Side-spar cable-stayed bridge Side-spar cable-stayed bridge A side-spar cable-stayed bridge may be an otherwise conventional cable-stayed bridge but its cable support does "not span the roadway", rather being cantilevered from one side. The Esplanade Riel illustrated is located in Winnipeg, Manitoba, Canada. This bridge is intended for pedestrian use only and has a restaurant in its base. In the example below the cable paths are aligned with the bridge centerline, so that structurally it differs only in the transfer of stresses through the tower to the foundation. The side-spar principle is not limited to a straight bridge, however. The tower could be offset
Cable layer it could fulfill both roles: as a cable layer or a cable repair ship. To ensure that cable is laid and retrieved properly, specially designed equipment must be used. Different equipment is used on cable-laying ships depending on what their job requires. In order to retrieve damaged or mislaid cable, a grapple system is used to gather cable from the ocean floor. There are several types of grapples, each with certain advantages or disadvantages. These grapples are attached to the vessel via a grapple rope, originally a mix of steel and manila lines, but now made from synthetic materials. This
