VISUAL AND THERMAL INSPECTION OF A FPSO FLARE

Background

In August 2016, one of the main majors in Angola chose ROAV7 and its local partner to perform a visual and thermal inspection of its 3 FPSOs’ flares.
Before ROAV7’s intervention, flare inspections were performed by helicopters.
The client requested the inspection to be performed within a short period of time due to the facility maintenance shutdown.

Operation

ROAV7 mobilized « first in class » technology to deliver the highest service quality. ROAV7 used high definition radiometric thermal and digital cameras for a detailed inspection of the integrity of the structure of the flare from a safe distance of 40m from the facility as determined by the client in the JRA.
ROAV7 performed the operation from a tug boat in less than 4 hours. The client representative was on board to specify the areas of interest. The images from the operation reached the HQ in Luanda within the day.
A field engineer monitored in real time the temperatures recorded by the UAV (4 engines and the battery) from an auxiliary screen, in order to avoid any overheating.
The wind and the waves (4 meters) were mitigate by specific operational program.

Personnel and equipment

2*PAX (Operations manager & Field engineer)
2*UAVs designed for inspection
2*High-definition thermal cameras
2*High-definition digital cameras
Total weight: 75 kg in 3 boxes transferred on site by the personnel (no additional external logistics required for the transfer of the equipment).

Achievements

Inconstant volumes of gas impact the heat transfer conducing to the erosion and anomalies in the structure of the flare.
The inspection conducted by ROAV7 confirmed the degradation of the platform and the client updated accordingly its mainte- nance procedures before the shutdown.

ROAV7 Mission

ROAV7 is committed to do more with less while supporting the new challenges of the Oil & Gas industry. ROAV7 actively works on data acquisition, processing and interpretation to deliver customized risk management solutions.
