CSIP, part of ECA Group, is set to launch the first five-function electric underwater manipulator arm at Ocean Business 2009, stand H2. ARM 5E has a minimum lift capacity of 25kg and shares many characteristics with conventional hydraulic arms, but its reduced weight and improved mobility gives it a competitive edge.
The all-electric ARM 5E can be mounted in the same fixture as hydraulic arms, however without the need of a skid, valve pack or hydraulic pump. This distinct feature saves weight and as a result allows greater vehicle maneuverability.
Like hydraulic arms, ARM 5E can be used for a wide range of applications such as cleaning debris, turning values and cutting, but with improved accuracy and a more precise operation. Using a digital positioning feature, the electric arm achieves accuracy of 0.5mm.
With computer control electronics position feedback, users can detect the location of ARM 5E at all times. In addition, it has a learning and memory function, which remembers and repeats the maneuvers performed by the arm.
Another key aspect of the ARM 5E’s design is its modularity. Should a part break, it can easily be repaired with spares or refitted with a specific modular section on site, rather than having to be returned to a central repair base. Other features of the AEM 5E include the following:
- Rated for use at depths down to 3,000m
- Radius of 1.044m reach and a slew of 120°
- Constructed of HE30 hard anodised aluminium, 316 stainless steel and nickel aluminium bronze
- Brushless electric motors that operate in oil
- Oil-filled actuator and junction box voids that are pressure compensated to 0.4bar above ambient
- 7,500m rated seals
- If a seal breaches, water cannot leak in
- User-friendly surface control unit; joystick with up/down movement and left/right (slew) controls; twist function to operate jaw rotate and a thumbwheel to control open/close jaw
