Shipbuilding / Vessel Construction
Shipbuilding is the construction of ships, which takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, are workers which specialize in vessel construction and repair. The construction of boats is called boat building. 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.
Block construction is a modern shipbuilding method which involves the assembly of prefabricated sections. 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. Some of the more equipped shipyards are able to build equipment and utilities into the blocks, pre-installing pipes, plumbing, and electrical cables. The more components that can be built into the blocks before final assembly, the less effort required once the hull is welded together.
Since the 40s, modern ships have been made of welded steel. The first ships produced by this method had problems with inadequate fracture toughness, which let to rare but devastating structural cracks. 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. This problem seems to result when steel with unknown toughness or FATT (fracture appearance transition temperature) is used in side shells. Despite these occasional incidents, most problems with brittle fractures seem to have been eliminated my modern methods and regulation.
Depending on design and materials, vessels reach a point in their lifespan where refitting and repair become impractical or impossible. The demolition of ships is called ship breaking- a process designed to allow materials and components to be reused and recycled. 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.
Evac's complete wastewater system is onboard MT João Cândido, the first Suezmax tanker recently delivered by Atlântico Sul Shipyard (EAS) for Transpetro. Evac was selected for the first series of ten 160,0000 dwt Suezmax tankers and for the series of five 110,000 dwt Aframax tankers, also being built by Atlântico Sul Shipyard, the largest and most modern shipyard in Brazil.
As part of the National Shipbuilding Research Program’s (NSRP) core mission to reduce the costs associated with Navy shipbuilding and repair, the NSRP Executive Control Board has selected 15 new research and development projects for award, totaling approximately $1.4M. These projects will be executed under the 10 NSRP communities of practice referred to as panels:

Huntington Ingalls Industries said that its Newport News Shipbuilding (NNS) division hosted a visit by Susan Ford Bales, daughter of the late President Gerald R. Ford and sponsor of his namesake ship.
Bales received a briefing on Gerald R. Ford's (CVN 78) construction progress since her last visit in August 2010. Following the briefing, Bales toured Ford with shipyard leadership, ascended NNS' 1,050-metric ton crane to get a bird's-eye view of the shipyard, and had lunch with CVN 78 shipbuilders.
