    Abstract: Process for the production of high-purity isobutene starting from a stream prevalently containing MTBE (Methyl-Tert Butyl Ether) or ETBE (Ethyl-Tert Butyl Ether) which essentially comprises the following areas in sequence: • a fractionation area for obtaining a stream of high-purity MTBE or ETBE; • a cracking area of said stream of MTBE or ETBE for obtaining an outgoing stream prevalently containing isobutene and the relative alcohol, methanol or ethanol; • a washing area with water of the stream leaving the cracking area for the recovery of the relative alcohol, in order to obtain a stream containing isobutene, the ether fed and light compounds and a stream substantially consisting of water and relative alcohol, with a relevant fractionation section for separating the washing water to be recycled to the same washing area from the relative alcohol; • a fractionation area of the stream containing isobutene, the ether fed and light compounds for separating a stream of high-purity isobutene. The process can be possibly integrated with a process for the production of MTBE or ETBE.

    Abstract: A vessel for laying a pipeline includes a plurality of workstations disposed along a pipelaying path that includes an upstream portion away from a first end of the vessel and a plurality of ramps in the region of the first end of the vessel. The plurality of ramps includes a first ramp which is disposed along the pipelaying path, whose inclination is adjustable and which has a first upstream end and a second downstream end, and a second ramp which is disposed along the pipelaying path downstream of the first ramp, whose inclination is adjustable and which has a first upstream end and a second downstream end. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel. An external ramp assembly is provided, including ramps and that can be pivoted relative to one another and locked in a selected position by a locking arrangement.

    Abstract: A method of laying conduit at sea from a reel vessel includes the steps of laying conduit, for example pipeline or umbilical, from a first reel which rotates about a first substantially vertical axis. Conduit is laid from a second reel of conduit rotating about a second substantially vertical axis spaced apart from the first axis. A portion of the route travelled by the conduit during the step of laying conduit from the first reel of conduit is substantially the same as a portion of the route travelled by the conduit during the step of laying conduit from the second reel of conduit, for example, the conduit from the second reel may pass around a part of the periphery of the first reel and then follow substantially the same path as previously travelled by the conduit laid from the first reel.
