Development of Alternative Anchor Line Configuration

Currently, production platforms can remain in the same location for up to 30 years. Therefore, it is necessary to invest in better and simpler anchor configurations. The anchoring systems used usually require traction equipment that occupies large spaces on the deck of the platform.

This research consists of defining an anchor line configuration that is equivalent in functionality to the current models, composed of moorings, steel cables and synthetic cables, but that do not require their pre-traction with high loads.

With this, a new anchoring system in deep water depths will be analyzed. To this end, it is proposed to use a weighted anchor line using polyester cables and a weighted anchor line using another type of material.

First, a literature study was carried out on the main anchoring systems currently used. Through it, it was possible to learn about materials that can be used in anchor lines. Thus, it was chosen to analyze two types of materials: polyester and HMPE. This is because polyester is the most widely used material currently in deep-sea anchoring systems. On the other hand, HMPE has greater rigidity than other synthetic materials and has smaller and lighter diameters, promoting technical and operational advantages
