Energy from tidal and wave sources is a dynamic and emerging and industry that places demands on Developers and Operators to get facilities tested and producing power quickly. Fundamentally, interfacing and engineering integration of their facilities is crucial to success. ABMAS, an EPC provider with its proven capability and expertise helps Operators and Developers to achieve this.
Wave and tidal energy converters operate in harsh environments often in remote locations. This is a challenge for developers and operators because these devices need facilities and numerous interfaces to make them work. We design and build low cost, field proven solutions that can be fixed, mobile and transportable.
Our designs and systems provide electrical, communications, mechanical, marine and instruments platforms and solutions for the most challenging and arduous operating environments. Often, the best wave and tidal generation sites provide great technical challenges due to the operating environment. What is good for the tidal power is also a technical challenge. We understand and know these challenges. We apply innovative, yet proven designs from our experience from across industries and disciplines. This way the customer gets ingenuous solutions and applications founded on solid technology that give the highest probability of success.
While studies are valuable there comes a time when the tidal generator company wishes to turn their aspirations into tangible integrated systems. This is where ABMAS comes in. We use proven technology to take your concepts from FEED study, to design, build and commissioning. Our solutions are easy to build, designed to be flexible and work in the most difficult conditions. No matter how difficult your operating needs are we can deliver a timely solution with a high chance of success that does not cost the earth.
Our systems are designed to be reused and deployed readily. They can be upgraded, modified or customised easily. Most of all they are built to survive and keep working. ABMAS designs and builds solutions for all interfaces electrical, communications, I.T, mechanical, operational and marine. Skilled ABMAS technical staff can test and commission and give after sales support for our solutions in field with a quick response anywhere in the world. Take a look at our case studies of previous completed solutions.

Tidal energy requires installing large energy converters in fast flowing tidal seas or rivers. These fast tidal currents that are ideal for the energy converters create a challenge to deploying, interfacing and monitoring these devices because divers and remote operated vehicles (ROVs) cannot cope with the high currents. The Client needed a subsea platform to be deployed in high tidal current on a rock sea bed to house a battery of sensory and monitoring equipment some 4 km out to sea. The high currents caused rock projectiles near the seabed. The subsea package had to power the equipment and communicate with the control centre remotely with high reliability, because interventions were difficult.
ABMAS applied its experience from the oil and gas industry to using CAD 3D modelling technology to design and build a large subsea package that became known as ‘The Pod’. It featured an array of monitoring equipment that was carefully mounted to prevent interference and housed in a robust steel and GRP structure to stop damage from tidal projectiles. Every power and communications system had multiple levels of redundancy so there were no single points of failure. The ‘Pod’ included several deployment methods and slotted ballast weights to aid operations.
The ‘Pod’ was built on budget and delivered on time for the arrival of the tidal converter. It continues to operate giving the client a good platform that they can re-use and modify for use in other tidal converter packages.
Our client was required to produce a platform to accept power, monitor, and measure and remotely control from large test wave energy converters under development, whilst working in harsh open seas. The platform was not permitted to physically connect to the shoreline. While there were several theoretical studies this had not been done before so posed a major technical challenge. Also, the platform had to be in position before the deployment of the wave converters so there were time constraints. The structure could not be permanent and had to join with several varieties of wave converter, none of which were completed before the interface platform. The unit had to survive for up to one year at sea without aid.
ABMAS designed, built and commissioned large moored interface buoy that would accept and control the output power from a variety of wave converters, including remote switching. It provided remote SCADA interface telemetry, with accurate monitoring and measurement via several communications systems.
Because this was the first time the concept had to be proved. ABMAS produced a FEED study that resulted in a detailed design and build plan along with a scale 3-D model of the buoy. A combination of electrical power and control wet mate connectors with a flexible interface design overcame the challenge of the variety of wave converters that were likely to be connected for development. All topsides were designed to be removable to give the client maximum usage and reconfiguration options when using the buoy.
Multiple levels of redundancy were designed. This together with several secure supply systems combining traditional sealed battery, solar and fuel cell technology enabled the buoy to survive and operate unaided under various levels of activation, including a deep hibernation mode. Marine classification of the buoy was a challenge because design precedence. ABMAS helped the Client to get the system inspected and approved from DnV.
A second buoy was added to the project. The client was keen to ensure that the buoys did not adversely impact the environment where they were deployed. This consideration was at the forefront of the ABMAS design. For example, no packages needing diesel were used, the paint coating was carefully selected, and even anti-seal railings were used. Survivability in heavy seas was a concern for the client. The topside and marine design allowed for the buoy to function even if damaged. The interface buoys have operated successfully for over two years. They survived some of the biggest storms and sea conditions, whilst continuing to function.
The project was designed and completed in one year and it was under budget. Client comment at the end of the project “To all of ABMAS with sincere thanks – Job well done!”
