Abstract
The present invention concerns a bulbous bow for a sea-going vessel, said bow comprising a load-carrying inner structure mounted at the stem of the vessel and an outer shell structure defining the hydrodynamic properties of the bulbous bow, wherein said outer shell structure is provided with a sub-structure for replaceably mounting on the inner structure. The invention further concerns a seagoing vessel comprising such bulbous bow as well as a method of producing a bulbous bow and a method of mounting or replacing a bulbous bow.
Claims21
A bulbous bow assembly for a sea-going vessel, said bulbous bow assembly comprising:
- a load-carrying inner structure mountable at a stem of the sea-going vessel, the load-carrying inner structure having a protruding member adapted to be mounted on a bulkhead of the sea-going vessel;
- and
- an outer shell structure defining the hydrodynamic properties of the bulbous bow assembly, wherein said outer shell structure is provided with a sub-structure for replaceably mounting on the load-carrying inner structure, said outer shell structure being received on said protruding member.
A method of producing a bulbous bow assembly for a sea-going vessel:
- said bulbous bow assembly comprising:
- a load-carrying inner structure mountable at a stem of the sea-going vessel, the load-carrying inner structure having a protruding member adapted to be mounted on a bulkhead of the sea-going vessel;
- and
- an outer shell structure defining the hydrodynamic properties of the bulbous bow assembly, wherein said outer shell structure is provided with a sub-structure for replaceable mounting on the load-carrying inner structure, said outer shell structure being received on said protruding member:
- the method comprising manufacturing at least the outer shell structure using rapid prototyping by means of 3d printing.
A method of mounting or replacing a bulbous bow assembly comprising:
- providing a bulbous bow assembly comprising:
- a load-carrying inner structure mountable at a stem of the sea-going vessel;
- and
- an outer shell structure defining the hydrodynamic properties of the bulbous bow assembly, said outer shell structure provided with a plurality of modular sections including an outer shell and a sub-structure for replaceably mounting on the load-carrying inner structure;
- storing at least part of the outer shell structure on-board the vessel;
- and
- lowering at least one part of the outer shell structure into the sea for mounting on the vessel.
A bulbous bow assembly for a sea-going vessel, said bulbous bow assembly comprising:
- a load-carrying inner structure mountable at a stem of the sea-going vessel, the load-carrying inner structure having a protruding member adapted to be mounted on a bulkhead of the sea-going vessel;
- and
- an outer shell structure defining the hydrodynamic properties of the bulbous bow assembly, wherein said outer shell structure is provided with a plurality of modular sections including an outer shell and a sub-structure for replaceably mounting on the load-carrying inner structure, said outer shell structure being received on said protruding member.
