CTV motion behaviour investigated

SPOWTT project provides fresh insight into ship motions, improving the wellbeing of technicians.
The recently completed ‘Improving the Safety and Productivity of Offshore Wind Technician Transit’ (SPOWTT) project focused on improving the health and safety of technicians by developing models for a decision-support tool, assisting the shore operator in the ‘go/no go’ decision. Both ship motion and human response modelling were performed. MARIN was tasked with investigating the motion behaviour of Crew Transfer Vessels.

fresh insight into ship motions
To tackle ship motions, we used numerical simulations, model tests and full-scale performance data from an elaborate measurement campaign carried out on different CTVs over multiple years. Numerical predictions were performed using MARIN’s PANSHIP code, which is suitable for fast and advanced hull forms, and includes the modelling of propellers/waterjets, rudders, lifting surfaces, interceptors and trim flaps.
Seakeeping tests Seakeeping and Manoeuvring Basin
To be able to better isolate and address different uncertainties, seakeeping model tests were performed in our Seakeeping and Manoeuvring Basin. MARIN’s generic CTV model design was used, which represents a 25 m catamaran of 90 tonnes displacement.
