Abstract
Development of an aerial robotic oil spill surveillance (AROSS) system for constant surveillance and detection of spills from crude oil pipelines. International Journal of Unmanned Systems Engineering. 4(2): 19-33. Current crude oil spill detection methods can only be employed intermittently and do not detect spills at their onset. The Aerial Robotic Oil Spill Surveillance (AROSS) System is a novel system that addresses this limitation. A single AROSS system is a 550 mm x 550 mm quadcopter weighing 1.5 kg. Autonomous navigation of the system is achieved using a GY521 gyrometer, BM085 Altimeter, HC-SRO4 ultrasound sensor, and Global Positioning System (GPS) module. Spills emanating from crude oil pipelines are detected using MQ gas sensors. An LS-Y201-Infrared camera is used to capture images of the spill site. Xbee Pro 900HP modules establish wireless connection between the system and the base station up to 45 km away for transmitting spill data to surveillance teams. The AROSS system was tested on a 100 m section of an underground crude oil pipeline in Effurun, Nigeria. The threshold voltage for spill detection by the gas sensor was determined experimentally to be 2.93 V. The system successfully detected 1 liter crude, which corresponded to an output voltage of 2.95 V. Spill GPS location and images were remotely transmitted to a manned base station 100 m away from the pipeline. The AROSS system has the ability to provide autonomous and constant surveillance for crude oil pipelines, detect spills as soon as they occur, and inform the appropriate authorities.
