INTERNAL USE - Case Study teixeira_duarte imagem_ponte

The rehabilitation of Brazil’s iconic Hercílio Luz Bridge demanded a custom structural monitoring approach to ensure both safety and preservation of its nearly century‑old design. Tasked with this complex restoration, Teixeira Duarte partnered with HBK to deploy advanced Fiber Bragg Grating (FBG) optical sensing technology alongside a suite of electrical sensors to monitor strain, inclination, temperature, wind, and sea conditions in real time.

INTERNAL USE - Case Study iter ITER_345x345px

ITER is an international fusion experiment aiming to demonstrate a new, clean, and sustainable source of power. HBK was entrusted with the supply of advanced optical strain‑gauge measurement systems designed to perform in some of the harshest conditions imaginable—extreme radiation, vacuum environments, powerful electromagnetic fields, and cryogenic temperatures.

Train passing through a rural landscape with many tracks

DB Systemtechnik, the independent testing authority of Deutsche Bahn, is exploring how HBK’s optical strain‑gauge technology could transform the way wheel‑rail forces are measured during railway vehicle approval testing. Traditional electrical strain‑gauge installations require extensive wiring, drilling, and weeks of labour per wheelset—adding cost, complexity, and mechanical risk. By using optical strain gauges, the company aims to significantly reduce installation time, minimise structural intervention, and enhance safety.

HBK engineers installing fiber optic strain gauge on the shaft of the IMOCA Advens yacht before the Vendée Globe race

For the Vendée Globe sailing race, the Advens for Cybersecurity IMOCA team partnered with HBK to develop and install advanced optical strain‑gauge technology for their boat’s high‑performance foils. As these next‑generation foils lift the hull to reduce drag and increase speed, understanding their structural behaviour is critical—especially in the extreme conditions of solo, nonstop, round‑the‑world racing. HBK’s engineering specialists collaborated with the boat designers to create a customised Fiber Bragg Grating sensing solution capable of delivering precise, reliable measurements under intense mechanical and environmental stress.

At Spain’s Endesa Hydroelectric Plant, HBK delivered high‑precision optical measurements under extreme environmental and time‑critical conditions. Tasked with installing a thermally compensated FBG‑based strain monitoring system on a steel adduction pipeline—spread across remote sections and hundreds of meters from the control room—the team completed the full deployment in just three days.

INTERNAL USE - Case Study iat-earthsystems RaBoe_Wikipedia_Santa_Maria_del_Suffragio_2010

When an earthquake reduced L’Aquila’s historic Santa Maria del Suffragio church to ruins, engineers faced a delicate challenge: rebuild a landmark while ensuring its long‑term structural resilience. To support the seismic reinforcement of the centuries‑old structure, HBK deployed advanced optical FBG sensing technology to monitor strain and temperature in critical pre‑stressed tie rods—providing continuous, high‑resolution insight where precision was non‑negotiable.
