Variable-Frequency Control System for Main Engine Cooling Seawater Pump
The variable-frequency, energy-saving system for the main engine cooling seawater pump is a prime example of “refined energy management” on ships. By shifting from the conventional “extensive,” constant-flow cooling approach to an intelligent, demand-based regulation strategy, it achieves:

Shaft-Driven Generator PTO/PTI/PTH Hybrid System
The shaft-driven generator PTO/PTI/PTH hybrid system represents the future direction of modern marine propulsion systems. It moves beyond the traditional, isolated paradigm of “the engine propels the vessel while the generator produces electricity,” instead treating the ship’s mechanical and electrical power as an integrated energy system that can be optimally managed. Its core attributes are flexibility and efficiency: through intelligent energy-management strategies, it automatically selects the optimal operating mode to meet varying navigation demands, thereby achieving the comprehensive objectives of energy conservation, emission reduction, cost containment, and performance enhancement. This system is particularly well suited for vessel types with stringent requirements for operational efficiency and environmental performance, such as container ships, LNG carriers, cruise ships, and ro-ro vessels.

Variable-Frequency Control System for Offshore Work Vessels
The variable-frequency control system for offshore operation vessels is a highly complex, highly integrated, intelligent electro-hydraulic system. Its key features can be summarized as follows: leveraging a diesel–electric common power grid as the platform, employing networked integrated control as the nervous system, and relying on high-reliability redundant design for assurance; utilizing vector control and advanced algorithms to achieve precise torque, speed, and position control; and ultimately meeting the stringent demands for operational efficiency, safety, and energy conservation and environmental protection under a wide range of harsh operating conditions.

Main and Side Thruster Drive and Remote Control System
The main and side thruster variable-frequency control system is the “soul” of modern, intelligent ships. It converts the powerful output of electric motors into precise, smooth, efficient, and reliable vessel maneuverability, delivering a revolutionary improvement whether for the long-distance oceanic voyages of giant vessels or for the delicate “needle-in-a-haystack” operations within ports.
