Rotork Fluid System has won the order for heavy-duty hydraulic actuators and control panels on the Statoil Kristin production platform New Development project in the Norwegian North Sea.
The order, awarded within the terms of Statoil's framework agreement, encompasses 74 Rotork LH range linear hydraulic spring return actuators to operate Petrovalves gate valves in sizes from 50 mm (2") Class 1500 to 300 mm (12") Class 600, and Control Seal rising stemball valves in sizes from 50 mm (2") Class 300 to 150 mm (6") Class 600.
Each actuator will be supplied with a Rotork designed local control panel, for direct connection to the platform's hydraulic ring main. The compact and lightweight design of Rotork's linear actuators, some of which are pictured here at the new Fluid System production plant in Italy, made an important contribution to winning this order, which was awarded by Statoil's engineering contractor, Aker Kvaerner.
To comply with the stringent contract specification, each actuator is chemically cleaned and flushed internally after manufacture to safeguard commissioning activities and enhance long-term reliability. Rotork believes that it is the only manufacturer of heavy-duty fluid power actuators to have invested in a dedicated in-house chemical cleaning plant to offer these additional safeguards.
