Structures
Our bespoke Concrete structures are designed to prevent these subsea impacts, and to keep your business running smoothly. A combination of patented designs and high-quality construction, gives you reliability and peace of mind.
We create the structures to your specification or, if you prefer, use our expertise and experience to advise you on the best design for your installation site. Either way, every structure is tailored to the specific conditions of the site, ensuring that each installation is securely protected. Our Impact Protection Covers are designed to resist the dynamic effects of striking objects by absorption and compliance. Designed to comply with the relevant BS EN concrete codes and DnV Rules, these are normally designed as gravity-based structures which need no additional foundations, meaning they are easy to install. Our pipeline supports to protect your pipeline on their journey across the seabed. We construct sleepers, bridges and rigid bearing units that support and safeguard.
Impact Protection Covers
Designed to client specification or to our recommendations, the parameters of the weight, size and clearances required together with a correctly specified durable concrete mix are incorporated to provide an effective, functional and durable structure.
We offer the option of either standard wire rigging or in house supplied installation equipment for quick release by ROV, diver or remote operations.
Concrete Sleepers
Also known as T-Beams Pipeshield have designed and manufactured a large number of sleepers for some of the world’s Oil & Gas majors.
These reinforced concrete structures can vary significantly in size and can be manufactured with various lifting configurations.
We can also fit neoprene or commercial rubber, ROV handles, beacon holders and transducers and apply customer specific paint markings and coatings.
Concrete Bridges
These are quite literally bridges enabling cables and/or pipelines to cross each other, providing both protection and stabilisation. Designed in-house or to client’s specification, the bridges are gravity based and therefore require no additional subsea fixing once deployed.
Additional features include specialist lifting points that work in conjunction with our lifting equipment. We can also mark the bridges to our clients paint specifications and apply additional coatings where required.
Turning Bollards
Pipeshield can manufacture turning bollards in both concrete and fabric formwork. Often used as umbilical turning bollards.
We have manufactured a number of bespoke turning bollards globally, and can design and build to achieve the required size and weight to suit the subsea environment.
Clump Weights & Anchor Blocks
Used to provide stabilisation for a number of applications including pipelines, cables, outfalls, chains, buoys these custom made structures are used in many sectors including renewables and marine civils.
As with all of our concrete products these can be supplied with fronded systems or anti-abrasive geotextile if required.
All items are engineered with lifting points and can be load tested as required.
Weight Collars
These weighted collars are manufactured to suit your specified diameter pipeline or cable, providing stability and protection.
Often used within marine civils we can manufacture collars pre-fitted with neoprene or commercial rubber if anti-abrasive protection is required. We can also manufacture with a variety of lifting methods including fixed lifters or removable socket lifters.
Horse Shoes
Sometimes used in conjunction with weighted collars, these reinforced concrete structures are often used in marine civils projects to provide stability to pipelines and outfalls.
Engineered to include lifting points, the horse shoes can be manufactured to your specified weight and dimensions. Neoprene or commercial rubber can be pre-fixed and paint or coatings applied as required.
Specialist Structures
Since 1999 Pipeshield have been providing specialist subsea solutions across multiple sectors around the world. Every now and again our projects require specialist ‘one-offs’.
Designed in house by our technical design team we have manufactured many of these solutions for some of the world’s largest oil and gas fields.
These structures can included features such as the fixing or neoprene or commercial rubber, ROV handles, beacons, transducers, specialist coatings and bespoke frond systems.
Please contact our technical design team to discuss your project and let us help you to find a solution.
