close visual inspeCtion

The use of Aerial Drones has now become a massive innovation in Inspection allowing visual analysis of areas usually off-limits due to inaccessibility. PFL Engineering Services Ltd. is introducing Remotely Operated Aerial Vehicle (ROAV) inspection techniques to provide structural inspections of high or difficult to reach structures which are faster and safer than conventional access methods. Structures include drilling derricks, elevated pipe racks, platform legs, splash zones, ducting and walkways. Our inspection technique reduces costs by removing the requirement for large areas of scaffolding and improves safety by reducing the need for working at height and over side work.

PFL Engineering Services Ltd. has the experienced and highly trained pilots required to fly under the deck of an offshore production platform or drilling rig to conduct close visual inspection of this hard to reach area. Our ROAV technology can look vertically up and zoom on areas of interest. Our structural engineers then write a detailed report on the condition of the structure. This avoids the need for large scaffolding or rope access work scopes. Over side work and stand by vessels are similarly not required.

Using Cyber Hawk ROAV technology (http://www.thecyberhawk.com) and advanced photogrametery software, PFL Engineering Services Ltd. captures a series of individual aerial images and processes them to create an accurate 3D model and highly detailed orthophoto mosaic of any offshore structure or tower in refineries or petro chemical plants. This allows the user to visually scan the full height and 360 degree platform model for any defects to be measured.

We also provide an innovative solution to inspect onshore and offshore vent stacks and exhausts while they are live. This significantly reduces costs by avoiding the need to shutdown to complete inspections. This technique also reduces the need for working at height and our gas sensor on the ROAV ensures safe operations.
