MEYGEN – ENGINEERING EXCELLENCE ENGINEERING SUCCESS


We introduce Parker Hannifin a Fortune 250 global leader in motion and control technologies. For 100 years the company has engineered the success of its customers in the mobile, industrial and aerospace markets.


They now bring that engineering expertise to the ocean power market. We hope you enjoy reading about a specific tidal turbine and its foreseen benefits to the industry.


THE ATLANTIS TIDAL TURBINE AR1500


The ocean power market and specifically the tidal energy market segment is one of the the most promising emerging renewable energy segments and in contradiction to the leading and more well-known renewable energy sources of wind and solar power, tidal power has the quality of widespread predictability!


VARYING ENERGY TECHNOLOGIES


An unusual aspect of ocean energy is the approach of the market’s technology developers to capture the power of the ocean – there is not, as yet, a standard approach as we see in mainstream wind and solar industries. Some technology developers are aiming to convert wave motion into electrical power and connect to the grid, where others are looking to supply off-grid smaller amounts of electrical power. Yet more are using the water’s movement to pump water back to shore for water processing purposes (reverse osmosis for drinking water). The tidal segment of the ocean power industry, because of its predictability, is ideal to provide electrical power to the grid. However even here we see numerous approaches and device designs being utilised to accomplish this.


COMMON FACTORS


Three common factors are: the need for financial investment, the massive dedication by the technology developers needed to bring the technology to prototype phase and the milestone of launching a full scale device into the water.


PAGE 20


This milestone is now imminent with the launch one of the industry’s leading technology developers with their latest tidal turbine, the Atlantis Resource’s AR1500 tidal turbine!


The AR1500 turbine is a 3 bladed, seabed mounted device with a rated capacity of 1.5MW at 3.0 m/s tidal flow. It is designed to withstand the extreme environmental conditions expected in the Pentland Firth in Scotland and the Bay of Fundy in Canada.


TURBINE FEATURES


This turbine exhibits best in class design, with features such as…


• Variable pitch rotor blades for maximum energy capture


• Integrated gearbox and bearing- less permanent magnet generator


• Fast deployment and connection system; nacelle deployment less than 90 minutes


• 360 degree yaw capacity and survival lock system


• Multiple, fully redundant electrical systems for long term subsea operation


LOCKHEED MARTIN MULTI-COMPETENCE TEAM


Lockheed Martin Corporation completed the detailed design of this cutting edge turbine in the USA. The corporation is an investor of Atlantis Resources, who have a design and build contract for the yaw drive, the variable pitch system, the manufacture of the steel turbine housing and the assembly of all the turbine modules (including the gearbox and generator). The contract also includes the systems integration and quality assurance of the overall turbine delivery programme. The current scope of the contract is an extension of the original contract dating back to 2013.

Forming a multi-competence team spreading over the Atlantic, Lockheed initially worked with Parker’s Hydraulic Sales Engineer for north east region of the United States, Dave Hamby, to specify the correct hydraulic products for the variable pitch rotor blade system. This system is one of the turbine’s most essential systems as the blade pitch angle not only controls the speed of the turbine’s rotation (energy capture) but also functions as the primary brake.


In conjunction with the design and build of the variable pitch system, the yaw drive and the lubrication oil filtration system on the gearbox, Lockheed reached out to industry leader in the motion and control space, Parker Hannifin.


PARKER HANNIFIN – PROJECT CONTRIBUTION


Although typically not direct financial investors into the technology developers of the tidal energy capture devices, all supply chain companies involved in tidal projects make a significant investment in respect of time and resources. They accept the risk of device/project


failure, in order to assure the right products are chosen and implemented that allow maximum performance and ultimately to secure future sales.


INVESTMENT


Parker have been investing in the wave & tidal industry for many years and have built or supplied product for many of the devices on sea trials. Atlantis, who have already seen successful sea trials with their previous tidal turbine are a natural candidate for Parker to support and supply components and systems.
