More information about Assistance in sea trials
What is sea trial assistance?
Sea trial assistance consists of the technical evaluation of the structural, mechanical and acoustic performance of a vessel under actual operating conditions. Its objective is to identify possible failures or necessary adjustments before final delivery.
At Preditec, we apply advanced instrumentation to analyze in real time critical parameters such as vibrations in drive shafts, structural noise, energy efficiency and mechanical stability. Our technical team evaluates these factors and offers corrective solutions to optimize vessel safety and reliability.
