These systems, from Schilling's Acergy Core Vehicle (ACV) line, are the product of close collaboration with Acergy, a leading seabed-to-surface engineering and construction contractor for the offshore oil and gas industry. Schilling was selected by Acergy in 2006 to produce the standard ROV system for the company's next-generation remote intervention fleet. The ACV, which is based on Schilling's standard ultraheavy-duty UHD system, adds power, flexibility, and enhanced vehicle control to Acergy's fleet.
The four ordered ACV vehicles have 150-shp power packs. They are rated for 3000-meter operation, and can be easily upgraded for 4000-meter depth ratings. The systems feature eight thrusters, four vertical and four horizontal, for extra stability. The ACVs are equipped with Schilling's StationKeep utility, the only dynamic positioning system available for ROVs. The ROVs also use Schilling's Digital Telemetry System, which includes advanced capabilities such as HDTV.
ACV systems 04 and 05 will be delivered in June to operate from the Sapura 3000, a new-build heavy- lift and pipelay vessel that will perform deepwater construction and pipelay in the Asia Pacific region. Both ROV systems include Schilling's extended-excursion XE TMS unit, which is equipped with an unprecedented 1500 meters of 27-mm tether to support pipeline touchdown monitoring. The XE TMS units feature dual thrusters, variable-speed spooling, and a flexible control system for safe, efficient operation.
ACV systems 06 and 07 will be configured similarly to ACV 04 and 05, and will include XE TMS units. Both systems will operate from the heavy construction vessel Skandi Acergy. They will be delivered in November 2007.
Headquartered in Davis, Calif., with regional offices in Houston and Aberdeen, Schilling Robotics designs and delivers subsea robotics, control systems, and components for use in the world's harshest environments.
