A composite elastomeric flexible element has an elastomer layer between rigid members. When subjected to loads, and as time goes by, the elastomer layer will undergo damage in the form of micro-voids and polymer chain scission. The time it takes the damage to reach a predetermined, but safe state is a known function of several parameters such as loading rate and load magnitude, time at load, temperature and frequency. The damage decreases the electrical permittivity of the elastomer and changes the electrical conductance of the elastomer if the elastomer is in the environment of an electrically conductive fluid or when the elastomer includes conductive filler. The health of the flexible element is monitored by measuring the electrical impedance of the elastomer layer, computing an indication of health from the electrical impedance and trend data for the elastomer layer, and reporting the indication of health to a human administrator.

ELASTOMERIC SLEEVE-ENABLED TELESCOPIC JOINT FOR A MARINE DRILLING RISER
A telescopic joint for a marine drilling riser has an outer barrel and an inner barrel defining a central lumen for passage of a drill pipe string. The inner barrel is received within the outer barrel, and there is a clearance fit between the barrels for sliding of the inner barrel with respect to the outer barrel while maintaining a coaxial relationship between the barrels. A tubular rolling elastomeric membrane is disposed within the outer barrel and has one end secured to an outer circumference of the inner barrel and another end secured to an inner circumference of the outer barrel for sealing drilling fluid within the central lumen. As the inner barrel slides with respect to the outer barrel, the elastomeric membrane rolls with respect to the inner barrel and the outer barrel so that wear of the seal due to abrasion is eliminated.
For load compensation, different kinds of elastomeric load compensators are placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.

A freestanding hybrid riser system includes a steel pipe riser having a bottom end anchored to a foundation on a seabed through a flexible joint and a diverless pipe connector. A tube is mounted to the foundation and connected to the diverless pipe connector for providing a static connection to a subsea pipeline on the seabed for a flow of fluid between the steel pipe and the subsea pipeline and through the flexible pipe joint and through the diverless pipe connector and through the tube. In a preferred implementation, the flexible pipe joint includes alternate elastomer layers and metal layers reinforcing the elastomer layers, and a receptacle of the diverless connector is mounted on a foundation such as a suction pile on the seabed, or a pile grouted in a bore in the seabed.

LIQUID-COOLED BRAKE ASSEMBLY WITH REMOVABLE HEAT TRANSFER INSERT
A brake for a rotating member is disclosed. The brake is used with a liquid coolant, and includes a housing for containing the liquid, a stationary element disposed in the housing, a wear plate disposed on the stationary element, a friction element coupled to the rotating member for contacting the wear plate, and a removable heat transfer insert disposed adjacent the wear plate and in fluid communication with the coolant, the heat transfer insert consisting of a non-galvanic material.
Liquid-cooled brakes for machines for use in the oil and gas, marine, and logging industries and other industrial environments, excluding brakes for land vehicles or earthmoving machinery
A double-ended flexible pipe joint (26) has first and second extension pipes (51, 52) extending from opposite ends of an outer housing (50), and first and second primary annular elastomeric flex elements (71, 74) mounting the first and second extension pipes (51, 52) to the outer housing (50). An inner housing (80) is disposed in the outer housing (50), and first and second secondary annular elastomeric flex elements (81, 82) disposed in the inner housing (80) mount the first and second extension pipes (51, 52) to the inner housing (80). Tension upon the first and second extension pipes (51, 52) places each of the first and second primary flex elements (71, 74) and each of the first and second secondary flex elements (81, 82) in compression. The first and second secondary flex elements (81, 82) contain fluid pressure within the first and second extension pipes (51, 52) so that the first and second primary flex elements (71, 74) are not subjected to the fluid pressure within the extension pipes (51, 52).
F16L 27/103 - Adjustable jointsJoints allowing movement comprising a flexible connection only in which a flexible element, e.g. a rubber-metal laminate, which undergoes constraints consisting of shear and flexure, is sandwiched between partly curved surfaces
A flexible joint (27) has an extension (54) mounted to a housing (51,52) for relative angular displacement. Two or more annular elastomeric flex elements (61,62) are stacked in a co-axial fashion and joined mechanically to mount the extension (54) to the housing (51,52) so that the flex elements react in parallel to angular and axial displacements of the extension with respect to the housing so that tensile load upon the extension (54) places each of the flex elements (61,62) in compression to split and share the tensile load among the flex elements in proportion to their relative axial stiffnesses. Therefore, for a given housing size or footprint, the overall load capacity is increased, and the lifetime of the flexible joint is increased for a given load capacity. The flex elements may have a common center of rotation, and the flex elements may be disposed either on the same side of the center of rotation or on opposite sides.
F16L 27/103 - Adjustable jointsJoints allowing movement comprising a flexible connection only in which a flexible element, e.g. a rubber-metal laminate, which undergoes constraints consisting of shear and flexure, is sandwiched between partly curved surfaces
A flexible pipe joint (27) has two annular elastomeric flex elements (74, 75) stacked in a co-axial fashion at an inner radius (R1) from a common center of rotation (63), and at least one elastomeric flex element (61, 62) disposed at an outer radius (R2) from the common center of rotation (63). The flex elements (74, 75) at the inner radius are coupled mechanically in series between the extension pipe (54) and the housing (50) of the flexible pipe joint, and the flex element (61, 62) at the outer radius is coupled mechanically in parallel with the series combination of the inner flex.elements (74, 75). The inner flex elements (74, 75) isolate the flex element (61, 62) at the outer radius from transport fluid, and the flex element (61, 62) at the outer radius reduces the axial compression of the inner flex elements (74, 75). Thus, the inner flex elements (74, 75) may have a reduced radius and a different composition to handle a higher loading of heat and pressure.
