In 2009 a leading exploration, development and production company launched a project to extract oil and gas from the Olowi field off the coast of Gabon. The project involved an FPSO facility acting as a production centre for four wellhead platforms, and an existing vessel, was to be used in the operation. As part of a drive to ensure that safety provisions were as comprehensive as possible, it was required to replace all of the single isolate units on the floating facility with double block and bleed valves. Clearly, weight and space were both major concerns, and it was therefore essential that the new equipment was installed with a minimum of additional components and pipe work. A large number of valves were to be replaced – more than 150 in total – and, given the scale of the upgrade, the traditional method of installing additional single isolate units was unfeasible as it would have approximately doubled the weight and space required for the system. Oliver Valves supplied 161 Twinsafe valves with bore sizes ranging from 1in to 10in. The valves were flange mounted with a range of ANSI class 900lb and 1500lb fittings. The standard length of Twinsafe valves meant that the existing single ball valves could simply be replaced with a cartridge double block and bleed unit, with no need for any additional pipe work
