of a hull to divide an internal space, a plurality of vertical webs (22) coupled onto the longitudinal bulkhead (20) in a height direction of the hull, the vertical web (22) having a width of 0.15 to 0.20 times the total height (H) of the cargo hold, and a horizontal girder (24) arranged between the vertical webs (22) in the lengthwise direction of the hull, the level of the horizontal girder (24) being within 30% to 60% of the total height (H) of the cargo hold from the bottom thereof.

摘要:
A rotationally molded article, preferably a boat or equivalent floatable marine structure, has a compressible truss structure either assembled to the mold and molded into the internal structure of the article, or added to a previously molded article and permanently attached in place. The compressibility of the truss accommodates key challenges to molding articles of large dimension without encountering buckling or twisting or other structural defects. For example, when molded integrally with the article, the compressible truss compresses as the thermoplastic material shrinks slightly during cooling. When added to a previously molded article, the compressible truss allows the article to withstand extreme amounts of applied force during use, e.g., encountering high waves in boats of seven meters [23 feet] or greater at speeds of at least 20 knots [37 km/h (or 10.3 m/s)].

摘要:
An integrally moulded plastic boat hull structure is provided with a plurality of threaded inserts for securing associated boat components. Each of the threaded inserts is moulded into the boat hull structure with a force dissipating planar member which directs the localized forces away from the threaded insert to an enlarged boat hull region proximate the threaded insert. By spreading the load over a greater region, a highly localized load point is avoided.
摘要:
A water-going vessel propelled via a plurality of parallel sets of two underwater turbines disposed along the underside of said vessel, with each turbine mounted on respective retractable struts. A plurality of sets of turbines extend from respective turrets disposed along the longitudinal midline of the underside of the vessel, each of said turrets rotatable through 360 degrees and each having extending therefrom one turbine set. Hull construction pieces of the vessel preferably comprise an outer and an inner containment wall within which a plurality of touching hollow spheres are sandwiched and wherein a plurality of individual lengths of high strength sheaths are within respective tubes which are parallel with the containment walls and disposed within intrices formed by the spheres. The individual lengths of sheaths are connectable to each other to form a network of sheaths encircling the hull. Stress can be introduced and adjusted within each length of sheath which is a part of the network. Also disclosed is an improved underwater turbine, wherein the improvement comprises a plurality of housings surrounding respective portions of the turbine, with each of said housings having therein rotatable blades and, immediately rearward of said blades, a plurality of nozzle openings through which a gas under pressure can exit in a path of flow directed along the outer wall of said turbine.
