Abstract
A marine vessel which includes a bow section, a stern section and a mid-section, wherein the bow and stern sections are of different hull construction from that of the mid-section which has a curved outer shape; the skin of the hull of the bow and stern sections are preferably made of hybrid composites while the port and starboard sides of the mid-section are of hybrid composites supported on the inside thereof by a light framing to transmit pressure loads; the mid-section further includes an inner section that may be of box beam construction or longitudinal bulkhead construction.
Claims19
A ship hull construction with a low-block coefficient for a marine vessel, comprising a bow section, a mid-section with a substantially tumblehome shape and a stern section, in which the cross-section has a curved outer shape in the longitudinal direction so that, as viewed in transverse cross section, the mid-section becomes smaller toward the bow and stern sections, and includes an inner section with one of framing means and longitudinal bulkhead means, said hull construction having outer shells made of composite materials.
A marine vessel comprising a bow section, a mid-section and a stern section, in which the mid-section has a curved outer shape and includes an inner section with one of framing means and longitudinal bulkhead means, said hull construction having outer shells supported on the inside thereof by a stainless steel light framing stiffener means for transmitting pressure loads, and the stiffener means being connected with a respective outer shell of the mid-section by way of an elastomer and a fastening assembly that includes a stainless steel bolt embedded in the composite material of the respective outer shell that cooperates with a high strength spring prestressed by a nut.
A marine vessel, comprising a hull having a low block coefficient and including a bow section, a mid-section and a stern section, in which the starboard and port sides of the mid-section have outer shells of hybrid composites with light framing on the inside thereof, and in which the mid-section has a curved outer shape in the longitudinal direction so that, as viewed in transverse cross section, the cross-section becomes smaller toward the bow and stern sections, and includes an inner section with one of framing means and longitudinal bulkhead means.
A marine vessel comprising a bow section, a mid-section and a stern section, in which the mid-section has a curved outer shape and includes an inner section with one of framing means and longitudinal bulkhead means, the mid-section including an inner section having upper and intermediate decks of metallic sandwich construction with a core of metal foams, stainless steel microtrusses, folded plates or honeycomb.
