GE Vernova’s Power Conversion is showcasing at CANSEC in Canada its SeaJet range of podded propulsion systems, which, the company says, brings efficiency and maneuverability to operate in harsh sea ice conditions. 

Power Conversion is now launching SeaJet power range from 1.5 MW to 4 MW, using low voltage (<1000 V) ideal for smaller ships.  

"With high steering capability, SeaJet provides very good transit and bollard pull performance. Powered by proven technology, including Power Conversion’s SeaPulse low voltage DC drive system and a high torque-density Advanced Permanent Magnet Motor (APMM), the pod eliminates the need for hydraulic systems, thanks to the integration of an electric steering system with electrical actuators and intelligent control system, enhanced cooling system, Eco-sealing technology and advanced bearing technology in a compact package. The system also embeds Power Conversion’s digital Asset Performance Management (APM) technology, helping to enhance availability, reliability and maintainability," GE Vernova said.SeaJet pod 4 MW ©GE

According to GE Vernova, the benefits of SeaJet for owners and operators include increased propulsion system efficiency, reduced total installed power generation, reduced total fuel consumption and exhaust emissions, reduced noise and vibration levels and enhanced maneuverability.  

For shipyards, the benefits include flexibility in machinery arrangement with fewer components, a simplified hull form through the elimination of shaft lines and rudders, and reduced equipment installation time and cost.

Moises DelToro, Marine Leader for North America at Power Conversion, explained: “There is increasing investment in polar exploration and arctic routes for shipping but also in polar region protection. The first-generation pods produced by GE Vernova have demonstrated their robustness across naval, merchant and offshore applications for decades, and the new generation is gaining traction with owners building Arctic tonnage that require rugged, ice-class performance.”

DelToro continued: “SeaJet will play a key role in serving this growing demand, including new applications such as expeditionary passenger vessels.”
