• Accumulators
• Rotary actuators
• Rotary transmissions
• Special valves
• Pressure intensifiers
• Hydraulic control blocks
• Piston rod coatings
• Telescopic masts for fire-fighting systems
• Drive and control units
• Seals, wipers and bearing elements

Hunger Hydraulics' manufacturing capacities for hydraulic cylinders permit machining diameters up to 4m, machining lengths of 25m and weights up to 70t per workpiece.

Applications in the offshore hydraulic industry

Hunger Hydraulics' project engineers design cylinders and systems solutions for many different offshore applications including:

• Offshore cranes
• Jacking systems
• Direct and wire riser tensioner systems
• Heave compensating systems
• Piston accumulators
• Telescopic lift systems for fire-fighting monitors
• Shore flood defence installations

Hunger Hydraulics also offers the modernisation of existing hydraulic equipment together with the replacement or repair of damaged cylinders or accumulators.

Offshore hydraulic system engineering

Hunger Hydraulics' project engineers handle the entire process of an offshore project, from the first customer advisory session through to engineering, certification (according to DNV, Germanischer Lloyd's, etc.) and production. Project engineers also provide the important service of commissioning and repair.

Offshore hydraulic systems and surface-coating technology

Hunger Hydraulics has acquired in-depth knowledge of offshore hydraulic systems and of the developments in offshore surface-coating technology. Moreover, the company has developed its own in-house processing methods. With all this experience and expertise, Hunger Hydraulics is the right partner for the offshore industry.

Customised hydraulic cylinders

Hunger Hydraulics' wide-ranging experience in offshore projects provides customers with technological advice in the selection of special application-related hydraulic solutions, especially in the region of hydraulic cylinders. Hunger Hydraulics is a specialist in the design of customised hydraulic cylinders and complete hydraulic system solutions according to its customers' needs.

Piston rod coatings

The climatic and environmental requirements of offshore applications demand special anti-corrosion coatings for piston rods. Hunger Hydraulics has successfully used piston rods in many offshore projects and, using that experience, has developed two Hunger coating systems: Ceraplate and Ultraplate.

Offshore anti-corrosion coating for piston rods

The Ceraplate coating system for piston rods has a sprayed layer, provides a corrosion resistance above chrome or NiCr coatings, and is suitable for on-deck installations (DNV classification I or II).

The Ultraplate coating system has a welded layer and provides a corrosion resistance above the Ceraplate, is suitable for splash zone of submerged condition (DNV classification III), and is DNV-approved.

Inside coatings for tubes and bore surfaces

Hunger also offers various inside coatings for tubes and bore surfaces, which alternatively protect from corrosion and / or wear. If you want to learn more about our surface coating systems and our wide variety of inside coating selection don't hesitate to contact us.
