Seatools adds to compensator range

26 December 2016 , 13:28Neftegaz.RU264

Seatools, a Dutch subsea technology company, introduced their new subsea hydraulic compensator range: the Advanced series.

This subsea compensator range, based on the preceding Hyco range, is designed for improved robustness, durability, and standardization.
The Advanced series is based on the preceding Hyco range, and is meant for heavy-duty subsea hydraulic systems - such as subsea vehicles (e.g. ROVs [remotely operated vehicles] and trenchers) and dredging systems (suction tube SHPU [subsea hydraulic power unit] compensation) - features an improved mechanical design.

After reviewing its design for exposure to extreme temperatures and long-term material behavior, several improvements were made in the areas of mechanical design and material selection.
The range's revised design, largely based on stainless steel, facilitates higher pre-pressures, which reduces the risk of water and air ingress and increases subsea hydraulic system reliability.

The new range complies with the industry-wide trend towards standardization and simplification. Level sensor data output, for example, can now be interfaced with all popular industry data communication standards, including Profibus and CANbus. Furthermore, the same components are incorporated across the series. This enables more effective spare part stocking strategies and higher stock part availability.

The Advanced compensator range, which complements the basic, heavy-duty, and ultra-long lifetime compensator ranges, underwent extensive durability tests under a variety of conditions, such as extreme temperatures ranging from -20°C to 70°C. Moreover, subsea compensators from the Advanced series have recently been applied in various custom-made ROV projects and have reached TRL level 9.
