Shipyards Adapt to help Navy, Coast Guard Recapitalize Fleets Equipment can often be reused in other ships, and metals (particularly steel) are separated for scrap recycling, with the hulls being discarded in ship graveyards. The demolition of ships is called ship breaking- a process designed to allow materials and components to be reused and recycled. Despite these occasional incidents, most problems with brittle fractures seem to have been eliminated my modern methods and regulation.ĭepending on design and materials, vessels reach a point in their lifespan where refitting and repair become impractical or impossible. This problem seems to result when steel with unknown toughness or FATT (fracture appearance transition temperature) is used in side shells. The development of specialized steel in the 50s has largely eliminated the problem of brittle fracture, although there are still instances due to the unregulated use of grade A and B steel.
The first ships produced by this method had problems with inadequate fracture toughness, which let to rare but devastating structural cracks. Since the 40s, modern ships have been made of welded steel. The more components that can be built into the blocks before final assembly, the less effort required once the hull is welded together. Some of the more equipped shipyards are able to build equipment and utilities into the blocks, pre-installing pipes, plumbing, and electrical cables. Cross-sections of the superstructure are pre-built in a shipyard, taken to the building dock (or slipway,) and then hoisted into position and attached.

Due to the smaller size and scope of the vessels being produced, boats do not necessarily require the full services of a shipyard but may be built in a boatyard or even smaller private facility.īlock construction is a modern shipbuilding method which involves the assembly of prefabricated sections. The construction of boats is called boat building. Shipbuilders, also called shipwrights, are workers which specialize in vessel construction and repair. Shipbuilding is the construction of ships, which takes place in a specialized facility known as a shipyard.
