Abstract:
Apparatus (10) for driving a pile into an underwater substrate, comprises a pile guide (11) having a base frame (12) with a guide member (14) mounted thereon, the guide member configured to guide a pile as it is driven into a substrate when the base frame is resting thereon. The base frame (12) defines a substantially rectangular platform (16) for carrying a device for driving a pile into a substrate, and a power supply for supplying power to drive the device, during deployment. Once deployed, a pile (50) is positioned in the guide member (14) and the device (2) is lifted onto the pile (50) . The power supply (30) drives the device (2) as the pile (50) is driven into the substrate.
