Fakel Burner Inspection

(Inspektion einer Abfackeleinheit) - Quelle: Workswell-Testbericht

CONDOR Solutions carried out new inspection of the fakel burner in the facility of Lunskoe OPF in October 2016. The facility is owned by Sakhalin Energy whose major shareholders are the companies Shell and Gazprom. The facility of OPF is located in the Northeast coast of Sachalin island in the Russian territory. It is located 7 km in the inland region, at the place of influx of the gas-pipeline from the platform Lunskoe A. The entire facility takes the area of more than 62,000 m2.

Fakel Burner

The primary function of OPF is aimed to processing of gas and condensate from the site of Lunskoe, as well as preparing them for transport by the pipeline to the export crude oil terminal and production plant of compressed gas LNG – Prigorodnoe Complex. It also receives gas and crude oil from the platform Piltun-Astochskovo-A and the platform Piltun-Astochskovo-B, while preparing them for transport to the export terminal in the south of the island. There are pumps which allow processing up to 195,000 barrels a day. At full capacity, this facility can handle 51 million m3 of gas/ day and 9,500 m3 of condensate or crude oil / day. All technological systems at the OPF were commissioned in 2008.

An important part of the facility is also a system of burners, e.g. the burners (Flare System) of low and high pressure. They were also subject to inspection carried out by the company CONDOR Solutions. The weather during inspection was cloudy, with the wind of 14 m/sec and the temperature of -10°C.

Why inspection is important

The primary task was to conduct visual inspection using a UAV technology. However, in addition to the standard camera SONY Alpha 7R, we were newly using the thermal camera of Workswell, e.g. the thermal imaging camera Workswell WIRIS.

The operational technologies are exposed to extreme weather conditions due to the geographical location. Mast of the burners is exposed to very low and freezing temperatures (-) and also to extreme positive temperatures (+) caused by gas combustion. Therefore, it is important to check out the system of burners completely, using thermal imaging camera.

Inspection with Workswell WIRIS

Thermal imaging camera Workswell WIRIS allowed us to measure the temperature of the entire system of the burner. Doing the measurements, we have found that the burner system includes both low and very high temperatures. Therefore, we divided the measurements into two parts, as follows: – burner’s mast from the bottom part up to the top service runway. – upper part of the burner’s shank. This thermal imaging camera offers possibility of measuring the temperatures up to 1,500°C, using a high temperature filter, as the only one of the systems available for the drones.


In the first part, we found out the temperature of the mast and the rising pipeline of the system of high and low pressure; we also prepared the temperature profile, as shown in the figure. The graph and thermogram clearly show where the pipeline isolation finishes. At this point, the temperature sharply increases up; and consequently the temperature gradually decreases together with the height, up to the upper part – the shank; then the temperature rapidly increases up again. Up to the temperature of about 2,000°C.

Based on information obtained by the thermal imaging camera of Workswell WIRIS and the unmanned aerial vehicle, the company CONDOR Solutions compiled the final report which described in detail the condition of the burner system of high and low pressure. The operator, e.g. Sakhalin Energy, has got the data on the basis of which it is possible to schedule maintenance works so that restriction of the production process in the facility is minimized as much as possible.
