Richard Sauter Draws Up a Hybrid Coast Guard Vessel

The low-emission design specialists at Sauter are at it again, having been hard at work designing this – a low-emission military catamaran they’ve pitched to the USCG E Class Sea Eagle, which Sauter calls “The Ultra Green Homeland Security vessel that’s tough on the bad guys, but kind to the Ecology.”

We’ve covered Sauter’s designs before – sometimes taking the company’s claims at face value, and sometimes with a bit more critical thinking snark than Sauter probably deserved for trying to “fight the good fight” and wrangle a little PR along the way.

SO, the guy’s still at it. Good on him!

You can get an idea of the proposed Sea Eagle’s size and scale in the drawings, below. They do a good job of the 43M hybrid-driven vessel that (according to Sauter) will be good for 32 Knots in open water, thanks to the 5000 hp on-tap and Sauter’s low-weight/low-drag catamaran design.

I’ve included Sauter’s own summary here, and (since he’s always chimed in before) invite you to ask Sauter any questions you might have for him in the comments, below.

SCOD Presents the US Coast Guard Sea Eagle; The Ultra Green Homeland Security vessel that’s tough on the bad guys, but kind to the Ecology. The first Coast Guard Cutter to provide extensive surveillance, on , above and below the ocean.

The E Class Search and Rescue Sea Eagle with Helipad and underwater ROV (Remote Ocean Vehicle) uses half as much fuel to go 10% faster than the USCG Sentinel Class Fast Response Cutters’ in use today. At the Same time The Sea Eagles waterjet propulsion system, dynamic positioning and small wave making signature do far less harm to Marine Ecology.

Instead of the Sentinels 11,500hp from tier 2 diesel engines, the analogous Sea Eagle uses a total of 5,000hp from Solar Hybrid power sources that include cleaner MTU tier 4i Diesels. With less than half the fuel consumption of the Sentinel Class FRC’s, the Catamaran Sea Eagle’s greater overall efficiency delivers a maximum speed of 32 as opposed to 29 knots.

In silent electric mode the SEA Eagle will navigate inland water ways and dock with Zero emissions. Plugged in her solar cells can harness and return over 200 MWs of energy to the grid a year, enough power to offset 3000NM of Carbon Neutral cruising at 18 knots. As a Certified Carbon Offset Project the E Class Coast Guard Cutter can reduce GHG emissions by 12,000 tons per year
Energy from the grid or captured from her 100KW solar array is stored in a Lloyds approved Corvus 2MW Lithium UPS. The 16ton weight of the batteries also serves as the Mass in the MDR (Motion Damping Regeneration) system that acting like a TMD (Tuned Mass Damper) in a skyscraper will generate electricity as it dampens the motion of the vessel.

Combining the MDR with the self leveling T-Foils in each hull greatly improves the ride, related safety aspects and the accuracy of the stabilized remotely operated 25 mm chain gun, and the four crew operated .50 caliber machine guns.

The Coast Guard Sea Eagle FRC will accommodate 30 crew members and like all USCG Fast Response Cutter’s her command, control, communications, intelligence, surveillance and reconnaissance (C4ISR) system will be fully interoperable with those of the Department of Defense and the Department of Homeland Security.

“Government Agencies like the Department of Defense and the Department of Homeland Security while protecting us can also play a major roll in protecting our way of life for future generations. They have the opportunity, if not a duty to do this by insuring that only the best examples of fuel efficient Eco Conscious Vessels are to be found in our Coast Guard and Navy … the E Class Sea Eagle is such a vessel”
