in our business,” said Schilling, emphasizing the importance of reliability and design. While FMC Schilling Robotics has de- signed its ROV systems to be robust in the deepest water, ev- ery design effort has been made to keep maintenance simple and accessible through comprehensive system diagnostics and intuitive maintenance solutions.
FMC Schilling offers two ROV models, the UltraHeavy- Duty (UHD) and the Heavy-Duty (HD) remotely operated ROV systems. The HD is equipped with 150 hp (112-kW) motor for propulsion and hydraulic pump actuation with depth rating of 3000 m (4000 m optional) and 425-m tether length for medium-duty capabilities in the construction area. The UHD ROV features 200 hp (149-kW) motor, is rated to 4000 m, and has an 850-m tether and is designed for heavy-duty applica- tions and construction requirements.
ROV pilots, sitting at dual consoles on the surface, perform complex operations while the ROV automatically compensates for challenges of the deep sea environment, like high currents
and low visibility. The working tools (arms) of the ROV are the manipulator systems. Manipulators perform a variety of intervention tasks. The manipulator systems comprise an arm on the right side that features dexterity and an arm on the left side that is designed for powerful and heavy duty operations. The Titan 4 manipulator, for example, is primarily titanium with a maximum reach of 1922 mm and lift of 122 kg at full reach, and is depth rated to 4000 m with an optional depth rating of 7000 m. These systems range from the five-function RigMaster to the seven-function position controlled Titan 4. The RigMaster is anodized aluminum, stainless steel, and titanium. Other manipulators available from FMC Schilling include the Conan, Orion, and Atlas manipulator systems that are made from anodized aluminum and stainless steel. FMC Schilling Robotics is a global supplier to the seabed-to- surface engineering, construction and energy services industry with more than 2000 manipulator systems operating on virtually every work-class ROV in the world. In 2012, over 250 robot arms
