Abstract
Free-Fail Lifeboat (FFL) has become a common lifesaving appliance on ships
and offshore facilities. However, the manner of launching a FFL may cause
potential danger of an injury to its occupants. Therefore prediction of the
launching kinematics of FFL is of paramount importance for the design process.
The paper is focused on experimental assessment of the launching trajectory
and accelerations of FFL. The experiment results were used to determine certain
data necessary for the computation and as a reference data to verify the results of
computer simulation. Tests were carried out on scale models and prototype of a
FFL. Some results of the simulation and experiments are indicated, as well as
conclusions regarding use of the proposed method to support the process of
designing free-fall systems.
