The Innovative Acquisition of Hi-Res Base Map Imagery from Unmanned Aerial Vehicles & their Web Map Application for Shell’s Scottish Terminals
The Shell Geo-Information Team in Aberdeen had been working on a new Web Map for their Scottish Onshore Terminals but had struggled to find any quality, low cost base map imagery. In a moment of serendipity, we discovered that multi-rotor UAV’s (Unmanned Aerial Vehicles) had been deployed at the Brent Delta Platform for the purposes of Inspection & Integrity monitoring (as part of a wider Decommissioning Project). On learning that Cyberhawk, the Scottish based commercial UAV service provider, also had a Survey Division, we opportunistically “piggy backed” their Engineering Inspection Campaign for the procurement of Geo-referenced Aerial Orthophotos at the respective Mossmorran, Braefoot Bay & St. Fergus Terminal sites. The paper highlights how the imagery was acquired via a fixed wing UAV (a “first” for Shell) and then integrated with other data sets as we sought to deliver a general purpose/emergency response style Integrated Web Map. At the time of writing, the scope of the project has now matured to include “Google Streetview” style 360° imagery & more multi-rotor Oblique Photos which can be leveraged for both Engineering & Situational Awareness purposes. This paper shall be co-authored & presented with Cyberhawk who will summarise their own learning’s with regards to constraints, acquisition / processing workflows & image optimization.
David Edem, Tullow Oil
Tullow Oil is committed to planning and monitoring its East African onshore operations especially around well sites and camps, which includes well pad restoration, planning facilities locations, new roads, as well as species monitoring. These assignments require ultra-high resolution (<10cm) aerial imagery taken at regular and flexible intervals and traditional aerial surveys by manned aircraft / satellite imagery are expensive and often lack the required resolution.
The Tullow GIS team has adopted UAV technology to solve this challenge. Lightweight hand launched fixed winged UAVs are being used in East Africa to acquire aerial imagery at 5cm resolution with same day image processing and delivery. The UAVs are quiet, battery operated, with a flight endurance of up to 45 minutes, are easy to use and can be rapidly deployed.
This paper will share Tullow’s experiences of UAV implementation since 2011, including obtaining governmental permissions, operational challenges and existing/potential applications of UAV technology.
