GL Noble Denton issues guidelines for float-over installations and mooringsNews // January 31, 2011
GL Noble Denton has issued new guidelines for float-over installations and for moorings. The guidelines have been developed on the basis of GL Noble Dentonís experience as a leading consultancy and assurance service for floatover operations and mooring installations.
They are now available for oil and gas companies, designers and contractors and describe current ďindustry good practiceĒ which help oil and gas companies to have their mooring systems or float-over operations approved by GL Noble Denton.
An approval by GL Noble Denton may be a requirement of an insurance warranty or to ensure that operational risks are as low as possible.
The float-over guidelines (0031/ND) are an industry first and reflect the current popularity of float-over operations. The guidelines draw on GL Noble Dentonís unique and extensive experience of float-over operations, both on to floating hulls and fixed platforms.
The recent trend to use dynamic positioning (DP) for the float-over operation is also covered. The guidelines now complete the whole topside or deck installation sequence namely, loadout, transportation and the float-over operation itself.
The mooring guidelines (0032/ND) embrace not only the ISO 19901-7 standard on station keeping, which has also had GL Noble Denton input, but also address quayside moorings and short term moorings for marine operations such as load outs and float-overs.
The guidelines are drawn from the experience and involvement of GL Noble Denton in the design and operation of floating installations, mobile offshore units and installation vessels around the globe.
Pioneering mooring input of GL Noble Denton to the industry dates back to the1970s and included the design and installation of the mooring system for the first Floating Production Unit in the North Sea Transworld 58 in the Argyll field.
GL Noble Denton continues to play a role in assisting in the development of the ISO 19901-7 standard and in running the Joint Industry Programme on mooring integrity.
The guidelines were developed by GL Noble Denton Technical Policy Board, which includes 15 worldwide Technical Authorities, assisted by over 60 Technical Correspondents who contribute their expertise and knowledge acquired in different areas of the world.
