Re­mote con­trol ve­hi­cle for pipeline in­spec­tion

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Equipped with a scanCONTROL laser scan­ner from Mi­croEp­silon, a spe­cial ve­hi­cle in­spects the in­side of a pipeline for de­for­ma­tions and cracks. This mo­bile de­vice is used in harsh en­vi­ron­men­tal con­di­tions and high am­bi­ent tem­per­a­tures, e.g. in the mid­dle of the desert and is ideally suited to au­to­matic in­spec­tion and record­ing of mea­sured data.

To meet safety reg­u­la­tions, the in­spec­tion of the in­ter­nal parts of pipe­lines is manda­tory, as any de­for­ma­tions can lead to cracks, which could re­sult in com­plete pipe fail­ure or, in the worst case, to per­sonal in­jury. The crit­i­cal fac­tor is the weld seam. Ger­man com­pany Dekra de­vel­oped a fully au­to­matic ve­hi­cle that solves this task by us­ing a com­bi­na­tion of vis­ual in­spec­tion and ge­o­met­ri­cal mea­sure­ments per­formed by a scanCONTROL laser scan­ner avail­able from Bestech Aus­tralia.

To make the ve­hi­cle suit­able for dif­fer­ent types of pipeline in all re­gions around the world, it is pro­tected against sand, dust and am­bi­ent tem­per­a­tures up to 100°C. In com­bi­na­tion with the fifth wheel on the top of the ve­hi­cle pressed against the top of the pipeline, the ROV can travel up a high gra­di­ent of around ± 45°. All data out­put can be logged and used to trig­ger an alarm (if de­sired) as soon as an ano­maly is found in the ge­om­e­try (round­ness, de­fects, welds, etc.).
