Transhipment

CSL Asia operates and commercially manages the revolutionary Sea Spider Transhipper (“SST”), SST Berau, located 20 kilometers off the east coast of Kalimantan, Indonesia at the Muara Pantai anchorage, tranships in excess of 3.5 million tons of coal annually for our customer under a long-term contract. The SST Berau was designed to enable the customer, restricted by a shallow draft river system and port, to load Panamax and Cape-size vessels and access the international coal market. The semi-submersible platform was adapted from the offshore oil industry where it is considered the most stable floating platform in waves. The SST Berau employs the SWATH (Small Waterplane Area, Twin Hull) concept and has several advantages over traditional barges. Because it is semi submersed, it is much less vulnerable to waves, which is critical due to the length of the loading boom as the motion of the barge or platform is magnified significantly at the end of the boom. Another major benefit of the SST is that it allows barge unloading from the center of the barge outward as most coal is loaded in the center of the barge this keeps the coal barges stable throughout unloading. The SST’s effective transhipment rate is 1,200 metric tons per hour.

In 2009, CSL Asia, together with its partners P.T. Andhika Lines commenced operation of another transhipment platform for our Indonesian customer. This new platform is designed to tranship up to 6.0 million tons of coal annually at rates in excess of 1,250 tons per hour. The FOTP Derawan is a third generation transhipment design reflecting the best attributes, design and technology found on our previous transhipment projects. The Derawan is co-located with the SST Berau.
