Bitumen mattresses are used to support and protect pipelines and cables with a cushioned interface to reduce the risk of damage from
sharp edges. Our bitumen mattresses offer good impact resistance and can be used where concrete is considered too abrasive.
They are manufactured from a special blend of mastic contained within an outer canvas sheet with integral lifting systems.
Our bitumen mattresses are bespoke sizes made to order though available in 150mm and 300mm thickness and can be sized to suit
project requirements whilst maintaining a minimum depth to width ratio for integrity.

Our rock mattresses are an effective alternative to a conventional rock dump process. They can be used to protect and
stabilise pipelines and cables as well as levelling uneven seabeds.
Rock mattresses benefit from containment and placement accuracy to prevent rock migration.
Our rock mattresses are manufactured with integral lifting devices compatible with our standing lifting and installation
equipment as well as a fabric centreline to aid with subsea placement.

Our added value products and services complement our precast solutions.
Products include offshore rated bulk-bags and drop bags and either can be
loose filled with sand, aggregate or grout, or be packed with individual 25kg,
40kg, 50kg or bespoke sacks to suit any application. Our individual sacks can
be fitted with handles for ease of placement and security.
Pipeshield also supplies Granular Marine Mastic, well suited for pipeline joint
coating. We can also supply marine mastic in bulk or offshore rated sacks for
in-situ and in-field placement.

We offer both bespoke or standard fabric formworks well suited for
various applications including pipeline support, foundation seals,
void filling etc.
Our standard formworks are available in various heights and base
dimensions to suit pipelines up to 1150mm diameter.
Our formworks are fabricated in the UK to maintain strict QHSE
processes.

Installation Equipment
We design, engineer and manufacture a range of lifting, handling and
installation equipment.
This includes our standard ROV and diver friendly quick-release lifting
frames and beams as well as specialist deployment frames and
enhanced speed-loader arrangements.
We have developed an enhanced speed-loader arrangement
compatible with most of our concrete mattress products. Our speed-
loader negates edge block damage which could impact on the
performance of mattresses and render them unusable.

Scour Studies
Photos from a one year trial by Shell in the southern North Sea showing the formation
of a sediment bank over a Frond System (photos supplied by Shell).
At the previously scoured pipeline a fully developed and compacted sediment bank
has been formed over the buoyant fronds and marine life has colonised the final
bank.
Pipeshield Bi-Flex mattresses with buoyant fibrillated polypropylene fronds (SSCS
supplied) are proven in a full range of scour sensitive environments. Typically fronds
are 1.25m high and provide the capability of sediment banks over 900mm high in 35 -
60 days in good conditions.

The photographs below show the fronds

reinforced sediment back beyond the
mattress edge. After one year, colonised
marine life was noted.
We can provide in-house analysis and bespoke solutions for almost any subsea terrain
and situation. For more specialised work we engage leading UK consultants for
Geotechnical and scour assessment to complement the in house design.
Our services include verified in-house analysis software, bespoke solutions, professional
recognised endorsement and engineering integrity.
We are constantly researching and designing new and innovative products, solutions and
services. We also regularly review lessons learnt and client feedback to consider on-
going improvements to our existing products.
