Welding Automation Solutions for Offshore PEMA welding automation for offshore wind tower and foundation manufacturing Read More Contact Us Pemamek provides welding automation solutions for the wind energy sector. PEMA solutions are designed for the effective manufacturing of heavy steel structures for towers and foundations. All lines are modular and designed to match the customer’s production capacity needs. Welding automation solutions for the wind energy sector Adaptive robotized welding. Welding Automation for Foundations A jacket structure has a much more complex geometry than a monopile foundation. Essentially, a jacket consists of three or four legs diagonally and horizontally braced against a transition piece in the center. The legs are also interconnected with bracing to provide the stiffness required. High Level of Automation The share of the cost of the foundation relative to the complete wind turbine installation is considerably higher than with onshore foundations. It is extremely important to optimize every part of the foundation production flow to minimize all associated costs. PEMA offshore foundation manufacturing lines are always specially engineered for the manufactured foundation type, ensuring the highest reasonable automation level. Therefore, the productivity and quality produced by the PEMA solution are superior to that of other manufacturing lines. Robotised node welding station for jackets Automatization of node welding is one possibility to increase efficiency in jacket production. Demanding weld shapes can be handled with parametrized robot programming and laser-based seam tracking. Production lines for jacket legs and piles Jacket legs and piles are made from relatively thick material but have smaller diameters than other offshore foundation structures. PEMA has specialized solutions with submerged arc welding. “We highly value our close cooperation with Pemamek. It is difficult to imagine what it would be like, to work without PEMA.” Mr. Roberto Padula, Manager of Operations, TEN Plate prefabrication Short edge cutting 1st side cutting 2nd side milling Flip over plates 2nd side welding Plate Fabrication Blasting and cutting of plates As the size of wind turbines grow, the diameters and thickness requirements for monopile and transition pieces increase. The production line can be delivered as a turnkey package including several demanding processes such as prefabrication, cutting and stable conveyor transportation. Section Fabrication Integrated solutions for efficient section fabrication Specially designed solutions for section manufacturing ensure efficiency and quality throughout the production line. PEMA solutions cover all welding and material handling needs during these phases. Solutions can be used for monopile, transition piece, tripod, and quadripod sub-assembly production, but also to full-length monopile joining. PEMA Welding platform (WS) PEMA WS welding platform is a solution for welding multiple joints simultaneously. This method makes it possible to manufacture even the heaviest offshore structures in reasonable time frames. The platform can be made double-sided to serve two lines and it can replace 2–6 columns and boom type welding machines. Edge preparation is milled after the interior welding is completed. Integrated milling ensures defect-free welding and the possibility to produce semi-narrow gap joints. When welding heavy thick wall material, semi-narrow gap joints can radically reduce the amount of time needed and consumables used. Integrated circular milling • Improved quality • Faster operation • Space efficiency • Semi-narrow gap joints PEMA Flange Fitting One of the latest PEMA innovations, Horizontal Flange Fitting station (PEMA HFF), enables fast, safe and accurate fit-up of the flange to the shell. The flange is placed in a horizontal position while the shell is firmly supported by the anti-creep roller beds. Shell Fabrication Efficiency and quality through correct production line Pemamek provides shell fabrication solutions for all kinds of tubular and conical shells. Long seams varying from the biggest monopile diameters to the smaller diameter and heavy conical jacket leg parts can be welded efficiently in the correctly selected welding solution. Monopile type of foundations includes two heavyweight sections, monopile itself and transition piece that connects pile to turbine tower. In order to first build and then join these huge sections together, you can either use a single can process or utilize substations for joining multiple cans. Whatever process is chosen, Pemamek has the equipment to carry it out. Pemamek’s range of solutions includes welding stations, for internal and external longitudinal and circumferential welding. The productivity of external welding can be further improved by employing PEMA WS welding platforms for the simultaneous welding of multiple or more joints.
