Applications have covered a wide diameter range, from around 0.1 m to 1.1 m. (which was the largest OD application, on Woodside’s Rankin Trunkline at the N.W. Shelf)

The applied anchors have an excellent, failsafe, track record whilst permitting lateral pipeline displacement during extreme sea states. (in accordance with DNV Guidelines)

The ‘streamlined’ profile of the anchor’s cross section renders a large reduction in drag and lift coefficient and, as a consequence, greatly reduces the required supplementary weight that would need to be added to the pipeline, cable or umbilical to ensure its stability under the design wave- and current conditions. This renders a major overall cost saving of at least 50% in a typical average case.

The reduction in overall weight of the pipeline is also important in that it substantially increases its allowable free span and, as a consequence, greatly reduces the risk of buckling failure.

By comparison, alternative methods of stabilisation such as trenching, mechanical anchoring and rock dumping are far more costly and less reliable as evidenced by the substantial failure history of these systems during severe sea states

The mattresses and anchors can be installed at a fast rate without requiring sophisticated installation equipment.

If necessary Marecon’s principal pipeline engineer (P J de Geeter) would be able provide advice based on more than fifty years' experience.
