ABSTRACT
Ship design is a complex endeavor requiring the successful coordination of many disciplines, of both technical and non technicalnature, and of individual experts to arrive at valuable design solutions. Inherently coupled with the design process is design
optimization, namely the selection of the best solution out of many feasible ones on the basis of a criterion, or rather a set of criteria.
Such evaluation criteria are the shipbuilding cost or the required freight rate for merchant ships or more complex ones that include
besides economy, ship’s performance in terms of safety, comfort, survivability in intact and damage condition and environmental
friendliness. A systemic approach to ship design may consider the ship as a complex system integrating a variety of subsystems andtheir components, e.g. for merchant ships subsystems for cargo storage and handling, energy/power generation and ship propulsion,accommodation of crew/passengers and ship navigation.
Also, considering that ship design should actually address the whole ship’s life cycle, it may be split into various stages that are
traditionally composed of the concept/preliminary design, the contractual and detailed design, the ship construction/fabrication
process, and ship operation for an economic life and scrapping/recycling. It is evident that an optimal ship is the outcome of a holistic
optimization of the entire, above defined ship system over her whole life cycle. But even the simplest component of the above
defined optimization problem, namely the 1st loop (conceptual/preliminary design), is complex enough to be simplified (reduced) inpractice. Inherent to ship design optimization are the conflicting requirements resulting from the design constraints and optimization
criteria (merit or objective functions), reflecting the competing interests of the various ship design stake holders (ship-owner,shipbuilder, cargo owner and cargo forwarder, flag and class authorities etc.).
The presentation provides a brief introduction to a holistic approach to ship design optimization, defines the generic ship design
optimization problem and demonstrates its solution by use of advanced optimization techniques for the computer-aided generation,
exploration and selection of optimal designs. It discusses proposed methods on the basis of some typical ship design optimization
problems of tanker and passenger ships related to multiple objectives and leading to improved and partly innovative designs withincreased cargo carrying capacity, enhanced safety, survivability and comfort, reduced required powering and improved
environmental protection.
