Lighter. Hong Kong Harbour.
A lighter is a type of flat-bottomed barge used to transfer goods and passengers to and from moored ships.
Hong Kong widely uses lighters in midstream operations whereby lighters transport cargo, mostly containers, between oceangoing vessels or to and from terminals. Lighters in Hong Kong are usually equipped with cranes of 40-60 tonnes capacity, and the largest ones can carry up to 300 TEU containers (empties). Lighters are not fitted with engines but are towed by tugboats. In 2007, midstream operators handled about 2 million TEUs and 5 million TEUs were transported as river trade cargo which are heavily dependent on lighters. Original public domain image from Flickr
