Underwater ROV eWROV

The latest addition to Saab Seaeye’s underwater portfolio, the eWROV is a full-sized Class III B ROV system. Electrification is the key to improved performance, and the eWROV takes electric underwater vehicle capabilities to the next level. The goal of carbon neutrality is a growing focus among the global community, and the eWROV has been designed with eco-responsibility in mind. As well as being more efficient, electric systems use limited oil, making the eWROV significantly more environmentally friendly than equivalent hydraulic work-class systems. The eWROV has the in-built capability to be operated from onshore command and control centres. A common technology ecosystem and intelligent architecture of configurable hardware and software modules, providing real-time system control and feedback. Dual 7 function robotic manipulators offering advanced control, more precise positioning, increased dexterity and greater reliability. Requiring less maintenance than ever, the eWROV system is inherently reliable. Electric thrusters are the key to electrifying WROVs; capable of generating 560 kgf, the eWROV’s power efficiency is far greater than hydraulic systems, with better acceleration, braking and reversal. Conventional high-voltage AC power transmission systems result in large, heavy subsea transformers on the ROV and PDUs on the surface. State of the art DC power transmission system enables significantly smaller and lighter units, both topside and subsea. It also allows the use of smaller diameter umbilicals and existing client-owned umbilicals. Electric manipulators are enablers for electrifying WROVs, and support the whole electrification ethos.
