INVT GD350-CCS VFD for Ship Cable Winding and Unwinding

Ship cables are a crucial part of ship mooring, ship operations, marine rescue, transportation and hoisting operations. However, due to changes in tides and draft during loading and unloading, the tightness of the tied ship cables will also change. The traditional method requires sailors to adjust the tightness of the cables in time to prevent the cables from coming off the piles and causing the ship to drift, which not only wastes crew resources but also brings insecurity.

In recent years, the shipbuilding industry has entered a fast lane of development. In the past, the winding and unwinding of cables were adjusted manually, but now the variable frequency direct drive solution can be used to replace manual work. When the cable load changes, the variable frequency drive motor maintains a constant torque to achieve the effect of cable reeling and unreeling at a constant speed and torque.

Inverter replaces traditional power frequency, INVT provides better user experience

INVT GD350-CCS series VFD solution has CCS certification and excellent asynchronous motor open-loop vector motor control algorithm. It can simultaneously realize multiple functions such as speed mode, torque mode, motor brake logic control, etc., so that the cable remains taut and will not be broken .

* NVT VFD avoids the cumbersome electrical wiring of relays and contactors, and has powerful protection functions, with obvious advantages in electrical wiring and safety.

* GD350-CCS is equipped with an excellent open-loop vector motor control algorithm, which can achieve constant torque output of the zero-frequency motor. The cable can always remain taut without shaking or stalling.

* It supports free switching between speed and torque modes, and with the unique brake release control logic, the control is simpler and more stable.
* It has independent heat dissipation duct and compact size, which meets the design requirements of small cabinets and saves costs.

Ensure safety  and  Improve efficiency
* Safety: Real-time measurement of the cable tension status reduces the possibility of human misjudgment and missed judgment, and improves the safety of ship operations.

High efficiency: The inverter is used to replace the traditional contactor control and manual adjustment, and the cable tension is automatically controlled to improve the work efficiency and stability.

Reduce costs: The frequency conversion solution effectively reduces the loss of motors and cables, saving labor and material costs.

Long life: GD350-CCS has strong resistance to current shock, thick coating, and can withstand salt spray environment. The design life is more than 10 years.

INVT entered the offshore engineering industry through Zhenhua in 2009, working hard in key areas such as technology and materials to explore innovative solutions.

In addition to the above solutions, INVT continuously innovates its products and solutions in the crane vessel, anchor winch, fan and water pump industries, and is committed to providing more professional, meticulous, and value-for-money products and services for the sustainable development of the industry, making customers more competitive.
