Heavy-lift ship
A heavy-lift ship is a vessel designed to move very large loads that cannot be handled by normal ships. They are of two types:
History[edit]
In the 1920s, the Bremen-based shipping company DDG Hansa saw a growing demand of shipments for assembled locomotives to British India. That led to the construction of the world's first heavy lift vessel, SS Lichtenfels with a 120 t (118 long tons; 132 short tons) derrick.[11] After World War II, DDG Hansa became the world's largest heavy lift shipping company. In terms of lifting capacity it reached its peak in 1978 with refitting the Japanese-built bulk carrier MV Trifels with two 320-tonne (315-long-ton; 353-short-ton) Stülcken derricks. Shortly after that, in 1980, DDG went bankrupt. With that, only the Dutch shipping companies Jumbo, BigLift Shipping (until 2001 named Mammoet Shipping) and SAL Heavy lift[12] were left as heavy lift shipping specialists.
