The Oil & Gas UK (OGUK) first saw life in 2007 following the rebranding of the UK Offshore Operators Association (UKOOA), an organisation created by the UK government in 1996 to standardise the products and services supplied to the offshore industry. The products falling under the OGUK’s remit include power and instrumentation cables. As part of its mandate the OGUK speaks for and represents the entire offshore sector operating on the UK continental shelf.
The guidelines developed by UKOOA for cables are complementary to British Standards, including BS6883 Type SW4 cables and BS7917 tinned copper armoured shipwiring cable. As such, cables approved by OGUK can be deemed to comply with the relevant British Standards.
