Abstract
The present invention relates to a marine pipelaying friction clamp device for frictionally retaining an offshore pipeline having a longitudinal axis, comprising multiple clamping units (). Each clamping unit comprises a friction pad () and an associated force actuator (), and further comprises a base () fixed to the actuator, wherein the friction pad is rotatably connected to the base via a single axis (H, H) hinge mechanism defining a single hinge axis parallel to the longitudinal axis. The single axis hinge mechanism comprises first and second complementary semi-cylindrical hinge surfaces, allowing a rotation of the friction pad about the single hinge axis over 2-20° relative to the base. The friction pad is also axially connected to the base via complementary axial load surfaces () on the base () and on the friction pad ().
