Deepwater pipeline-repair system deployed to Mediterranean
The latest phase in development of a deepwater pipeline-repair system received full-scale trials earlier this summer in Norway and has been deployed on standby for the Trans-Mediterranean pipeline by operator SNAM. In Stavanger harbor in June, Sonsub International Inc.`s Arcos diverless repair system underwent successful shallow-water trials that employed all the system`s equipment. (Arcos is an Italian acronym for attrezzaturre per la riparazione di condotte sottomarine-subsea pipe repair tooling.) The system is the most recent development in an evolution of efforts to develop a diverless pipeline-repair system for deepwater use. The prototype PRS (pipeline repair system) received deepwater (300m) trials offshore southern Italy in 1992. It used two work-class ROVs. In 1995, a modified PRS, renamed the DSRS (diverless sealine repair system), underwent shallow-water trials, also offshore southern Italy, that led to a modification of its pipe-lifting system. In 1997, the DSRS underwent more shallow-water trials, this time in Stavanger, which led to improvement in the spool-installation module. According to Sonsub, this refined version of the Arcos employs a low-force modular concept that is ROV supported and can be adapted quickly and easily to a wide range of pipe sizes.
