S. Korea showcases cost-cutting mobile harbour

BUSAN, South Korea — South Korean researchers Wednesday showcased an invention which they claim could transform the shipping industry -- a harbour which goes out to a ship.The Mobile Harbour, a giant barge with a shallow draught and a stabilised crane, was put through its paces off the southern port of Busan as journalists and diplomats looked on.The harbour, designed by the Korea Advanced Institute of Science and Technology (KAIST), is intended to unload big container ships in open waters to eliminate costly delays which shippers face to use crowded ports.Because it only needs a limited depth of water the harbour does not have to unload at a regular container dock. It can ferry containers closer to their final destination, reducing the cost and pollution of road transport.The mobile harbour can also be used for salvage and rescue operations at sea, for building and maintaining offshore plants and for supplying ships moored in deep waters, KAIST said."Today's demonstration of the Mobile Harbour's core technologies will really change the face of our maritime transportation system," said Kwak Byung-Man, director of KAIST's Mobile Harbour Centre."It will be able to deliver more goods to global markets and consumers via sea routes, not necessarily building more ports or expanding existing harbours."The new system will also significantly cut the high cost of overland cargo transport and reduce carbon emissions, he added.KAIST said the project, initiated in 2009, was a result of "thinking outside the box" -- why could a harbour not sail to a ship instead of vice versa?But this was easier said than done.Researchers from KAIST, companies and other local universities had to overcome daunting technical challenges in the $32 million project bankrolled by the government.Connecting two vessels of widely different sizes in heaving seas was one problem, and stabilising the crane mounted on the mobile harbour was another, said KAIST professor Kim Kyung-Soo."The Mobile Harbour is a very complicated, integrated system back
