Bridge & Jetty Inspection Services

A Vertech Group technician, wearing an orange high-visibility suit and a white safety helmet, inspects a large column under a jetty. The column is marked with a grid pattern for precise measurement, while the technician uses a handheld inspection device to assess its condition. The technician is secured with ropes and a safety harness, demonstrating the focus on safety and attention to detail during critical maintenance operations in a challenging environment.
Non-Destructive Testing (NDT)
Aerial view of a large jetty extending into a calm sea, part of an expansive industrial facility on the coast. The jetty has multiple platforms and yellow safety railings, stretching towards the horizon where large storage tanks and industrial structures are visible. The coastal environment showcases a mix of clear blue waters and mangroves under a bright sky, highlighting the facility's strategic placement and extensive operations.
UAV & Marine Drone Inspection
Two RDVI crawlers equipped with a spotlight are shown inside a pipe. The crawlers, used for remote digital visual inspection, feature compact bodies, wheels, and various attached components. The light from the spotlight illuminates part of the pipe's interior, highlighting its smooth, curved metallic surface while creating contrasting areas of shadow. The equipment's orange cables and chassis are visible against the pipe's dark background.
Remote Digital Visual Inspection (RDVI)
A view of alternative access decking installed beneath a jetty pier. The narrow blue platform decking is suspended under the dock and provides safe access for workers to carry out maintenance or inspections. The jetty extends into the ocean, supported by large pillars that elevate the structure. The clear blue water surrounds the pier, while steel cables reinforce the decking. A metal railing and various pieces of equipment, such as ropes and nets, are visible on the jetty.
Coating & Integrity Inspection
A 3D photogrammetry model of a mining jetty, presented against a black background. The model accurately captures a long conveyor system used to transport materials supported by robust metal structures. The jetty extends over a pile of raw materials, possibly minerals or aggregate, on the right side of the image. The central section of the conveyor is elevated, with a small building and equipment visible. The left end of the jetty includes a processing or loading station with machinery. The model showcases detailed spatial data of a bulk material handling or mining facility.
3D Digital Twin & Engineering
Two Vertech Group technicians stand on a dock next to a body of water. They are dressed in bright orange safety gear and prepare an underwater remotely operated vehicle (ROV) for deployment. The technician on the left, wearing a grey cap, is focused on the ROV, while the technician on the right, wearing a black cap, supervises. Behind them, various small boats are docked along the pier, and the clear blue water reflects the sky and surrounding marina. The scene showcases the specialised underwater inspection equipment and the team's professional approach.

Two Vertech Group technicians are suspended from ropes working on a metal structure above the ocean. The structure, which appears to be a jetty or offshore platform, features large angled support beams. The technicians, clad in bright orange safety gear and helmets, are positioned near the bottom of a vertical beam that extends into the sea. The calm, turquoise ocean provides a picturesque backdrop, while the sunlight shadows the structure, highlighting the intricate engineering and the technicians' rope access skills.
Specialist & Rope Access
Two Vertech Group technicians in bright orange safety gear are suspended from ropes while working on large structural beams above the ocean. One technician uses a grinder, sending a spray of sparks into the air, while the other is seated on a metal platform, closely observing the work. The scene highlights the technicians' skilled rope access and precision engineering work, set against a backdrop of a vast blue ocean, underlining the challenging and dynamic nature of their offshore jobs.
Mechanical Fitting
A view of the underside of a jetty pier featuring alternative access web decking. Vibrant chains and clamps in colours like green, pink, and orange are used to create a sturdy network for support and safety. The web decking provides a safe working platform, with protective sheeting covering the floor. This setup demonstrates meticulous planning and execution to ensure stability and safety during maintenance or construction operations beneath the pier.
Painting & Blasting
A view of wrapping on jetty pier supports, showcasing several interconnected struts covered in a protective wrapping material. The wrapping provides corrosion protection and durability in a marine environment. The pipes are positioned on a platform above clear turquoise water, highlighting the importance of safeguarding industrial infrastructure in challenging conditions.
Composite Wrap Application
A Vertech Group rope access technician is suspended in mid-air beneath a massive industrial platform, wearing an orange suit and safety helmet. The technician is secured by a complex system of ropes and harnesses, allowing him to perform maintenance work on the underside of the platform. In the background, another technician can be seen in a similar position, while an industrial facility and a large ship are visible in the distance over turquoise waters.
Concrete Remediation
Two Vertech Group technicians in yellow and navy high-visibility jackets and white safety helmets discuss an inspection project while standing on a rocky shore.
