PERFORMANCE OF EMBEDDED ANCHOR CHAINS AND CONSEQUENCES FOR ANCHOR DESIGN

With the growth in popularity of floating systems for offshore oil production, there has been an increased focus on the design of permanent mooring systems. It is widely acknowledged that the anchor chain plays an important part in the total mooring system by developing frictional load and introducing an inclination of the load at the sub-seabed of anchorage. By making a simple and valid assumption, the force equilibrium equations of the chain are simplified to produce closed form expressions for both the force distribution and shows how these equations can be applied to simplify the design of anchor piles and drag anchors.
