The battery pack of the "Ningbo Port Towboat 80" Vessel, the first hybrid oil-electric towboat in China, and owned by the Ningbo Oil Port Tug & Barge Co., Ltd., was recently charged with 1,600 kWh of electricity through the intelligent shore power system of the working ship located at the Beilun Working Ship Terminal. Under full power operation, it only takes about 2 hours to get fully charged. This marks the official launch of Ningbo Zhoushan Port's first intelligent shore power system for working vessels.

"With this system, our tugboats can unleash strong electrical energy and make ports cleaner and more environment-friendly." Zhao Zhongyi, Captain of the "Ningbo Port Towboat 80" Vessel, praised the newly put into use intelligent shore power system for the working vessels. The system was independently invested and constructed by the Ningbo Oil Port Tug & Barge Co., Ltd., covering one 2,100 kVA box-type substation, one integrated low-voltage charging pile, high-voltage cables, and other supporting equipment. It was completed in October 2023.

"Among them, the intelligent level of the high and low voltage switchgear selected by the system is leading in the industry. It can not only monitor the electricity consumption in real time, but also automatically detect faults through remote monitoring and synchronously feedback to the cloud network." The person in charge of the company said. This system can achieve the goal of fully charged battery pack for the first oil-electric hybrid tugboat "Ningbo Port Towboat 80" Vessel in China, efficiently ensuring the operational needs of the vessel.

"The cost of electricity does not exceed 1 yuan per kWh, which can save a lot of costs compared to fuel." After the first operation of the "Ningbo Port Towboat 80", Captain Zhu Yujun calculated a green environmental protection account.

Towboats assisted berthing is related to port safety production, and the company is the main force of towboat assisted berthing in the Ningbo Port area. The relevant person in charge of the company said that the implementation of the intelligent shore power system for the working vessels is a key breakthrough in achieving the low-carbon goal of towboat power. According to calculations, the annual electricity consumption of the "Ningbo Port Towboat 80" Vessel is expected to exceed 640,000 kWh, which can reduce diesel consumption by about 200 tons and carbon emissions by about 600 tons per year.
