Helix overview We are an international offshore energy services company that provides specialty services to the offshore energy industry, with a focus on well intervention and robotics operations. Traditionally, our services have covered the lifecycle of an offshore oil or gas field. In recent years, we have seen an increasing demand for our services from the offshore renewable energy market. Whether it's well intervention, subsea robotics, subsea trenching and cable burial or seabed clearing services for the offshore renewable energy sector, we can provide the specialty services you need. We have decades of experience in the industry and are constantly seeking new and innovative ways to deliver on every project. • 1,500+ well interventions • 30+ offshore wind farm trenching projects • Decades of experience We provide services primarily in deepwater in the Gulf of Mexico, Brazil, North Sea, Asia Pacific and West Africa regions.
