A Current

This paper by the Vice-President of the Netherlands Ship Model Basin presents the results of a study performed on the N.S.M.B. ship manœuvring simulator aimed at the development of criteria for the manœuvrability of ships sailing in a current. Six pilots navigated four types of 250,000 d.w.t. tankers in sixteen different conditions of current.Ships have grown so large that it is no longer taken for granted that they can be manoeuvred as required. The problem can be split up in two aspects, the ship's inherent manoeuvring ability, which is mainly a technical problem, and the mariner's ability to manœuvre the ship, which is mainly a psychological problem.

To Receive

This article is concerned with the reasons why sometimes good arguments in health communication leaflets fail to convince the targeted audience. As an illustrative example it uses the age-dependent eligibility of women in the Netherlands to receive routine breast cancer screening examinations: according to Dutch regulations women under 50 are ineligible for them. The present qualitative study rests on and complements three experimental studies on the persuasiveness of mammography information leaflets; it uses interviews to elucidate reasons why the arguments in the health communication leaflets for the exclusion of women under 50 from routine mammographic screenings do not work.

Platform Motions

This paper reviews briefly the results and problems associated with model tests in waves on moored, floating drilling platforms. It considers the analysis of the observed phenomena which is based on experience gained from several tests on these structures carried out at the Netherlands Ship Model Basin. Most parameters which affect the motions of the platform are interrelated and not independent of one another. Consequently, the effect of any given parameter is hard to distinguish and thus limits the number of design trends and behavior predictions which could be formulated. Three important tends were noted, however, and can be summarized as follows:The important platform motions with respect to drilling ease are most favorable with a deep-draft platform;the behavior in waves is relatively independent of platform displacement;the optimal section shape of the horizontal underwater structures with respect to the platform motions depends upon the expected wave periods to be encountered. The results presented are based upon a limited number of tests and must be applied only with caution. Model tests still are the only reliable method of predicting the behavior of a proposed drilling platform.

Wake Survey

In this paper the wake survey data of a family of models of the Victory ships measured and reported by the Netherlands Ship Model Basin are further analyzed. The scale effect upon the circumferential mean wake velocity and the harmonic contents of the circumferential velocity distributions are examined. It was found that for the relative amplitude of the various harmonics of the circumferential velocity distributions, the scale effect does not seem to be important. However, the effect of scale on the absolute amplitude of various harmonics could not be established. Extrapolated curves of the circumferential mean and the volumetric mean velocities for the ship are presented. Also reported are the effects of roughness, the comparative studies regarding the symmetry and repeatability of measurements, and the effect of rudder.
