Street’s role in North Sea oil

Chapel-en-le-Frith overhead crane makers Street Crane Company have installed a 72-tonne gantry crane for JDR Cable Systems of Hartlepool.

JDR will use the crane to produce multi-core umbilical cables for offshore oil and gas platforms.

The factory crane package includes a double girder crane of 11 metres span and 72 tonnes safe working load, with a VX hoist that was custom built at Street Crane’s factory. The crane is supported on a freestanding gantry 30 metres long. Unusually, the gantry was installed prior to the building shell and the completed crane was used in the assembly of the carousel at the core of the cable fabrication machine. Once the carrousel was installed, end-stops were fitted to the gantry to limit crane travel and protect the top part of the machine.

Street Crane’s sales director, Chris Lindley-Smith, said, “It is quite unusual for an overhead crane to be pre-installed and used in the equipment build phase. At JDR Cable Systems, the crane is a key part of the manufacturing process, ensuring the productivity of this capital intensive and highly specialised operation.”

The crane is engineered for safety and reliability. Features of the crane include remote radio control with push-button pendant backup, inverter control for smooth operation and heavy duty M5 rated mechanisms on the hoist.

Marine cables are vital to the oil and gas industry. The new process enables power, control, instrumentation and communication/data cables to be raised from reels and twisted with packing and support material to form the umbilical.
