Subsea Tensioners

Introducing our range of Subsea Tensioners, specially designed to meet the demanding requirements of divers operating in harsh subsea environments. These tensioners incorporate advanced features to reduce diver fatigue, improve safety, and enhance productivity.

Key Features:

• Combined Body and Bridge: Ensures a robust and integrated structure for reliable operation.
• Lifting Eye Bolt: Facilitates easy handling and deployment underwater.
• 30mm Piston Stroke: Provides ample movement for effective tensioning.
• High Operating Pressure: Capable of operating at 1500 bar, suitable for high-stress applications.
• Twin Hydraulic Connections: Allows for efficient hydraulic fluid management.
• Maximum Piston Stroke Indicator: Ensures precision in tensioning operations.
• Split Reaction Nuts: Designed to reduce diver fatigue and improve efficiency.
• Water Fluid Operation: Compatible with underwater environments.
• Automatic Piston Return: Enhances the ease of use and operational efficiency.
