to be non-metallic to meet non-contaminating criterium as any exposed metal can interfere with the sample quality of trace elements, such as iron and zinc, by the time they return to the surface. A lighter-weight solution would also allow deeper ocean sampling, compared with metal-clad electromechanical cables ordinarily used for campaigns. These older models of cables are considered too heavy for winching within safe working limits when lowered to depths of more than 5,000 meters.Ideally, the solution had to have no exposed metal, lower the weight and deploy rapidly. It also had to be strong enough to

Flying new Routes Subsea

;go here, if you see a pipeline, follow it, or if you see a monopile, perform an inspection around its circumference’. This has all been demonstrated in trials.  The next set of autonomous developments will be very exciting. In the near term we want to develop the HAUV track and survey buried cables autonomously. Various pipe tracking technologies are currently being trialed.  This is expected to be a quick development as we can use similar algorithms to those used to track visible pipelines.”It’s not been an easy journey, but Ward sees that some are seeing the potential. &ldquo

Offshore wind: The making of a (supply chain) star

Delaware outlined the opportunity in U.S. offshore wind: 5,000 miles of offshore cabling and 1,700 turbines, it turns out, are bundled into current state-side plans. Yet, serious observers of the first U.S. offshore wind installations saw inefficiency: unwieldy lifts; few specialist vessels on-hand; and cables were “just cables.” Supply chain innovation, people say, lags other industries.In Europe, where offshore turbines heavily dot maritime maps, there’s acknowledged room for innovation in turbine construction, support shipping and subsea. Installations here, too, can seem encumbered
