Project Series A of Special Research Series 98 is a programme of studies commenced in 1972 with the aim of developing a systematic approach for a quantitative determination of the active collision safety of a ship dependent upon its physico-technical parameters and the environmental factors. The means of the collision susceptibility of a ship is taken as the collision rate, i.e. the probability of a collision occuring within a given service life. Proceeding from this basis, the collision rate has been calculated as a function of the hydrodynamics of the hull, propeller and rudder, the mechanical and electro-mechanical properties of the propulsion and manoeuvring as well as the statistically evaluated operating environment. This complex exercise has necessitated the cooperation of a number of specialists in such subjects as manoeuvring, hydrodynamics, propulsion and systems techniques. For organizational purposes the work was carried out in five subdivisions: A1--Preparation of a mathematical model for calculating the collision rate (Technical Director: Professor Krappinger). A2--Preliminary Calculation of ship motion for arbitrary evasion and stopping manoeuvres with the aid of Planar-Motion-Model tests. (Technical Director: Professor Grim). A3--Behaviour of the propeller in evasion and stopping manoeuvres (Technical Directors: Professors Grim and Isay). A4--Control and revising behaviour of main propulsion machinery (Technical Director: Professor Geisler). A5--Effect of steering gear performance and construction on the dynamic behaviour of steering gear (Technical Director: Professor Wangerin). This monograph contains the collected contributions to each of these sub-projects. Order from BSRA as No. 50,019.
