Offshore hydraulic systems engineering
Hunger Hydraulics’ project engineers handle the whole process of an offshore project from the first customer advisory session, through to engineering, certification (according to DNV, Germanischer Lloyd, etc.) and finally production. Project engineers also provide the important services of commissioning and repair.
Hunger Hydraulics has acquired an 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.
Customized 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 for designing customized hydraulic cylinders and complete hydraulic system solutions according to 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 the following Hunger coating systems:

Ceraplate
Ultraplate

Specifications and properties of the coating systems are as follows. For Ceraplate:

Sprayed layer
Provide a corrosion resistance above chrome or NiCr coatings
Suitable for on-deck installations (DNV classification I or II)

For Ultraplate:

Welded layer
Provide a corrosion resistance above the Ceraplate
Suitable for splash zone of submerged condition (DNV classification III)
DNV approved

Since the establishment of the Hunger Group in 1945, quality and reliability, combined with due consideration of special customer requirements, have formed the core of the company’s vision. This philosophy has developed to become the hallmark of Hunger Hydraulics’ products.
