Energy absorption systems for floating structure anchoring

When designing floating infrastructure, one of the most critical aspects is the anchoring or mooring system of the structures.

Floating platforms are constantly subjected to dynamic forces generated by:

• wave action
• wind
• currents
• tidal variations
• operational loads

Properly managing these forces is essential to ensure the stability, durability, and safety of the infrastructure.

The importance of energy absorption systems

Mooring systems must not only keep the structure in position but also absorb and dissipate the energy generated by dynamic loads.

To achieve this, various technical solutions are deployed, which may combine:

• elastic elements
• damping systems
• articulated connections
• flexible or rigid mooring configurations

The goal is to prevent the direct transmission of excessive loads to the floating structure and anchoring elements.

Comparison between rigid and flexible systems

Depending on the type of infrastructure and the marine environment, different design approaches can be utilized.

Rigid systems

• greater geometric control
• reduced relative movement
• higher structural demands

Flexible systems

• enhanced energy absorption
• greater adaptability to wave action
• reduced transmission of extreme loads

The proper choice always depends on the specific context of the project: depth, tidal range, seabed type, and wave conditions.

Experience-driven engineering

The design of these systems cannot rely solely on theoretical calculations. Cumulative experience from real-world projects is essential to understanding the long-term behavior of structures.

At MSI, we apply over 30 years of marine engineering expertise to develop site-specific solutions, taking into account both the technical parameters and the operational requirements of each installation.
