First Azipods for Oldendorff transhipment units
Oldendorff carriers has ordered two transhipment vessels from Chengxi Shipyard in China for operation in Vietnam, each propelled by 2 x 1.9MW Azipod units. The order represents the first reference for ABB's Azipod propulsion technology from the bulk carrier segment.
The 21,500 dwt vessels will feature 2 x Azipod® CZ0980 1.9MW propulsors. The order represents the first foray for ABB’s electric podded propulsion into the dry bulk carrier segment. Matti Nuuttila, sales manager for cargo vessels, ABB Marine & Ports, said: “We see this project as a great milestone that heralds a new era of electric propulsion for special purpose bulker vessels.”
The newbuild self-unloading dry cargo transhipment units will, upon delivery, operate in Vietnam. The TSVs have been designed to operate in the shallow waters off Nghi Son. Each vessel will be 145m-long and 34m-wide, with an 8.5m draft.
Each TSV will be fitted with two heavy-duty cranes for self-loading from the Capesize vessels, and a gravity feed self-unloading system for coal unloading at the jetty. The vessels also feature twin 1100 kW bow thrusters.
The newbuild vessels are developed by Shanghai-based CS Marine design company together with Oldendorff Carriers. Both vessels, due for delivery in 2021 from the Chengxi Shipyard in China, will be equipped with a complete power and propulsion solution from ABB.
ABB will also supply a wide range of electric, digital and connected solutions, including main diesel-electric power plant, generators, bow thruster motors, transformers, switchboards and the power management system for propulsion and cargo handling.
ABB noted that adopting ABB’s advanced energy management system had permitted the number of generator sets to be decreased from four to three units. The vessels will be able to use shore power while carrying out the unloading operation at the jetty.
“The choice of Azipod electric propulsion system has reduced the investment costs dramatically as the vessels are already equipped with high power generation required for self-unloading and loading cargo handling,” said Jan Henneberg, newbuilding manager, Oldendorff Carriers.
Oldendorff Carriers signed a 25-year contract in 2018 to supply transport and transhipment services to a new thermal power station under construction in northern Vietnam, Nghi Son 2. The new power station is expected to consume up to 4 million tonnes/year of predominantly Indonesian steam coal once it ramps up to full production in mid-2022.
The power station is located close to an existing thermal power station, Nghi Son, and an oil refinery and petrochemical complex. The navigation channel to the jetty has not been dredged to a sufficient depth for Capesize vessels, necessitating the adoption of an offshore transfer strategy, and unloading at a jetty.
Once in operation, the vessels will be among over 1,000 ships connected to ABB Ability Collaborative Operation Centers using the ABB Ability Remote Diagnostic System, which deploys sensor-driven onboard monitoring software that integrates with analytics ashore.
