A Digitised Exploration into the Design Space of Naval Power Plants: Optimal Power Plant Selection based on Ship and Client

The design space of power plants of naval surface vessels is ever expanding. As a result, the design space has become too large for a human design team to fully explore. Therefore, a concept exploration tool is introduced to generate and evaluate all possible concepts within the design space. An optimal solution is chosen based on ship...

Effective Naval Power Plant Design Space Exploration

In this paper a Concept Exploration Tool (CET) for naval ship power plants is presented. The ideas behind the CET are introduced as well as the inner workings of the tool. Objective functions for different relevant design criteria (energy efficiency, emissions, signatures, etc.) are shortly discussed, after which the results for a Frigate case...

Improving the breakwater design process by using a design automation tool

In the current breakwater design process, not all feasible concepts can be explored due to time constraints. However, designers are also influenced by breakwaters constructed near, or at the same location as their breakwater project. But also conservative assumptions influence the breakwater design process, for instance, regarding the wave...

Exploring market uncertainty in early ship design: Simulating the effect of design parameters on vessel performance in an uncertain market

To decrease Europe’s harmful emissions, the European Union aims to substantially increase its offshore wind energy capacity. To further develop offshore wind energy, investment in ever-larger construction vessels is necessary. Designing these vessels is difficult however, as this market is characterised by a large but seemingly unpredictable...

Traceability in ship design: Connecting need, requirements and design in one information model

Traceability in complex ship design involves keeping track of the evolving relations between need, requirements and design. Such traceability is not fully developed in the current design process at DMO due to divisions in the design process and between design tools. This thesis proposes to use a single information model to facilitate...

Hull Generation for Fast Concept Exploration: Development of a Brute-Force Approach to Quickly Obtain Hull Shapes and a Resistance Prediction for Offshore Patrol Vessels

Damen Shipyards Gorinchem has found deficiencies in the process of developing concept designs of Offshore Patrol Vessels (OPVs). There is a need to increase the efficiency of this process, meaning that (1) the speed has to be increased, (2) the accuracy of designs has to be increased and (3) the risk of deviations of the project plan has to be...

Applying parametric optimisation in the concept exploration phase on naval support vessels

Five naval support vessels are being replaced. For this replacement two focus points are important. The first one concerns creating more unity within the fleet, achieved by using the hull geometry as a monolithic part. The second one concerns the aim to reduce harmful emissions by reducing the effects of the energy transition by minimising the...

Integration of aboard logistic processes in the design of logistic driven ships during concept exploration: Applied to a Landing Platform Dock design case

The Defence Materiel Organisation found that using a design margin to estimate required space for logistic systems (e.g. staircases, hallways) during the concept exploration design phase is insufficient and impractical. A more educated estimation of required space for logistic systems is hard, because the configuration of systems is varied...

Zero-emission double ended ferries: A concept exploration study

The goal of this thesis has been to develop a concept exploration tool for zero-emission double ended ferries, that determines the feasibility of different energy systems, creates corresponding design parameters and helps decide between zero-emission energy types. <br/><br/>The research goal was achieved in three steps. Firstly, knowledge was...

Automatic Selection of an Optimal Power Plant Configuration: Using Client Preferences and time based Operational Profiles

Vessels are becoming more and more optimized towards their mission and an increasing amount of systems are considered during this optimization. Most of these considerations occur at an early design stage, where data is scarce and their impact is large. <br/>This research aims to aid designers in considering this growing forest of possible system...

Elucidating families of ship designs using clustering algorithms

The past decade the packing approach was developed at the TU Delft. This tool automatically generates tens of thousands of ship designs in order to fully explore the design space. This is opposed to the traditional way of ship design, where just a limited number of designs can be elaborated. The result is a set of ship designs that can be used...

Interactive evolutionary concept exploration in preliminary ship design

Preliminary ship design (or early stage design in US terminology) is the very first step in designing a new ship. In this stage ship designers attempt to find an affordable balance of the future owner's (customer or operator) ambitions and operational needs. This balance is then translated into more tangible design requirements. However, the...
