USCGC Polar Sea
The following is copied directly from the CG-9 web site.
“The Coast Guard issued a request for quote (RFQ) on Dec. 22 for industry studies to identify solutions for the heavy polar icebreaker that minimize cost, schedule, production and technology risk. The request can be found here.
“The Coast Guard expects to award multiple industry study contracts early next year. This will be followed by a request for proposal for detail design and construction of heavy polar icebreakers in 2018.
“The deadline to submit responses to the industry studies RFQ is Jan. 20, 2017.
“This request is part of a larger industry engagement strategy supporting the Coast Guard’s effort to expedite the recapitalization of the heavy polar icebreaker fleet. In addition to the industry studies request, the Coast Guard has sponsored industry day events to promote communication on mission and design requirements and solicited input from industry on acquisition approach and schedule.

“The U.S. Coast Guard today awarded five firm fixed-price contracts for heavy polar icebreaker design studies and analysis.
The contracts were awarded to Bollinger Shipyards, LLC, Lockport, LA; Fincantieri Marine Group, LLC, Washington, DC; General Dynamics/National Steel and Shipbuilding Company, San Diego, CA; Huntington Ingalls, Inc., Pascagoula, MS; and VT Halter Marine, Inc., Pascagoula, MS.
The combined total value of the awards is approximately $20 million.”
That should give them plenty of design options.
Good news. Thanks. Full results expected to take 12 months.
