Emprego de aeronave remotamente pilotada (arp) para medição de offset

Abstract

This work addresses the importance of accurately measuring equipment offsets on vessels, considering the relevance of this parameter for the safety and efficiency of maritime operations. The conventional method of offset measurement, which involves traditional topographic techniques, is accurate but time consuming and requires the vessel to be in dry dock, resulting in costly periods of inactivity. The study proposes the use of Unmanned Aerial Systems (UAS) to perform offset measurements with the ship docked, aiming to reduce docking time and associated costs. The use of drones offers advantages in terms of accessibility, cost, and eliminates the need for dry docking. The research includes an analysis of the accuracy of measurements taken with UAS compared to the conventional method. The results show that measurements taken with UAS are precise, with minimal differences compared to conventional measurements. However, there are challenges related to defining the center of the Vessel Coordinate System (VCS) and visualizing equipment below the waterline. In conclusion, the use of drones is a viable alternative for offset measurements, especially in situations where dry docking is not possible. However, it is important to consider the need for clear reference points and precise definition of the VCS.
