Pires da Silva, P. Sutulo, S. and Guedes Soares, C. (2024), Setup, collection, and processing of manoeuvring full-scale sea trials data of Navy ships, Advances in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor and Francis, London, UK, pp. 343-352.
A data acquisition system used in manoeuvrability tests on naval ships is described. Data are recorded using a portable setup of sensors and also the ships’ own sensors. The parameters recorded are: the ship’s instantaneous geographic coordinates; the speed relative to the ground; the heading; the heading, yaw and roll angles, the corresponding speeds and accelerations; forward and drift accelerations; the wind, the speed relative to the water, the instantaneous propellers‘pitch, the shafts’ rpm, power and torque. Sea trials are carried out in waves and calm seas. Given the lack of an own ship data fusion network, the data fusion is produced digitally in post-processing through data selection, data synchronization and data filtering algorithms. This work discusses the challenges associated with the organization and execution of the full-scale sea trials, the data post processing and the results obtained, namely the kinematics for the turning, zigzag and spiral manoeuvres.
