A product having a metal strip and a central longitudinal axis. The strip has two or more strip parts, each having a common radius of curvature defining a helix having an angle being offset from one another in the direction of the axis. A cross section of the strip parts causes them to be interlocked together throughout their lengths to define a flexible metal tube. The outside diameter of the tube is between ⅜″ and 1⅜″ and the helix angle of each strip part is between eight and thirty degrees.

A longitudinal element produced with a core made of high-strength fibers and at least one metal casing, preferably steel, surrounding this core. In this way, there is the significant advantage that these high-strength fibers, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibers with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period

A locked coil wire rope includes a circular steel wire inner layer, a central metal core, and a Z-shaped steel wire outer layer. The central metal core has a structure of 119W, 119S, 126WS, 131WS, 131SW, 149SWS or 155SWS. The circular steel inner layer includes at least two circular steel wire layers, and a number of steel wires of circular steel wire layer is no less than 18. The Z-shaped steel wire outer layer includes at least one Z-shaped steel wire layer, and a number of steel wires of the Z-shaped steel wire layer is no less than 51. A capacity expansion framework is further disclosed.

A mooring member comprises a rope configured for extending between a vessel floating in a body of water and an anchoring device. The mooring member comprises a plurality of functional elements, wherein a first functional element is wound onto at least a portion of the rope, a second functional element is wound onto the first functional element, and so on, until an outermost functional element is wound onto a second-to-outermost functional element. The functional elements are wound in a helical configuration, and are configured to provide at least one of the following functions: damage protection, buoyancy, optical detection, sonar detection, stiffness control, and anti-fouling.

According to embodiments of the present invention, a stranded conductor is formed in which the occurrence of defects, such as strand unevenness of filaments and outward protrusion of filaments, is inhibited. According to embodiments of the present invention, a stranded conductor (1a) includes soft filaments (2a) stranded together. The soft filaments (2a) include a soft filament made of an aluminum material, disposed along a center (101), and include six soft filaments, twelve soft filaments, and eighteen soft filaments made of an aluminum material, disposed around and concentrically with the center. The filaments are softened filaments that are softened. A lay length (Pa) is from 6.2 times to 15.7 times a conductor diameter of the stranded conductor.
