CLIENT: P. T. FREEPORT INDONESIA, JAKARTA

VESSEL BUILT AT: KEPPEL SINGMARINE PTE. LTD., SINGAPORE

CLASSIFICATION SOCIETY: ABS

In 1998, a large pusher-barge fleet to be used for a big-scale LIGHTERAGE service was delivered from a Singaporean shipyard to P. T. Freeport Indonesia, Jakarta.  All the vessels of this fleet, classed with ABS, were built at Keppel Singmarine Pte. Ltd., Singapore to the designs of Navnautik Pte. Ltd., Singapore.  The fleet was planned to load copper ore concentrate from the mine in West Irian, Indonesia, at the port of Tembagapura, south coast of West Irian, aboard of a bulk carrier moored several miles off the shore.

The barge is a covered deck-loading barge of 15,000 DWT equipped with self-unloader system supplied by BMH Marine AB, Sweden.  A combined coal/oil barge equipped with BMH self-unloader system belongs to the fleet for supply of fuel to the mine and the loading site.  The pusherboats, Tembaga 3 and 4, are powered with two Caterpillar 3606, each developing 2,300 KW at 1,000 RPM, to drive Schottel Rudderpropellers SRP 2020.

As the coupler systems organizing the “Fleet”, Taisei Engineeering’s 2-pin supporting articulate couplers of combined friction- and tooth-engagement type, ARTICOUPLE FRC-300E, were adopted with successful results, because the site of transhipment is fairly rough in the rainy season and connection at the side of the bulk carrier under the influence of waves was expected.
