Designers & Planners Completes Replacement Study On Alaska Ferry

Designers & Planners, Inc.

(D&P) of Arlington, Va., one of three firms awarded a replacement study contract by the State of Alaska, recently delivered its conceptual design study for the replacement of the aging Tustumena. This work represents an expansion of D&P involvement in ferryboat work for the State of Alaska. Prior to this conceptual design study, D&P had provided the production drawings for the 408-foot passenger / c a r ferry Matanuska.

The recent replacement study, directed by Carlos Tomassoni, director of ship design and marine economics at D&P, was completed in the required 63 days, and involved a fleet transportation analysis leading to a conceptual design of the optimum replacement vessel.

Concept designs, incorporating the results of the hydrodynamic trade-off with payloads and schedules for completing solution fleets, were prepared and costed on the basis of similar vessels built in U.S. yards. Operating costs for c o m p e t i t i ve systems were determined, and implementation schemes for future acquisitions for the fleet taken as a whole were developed for total system comparisons.
