There are a lot of construction machinery models

Ocean engineering machinery is actually adapted from the works dedicated ship, so exactly defined, should be called engineering vessels, as water engineering construction equipment for Concrete batching plant in inland and ocean above. Also the type of ship construction are more functional use and land-based construction machinery like. For example, the land on excavators, sea have dredger; land with cranes, crane at sea there (commonly known as the floating crane); land with hammers, offshore boats are piling; land there Pipelayers, sea have Lifting pipelay vessel; Concrete mixing plants on land, at sea with concrete mixing vessel; land on flatbed trailers and offshore tugs and barges have; There are also some special-purpose engineering vessels, such as fishing boats, fire boats, icebreakers , tender (supply of fuel and fresh water), shipwreck lifeboat, research ships, boats and military engineering cabling vessels.
