Hornsea 3 Offshore Wind Farm, UK

We supplied 394 FOHO (Foot-Operated Hatch Opener) units to Ørsted’s Hornsea 3 Offshore Wind Farm, engineered to enhance the safety of vertical access within the turbines.

Designed in partnership

Following extensive demonstrations and testing of our new Hatch System, we worked closely with Ørsted to further refine the solution, advancing its design to enhance worker safety within the Hornsea 3 turbines. This collaborative approach allowed us to tailor the system’s performance to real-world operational demands while maintaining the robustness required for offshore environments.Part of this customisation involved developing an alternative fixing method, enabling fast and secure installation with minimal disruption to the turbine’s internal layout. Combined with the Hatch System’s low-maintenance mechanism, this solution ensures long-term reliability without adding operational burden for technicians.Crafted from high-grade corrosion-resistant aluminium and stainless steel, the Foot Operated Hatch System is tested beyond 10,000 cycles, ensuring dependable performance throughout the turbine’s operational life.

Working to improve hatch safety

By enabling operators to open the hatch without using their hands, the Hatch System significantly reduces risk during vertical movement, offering safer access than traditional pulley-and-weight systems. Its self-closing feature eliminates uncontrolled slamming, further improving safety.

Delivering value on one of the UK’s flagship wind projects

Supplying Hatch Systems to a major project like Hornsea 3 reinforces Gatemaster’s role as an innovative, safety-first partner in the offshore wind industry. This collaboration demonstrates our ability to deliver purpose-built, high-performance hardware to large-scale renewable projects, helping to set new standards for vertical access safety.

RAAF 135th Radar Station Tower, Australia

Gatemaster Offshore supplied purpose-engineered hatch solution to the RAAF 135th Radar Station Tower in Pinkenba, Australia. Designed for controlled, secure hatch operation, our solution was adapted to meet the structural and environmental demands of this critical infrastructure site.

Bespoke, engineer-led adaptation

Working in close collaboration with AMS Australia, our team developed a tailored solution to suit the unique configuration of the tower hatches.The primary engineering challenge was the limited fixing point available on the structure. The only viable mounting location was the grating adjacent to the hatch. A standard configuration was not suitable.In response, our engineers redesigned the hatch stay to mount beneath the hatch itself, preserving the core functionality and performance characteristics of the original design while introducing a completely new form factor.The result was a bespoke, custom-engineered product that delivered the same controlled opening and secure hold-open performance, adapted precisely to site constraints. This is where our engineer-led approach adds value. We do not offer one-size-fits-all hardware. We develop reliable solutions built around your structure.

Engineered to withstand coastal extremes

Located on a coastal area near Brisbane, the radar station is exposed to intense storms, high winds, salt-laden air and prolonged humidity, particularly during spring and summer months.Every Gatemaster Offshore product is engineered to defy the elements. Our hatch hardware undergoes comprehensive testing and inspection to verify corrosion resistance, mechanical integrity and long-term reliability.Manufactured from high grade stainless steel and finished for maximum durability, our solutions are built to last in aggressive environments, whether installed on offshore platforms or critical land-based structures.Safe access hardware must perform without compromise. Your safety and operational continuity are our priority.

Delivering safe access

This project demonstrates the adaptability of our hatch hardware across demanding sectors. By working closely with our client and re-engineering our product to suit the application, we delivered a robust, safety-focused solution without sacrificing performance.For engineers and project managers facing structural constraints or harsh environmental conditions, we offer more than components. We offer collaboration, technical expertise and bespoke products engineered to last.Tell us about your project. Let’s develop a hatch and gate hardware solution built around your exact requirements.

Kollsnes Processing Plant, Norway

A bespoke hatch system for a demanding coastal environment

At the Kollsnes Processing Plant on the coast of Norway, safe hatch operation was a critical requirement within a harsh and demanding industrial setting. The combination of exposed coastal conditions, high winds, and heavy grating materials created added risk for operators and made a standard solution unsuitable for the site.Gatemaster worked closely with the client to develop a bespoke hatch system tailored to these conditions and the specific challenges faced by the plant team. The aim was not only to improve day-to-day usability, but also to deliver a safer, more reliable solution that could perform consistently in a tough operating environment. By combining practical engineering with a clear understanding of the site’s safety needs, the project resulted in a custom hatch solution designed to support safer access and long-term performance.

Designed around the site’s safety challenges

From the outset, the client identified two key safety concerns that needed to be addressed during hatch operation. The first was the need for operators to lean over the hatch opening while using it. The second was the risk of the hatch falling during operation.In an environment like Kollsnes, these risks were heightened by strong winds and the weight of the hatch materials, making safe and controlled movement even more important. The solution therefore needed to reduce operator strain, improve control, and provide greater confidence during use.

A custom hatch solution built for safer operation

To address these challenges, Gatemaster developed a bespoke hatch system with an integrated spring lift assister to reduce the force required to open the hatch. This made operation easier and more controlled from above, while also supporting safer exit when climbing up from below.The system was manufactured from premium-grade stainless steel chosen specifically for offshore and coastal environments. This ensured the hatch stay solutions could withstand corrosion, extreme weather exposure, and continuous operational demands without compromising reliability. The result was a durable, high-performance system built to deliver long service life in a challenging chemical processing environment.

Delivering long-term value through tailored engineering

The finished solution successfully met the client’s safety requirements while demonstrating the value of a tailored engineering approach. Rather than adapting an off-the-shelf product, Gatemaster delivered a custom hatch solution designed around the realities of the site, its environment, and the needs of the people using it.The Kollsnes project reflects Gatemaster’s commitment to engineering practical, high-quality safety solutions for complex industrial applications. Through close collaboration and site-specific design, we continue to develop hatch stay solutions that improve safety, reliability, and performance in demanding environments.
