Feasibility Design

The Gibbs & Cox Feasibility Design services process is an expansion of the efforts conducted in the conceptual design phase and includes further trade-offs, in most cases of the system/subsystem level, oriented toward whole ship optimization. Systems engineering plays an important part in this optimization process since it is through systems engineering that requirements at the total ship level are allocated to the system/subsystem level and to the component level. Emphasis is generally placed on performance characteristics including combat capability, speed, endurance, sea keeping,
survivability in hostile environments, noise, vibration, etc.

These studies evaluate impacts to general arrangements, equipment space arrangements, weights, trim and stability, longitudinal strength, speed and endurance, structure, electric load analysis to size main generators and sizing of major auxiliary equipment (AC plants, distillers, etc.), cooling loads, auxiliary systems and any other element of the ship design The studies involve trade-offs of system/subsystem alternatives to define total ship impacts as well as special studies to evaluate new concepts, and develop lessons-learned input to the design and design review.

Examples of Gibbs & Cox studies include the following advanced ship types:

  • 5000 Ton Advanced Naval Frigate
  • PFG2 for ROCN
  • Frigate for Greek Navy
  • Frigate for Spanish Navy
  • FFX (Monohull and SWATH), guided missile frigate
  • CGV, missile/VSTOL aircraft carrying cruiser
  • ASW Destroyer
  • Shallow water ASW ship
  • T-AGX common hull SWATH
  • PXM combatant (hydrofoil, SES, monohull)
  • NATO Corvette
  • Advanced DDG destroyer (SWATH, monohull, SES)
  • LPX amphibious assault ship
  • LPS landing support ship
  • Sealift ships (SES)
  • CGBL (Cruiser Baseline)
  • Focus Mission Ship
