A new series of inland waterway tugs is being built in Indonesia as part of the booming shipbuilding industry in the southeast Asian nation
An Indonesian shipyard is building a series of new-generation shallow draught tugs for a key barge support project, demonstrating a resurgence of vessel building in the country.
PT Patria Maritim Perkasa is constructing the tugs in Batam for PT Patria Maritime Lines, which is expanding its barge operations in South Kalimantan, Indonesia.
These tugs are being built by the subsidiary of PT United Tractors Pandu Engineering, to an OSD-IMT7402 design for operations on the Barito River, out of Banjarmasin, Indonesia.
The first of this series, Patria 22, was delivered in August. It is being used to tow, push, berth and undock 91.4-m barges in water depths as low as 2.5-3 m. At least two more of these tugs will be built, with options for more if required.
Because of the shallow waters of the river in the dry season, the tugs were designed with draughts below 2 m.
Patria 22 has an overall length of 23 m and accommodation for 10 people, arranged in two quadruple and two single cabins. It has two main diesel engines, each developing 618 kW of power driving conventional fixed propellers with high-efficiency nozzles.
This configuration provides Patria 22 with an ahead bollard pull of 20 tonnes and a free running speed of around 12 knots. Patria 22 is Indonesian flagged and classed by Bureau Veritas.
This OSD-IMT designed tug is fitted with a towing hook aft. Its pusher bow has a triple vertical D-fender integrated into the vessel’s structure.
Other Indonesian shipyards are building harbour tugs for domestic ports and for export orders with deliveries scheduled for Q4 2020 and 2021.
According to BRL Shipping Consultants, there are at least 18 tugs under construction as of 15 October at Indonesian shipyards for delivery in the next 14 months.
Alusteel is building four harbour tugs, each with 1,540 kW power, for an unnamed domestic owner and United Sindo Perkasa is producing three harbour tugs for Rawabi Vallianz Offshore Service, each with 2,900 kW.
Batamec is building two harbour tugs with 2,740 kW, PT Cahaya Samudra is constructing two with 1,240 kW of power and PT Orela Shipyard is producing two tugs with 2,810 kW – all for unnamed Indonesian owners.
Pertamina has three 2,740-kW tugs on order, two at PT Dumas Tanjung Perak and one at PT Daya Radar Utama. PT Graha Trisaka Industri is providing two escort tugs for CPC Corp’s terminal in Taiwan.
