Abstract: A riser apparatus and method according to which an anchor is installed on the sea bed and a riser conduit is pivotally mounted on the anchor. The riser conduit is provided with end connectors for connection to an upper riser section leading, respectively, to a production platform and a lower riser section leading to a wellhead or subsea storage or export facility. The riser conduit is preformed into a predetermined curved shape and is provided with stiffening webs to safeguard its rigidity, so that it substantially retains its predetermined shape when movements are transmitted through the riser conduit from the upper riser section to the lower riser section, or conversely.

Abstract: The error offset and the error magnitude of a data stream in a Read-Solomon code is calculated using the same architecture. The advantage this method has over previous techniques is its simplicity of design and the minimum steps required to convert the syndrome information into an error location and correction pattern. The maximum of four cycles (steps) needed to compute the offset and correction pattern allows for a correction to be applied in the byte time immediately following receipt of the last check byte.

Abstract: The present invention relates generally to an oxidation and corrosion resistant coating composition produced by a vapor phase co-deposition of transition metals on metallic components. In particular, this coating includes aluminum and silicon and the coated substrate may comprise precious metal, nickel, cobalt or MCrALY. Such coatings are particularly useful in protecting nickel and cobalt and iron-based superalloys from heat corrosion and oxidation attack, especially during high temperature operation, e.g., gas turbine and jet engine hot zones.
