SKEYE IS SPECIALIZED IN SURVEYING AND MAPPING TERRAINS AND OBJECTS IN AN EXTREMELY FAST AND COST EFFICIENT MANNER. THIS IS DONE BY COMBINING LOW ALTITUDE AERIAL PHOTOGRAPHY WITH GEOMETRICALLY CALIBRATED CAMERAS USING A TECHNIQUE CALLED PHOTOGRAMMETRY.
Using this technique Skeye is able to extract X and Y coordinates together with related heights (Z) of the terrains from the objects being surveyed. This data set is used to create a 3D digital terrain model. This model allows our clients to perform fast and efficient calculations adding value to their specific business. The monitoring of stockpiles is an example of volume calculations that, performed over a period of time, gives insight in to volume and the net value changes of commodities. Flying at low altitude increases the resolution and quality in comparison to more traditional techniques. The measurement density (point density) can be as high as 100 points per square meter revealing every important detail in the terrain.
The imagery is then corrected for terrain heights and colour differences due to changing sun conditions. Further more all the imagery can be stitched into one seamless orthophoto mosaic that can be directly imported into any CAD or GIS system and that can be used to map or measure. In combination with our sister company Deep BV from Amsterdam, Skeye can even generate terrain models that extend under water.
PROJECT DUTCH OIL COMPANY Skeye secured a contract from the Dutch Oil Company NAM for the mapping and imaging of over one hundred gas exploration installations in the Netherlands. This contract is the result of a framework agreement between Skeye and NAM. The NAM selected Skeye due to its successful track record in using remotely piloted aircraft in a safe and professional manner. The NAM’s core mission is to locate and retrieve gas and oil in a sustainable manner in the Netherlands. For this purpose the NAM constantly develops and implements new techniques in order to work more efficiently in an environmentally friendly manner. The use of remotely piloted aircraft fits perfectly within this mission, as the use of remotely piloted aircraft is not only more cost effective and safe but also has less impact on the environment in comparison to the use of manned aircraft.

SKEYE IS CAPABLE TO REMOTELY INSPECT INSTALLATIONS AND OBJECTS THAT ARE DANGEROUS, DIFFICULT OR ‘LIVE’ AND THEREFORE EXPENSIVE OR IMPOSSIBLE TO BE APPROACHED BY MANNED INSPECTION TEAMS.
With different size remotely piloted aircraft Skeye can inspect indoor, onshore and offshore installations and objects in many different environments. It offers a very cost effective and quick alternative for the traditional manned inspections such as crane or rope access which are dangerous, time consuming and costly. With the remotely piloted aircraft as platform, a range of remote sensors can be positioned close to the installation or object. Skeye uses up to 36 MP cameras to capture stunning high resolution data enabling the visualisation and detection of the smallest suspected details without the need for shutting down the installation being inspected.
Our inspection services are performed as regular, emergency or pre-maintenance inspections in for instance the on- and offshore wind and oil & gas industry. Also in many other industries we inspect installations, buildings, chimneys, telecoms or high voltage pylons. Within the different industries Skeye has partnerships with specialised inspections companies in order to deliver professional and official inspection reports. This way a valuable insight in the asset’s condition and integrity is provided, enabling our clients to make calculated operational and maintenance decisions without or limiting the turn around or shutdown period. The inspections are executed in a quick, safe and cost effective manner.
PROJECT LIVE FLARE INSPECTION Skeye conducted pre maintenance, live flare inspections in order to determine the overall integrity and areas in need of maintenance. This could be planned and executed during an upcoming turn around stop. The inspection focused on the supporting structure, piping, pilot ignition, flare-tip and steam lines and included a general HD video, full coverage with very detailed high resolution photo’s and an infra red inspection on insulation and heat leaks. The final inspection report was drafted in collaboration with our project partner Lloyd’s Register, who drafted the final inspection report. All collected data made it possible for Skeye and Lloyd’s Register enabled our client to plan and execute the maintenance shut down more efficiently.
UR INSPECTION SERVICES O ARE PERFORMED AS REGULAR, EMERGENCY OR PRE-MAINTENANCE INSPECTIONS IN FOR INSTANCE THE ON- AND OFFSHORE WIND AND OIL & GAS INDUSTRY. ALSO IN MANY OTHER INDUSTRIES WE INSPECT INSTALLATIONS, BUILDINGS, CHIMNEYS, TELECOMS OR HIGH VOLTAGE PYLONS.

SKEYE HAS MANY YEARS OF EXPERIENCE IN OPERATING REMOTELY PILOTED MULTI COPTERS IN MANY DIFFERENT ENVIRONMENTS AND SITUATIONS. THE NEW AND UNIQUE PERSPECTIVE OF OUR IMAGES GIVES OUR CLIENTS THE ABILITY TO PRODUCE PROFESSIONAL PHOTOS AND VIDEO FOOTAGE FROM THE AIR.
Skeye uses a variety of remotely piloted multi copters to collect the aerial video footage. For each project we determine which multi copter is most suited to the task. Options are a GH4 4K or we will use an optically stabilised Sony CX730 HD camera in combination with a brushless gimbal. The brushless camera gimbal keeps the camera levelled at all times and is used to create professional quality smooth shots that are free of vibrations. Other options are to use a Go-Pro, a Sony NEX-7 or the Canon 5D mk2. These cameras vary between 24 and 36 MP resolution, resulting in stunningly detailed photos. In most cases Skeye will collaborate with professional production companies to
deliver a full package that would typically include extra footage from the ground, editing, voice-over and music. Another impressive product delivered by Skeye is the virtual 360-degree aerial tour. 360-degree imagery taken from a remotely piloted multicopter can, together with imagery from the ground, be combined into an aerial tour. These panoramic tours are an excellent way to provide clear visual information to your online visitors of e.g. your work site, golf course, campsite, wild life park, marina or recreational area. Important additional information can be made visible in the imagery and can be accessed by the visitors.
PROJECT GOOD ENERGY Good Energy commissioned Skeye to capture stunning images for their new wind turbine field project based at Hampole, Doncaster. Both on the ground and in the air Skeye produced time-lapse, aerial photographs and video of the installation of their new wind turbines. The site has a total of 4 turbines and is expected to generate 20,000MWh a year having the capacity to power 4000-5000 homes. The project was produced with a minimal carbon footprint by sourcing local wind turbines and contractors. The project was completed on time with careful planning between all companies involved.
I N MOST CASES SKEYE WILL COLLABORATE WITH PROFESSIONAL PRODUCTION COMPANIES TO DELIVER A FULL PACKAGE THAT WOULD TYPICALLY INCLUDE EXTRA FOOTAGE FROM THE GROUND, EDITING, VOICE-OVER AND MUSIC.

PROJECTS
ANGOLA SKEYE HAS CONDUCTED A NUMBER OF AERIAL SURVEYS FOR THE ANGOLAN GOVERNMENT IN AND AROUND THE CAPITAL CITY OF LUANDA.
PLYMOUTH BREAKWATER SKEYE WAS ASKED TO PERFORM AN AERIAL SURVEY OF THE BREAKWATER THAT LIES AT THE ENTRANCE OF PLYMOUTH HARBOUR.
One of these projects was the mapping of a 15 kilometre coastal strip in Luanda.
Skeye carried out this aerial survey in close cooperation with its sister company Deep from Amsterdam that was responsible for measuring the breakwater below the water level. Skeye mobilised on a carefully planned date so as to catch a rare window of good weather in combination with a spring tide. This spring tide was required so as to give Skeye the opportunity to collect as much data as possible from then air at low tide whereas Deep could collect as much data as possible at high tide.
Over 130 accurate ground control points were established in the area prior to starting the aerial survey. A GPS base station was setup on top of a hotel to be able to broadcast GPS correction signals in real time. With the Bird-Eye fixed wing remotely piloted aircraft over 12,000 images were taken at a height of 400 feet above ground level in 30 different flights. A special computer was used to process all the images. The result was a digital terrain model with over 25 heights per square meter, one seamless orthophoto mosaic to scale and full mapping of all houses, structures roads, waterways, drains etc.
The breakwater is close to a mile long and around 50 meters wide. Skeye conducted five separate flights using the Falcon-Eye multi-copter at a height of 50 meters. 30 ground control points were established on the breakwater as well as over 60 additional control measurements. All control was measured using a RTK GPS. All the collected images were joined to create a 3D model of the breakwater. Heights were extracted with a point density of over 50 points per m2. Subsequently the individual images were merged to create a seamless orthophoto mosaic whereby each pixel was corrected for geometry, height and colour. Deep used a multibeam echo sounder to create an under water 3D model. The final dataset was a merged 3D model of both the under and above water measurements.
BREMANGER QUARRY AERIAL IMAGERY WAS USED TO CREATE A 3D HEIGHT MODEL OF THE ENTIRE QUARRY. FROM THIS THE HEIGHT CONTOUR LINES WERE EXTRACTED. AN ORTHOPHOTO MOSAIC WAS ALSO PRODUCED FOR THE CUSTOMER.
LIGHTHOUSE INSPECTION SKEYE INSPECTED THE OLD WALLS OF THE LARGE ‘BRANDARIS’ LIGHTHOUSE LOCATED ON THE NORTHERN DUTCH ISLAND OF TERSCHELLING.
This was created by stitching together all the individual images and correcting them for height differences in the terrain.
Recent renovation works showed that the interior of the lighthouse was severely leaking in some places. This became apparent when the contractor noticed cracks during the renovation works. The contractor wanted to know if there were any more of these cracks. There were not that many alternatives to using an remotely piloted aerial vehicle. Usually this kind of inspection is carried out using a crane, however a crane of this size could not be found on the island and bringing it from the mainland would have been a costly affair.
Skeye travelled 2000 kilometres north to survey one of Europe’s largest stone quarries. Bremanger Quarry lies about two hours North of Bergen in Norway at a latitude of 61 degrees North at a height of 500 meters above the Fjord of Svelgen. The quarry produces mainly granite for road construction and stabilising offshore pipelines. The first task was to install around fifteen ground control points that were subsequently measured using GPS. A total of six flights were conducted using the Falcon-Eye unmanned multicopter to cover the entire quarry with aerial images. The aerial imagery was used to create a 3D height model of the entire quarry. From this the height contour lines were extracted. An orthophoto mosaic was also produced for the customer. This was created by stitching together all the individual images and correcting them for height differences in the terrain. In addition Skeye was asked to produce six aerial 360-degree panoramic images and a video covering the activities of the quarry. These were made using the Eagle-Eye remotely piloted aircraft.
In the Netherlands it is normally not allowed to carry out an remotely piloted flight in a dense urban area. Special permission was however granted to Skeye on the basis that the company holds a CAA (Civil Aviation Authority) permit for aerial work and that the alternative of using a crane in this location was considered a higher safety risk. Skeye deployed the Falcon-Eye multicopter. At a distance of several meters from each wall several hundred images were taken at very high resolution. Upon completion of the flying all the images were stitched together in such a way as to preserve the geometry of the tower. The combined image could then directly be overlaid on the original CAD drawings of the lighthouse. With this collaboration of real images and CAD drawings it was possible for the contractor to detect new cracks, determine the exact location and measure the size of these cracks.
