Abstract: A protection assembly for mounting in an underwater support structure includes at least one bend protection device coupled to a retaining device so that together they provide a through-going passage for receiving an elongate member which is to be protected. The elongate member passes through a support structure opening, and the retaining device is configured to be received in the support structure opening and to engage with the support structure to resist subsequent withdrawal from it. Installation of the protection assembly includes grasping the protection assembly with a releasable clamp, arranging a pulling line to pass through the support structure opening to the mechanical clamp and securing the pulling line to the mechanical clamp, drawing the retaining device of the protection assembly into the support structure opening using the pulling line and engaging the retaining device with the support structure, and releasing the clamp from the protection assembly.

Abstract: An assembly (10) protects an elongate member (e.g., an electrical cable) extending through an opening in a support structure (e.g., a wind turbine leg (12) and passes through at least one bend protector, e.g., a bend stiffener (20a, 20b), and a retaining device (18). The retaining device (18) has a body configured to lock itself to the opening. The body carries an abutment (78) and locking members (84), which are movable between retracted and extended positions. A movable member (86) is carried by the body (82), moveable axially with respect to it, and attachable to a pulling line. As the assembly (10) is pulled into the opening by the pulling line, the abutment (78) engages the support structure and arrests inward movement. The movable member (86) is moved in the inward direction with respect to the body (82), and the locking members (84) move to their extended positions to lock the retaining device in place.

Abstract: The invention relates to a protection assembly for mounting in an underwater support structure, and to a method of installing such an assembly. According to one aspect of the invention, the protection assembly comprises at least one bend protection device (20a, 20b) coupled to a retaining device (18). The bend protection device (20a, 20b, 26) and the retaining device (18) together provide a through-going passage (32) for receiving an elongate member which is to be protected. The support structure (12) has an opening (16) through which the elongate member is passed, and the retaining device (18) is configured to be received in the opening (16) in the support structure and to engage with the support structure to resist subsequent withdrawal from it.

Abstract: The present application further describes a method for extending the operating life of a tip shrouded turbine blade that includes the steps of: 1) removing an end located cutter tooth from a seal rail of a tip shroud, the end located cutter tooth including a cutter tooth located at the end of one of the suction side and pressure side of the seal rail of the tip shroud; and 2) attaching a center located cutter tooth to the seal rail of the tip shroud, the center located cutter tooth including a cutter tooth that is located in the approximate center of the seal rail of the tip shroud. In such method, the center located cutter tooth may be attached to the seal rail such that the center located cutter tooth is inside the airfoil if it were projected radially outward from the narrowest point below a tip shroud fillet.

Abstract: A bucket for a turbine is described. The bucket includes a dovetail portion configured to couple the bucket to a turbine wheel, the dovetail portion having a lower surface. The bucket also includes a shank portion that extends from the dovetail portion and an airfoil having a root and a tip portion, an airfoil shape, and a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in Table I. The bucket also includes a plurality of cooling passages. The plurality includes no more than five cooling passages that extend between the root and the tip portion of the airfoil. Each of the cooling passages exits the airfoil at the tip portion, the plurality of cooling passages are positioned in a camber line pattern.
