SEAJET™
GE Power Conversion completes its portfolio for marine applications with SEAJETTM Pod*.
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.
SEAJETTM Pods are 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.
Configurations
- 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
SEAJET is a trademark of GE Energy Power Conversion France SAS.
*The ice-class range of SEAJETTM is a joint technology development with AETC Sapphire.
