Driven Jacket Piles Installed in Weak Triassic Rock in the North Sea
Driven Jacket Piles Installed in Weak Triassic Rock in the North Sea
There is currently a dearth of published literature regarding the installation prediction of driven piles in weak rock. This is predominantly due to the lack of available installation records in the public domain along with the relatively limited research into understanding the Static Resistance to Driving (SRD) during pile driving into these materials. As offshore wind expands globally, it is likely that more sites will be developed in areas where shallow rock is present. Therefore, to ensure optimal design decisions and thorough risk assessment can be made, it is critically important that the installation of driven piles in these materials is better understood. This paper presents a case study where driven jacket piles were installed into weak Triassic rock. Pile driving records were acquired during the installation and back analysis of this data has been performed to compare the performance of various SRD methods.
