SEABED SCOUR CONTROL SYSTEM

SERS Group is the exclusive agent for Seabed Scour Control Systems Limited (SSCS) and their Frond Mat Product range for Singapore, The Philippines, Vietnam, Hong Kong and China.

Seabed Scour Control Systems Limited (SSCS) was established in the UK in 1984 to provide Frond Scour Protection Systems and Services to the Offshore Subsea Oil and Gas Industry. SSCS Frond Mats have been used extensively by and major Offshore Oil and Gas companies since 1986.

The Frond concept also included the use of the Frond Systems in other industry sectors including marine near-shore and inshore civil, Submarine Power and Telecommunications Cables, the Environmental Sector and more recently the Renewables Energy Sector. The SSCS Frond Systems are now also used globally to protect Offshore Wind Farm Installations.

THE SCOUR

Fixed subsea installation will disrupt tidal flow, causing the current to first decelerate in advance of it then accelerate beyond it, to form vortices and eddies which cause sediment to be scoured. In the case of pipelines, cables and umbilicals, beneath them, to cause free spanning.

THE FROND SYSTEM

THE BENEFITS OF THE FROND SYSTEM

The SSCS Frond System comprises continuous lines of overlapping buoyant polypropylene fronds that when activated create a viscous drag barrier that significantly reduces current velocity. The action of reducing current velocity immediately prevents seabed sediment in the immediate area of the fronds from being transported i.e. ‘scoured out’, and causes sediment transported across the fronded area to fall into, and collect, within the fronds.

By reducing current flow the SSCS Frond Systems prevent scour from occurring and rectify scour by reversing the effects that cause it.

A planned and selective deployment of the Frond Systems will immediately prevent and remedy scour, and provide permanent scour protection.

The Benefit of the Frond System are

Eliminates scour immediately upon installation
Provides a permanent, maintenance free solution to scour
Provides dropped object and impact protection
Provides low-cost solution with relative ease and speed
Are environmentally approved

SSCS has received the full approval for the use and deployment of its Frond Systems from:
