The way to inspect inaccessible areas indoor and outdoor &#; both offshore and onshore.

An increasing number of companies today are using drone technology for visual inspection, as it is a cost-conscious and effective way to inspect at heights and inaccessible areas.

The advantages of drone technology

The use of drones offers advantages such as:
  • Quick overview and evaluation of the condition
  • Sharp and detailed photographs of defects
  • Preventive maintenance planning and optimised production
  • Access to hard to reach areas
  • Reduced downtime
  • High level of safety.
At FORCE Technology we only use drones when concluding that it is the optimal solution. With our extensive experience of all kinds of inspections, we always offer the best solution, tailored for the job &#; with or without a drone.

Typically, we recommend drone inspection for the following three categories:

1. Offshore constructions

The offshore environment is often regarded as tough and demanding, where it is vital to keep faults as well as loss of production at both the installation and the inspection equipment to a minimum.

One example of an assignment containing these elements is a flare inspection on an oil-gas platform, where the flare is still active. Here the drones collect picture- or thermographic data of the flare&#;s condition, while production continues unaffected.

The data collection takes place in a turbulent and flame-filled environment, whilst the drone pilot, inspector and employees are at a safe distance from the inspection area and therefore out of the risk zone.

2. Onshore constructions

Normally drones are restricted to flying at an altitude of 100 meters. FORCE Technology is authorised to carry out inspections higher than 100 meters.

An example is the inspection of a 225 meter chimney and masts at a power station, refinery or hydro power plant. Another area clearly suitable for drone inspection are bridges, irrespective of their being on land, connecting islands or spanning divisions in a landscape.

Additionally, drones are delivering good results with the increasingly taller wind turbines. In particular, leading edges, lightning receptors and nacelles are subjects for inspection. Here the drone collects high resolution pictures of possible defects, making it possible to plan repair work in detail as the data collected will help avoid unpleasant surprises during the maintenance period.

3. Confined spaces

Confined spaces such as boilers at power plants, storage tanks for fuel etc. are a relatively new addition to the drone inspection area, but are gradually becoming more commonplace. Here visual inspections are advantageous if it is too expensive or time consuming to set up a scaffold, or too hazardous for physical inspection.

There are though considerable challenges when using drones in confined spaces, these include lack of proper light condition, colour nuances, reflection of radio signals and propeller turbulence.

We meet these challenges by using powerful LED lamps, thus ensuring good picture quality with true, natural colours, as well as using specialised equipment and experienced pilots who can predict areas with high risk of turbulence.

The drone collects picture- or thermographic data of the flare&#;s condition, while it is in production. Drone inspection of chimney reveals corrosion areas and cracks in the concrete.

The technical possibilities

Today there are both simple drones which can record video or take still images, and advanced drones, to which all types of data collecting equipment can be attached.

It is especially relevant to choose the advanced drones when measuring flue gas emissions, or inspecting wind turbines, where a thermographic camera can detect delaminating, that is to say the internal composite layers separating beneath the surface of the wing.

We have in recent years also used the thermographic camera to inspect house roofs, electrical and production installations, facilitating the detection of heat related faults or defects.

Only experts ought to analyse data

The drone inspection itself is normally quickly finished. Most of the work lies in the analysis of the data collected, and the pictures from the drones. It is essential here to enlist relevant experts in analysis to obtain the full value from a drone inspection.

Someone lacking the necessary qualified experience may overlook a critical defect or fault, possibly with fatal consequences. For instance, an inspection concerning a steel construction requires an expert metallurgist to analyse and interpret the collected data.

An inspection report is produced, based on the analysis of this data, and is usually divided into categories of red, yellow and green priority according to the seriousness of the damage. This report can if needed include a service plan, with recommendations to cost-effective improvements.

Drones for almost everything

As explained in this article, it is especially offshore, onshore and increasingly within confined spaces, for which drone inspection is the first choice. Though, we will always together with the client clarify if the drone inspection is the correct choice according to the nature of the problem and the data required.

Accepting that an extensive and important part of a drone inspection is the analysis of the collected data and picture material, one must be able to ensure that the person conducting the analysis is an expert in this field.

The client should therefore require references from both the drone inspector and the data analyst.

What Factors Are Assessed With Drone Testing - Biokinetics

With the commercial use and application of drones seeing increased interest across North America and Europe over recent years, regulatory bodies have faced the challenge of rapidly adopting and implementing safety standards that allow for optimal performance and the protection of civilians. Unmanned aerial vehicles (UAVs) have plenty of benefits for distributors to make use of, but in order to ensure their reliability, safety, and effectiveness, thorough testing and evaluation measures are crucial. 

Below, we&#;ll take a look at the importance of drone testing, as well as common types of standardized testing that are conducted to build the safest (flight) path forward. Read on to learn more!

Why Does Drone Testing Matter?

As we mentioned above, drones have become increasingly popular for commercial applications thanks to their efficiency and ability to remove the need for extra manpower to facilitate transport or operations. With usership on the rise, regulatory compliance is crucial for risk mitigation and the optimization of drone performance. Testing helps to identify existing risks, as well as shape the future of drone technology by removing ambiguity, assessing reliability and providing dependable data to build upon. 

Drone testing is particularly vital in industries where there is a much higher risk of harm, such as when being used for defence or aerospace purposes. In such cases, drones are used for highly technical and hazardous endeavours. While there is an undeniable benefit to being able to remove a human operative from the front line of harm, there are also significant civilian risks associated with reconnaissance and offensive measures. Testing is essential to understanding the capacity and limitations of drones, as well as understanding how to best use them to the benefit of all parties involved.

Types of Drone Testing

There are several different types of drone testing, each of which focus on different attributes and considerations. Key areas of evaluation include:


Functionality

Performance testing

Performance testing assesses speed, endurance and agility to ensure the unit is able to perform as intended with minimal issues.

Environmental testing

Climate and environmental factors can put strain on drone systems and pose a heightened risk if units are unable to sustain safe flight/operation in the face of changing conditions. Wind resistance, humidity, vibration, altitude and electromagnetic interference are all potential hazards to be analyzed in order to guarantee that the drone is capable of operating in adverse conditions. 

Safety testing

Safety testing is a necessity and regulatory obligation regardless of the capacity or environment a drone will be operating. A thorough evaluation is undertaken to assess the drone&#;s fail-safe mechanisms, emergency procedures, obstacle detection and avoidance systems, and comprehensive risk mitigation strategies.

This is by no means an exhaustive list of testing varieties, and units operating within highly specific circumstances may be subject to additional testing measures tailored to their unique purposes.

Common Testing Challenges 

As with any complex safety testing, drone evaluation is not without its share of challenges when it comes to standardizing results. Common challenges include: 

Integrating Drone Operating Systems

Drones utilize multiple systems, sensors and software during operation, and creating a standardized form of regulation for the wide array of complex systems in place can be exceedingly difficult.

Regulatory Compliance

Drone testing must be specifically tailored to adhere to, and address the concerns and rules levied by regulatory organizations. Results must also clearly display how units abide by existing standards and be adaptable to continuous changes as new safety risks become known. 

Scalability &#; Adaptability

Drone technology continues to evolve at a rapid pace, and regulators, manufacturers, and testers need to be able to seamlessly adapt to and integrate new platforms, configurations, and payloads. Scalable testing methods allow for efficient evaluation and validation of emerging drone technologies, allowing users to benefit faster.
