Mooring Remediation

Maximise the Life of Your Moorings with Moorsure’s Mooring Remediation Solutions

At Moorsure, we specialise in assessing, remediating, and extending the life of permanent moorings across a wide range of applications—including FPSOs, CALM buoys, aquaculture pens, and renewable energy moorings. Our expert team ensures your assets remain secure and productive for longer, maximizing efficiency and reducing lifecycle costs.

Why focus on fixing moorings?

Mooring systems for O&G, from CALM buoys to FPSOs, are supplied with the floating asset and their management is often handed over to the field owner rather than being managed by the moorings OEM. We have extensive experience in not just fixing mooring systems, but also as designers of mooring systems, so we understand how they work and how to extend their life.

 

Moorsure can design and supply replacements, remediate the mechanisms causing damage, and extend the life of your assets. We have successfully kept facilities operating even in degraded states. Offshore remediation is challenging as existing assets are already in the field, but Moorsure has the experience to implement novel solutions with offshore contractors.

Our Offerings

  • Failure Assessments

    Evaluate the failure mechanism and remaining life of the asset.

  • Design

    Create designs to remediate failure mechanisms and replace components within the current design's bounds.

  • Case to Operate Documentation

    Provide "case to operate" documents and analysis to keep the facility operating in a degraded state.

  • Supply and Logistics

    Design and supply components with expedited delivery and full logistics support.

  • Installation

    Offer ongoing integrity support, understanding the job isn’t done just because the system is installed.

  • Ongoing Support

    Provide ongoing integrity support, understanding the job isn't done just because the system is installed.

Beyond Immediate Fixes: Life Extension

While immediate fixes are crucial when things go wrong, we also focus on extending the design life of facilities. For moorings, issues fall into two categories:

 

  1. Remaining Strength: Loss of material (corrosion, wear, etc.) reduces the system’s capacity to survive design storms.
  2. Residual Fatigue Life: Accumulated fatigue damage (often in the chain) may lead to failure due to repeated loading cycles from environmental factors.

With a wealth of experience in achieving Class approval for life extension, Moorsure ensures your mooring systems remain robust and reliable.

Artificial Reefs

Artificial Reefs

Through their partner company AMOG Consulting, Moorsure has developed a new artificial reef offering to the market which delivers similar capability to other offerings, but is cheaper and easier to install.

The individual reef units are in essence a reinforced concrete cylinder;

– 4.5 m in diameter

– 6 m in height

– 82.1 m3 internal volume (allowing for 0.5 m settlement into the seabed)

– Weighing 10 tonnes in air, 5.9 tonnes in seawater

– Containing 4.3 m3 TSMR concrete in the main cylinder

– With an additional semi-hemispherical cavern module free standing in the base, installed concurrently with the main cylinder

 

This cylinder is cast with a complex of voids to enable fluid flow into and out of the unit, creating turbulence at the many edges, and, by virtue of blockage and natural chimney effect, current flow up through the centre of the unit.

It will be formed leveraging a departure from the conventional concrete precasting techniques enabled by the use of advanced reinforcing technologies. This departure allows more organic complex shapes to be created in a cost effective manner, by local contractors, with the minimum of materials. It also enables the life of the unit to be that of the concrete itself, with no concerns of spalling through corrosion of internal steel reinforcement.

Each unit will be individual and unique. Its complex of voids and vertical surface more varied like the natural structures it seeks to imitate. Some units will have more voids to give complex vertical relief. Other units will have smaller voids, giving shelter, increased upwelling and protection.

XGR

EXTERNAL GROUT REPAIR SYSTEM

The XGR System (formerly known as the X-Piles System) is used for the repair of degraded piles in the marine environment, including:

– Steel closed section piles

– Concrete piles, square piles, round or polygonal sections

– Timber piles

The XGR System is a complete structural repair system that allows the original strength of the pile to be fully or partially restored (depending on your requirements) and provides protection against post-installation damage. This repair technology relies upon transmitting the load from the sound parts of a pile (or riser) into an external steel tubular sleeve. The steel sleeve is fitted around the region of the of the pile, and a specially designed cementitious grout mix is injected into the void between the steel sleeve and the pile. This grout provides a highly alkaline environment and inhibits further corrosion of the surface of the pile.

Ideally suited for restoring or enhancing the strength of piles, the XGR System, can also serve to significantly extend the useful service life of marine piles and risers in terms of improved fatigue endurance, as well as restoring loss of load bearing material area (from impact, corrosion, spalling, or borers).

Originally designed for steel piles weakened by corrosion or damage from vessel impact, or fatigue degradation (such as Vortex-Induced Vibration (VIV)), adaptions of this technology also enable its use to be extended to coastal and offshore maritime structures such as conductors, caissons, and risers.
