Denley has, over the last half a century, developed an internationally recognised reputation in the international offshore oil and gas industry for the delivery of safe, reliable and cost-effective electro-hydraulic engineering systems, products and services that are highly imaginative, individually tailored and often ground-breaking.

Denley is a BSI firm, whose quality management systems control of all its design, manufacturing and installation operations in full compliance with ISO 9001:2008.

Moreover, in its drive to continually improve its present procedures and standards, such as utilising new materials, technologies, safety issues and system design, as well as the on and off-site integration of all third party supplier procurement, detailing, installation and maintenance co-ordination, Denley is also approved to many of the industry’s individually tailored quality standards.

Electro-hydraulic power systems, high-pressure instrumentation panels and manifold block options and valves

Denley’s global expertise in the oil and gas industry covers not only large, centralised electro-hydraulic power systems, but also their associated and often extremely complex, high-pressure control and instrumentation panels, complete with a wide range of standard, custom-built and special-purpose manifold block options and valves.

Single and double-acting heavy-duty hydraulic cylinders

The company’s innovative design and engineering capabilities also provide a technologically advanced hydraulic cylinder and actuator (both top-side and sub-sea) design, testing and manufacturing facility, including the delivery of many standard, but more often project-specific, single and double-acting heavy-duty cylinders.

Denley’s comprehensive range of core competencies is not only the foundation upon which the company has built a technically strong and strategically complete customer services capability and expertise in the oil and gas business over the years, but more importantly, it is the basis upon which customers have grown to trust and rely on the Denley brand to deliver imaginative, operationally practical and safe electro-hydraulic engineering solutions.

Bespoke electro-hydraulic systems

Many of the highly bespoke products designed and manufactured for the international oil and gas industry by Denley are not only safety-critical and subject to dramatic extremes in temperature, but also open to some of the harshest elements on earth.

Here, equipment performance and reliability, including the material’s ultimate specification and resistance to such harsh, hazardous, corrosive and environmentally challenging environments, are always at the forefront of Denley’s quality control, design, testing and manufacturing protocols.

Rig machinery, tooling, actuators and control and instrumentation equipment

Specific to the offshore oil and gas industry, Denley’s market knowledge and engineering skills extend to a full range of general operational equipment, including specialist machinery, tooling, instrumentation and control equipment of, for instance, a platform’s large centralised power unit, which is necessary to the running, supply and control all the hydraulics on one of today’s modern rigs.

Denley can also supervise the development and supply of specialist and safety critical umbilical (platform to seabed) termination panels, where equipment performance and reliability are absolutely crucial.

Other examples of Denley’s offshore engineering capabilities include the design and production of cantilever SKID power units, which are used to facilitate the movement of equipment around the deck area, as well as the production of HTV arm gripper beams used in the handling of a rig’s drill pipe sections, all of which have to be extremely durable, safe and structurally sound in their design, material specification and operation.

International brand presence

Denley’s predominately international customer base is founded on a well respected and imaginative electro-hydraulics engineering design and build partnership, whose market presence is also seen as innovative, flexible, reliable and totally open in terms of customer access, inclusion and delivery. Its brand features can bring huge benefits to more bespoke and elaborate engineering requirements.

The company’s extensive resources, market expertise, core competencies and skill sets enable it to deliver the highly specialist services of imaginative design solutions, project management, systems and prototype engineering, installation and commissioning, maintenance, repairs and upgrading across a wide range of internationally spread offshore applications, where safety critical, technically demanding and high-value materials form the basis of each individual customer’s project requirements.
