Development and experimental testing of a collaborative design rationale method for early-stage ship layout design

Design rationale is a promising way of capturing design decisions and considerations for later retrieval and traceability to improve collaborative design decision-making. To achieve these perceived benefits for early-stage complex ship design, this paper first elaborates on the development of a proof-of-concept design rationale method. The...

Interactive Multi-Constrained System-To-Compartment Allocation To Support Real-Time Collaborative Complex Ship Layout Design Decision-Making

The development of concept designs during early warship design stages is essential to inform stakeholder dialogues on technical feasibility, affordability, and risk. One of the key aspects of warship concept designs is the layout of systems in the overall arrangement. The adoption of real-time design processes, such as concurrent design, require...

Alternative Energy Carriers in Naval Vessels

In order to reduce fossil fuel consumption of the Royal Netherlands Navy (RNLN) by 70% in 2050, the use of alternative fuels on the large naval surface vessels is examined. This paper examines the implications for the design and operational effectiveness of these vessels by performing two case studies of the Zeven Provinci¨en air defence and...

Early-stage design of novel vessels: How can we take a step forward?

The aim of this paper is to discuss the challenges associated with the early-stage design of novel and reliable vessels, and discuss some of the expected benefits of the application of multi-fidelity models in addressing some of their early-stage design problems. Traditionally, early-stage design tools are computationally cheap, but lack in...

WARGEAR: ‘Real time’ generation of detailed layout plans of surface warships during early stage design

Generating detailed warship layouts is crucial to check technical feasibility and performance consistent with emergent requirement elucidation during early stage design. However, generating feasible detailed layouts is a complex and time consuming task. Even today, detailed layout plans are often manually drawn using CAD software, taking up...

Assessing complex failure scenarios of on-board distributed systems using a Markov chain

Vulnerability reduction is an important topic during the design of naval ships because they are designed to operate in hostile environments and because their on-board distributed systems are becoming increasingly complex. The vulnerability needs to be addressed in the early design stages already, in order to prevent expensive or time...

A Markov-based vulnerability assessment for the design of on-board distributed systems in the concept phase

Naval ships are designed to operate in a hostile environment. As such, vulnerability is an important aspect that needs to be assessed during the design. With the increased interest in electrification and automation on board naval ships, the vulnerability of distributed systems has become a major topic of interest. However, assessing this is...

Design and control of hybrid power and propulsion systems for smart ships: A review of developments

The recent trend to design more efficient and versatile ships has increased the variety in hybrid propulsion and power supply architectures. In order to improve performance with these architectures, intelligent control strategies are required, while mostly conventional control strategies are applied currently. First, this paper classifies...

Quantitative assessment of material composition of end-of-life ships using onboard documentation

Ship recycling yards around the world offer a price to the ship owners for buying an obsolete vessel to demolish and recycle based on the ship's end-of-life weight. The offer price is mainly based on the type of ship and the estimated quantity of steel available. The steel weight estimation, in terms of percentage of lightweight (LDT), is...

Towards a different view on ship design: The development of ships observed through a social?technological perspective

The research this paper reports on aims to develop a design and engineering strategy for complex ships in between incremental and radical innovation. The majority of European ship-design industry concentrates on the development of complex, one-off ‘specials’ for the offshore industry, like dredgers, drill ships, pipelaying ships, et cetera. This...

Improved models in the design of complex specials: Success or failure?

The European Maritime cluster remains a very important player in the design, production and operation of Complex Specials, but under pressure of competitors in the Far East both the design and the design approach has to 5e improved to maintain its maricet position. The problem of any new method is that it should comply with boundary conditions...
