Publication number: 20110299938Abstract: The invention relates to a method of installing foundation elements, in particular (mono)piles (2), in an underwater ground formation (3), by means of a driver (4), comprising the steps of placing a foundation element (2) on the underwater ground formation (3) and holding the foundation element (2) in place by means of a gripper (10) mounted on a surface vessel, placing a sleeve (6) for reducing noise input from the driver (4) about the foundation element (2), disengaging the gripper (10), lowering the sleeve (6) onto the ground formation (3), and placing the driver (4) on top of the foundation element (2). The sleeve (6) is held at least laterally with a guide (11) mounted on the surface vessel, at least when disengaging the gripper (10).Type: ApplicationFiled: June 8, 2011Publication date: December 8, 2011Applicant: IHC Holland IE B.V.Inventors: Boudewijn Casper Jung, Jan Albert Westerbeek

Patent number: 8033756Abstract: 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.Type: GrantFiled: May 18, 2009Date of Patent: October 11, 2011Inventor: James E.

Patent number: 8016521Abstract: A method for deploying a deepwater mooring spread from a floating vessel with a bow, stern, hull, deck, and aft crane secured to a port side or a starboard side of the hull having a hold, and a fore crane secured to the port side or starboard side of the hull. To lower heavy suction piles or other structures to almost unlimited water depths, the crane tackle after a depth of approximately 1000 meters is replaced using the polymer lines as a temporary lifting pennant with almost neutral buoyancy and therefore no extra weight is added to the lifting tackle of the crane.Type: GrantFiled: January 22, 2009Date of Patent: September 13, 2011Assignee: Kahn Offshore, B.V.Inventor: Richard L.

Publication number: 20110135400Abstract: A support structure for an offshore device and a method of assembling and installing the support structure, is provided including a vertical guide sleeve having, three elongated guide sleeves positioned around the vertical guide sleeve, and various braces connecting the elongated sleeves and the vertical guide sleeve. The support structure also includes a transition joint including a cylindrical portion for connection to an offshore device, such as a support tower of a wind turbine assembly, and a convex portion connected to the vertical guide sleeve. The transition joint may include a strengthening material in contact with an inner surface. The vertical sleeve, elongated sleeves, braces, and transition joint can be assembled onshore with lower piles installed in the elongated sleeves, this guide portion of the structure transported to the offshore location, and then piles driven to secure the structure to the floor of a body of water.Type: ApplicationFiled: June 9, 2010Publication date: June 9, 2011Applicant: KEYSTONE ENGINEERING INC.Inventor: Rudolph A.
