Embodiment Construction

[0022] The present invention provides a ramming or beating device that can be used in extremely deep water and methods and systems for using the same. The equipment can be used to drive piles, drive pipes used as deep water well-leaders, and can be used to drive soil sampling devices into subsea soil. Ramping or beating equipment can be used in shallow water and on land, however it is believed to be especially useful in deep water applications.

[0023] Go to attached image and refer to figure 1 , shows a side view of the ramming or beating system 10 of the present invention. The ramming or beating device 12 is connected by a lift line 14 to a water supply vessel 16 such as a boat or barge via a hoist 16a which can be used to lower and raise the ramming device 12 . The lift line 14 passes through a pulley 16b attached to the crane arm 16c. The hammering device 12 is shown in this embodiment as driving a stake 18 into subsea soil S, which may be located several thousand feet...

Abstract

A pile driver is provided for use in deep water with a remotely operated vehicle (ROV) and a working ship for setting piles, pin piles and well conductors in subsea soil and for soil sampling in deep water and can be used for shallow water and land-based applications. A ram mass or hammer is received in an open frame and hydraulically reciprocated while in contact with water. A piston rod received in a piston cylinder is secured at one end to the hammer through a coupling mechanism, and an external source of hydraulic power is used with an on-board hydraulic circuit. Gas is compressed during an up-stroke to store energy, which is released during a down-stroke to push the hammer downwardly. The coupling mechanism provides a connection between the piston rod and the hammer that can move between an essentially rigid lift connection, an essentially rigid downward-push connection and an essentially non-rigid impact connection for preventing buckling of the piston rod when the hammer strikes at its lowermost point. One embodiment of the coupling mechanism includes a hollow body having opposing longitudinal slots, a rod slidably received in the hollow body that is pinned slideably at oneend in the opposing slots and pinned fixedly at the other end to the hammer, with a spring in the hollow body providing a bias to push the rod toward the hammer.

Description

technical field [0001] The present invention relates to pile drivers, and more particularly to tamping apparatus, systems incorporating such tamping apparatus, and methods and uses for driving objects into deep subsurface soil. Background technique [0002] To drive piles, well guides, soil sampling devices, and other objects vertically into the subsea soil, large and heavy surface powered hammering devices exist. Existing thumping devices are extremely large and expensive to deploy, and due to their size and complexity, existing thumping devices tend to be limited to relatively shallow seawater depths and to driving relatively large objects. Existing techniques also include drilling and / or injection holes in the sea floor and then inserting objects into the holes, but these techniques require very large and expensive ships or platforms and considerable time for installing the objects. Furthermore, where piles, well guides and other objects have to remain in the soil, these...
