A steel catenary riser (SCR) is a common method of connecting a subsea pipeline to a deepwater floating or fixed oil production platform. SCRs are used to transfer fluids like oil, gas, injection water, etc. between the platforms and the pipelines.
A commonly used configuration is the catenary anchor leg mooring (CALM), which can be capable of handling very large crude carriers. This configuration uses six or eight heavy anchor chains placed radially around the buoy, of a tonnage to suit the designed load, each about 350 metres (1,150 ft) long, and attached to an anchor or pile to provide ...
A chain hanging from points forms a catenary. The silk on a spider's web forming multiple elastic catenaries.. In physics and geometry, a catenary (US: / ˈ k æ t ən ɛr i / KAT-ən-err-ee, UK: / k ə ˈ t iː n ər i / kə-TEE-nər-ee) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field.
This new anchor concept has only been recently developed but has been tested both in the lab and field. The different components of the DEPLA can be seen in the labeled diagram in the figure. The Omni-Max anchor pictured is a gravity-installed anchor that is capable of being loaded in any direction due to its 360-degree swivel feature. [12]
English: An image showing the difference between top and side risers, and open and blind risers. Based on diagram on from Degarmo, E. Paul; Black, J T.; Kohser, Ronald A. (2003), Materials and Processes in Manufacturing (9th ed.), p. 287.
The catenary wire is made of copper or copper alloys of 70, 120 or 150 mm 2. The smaller cross sections are made of 19 strands, whereas the bigger has 37 strands. Two standard configurations for main lines consist of two contact wires of 100 mm 2 and one or two catenary wires of 120 mm 2, totaling 320 or 440 mm 2. Only one contact wire is often ...
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles.
A catenary pole of the system. Catenary wires and contact wires are tensioned by individual tension balancers. The basic system unit is an elementary electrical section consisting of a segment of one or more parallel tracks, each with a contiguous contact (or catenary or trolley) wire for the locomotive pantograph and an electrically separate feed wire.
