STX Canada Marine Design Proposal

The navy has released a PowerPoint slide presentation given by Mr. Dan McGreer, Principal Engineer for STX Canada Marine Inc., which provides one assessment of how a naval patrol vessel for operations in northern waters (AOPS) might look, given a number of design requirements. The presentation was given on an “AOPS Industry Day,” held on 13 November 2008.

The stated proposes of the presentation included the following:

  • To confirm the feasibility of the AOPS requirements;
  • To determine any ‘design drivers’; and
  • To present one possible design solution form many possibilities.

The design considerations resulted in a ship with the following basic characteristics:

  • Length (over-all): 109.6 metres
  • Breadth (over-all): 18.2 meters
  • Displacement: 6940 tons
  • Open Waters Speed: 20 knots
  • Crew of 45 plus accommodations for 40 supernumeraries
  • Ship’s Stores for 120 days’ endurance

Among the presentations many interesting conclusion are the following:

  • The sea keeping requirements were found to be feasible with limited slamming, wetness, and motion induced interruptions, no propeller emergence, and no operational restrictions; and
  • The Definition Design can be equipped with aviation facilities to support landing, stowing, refueling, and minor maintenance of one Bell 212 or 412, or Sikorsky CH148 ‘Cyclone’ helicopters.
