To support its client, IQIP mobilised a range of IQIP equipment, including an S-2000 hammer spread with a Flanged Upending Tool (750t FPUT) and Pile Guiding Tool (PGT). This equipment successfully installed monopiles of over 51m length and 5.5m outside diameter.
Hydrohammer to drive the monopiles
The Hyrohammer S-2000 (2,000 KJ) was used for driving the steel piles into the seabed. Prior to the operations the advisory service IQIP analysed the geotechnical conditions and calculate the most effective, efficient and safe piling procedure and the most suitable equipment for the piling operation.
Flanged Upending Tool
The Flanged Pile Upending tool (750t FPUT) is specially designed to upend and lift large-diameter piles with an integrated flange. This upending tool with a lifting capacity up to 750t makes it possible to raise monopiles efficiently and accurately place the pile in the right position.
Pile Guiding and Positioning Frame
The Pile Guiding and Positioning Frame, also known as Pile Guiding Tool (PGT), has dual functions of up-ending and gripping, and was used for guidance of the foundation piles during upending and for positioning during pile driving. This tool guarantees the accurate positioning of monopile directly on pile position and eliminates any extra transfer and vertical pile movement in order to maximise operational efficiency.
