Coastal and Marine Sector Drone Services

Asset inspections, surveys, mapping, modelling and more in the coastal and marine sector.

Safer coastal and marine inspections and surveys with zero downtime

We have worked with some of the biggest names in Ireland's coastal and marine sector. Our engineers have years of experience carrying out inspections and surveys of all kinds of assets, structures and landscapes. They understand the critical need to minimise downtime while guaranteeing the safety of all personnel and operational assets on site. Tell us what you need. It's our job to deliver it for you.

Ports & harbours Coastal defences Marine structures Environmental Elevation mapping

Ports & harbours

Drones can inspect, survey and map critical port and harbour infrastructure with precision and speed. Using the latest technologies, our engineers can conduct aerial and underwater drone surveys of piers, docks, cranes and other maritime facilities. Whether you're looking to identify corrosion, assess structural damage or streamline operational inefficiencies, our engineers can produce quick, accurate and actionable deliverables in a format that enables optimal decision-making for you.

Industrial port cranes

Aerial surveys for structural integrity

Fitted with the latest high-definition cameras, our UAVs can inspect cranes, docks and above-water infrastructure for signs of corrosion, cracks or other structural wear. This reduces the need for scaffolding or manual inspections, improving safety and minimising disruption.

Underwater inspections with submersible drones

With sonar and high-resolution imaging payloads, our submersible drones can gather data on the condition of submerged structures like pilings, sea walls and mooring points. Carried out by experienced engineers, these inspections can detect erosion, marine growth and structural damage in areas that are difficult or hazardous to access manually.

Environmental monitoring

Drones equipped with multispectral imaging and water quality sensors allow our engineers to monitor sediment movement, water pollution and ecological impact near ports and harbours. We can give you raw data or expert analysis. Either way, this data can support compliance with environmental regulations and sustainable operation.

Efficiency and operational insights

By capturing real-time aerial data, drones can provide insights into cargo handling, traffic flow and overall operational efficiency. Such insights can help to optimise workflows and identify potential bottlenecks in port operations.

Coastal defences

Monitor the condition and performance of critical coastal defence infrastructure, including embankments, sea walls and barriers. Using LIDAR , photogrammetry and thermal imaging, our experienced engineers can assess erosion, structural damage and potential weak points. This data enables proactive maintenance and supports effective coastal risk mitigation.

Precision mapping with LIDAR and photogrammetry

Drones equipped with LIDAR and photogrammetry payloads provide detailed topographical surveys of coastal defence structures and surrounding terrain. Our engineers can use this data to detect soil displacement, erosion or uneven settlement that might compromise the integrity of embankments or sea walls.

Structural assessments with thermal imaging

Thermal imaging technology can identify subsurface anomalies in coastal defences, such as moisture penetration, cracks or voids. This allows our clients to detect early signs of failure and address them before they escalate.

Monitoring water flow and sediment

Using drones with multispectral imaging and water quality sensors, our engineers can monitor sediment accumulation and water flow near coastal barriers or spillways. This information helps identify blockages or imbalances that could impact the effectiveness of the coastal defences.

Emergency response and post-event analysis

During and after coastal events, drones can rapidly survey affected areas to assess damage and guide emergency response efforts. Our engineers can work with you in the field to guide the recovery process and provide expert analysis of any damage.

Marine structures

Inspect marine structures such as offshore platforms, wind turbines, and underwater pipelines with advanced drone technology. Our engineers use a combination of aerial and underwater drones equipped with high-resolution cameras, sonar and thermal imaging to detect structural issues, corrosion and other potential problems.

Aerial inspections for offshore platforms

Drones equipped with high-definition cameras can capture detailed imagery of offshore platforms, identifying corrosion, structural damage and other issues. This reduces the need for manual inspections, improving safety and efficiency.

Underwater inspections with sonar

Submersible drones equipped with sonar and high-resolution cameras can inspect underwater structures, such as pipelines and wind turbine foundations, for damage, corrosion and blockages. This technology provides critical insights without the need for divers or costly shutdowns.

Thermal imaging for structural assessments

Thermal imaging technology can identify subsurface anomalies in marine structures, such as moisture penetration, cracks or voids. This allows our clients to detect early signs of failure and address them before they escalate.

Environmental monitoring

Monitor coastal and marine environments with advanced drone technology. Our engineers use drones equipped with multispectral imaging, thermal cameras and water quality sensors to track ecological changes, identify sources of contamination, and ensure compliance with environmental regulations.

Multispectral / LIDAR for ecological monitoring

Drones equipped with multispectral imaging or LIDAR can monitor vegetation growth, water quality and pollution levels in coastal and marine environments. This data helps track ecological changes and identify sources of contamination.

Thermal imaging for environmental assessments

Thermal cameras can detect temperature anomalies in water bodies, helping to identify sources of pollution and monitor the health of marine ecosystems.

Water quality monitoring with sensors

Drones equipped with water quality sensors can monitor parameters such as pH, turbidity and dissolved oxygen levels, providing critical data for environmental assessments and regulatory compliance.

Elevation mapping for coastal and marine environments

Coastal environments change continuously — erosion, accretion, storm surge, and sea level rise reshape the shoreline with every tide. A LiDAR survey captures millions of survey-grade measurements across the coastal zone in a single flight, producing a digital terrain model that can be compared against future survey dates to quantify exactly how much material has moved and where.

  • What is the difference between a DSM and a DTM for coastal assessment?

    A digital surface model (DSM) includes everything on the ground — vegetation on dunes, structures on the shoreline, rock armour on breakwaters. A digital terrain model (DTM) represents the bare earth with all surface features removed. Both are generated from the same LiDAR point cloud.

    For coastal engineers, the DTM reveals the underlying profile of dunes, cliffs, and beaches without vegetation obscuring the true slope. Comparing a DTM from before and after a storm event quantifies the volume of sand lost from a beach or dune system. The DSM captures the condition of coastal defence structures — rock armour displacement, seawall deformation, breakwater settlement — that a photograph alone cannot reliably measure.

  • What does an elevation heatmap tell me that a photograph of the coast does not?

    A photograph of a coastline can be misleading. Shadows from cliffs, reflections off wet sand, and vegetation on dunes can hide the true shape of the terrain. An elevation heatmap replaces colour with absolute height data — every pixel has a known Z-value — so dune crest lines, cliff edge retreat, and beach profile changes are unambiguous.

    For coastal management, this is particularly useful for mapping the Mean High Water Mark for legal boundary purposes, identifying sections of dune system that have been eroded below a critical threshold, and tracking longshore drift patterns by comparing beach profiles between survey dates. The heatmap turns a shoreline walkover into a measurable engineering dataset.
