Abstract
The present techniques are directed to systems and a method for reducing trenching around piles. An exemplary method includes attaching a mooring line to one end of a padeye extender bar that is coupled by another end to a padeye on the pile. The pile is installed in a sediment layer. The padeye extender bar is deployed to hold an attachment point for the mooring line above the sedimenlt layer.
Claims18
A system for reducing trenching, comprising:
- a pile configured to be disposed in a sediment layer and held in place by friction with the sediment layer;
- a padeye mounted to the pile;
- a padeye extender bar coupled to the padeye at one end, and attached to a mooring line at an opposite end, wherein the padeye extender bar is configured to support the mooring line above a surface of the sediment layer;
- and
- a stop mounted proximate to the padeye configured to hold the padeye extender bar at an operational position.
