VESSEL REVIEW | Haixun 10765 – Electric patrol boat to be deployed on China's Li River

The China Maritime Safety Administration (CMSA) recently placed a new patrol vessel into service.

Haixun 10765 (海巡10765) was designed for operation in inland waters, where it will conduct patrols and search and rescue (SAR) missions.

The vessel has an LOA of 23.98 metres (78.67 feet), a beam of 5.1 metres (17 feet), a draught of only 0.5 metre (1.6 feet), a depth of 1.35 metres (4.43 feet), a deadweight of 100, and space for up to 20 rescued survivors in addition to the crew.

Built for long-endurance patrols

Power is provided by two 548kWh lithium iron phosphate battery packs that drive two 90kW permanent magnet motors connected to azimuthing thrusters to deliver an operational speed of 11.8 knots and a maximum endurance of 14 hours.

The vessel can still sail up to five hours on fully charged batteries even at high speeds. This then translates into patrols of extended duration without generating noise and pollution that could otherwise affect nearby communities and the surrounding marine environment.

Agile and durable endurance platform

Calculations have shown that the vessel can save up to 140 kg of fuel per voyage as well as reduce CO2 emissions by as much as 440 kg. To further reduce environmental impact, the vessel utilises eco-friendly paint.

The thrusters also allow the vessel to turn on its own length, an important attribute during berthing/unberthing, manoeuvring alongside other vessels, and navigating through narrow areas.

An integrated control system combines the functions of energy management, propulsion control, as well as monitoring of vessel parameters.

Haixun 10765 will be operated by the CMSA branch primarily responsible for the Li River. The vessel is therefore optimised for the unique hydrographic conditions of that specific waterway.
