As mainframe computers stabilised and became widely available in the late 1960’s, shipbuilders and designers progressively introduced computing for Naval Architecture, Engineering Calculation – particularly Structures, Lofting for Numerically Controlled Machines, and Materials Management. 

In 1973 the first ICCAS International conference was held in Japan  to discuss the practical application of computing systems in Shipbuilding. ICCAS conferences, initially three yearly, are now held every two years at global Shipbuilding/Marine related location. 

ICCAS is renowned for extensive international participation, high quality papers, and a preference for papers which include a practical application of the implementation of computing systems, in actual use or in trials.

Participants in ICCAS include Shipbuilders, Design Agencies, Computing System Vendors, Research Organisations, Academia, Classification Societies, Shipowners, Ship Operators, and other organisations involved in the design, build, and operation of ships.


ICCAS conferences take place over three days, each day having three tracks of presentations of submitted papers. Tracks are loosely categorised into Design, Production and Processes, and Information Technologies. Papers often discuss topics than span more than one of these catogories and are allocated to tracks as appropriate. Within each track, sessions are arranged with papers on a common theme to ensure continued interest from delegates attending the session.     

ICCAS conferences include a hosted  Dinner.  A visit to a local shipyard or marine related organisation is also arranged for all participants.

All ICCAS authors and delegates receive published proceedings, and a USB memory stick or CD containing papers and presentations that have author approval for distribution.

Scope of Papers

In the early days of ICCAS, submitted papers addressed how computing systems were being successfully applied globally in shipbuilding. A forum for shipbuilders to understand the benefits of successful use of computing across the industry, and share common problems and concerns with peers when investing in information technology.

Computing technologies are extensively applied across all functions of a typical shipyard and operation of a ship. ICCAS participants now discuss optimising installed systems to improve productivity and performance, exploiting to maximum advantage the high volumes of data created, and understanding advancements in computing technologies.

Information/data exchange and interfaces between shipbuilders, design organisations, suppliers and ship operators are increasing significantly as technology becomes very powerful, internet capable, and cost effective.

Papers submitted to ICCAS address all the above topics, give an indication of progressive trends on use of computing in the industry, and present a vision of the future use of developing technologies.

Event Management

The Royal Institution of Naval Architects (RINA) manage ICCAS conference events on behalf of the ICCAS chairman. 

RINA manage the submission of abstracts, papers and presentations, the registration of all conference authors and delegates, and the setting of  the conference date and the setting and management of deadline dates for author submissions and deligate registration. 

RINA, in conjunction with ICCAS, manage the international conference marketing, the publication of the Call for Papers, and instruction for authors on form and content of papers. 

RINA select the venue, arrange the presentation equipment and media, organise the conference dinner, arrange the shipyard visit, and publish and distribute the proceedings.

RINA arrange sponsorship and exhibitor opportunities at the conference
