Designed by Rolls-Royce Marine and constructed by Italian shipbuilder Fincantieri, RV Kronprins Haakon is an icebreaker and research vessel owned and operated by the Norwegian Polar Institute. The ship, which was completed in 2018, is equipped with a hangar for two helicopters and is equipped to carry out oceanography, marine biology and geology. Kronprins Haakon is powered by a diesel-electric propulsion system consisting of four medium-speed diesel engines that produce power for azimuth and bow thrusters. For this application Walton Engineering supplied 150mm and 250mm bore stainless steel pneumatically operated valves complete with 4-20mA electro-pneumatic positioners. All
A valve was required to control the temperature of lubricating oil on a compressor to be supplied to the Al Shaheen oil field in Qatar. Al Shaheen is one of the world’s largest and most complex oil fields producing 300,000 barrels of oil per day. The customer’s specification called for a carbon steel valve body with a stainless steel operating mechanism. While the common grades of these materials fall within Walton’s standard product range, an unusual feature of the requirement was that more specialised grades of material were called for on certain parts of the valve. Our
Three-way valves were required to control the flow of sea water through the condensers of the chilled water system on superyacht Eclipse. While gas operated valves would be the usual choice for this application, the customer wanted to control the valves electronically using a 0-10V electrical control signal generated by the chillers. Walton was able to meet this requirement by supplying electrically operated valves fitted with actuators incorporating 0-10V positioners. Each actuator was also fitted with a potentiometer to provide feedback of the valve’s rotor position to the positioner. This solution meant that no further electronic sensing
