Gripper
- The Gripper is a device that temporarily secures the grouted connection between the jacket and pile, preventing quality degradation of grout caused by environmental loads before it achieves full strength.
- By applying Gripper technology, structural stability of the substructure can be ensured even under harsh environmental conditions.
-
Key Functions and Specification
-
- Gripper Capacity & Pile Diameter: The system can be customized to meet client requirements, offering optimal gripper specifications based on the pile diameter.
- Vertical & Horizontal Cylinders: These cylinders secure the jacket inclination and maintain horizontal alignment, effectively controlling relative movement during curing to enhance grout quality and structural stability.
- Gripper Control: A dual control system is provided via a dedicated topside control panel and an emergency subsea ROV panel.
- Standards Compliance: The system is designed to meet the EAC requirements specified in DNV-ST-0126.
