Ever since our establishment as Hydranor in 1962, we have delivered robust and reliable blocks to a wide range of sectors. The technology used in our blocks has been thoroughly tested over many years by the most demanding offshore and marine customers. In our design, we have strengthened the most exposed parts in the block with stainless steel components. This further increases the lifespan of our blocks. 

Plug and play – installation and maintenance

All of our hydraulic products is delivered with supplementary documentation, which simplifies installation and maintenance. 

The hydraulic valves are compact and have integrated functions. This simplifies installation and makes the products cost-effective. In addition, the design contribues with fewer leakage points, which reduces the need for maintenance. 

The documentation is user-friendly and the product easy to use, resulting in a winch block with long service life and enhanced performance. This is also in line with Servi’s life cycle philosophy.

Our hydraulic valves for the marine sector are mostly used for:

Surface treatment

We can deliver all types of surface treatments, including painting, after the customers choice.

All of our blocks are 100% function and pressure tested in accordance with customer requirements.

 

Lifecycle Extension of Hydraulic Blocks

After many years in use, this block came in for service and overhaul in Kongsberg. It was disassembled and sandblasted, then received new seals and valves where needed. After surface treatment and testing, it was sent back to the customer for many more years of use. Sustainable in multiple ways.
