SHIELD your subsea assets

 

 

Subsea assets use different types of identification markers to assist divers and ROV’s to complete their tasks safely. Certain areas of oilfield equipment are more susceptible to damage than others, so what solution is there to protect the signage housed within a high intervention area?

After working on over 800 projects, we like to bring to market what we have learned, and that’s bullet proof…literally. Our Shield™ design uses rigid polycarbonate frames to house and protect our Aquasign® subsea markers. Polycarbonate is used to create bullet proof glass, automotive components and shatterproof windows due to its impact and temperature resistance, so when we say we offer a Shield™, we mean it.

Shield™ is one of our patented subsea marker fixing methods: the design uses a made to measure polycarbonate frame and a watertight seal of Biohesive®225 to make a shatterproof subsea marker. Watch our short video of the Biohesive®225 seal being applied to a custom-made Shield™ marker.

Cable ties, magnets, spring clips and self-adhesive Shield™ markers are just a few of the fixing methods for topside and retrofit application, but what are the bottom-line benefits that Shield™ can bring to your next oilfield project?

  1. Protection in high intervention areas

As mentioned before, certain areas of subsea equipment may be more susceptible to damage than others. Some examples are:

  • Trawler and fishing nets dragging across equipment
  • Anchor snags from passing vessels
  • ROV’s landing on manifold roof’s
  • ROV arms striking surfaces
  • Dropped objects such as coiled tubing reel from a vessel

The above can all damage subsea equipment in different ways, from chipping paint to denting and warping a structure. These occurrences can also happen as part of routine subsea inspection and maintenance. Shield™ is the robust offshore signage solution which resists damage from such subsea activity –  below we speak about high intervention areas and the suitable marking solution for these.

The grated roof on top of the manifold is often where identification markers are attached to. Identification markers are used to display the name of the subsea structure and its supporting equipment, meaning this marker is crucial to subsea operations and must be clearly readable on approach for accuracy, to minimise delays and the amount of time spent underwater.

 

Valves are also a hive of activity. There can be numerous valves on a subsea tree and dependant on their design there is often limited space to attach markers to. These valves are likely to be inspected frequently by robust ROV arms and divers, and their positioning markers, ‘open’ or ‘closed’, must be easily read and undamaged for safety reasons. The Shield™ underwater sign was invented to overcome damage from subsea operations with its robust polycarbonate frame In point 3 we speak about ‘solid as a rock’ Shield™ tags.

  1. Removes the requirement of additional welding

Many operators are conscious of safety and marker integrity and ask for their subsea signs to be protected within a welded frame: this frame is welded into the equipment and is an extra design task for contractors. See an example of this to the right.

Shield™ markers offer the same protection of this frame – after all, polycarbonate is bulletproof – reducing fabrication time.

Shield™ markers can be bolted or bonded directly onto panels or attached to grated surfaces using cable-ties.

Watch our Shield™ installation video to see how easy this product is to install without the need for welding.

 

  1. Provides a marker solution in problem areas

Identification of equipment can sometimes be problematic; i.e. space limitations, difficult substrates, Shield’s™ versatility ensures there is a robust solution for all applications

  • Shield™ can be designed in the form of tags to hang off equipment for when space is an issue g. valve marker tagsSHIELD Subsea Markers
  • Shield™ can be cable tied to grated surfacesg. manifold roofs
  • Shield™ can be bolted or cable tied if an adhesive is not compatible

At AQUASIGN our goal is to make our products easy to use;. Installation guides and videos can be accessed in here after a one-time registration, and these offer insights into what is the best marker design for your project.

  1. Bespoke Retrofit Designs

Shield™ also has another strength – the design is so versatile it can be added both topside and subsea.

Our Retrofit range is strengthened by Shield™ being a trailblazer for adding subsea markers retrospectively. The big benefit is that both divers and ROV’s can fit Shield™ markers with ease, without damaging the marker.

Shield™ retrofit markers can be designed with rare earth magnets and the polycarbonate Shield™ frame can be created with handles and anchor points to make it easier for divers and ROV’s to grip and install. These specialised underwater magnets, which have a holding force in excess of 100lbs, can be designed to bespoke requirements to ensure the best adhesion.

Shield™ also has a retrofit solution for tubulars such as pipelines, umbilical’s, flowlines and risers.  The Shield™ Aquasign® marker can be attached to a spring clip specific to pipe diameters: ROV’s and divers simply push the clip over a tubular and fix into place.

It’s safe to say that we aren’t shielding our customers from easy to use solutions….

  1. Patented and tested

Shield™ has been tested by third parties to ensure its performance in the harsh environments that exist in the offshore industry. Pressure, vibration, slam loading, and environmental tests were performed on Shield™ with no deformation or de-lamination reported. It’s safe to say Shield™ can fight off what the oilfield throws at it.

The summary test report can be found in the download area of our Client Portal.

When we say we have a Shield™ from offshore challenges we mean it. Contact us today to discuss what challenges you face in oilfield operations, and we can try our best to resolve it. Contact us for more information or to arrange a quote.
