Heavy-dutycompensators
Rugged subsea compensator series for extreme conditions
Overview
Compensator range able to withstand the most severe operating conditions
Although operating conditions in the offshore and dredging industry are rough to begin with, certain operations put even higher pressures on teams and their equipment. Shock loads, vibrations, temperature variations, and dirt result in particularly profound impacts on mechanical assemblies. To enable proper operations of a hydraulic system under these harsh conditions, Seatools developed the heavy-duty compensator series. These subsea compensators are constructed from stainless steel, and withstand the most extreme of conditions. A case in point is the Grab Excavation System. In the context of this project, Seatools successfully applied its heavy-duty compensators.

To ensure that the right size and type of compensator is selected, we advise our clients during the selection process. We do so, taking temperature ranges, pressure ranges, filling levels, entrapped air, fluid behaviors, and other factors into account.
Key Features
-
Designed for the toughest operating conditions
The heavy-duty series compensators excel in extreme operating environments. They withstand impacts from shock loads, vibrations, temperature variations, and dirt.
-
Highly reliable design
Our heavy-duty compensators have been constructed from stainless steel, and their designs incorporate our extensive knowledge about subsea pressure compensators.
-
High degree of customization
The heavy-duty range can be configured according to your application and requirements. Adjustments can be made with variations in hydraulic connections, electric connectors, oil level measurement, relief valves, discharge collectors, mounting components, required quality standards and classifications, and maximum operating depths.

Basic Series
A range of cost-effective underwater pressure compensators that feature a light-weight design and volumes ranging from 0.6 to 6 litres. Because mass constitutes an important criterion in the construction of ROVs, our light-weight basic series compensators are a perfect match for ROV applications.
Advanced compensators
High-end subsea hydraulic compensators with compensation volumes ranging from 0.6 to 15 liters. Time-proven, highly reliable, and solid designs that facilitate relatively high overpressures. Largely customizable, with options for hydraulic connections, electric connections, level measurement, and more.
Ultralong lifetime series
Hydraulic compensators for permanent subsea applications, such as a control fluid reservoir for subsea production systems. Thanks to their ingenious design, a minimum of moving parts is exposed to sea water, which results in a compensator lifetime of over 20 years. Compensator capacities range from 20 to 200 litres.
