 The Construction Mat is primarily used for separation,
stabilization, and protection of underwater pipelines in deep and shallow
water. The design of the mats allows for self-silting and proper
separation between the pipelines. The silt-in process aids in the mat's
stability. The Construction Mat is easily installed by a ROV (Remote
Operated Vehicle), diver handling frame or Submar's patented mechanical
handling frame, especially designed for ultra deep-water mattress
deployment. Submar mats can be supplied with patented 'Non-Shielding',
'Non-Abrasive' pads.Articulating concrete mats have been used successfully
in the North Sea for many years. Submar introduced concrete mat technology
to the Gulf of Mexico (Gulf) in 1990. Before that time, pipeline operators
in the Gulf used traditional sand/cement bags for pipeline
crossings. Submar mats have been used very successfully for pipeline
separation, stabilization and protection. Articulated concrete mat
crossings are accepted as the new standard by DOT, MMS, contractors and
pipeline operators. The concrete mat is superior in quality of
construction, costs savings, and worker safety compared to sand/cement bag
technology. Mats can allow access to pipelines, valves or other protected
structures by removing mats used as cover, then replacing the same mats
after maintenance. Recent advances in offshore technology have expanded
the need and utilization of concrete mats. Mats can be placed diverless by
ROV, which allows deepwater deployment. New survey techniques allows
accurate placement at great depths. Submar mats have an indefinite
lifetime in offshore applications.
