Wireless technologies reduce costs and cut operational risk
Wireless subsea cameras, a smart wireless network linking wells, rigs and drilling units, and an ultrasonic scanner on flexible risers are among the latest wireless innovations on offer. Sean Ottewell reports.
Cámaras submarinas inalámbricas, una red inalámbrica inteligente que conecta pozos, plataformas y unidades de perforación, y un escáner ultrasónico en elevadores flexibles son algunas de las últimas innovaciones en oferta en el campo de la tecnología inalámbrica. Informe de Sean Ottewell.
Drahtlose Unterwasser-Kameras, ein cleveres Drahtlos-Netzwerk, das Bohrlöcher, Takelage und Bohreinheiten verbindet, und ein Ultraschall-Scanner an flexiblen Steigrohren gehören zu den aktuellsten Drahtlos- Innovationen im Angebot. Sean Ottewell berichtet.
R
emote camera and video technology specialist EV has unveiled the industry’s first commercial wireless subsea camera. Described by the
company as ground-breaking, the new tool can stream live video over distances of up to five metres back to a pick-up point such as an ROV or hard-wired receiver, and has the potential to significantly reduce both operational risk and time. Te battery-powered Neptus wireless subsea camera (WSC) provides a major step change for the subsea sector through its novel features and has the capability to operate at depths of up to 350 metres for ten hours. Applications for the camera and
receiver include providing multi- perspective views of complex operations such as subsea tool intervention, construction and remote monitoring
of subsea equipment. Te camera’s through-water wireless radio frequency (RF) technology has been supplied by a specialist in the field, WFS Technologies. Among other key applications that the Neptus WSC provides are:
● Providing a wider perspective view of subsea ROV operations;
● Making up subsea connections between jumpers and manifolds, risers and templates or vessels - anywhere that multiple views or perspectives are required in order to bring together two or more items and which are currently achieved by using a second or third ROV;
● Tooling/subsea controls applications which provide an additional view of operations such as subsea intervention around templates or wellheads and valve manipulation.
● Remote subsea monitoring. For example, leak monitoring or structural assessments from remote locations where cabled solutions are not practical.

Te Neptus WSC tool was launched commercially in June and will be followed in January 2012 with an advanced version that will feature an increased pressure rating, longer subsea life and pan and tilt zoom capability, and a wireless range of up to ten metres. Like EV, WFS Technologies produces customisable resources for a variety of offshore settings and customers. Te company is a leading supplier of radio and acoustic systems and solutions, including wireless communication, navigation and power transfer. In the Sultanate of Oman, MARAC has undertaken the design, deployment, integration and support of
