How is FLEXMAT™ different from other pipeline stabilisation solutions

FLEXMAT™ gravity anchors offer a more cost-effective alternative compared to traditional methods such as trenching, mechanical anchoring, and rock dumping. These alternative methods are often more expensive and less reliable, with a higher failure rate during extreme sea states.

FLEXMAT™ gravity anchors provide long-term stability to pipelines, pipeline bundles, and piggy-back pipe/umbilical assemblies. They have a proven track record, even in extreme sea conditions, ensuring the longevity and integrity of the pipelines.

FLEXMAT™ anchors and mattresses can be installed quickly and efficiently, without requiring sophisticated installation equipment. The simplicity of the installation process, which often only requires a spreader beam frame, saves time and reduces associated costs.

By utilising FLEXMAT™  gravity anchors, the need for weight coating can be significantly reduced or eliminated. This reduction in weight coating thickness reduces the pipeline's external diameter and peak hydrodynamic forces, resulting in cost savings and improved operational efficiency.

FLEXMAT™ gravity anchors are versatile and adaptable to various pipeline applications. They can be employed for pipeline stabilisations, scour control around structures, impact protection, and as spacers at pipeline or cable crossings. Their effectiveness has been demonstrated in Australian waters and internationally.

Extensive research, development, and testing have validated the stability and performance of FLEXMAT™ gravity anchors. Their track record of successful applications, even in extreme sea states, offers reassurance and peace of mind to pipeline operators.

These unique features distinguish FLEXMAT™ as a superior pipeline stabilisation solution, offering cost savings, durability, ease of installation, and reliability when compared to other available options.

In 2006, Worley Parsons (WP) was tasked with EPCM activities for an iron ore transfer facility near Port Hedland, commissioned by Fortescue Metals Group. Facing the challenge of erosion from waves and currents, WP conducted a thorough analysis and concluded that a 'Flexmat' concrete block mattress lining would be the ideal solution. This choice proved both durable and cost-effective, with a significantly faster installation rate compared to traditional rock linings.

Due to the strong bonding of concrete blocks to the loop mat base layer, maintenance requirements are minimal, unlike rock linings that often require frequent maintenance. The project was conducted in strict compliance with international and Australian Standards, ensuring quality and sustainability.
