Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve a series of A-range actuators to IQ3 actuators which function penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A sequence of A-range actuators had reached the tip of their operational life after long service in a difficult environment. BAE Systems needed to retain all the benefits of electrical actuators, so IQ3 actuators have been chosen. These had to be specially tailored by Rotork to beat issues round confined areas and difficult access.
pressure gauge 10 bar and IS gearboxes were mechanically adapted in order that each actuator and gearbox could be operated by hand without coming into the confined area. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined space access.
Actuators throughout the IQ range are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked display with configurable data logger performance, and an absolute place sensor provides reliability and accuracy.
