Subsea Protection Systems (SPS) products

Concrete mattresses provide a recognised engineering solution for several of the challenges faced in subsea pipeline construction, umbilical deployment and seabed and soil protection/stabilisation. They are cost effective and may be readily deployed using standard handling systems.

Single or multiple reinforced concrete Pipeline Supports are used to provide a crossing for a new pipeline over an existing pipeline, umbilical or other asset on the seabed.

SPS Covers protect pipelines, umbilicals and other subsea assets from dropped objects or trawl board impact without transfer of load to these assets.

SPS Crossing Bridges are an ideal solution for crossing an existing pipeline with an pipeline cable in a single unit installation. SPS can manufacture these to its standard designs, clients own designs or can work with clients to develop and design a Bridge for a particular application. As for all SPS products, due consideration is given to all of the issues around handling, installation and certification.

Grout, Sand or Gravel may be supplies in 25kg sealed bags then packed into 1 tonne certified FIBCmultiple trip bags. Special 1 and 1.5Tonne bags may also be supplied for ROV release subsea. The materials are used for filling voids and general support to the other SPS Products; grout bags will cure after deployment to provide a permanent stable support. Sand and gravel can also be supplied loose in FIBC Bags.

When a solid object, typically a pipeline, offshore platform structure or bridge pier is put in place on a loose sedimentary sea or river bed the flow of water around this under certain conditions can cause erosion of the bed; this is called scour. It may be gradual or rapid but it is cumulative and the end result may be unsafe spans on pipelines or an unsafe structure generally. Natural seaweed reduces water velocity locally and correspondingly reduces scour; the SPS Frond Mattress replicates this natural phenomenon. Over 1000 buoyant fronds per square metre at nominally one metre high are built into the Mattress and properly deployed (either directly onto the seabed or attached to an SPS Fleximat) they will stop scour rapidly.

As set out in the description of its Products, SPS pays due consideration to issues around their handling and deployment and the corresponding certification of handling equipment. SPS can design and supply handling and deployment systems for all of its products, for purchase or hire. Alternatively purpose built frames can be designed for specifc client requirements

SPS we work hard to find the best solutions possible for our customers. In order to improve efficiency during vessel mobilisations and offshore, we have designed and manufactured a range of Concrete Mattress Speedloaders to allow customers to mobilise / deploy multiple Concrete Mattresses in one simple lift rather than multiple individual lifts.

Rock Filter Bags can be used for Scour Protection, Span Correction, Cable Protection & Flowline Protection. The Rock Filter bags are an environmentally friendly solution as these are made from 99% recyled materials. Due to high flexibility of the Rock Filter Bags it is possible to fill spans by using multiple bags. Using SPS handling equipment it is possible to install many Rock Filter Bags at a time.
