PP TECHNIQ - SETTING A NEW INDUSTRY STANDARD IN BLADE ACCESS

PP Techniq A/S is a company that specializes in technical solutions for blade repair and maintenance in the wind industry. Wind turbine blades can be damaged or degraded by several factors including sand, ice, rain, sun, and lightning striking the moving blade and have serious adverse effects on its leading edge and structure. PP Techniq set out to set a new standard for blade access platforms and become a preferred solution in the blade repair market, both onshore and offshore. The platform needed to ensure minimum assembly time on site while still being flexible and without compromising safety for the crew working on the platform. To design this platform, PP Technique needed an engineering partner with extensive experience in the wind industry.

Challenges

To achieve the goal of designing a new blade access platform within 6 months, DIS/CREADIS had to overcome several challenges. They needed to create a product that was flexible, safe, and easy to assemble on site. The platform also had to be designed to seamlessly reach more than 16 meters (52.5 feet) from the tower while changing shape according to the blade geometry and allowing technicians to perform safe and high-quality blade repairs from root to tip on most blades.

Solution

To overcome the challenges, DIS/CREADIS created a team of 13 engineers with specialized competencies in structural calculations, mechanical design, electrical design, functional safety, and project management. Each resource was handpicked to create the right solution for the customer. Together, PP Techniq and DIS/CREADIS prepared a clear product requirement specification and defined the scope of work. The project was executed from a DIS/CREADIS project hotel, where PP Techniq worked several times a week. The presence secured regular interaction between the teams which ensured the optimal solutions for the new platform design.

The team was able to meet the customer requirements and design a product that partly utilizes off-the-shelf technologies, solutions, and mechanisms seen in other industries but custom designed to fit the purpose and keep the overall weight and cost low. The result was ‘SQYFlex’, a unique tower-guided blade access platform, which is designed to seamlessly reach more than 16 meters (52.5 feet) from the tower while changing shape according to the blade geometry and allowing technicians to perform safe and high-quality blade repairs from root to tip on most blades. The platform has a rated payload of a record high 550 kg and is equipped with three hoists, which ensures it is the best solution in the market.

Why DIS/CREADIS

DIS/CREADIS was able to deliver a unique solution to PP Techniq A/S because of their strong mix of competencies and project management skills. They were able to create a team that could overcome the challenges presented and deliver a product that met the customer requirements. By having PP Techniq present with the DIS/CREADIS project team, they were able to ensure regular interaction between the teams, which ensured the optimal solutions for the new platform design.

OVERCOMING WIND TURBINE COMPONENT AS-BUILT DATA LIMITATIONS WITH SITE SCAN AND 3D CAD MODELS

The wind industry is no exception to the multiple handoffs of service contracts that can occur between Original Equipment Manufacturers (OEMs). One of our customers needed to develop a major component exchange procedure and maintenance documentation for an expired service contract of a wind turbine that had been taken over from one OEM by another. However, the customer faced limited access to as-built data, making this task challenging.

STIESDAL - GROUNDBREAKING FLOATING WIND TURBINE FOUNDATION DESIGNED TO BE COST EFFECTIVE, EASILY ASSEMBLED, AND SCALABLE

Renewable energy is poised to take center stage around the globe with wind generated power as one of its main sources. Until recently, wind farm projects have been limited to locations that are either onshore or in the shallow waters of the North Sea, the Chinese coastlines, and Eastern coast of the United States. Stiesdal, Shell, RWE, and TEPCO have partnered on the TetraSpar Demonstration Project to solve this problem and allow for wind generating turbines (WTGs) to be floated in deeper waters around the world. The TetraSpar Demonstration Project is a floating wind turbine prototype that is operational at the Marine Energy Test Centre (METcentre) near Stavanger, Norway.

PP Techniq - Strength in collaboration - discreadis helps ensure anchor point safety

PP Techniq A/S specializes in providing technical solutions for wind turbine blade repair and maintenance. They offer advanced blade access platforms which are safe, flexible, and easy to operate. The SQYFlex™ is their newly developed blade access platform. The platform can be raised up and down and adapts to the shape of the blade giving full access and alleviating the need to remove the blade for service. PP Techniq recently implemented an anchor point on their service platform, allowing them to replace personnel, equipment, and materials on the platform while it is attached to the wind turbine blade. This solution saves time by avoiding the process of lowering the platform down to the base and returning it to the blade when replacing personnel.
