Horizontal Directional Drilling (HDD) Companies

We are proud of being a world-class independent management, engineering and development consultancy. Being independent, wholly owned by our people, puts us in charge of our own journey and allows us to focus on what we believe is important for our clients, our colleagues and the communities we work and live in. We have more than 100 years’ experience in the water sector and are experts in every aspect of water development, with all the skills and commitment to deliver solutions that benefit every stakeholder.  We also established Mott MacDonald Bentley more than twenty years ago to deliver long-term programmes of work through a strategic focus, effective communication and flexibility in different models of working.  We are experts at building a trusted relationship with our clients. From investment planning to operational support, design to capacity building we work with private investors and listed companies, as well as national and local governments across the world in both developing and developed regions. As advisors, we think laterally and find the connections that others fail to make. We are pioneers with a thirst for innovation, who understand the challenges facing the water industry today, including biodiversity net gain, natural capital and ecosystem services, the practicalities of the journey to net zero, nature-based solutions and natural flood management and the need to consider everything from a fresh angle and turn obstacles into sustainable paths for both businesses and the lives they touch every day.

Pipelife is an established and well respected supplier of polyethylene pipes and recognised as a global leader in the supply of long length extruded solid wall PE pipes. Our long length extruded pipes are produced by Pipelife Norge in Norway. The large, high-quality pipes are extruded at our Stathelle plant using premium PE100 resins and strict factory quality controls. Each pipe is made to order through a seamless, continuous extrusion process that eliminates welds and extends directly from the factory into the fjord. From there, the pipes are transported by tugboat straight to their destination, removing the need for land storage or extensive working areas. This efficient production and delivery method not only ensures exceptional durability and precision but also reduces handling and lowers the overall carbon footprint, making Pipelife a reliable partner for major infrastructure projects worldwide. Located on the shore of a sheltered fjord, Pipelife’s Stathelle plant offers the ideal setting for producing long-length pipes. Its coastal position allows continuous production in a clean, controlled environment with direct access to the sea, meaning pipe lengths are limited only by the fjord’s size and the pipe’s diameter. The facility is equipped with extensive storage areas on both land and water, along with a dedicated wharf for easy loading by ocean-going tugs. Supported by Norway’s reliable infrastructure, the plant benefits from a stable energy supply and consistent access to essential raw materials. Inside, a state-of-the-art production line, enhanced with specialized modifications, ensures the highest manufacturing standards and delivers unique advantages in product quality and performance. Pipelife’s long-length, large-diameter pipes are designed for a wide range of demanding applications, including: Wastewater sea outfalls and diffusers Desalination and power plant intakes and outfalls Cable landfalls Cable protection systems Horizontal directional drilling (HDD) liner ducts Fish return lines
