GE Power Conversion completes its portfolio for marine applications with GE's SeaJetTM Pod.
GE's SeaJetTM Pods are podded propulsion units, in which the electric motor is housed in the hull mounted pod and directly connected to the propellor, liberate cargo space and improve maneuverability/efficiency.
GE's technology is driven by MV7000 PWM drives with a range from 2.5MW to 22MW for various types of vessels, offering flexibility in machinery and vessel arrangement and excellent maneuvering capability. With a customized and focused design, improved performance can be achieved for each individual vessel.
Solution & Scope
SeaJetTM is designed to enhance maintainability and availability and to meet marine rules and IEC standards. It includes induction motor technology that has demonstrated its robustness through a wide range of experience in Naval Merchant and Offshore applications.
GE's induction motor is smaller and features a bilateral cooling system. The ability of the MV7000 PWM drive to operate at very low frequency allows the motor pole number to be optimized and a low resistance squirrel cage designed to increase efficiency and power factor.
- SeaJetTM is available for ice going vessels up to icebreaker 7 ice notation with a power range from 7.5MW to 15MW
- SeaJetTM is also compatible with transformerless solution, Hybrid variable AC network and Energy Storage DC/DC converter
