W E S T EUROPEAN CONFERENCE ON MARINE TECHNOLOGY
ADDRESS OF WELCOME
Professor J. D . VAN MANEN: On behalf of the Executive Committee I welcome you very heartily to our first West European Conference on Marine Technology. This meeting, to be held in The Hague and Delft, has been imtiated by the British, French, German and Dutch Institutions of Naval Architects and Marine Engineers.
SuniJar organisations in Finland, Norway, Sweden and Spain have reacted positively to secure further co-operation.
The Executive Committee hopes that the conference will demonstrate in a clear way the extent of co-operative relationships between European institutions of marine technology and as such assist in improving the image of European shipbuilding. Especially in these days it is hoped that co-operation within the European context may help to resolve some of the rather artificial barriers between marine technical disciplines that still exist, largely as a result of an outmoded tradition rather than logic.
There is a real need for the West European Conference bn Marine Technology to succeed.
During the preparations for this Conference the Executive Committee have already had many interesting meetings in coming to satisfactory conclusions, for example, as to the selection of papers.
Personally, I appreciate very much the attitude of our German friends, who have combined their summer meeting with this first West European Conference on Marine Technology. The result is that 40 per cent of the participants are from Germany.
I should now like to invite His Excellency, Minister Trip, Minister of Science Policy, to open the Conference.
OPENIVG OF THE CONFERENCE
His Excellency F. H . P. TRIP, Minister of Science Policy: I t is a pleasure for me to open your Conference. I regard it as a great privilege that our country has been elected as the host country for your first Conference. In this circle I do not have to emphasise that Holland is a seaminded country. Our history speaks for itself. Our geographical location in the delta of great rivers made us a seagoing nation, so we should, i f only froni tradition, be interested in the theme of your Conference. Nevertheless, it was not traditional feelings that inspired me to accept very gladly your invitation to open this Conference. On the contrary, what drew my attention to your Conference were your excursions into the far future of ship and harbour design, with all the implications for our society as a whole. It is particulady appropriate to note the wide scope of the Conference theme, which includes the integration of ship and harbour design and the handling of large ships.
The subjects you will be discussing are matters of direct concern for the governments of countries with large coastal and harbour areas. Sea transport plays a very important role in the societies of the West European countries participating in this Conference.
One facet of this role that concerns me in particular is the influence that sea transport in all its consequences and multi-disciplinary character is bound to have on the national and international programmes for research and development.
If I understand the trend of your studies coirectly, it seems that your analyses of the future of West European marine technology are leading to the conviction that in order to build up a competitive industrial quality you will more and more have to resort to a scientific approach. From the experience in my own office 1 know that the wish to keep up with other countries is a significant criterion when it comes to the distribution of funds for research and development. Although the wish to keep up with the Jones' can certainly stimulate valuable new activities, it should not, as I see it, be the only directive for charting your course to the future. The magnetic compass is no longer sufficient in modem navigation; likewise one also needs other tools in research for evaluating which way shippmg, and thereby shipbuilding and harbour design, will go. The position for tomorrow's society will to a great extent be determined by the research and development of today.
The mechanisms of our society have become so complex and dynamic that we need the help of scientific methods not only for setting the course by way of long-term planning but also for pursuing this course—for the location and identification of the obstacles, and even for finding escape routes around these obstacles.
World shipping, especially bulk transport, is increasing at a rate of 8 to 10 per cent per annum. This growth rate is in itself indicative of the increased trade between nations. Traditionally this international trade has very largely been based on an exchange of raw materials from underdeveloped countries against the industrial products ofthe developed nations. The energy crisis of last year gave us a warning that this traditional balance of trade might no longer govern world trade in the same way as it has in the past. The trade patterns for food, oil and ore have a direct impact on shipping, with the evolution of the type of shipping determining the change in port conditions. Just as you have done in the past, the shipbuilding industry will adapt itself to the building of the new types of vessel. The dramatic changes in the size and function of ships create problems for shipyards and docks. They also confront public authorities with difficult matters of long-range planning which need urgent attention, such as the problems of dredging the channels, enlarging the ports, as well as the social impact of the changes in dock labour force related to the creation of specialised ports which follow the introduction of specialised ships. In weighing up all these developments we on the Government side must be careful to distinguish between short-term and long-term trends.
It is for this reason that I am grateful to those who took the initiative to organise this Conference which you are starting today. A Conference such as this will certainly help you to formulate your expectations and preferences in regard to the future of your profession.
In conclusion, I wish your Conference well, and hope that it will generate some new ideas which will bé evaluated later and—most important—passed on to all those persons and institutions that will benefit from them. 1
I regret immensely that I will not be able to attend the rest of this morning's meefing; my obligations in Parliament make this impossible. But I do hope in due course to read the Proceedings of your meeting and in the meantime I wish you again a most successful and inspiring Conference.
