GE’s Marine Solutions has been selected by ASMAR Shipyards to provide an integrated marine propulsion system for the Chilean Navy’s new Polar class icebreaker vessel, the company announced on 1 March.

The vessel will support the navy’s Antarctic operations for search and rescue missions, scientific research, logistic support and resupplying bases in the Chilean Antarctic Territory.

The Chilean Navy’s 110m vessel will be equipped with GE’s full marine propulsion system to power and propel the vessel, including diesel electric propulsion, GE’s International Maritime Organisation’s Tier 3-compliant diesel engine, a complete propulsion shaft line and propeller, a tunnel thruster, SeaStream dynamic positioning (DP) and vessel automation system.

The diesel engine reduces key emissions up to 70 percent and provides a less complex solution compared to urea-based selective catalytic reduction (SCR) systems, as it does not require any additional on-board SCR

equipment or storage provisions for urea or dockside support infrastructure for urea storage and processing.

GE’s SeaStream DP system, in the ‘energy-efficiency’ mode, is designed to generate fuel savings up to ten percent or more, with an associated nitrous oxide reduction up to 20 percent, depending on environmental factors and the operational profile.

The Chilean Navy’s vessel has received Lloyd’s Register PC 5 polar class notation. With an installed power of 14.5 megawatts, it will be capable of breaking one meter of ice at three knots.
