Moving MOUs to sheltered waters or drydock facilities for surveys is disruptive and expensive. Using the experience gained from several years of dealing with floating production units and surveying drilling units on location, DNV is now preparing a Recommended Practice (RP) to allow mobile offshore units to operate on location by optimizing survey routines without compromising on quality, safety and integrity.

More practical design and construction of the units, established condition monitoring technologies, effective corrosion management programs, emerging technologies for less intrusive or alternative means of inspections, ingenious maintenance and continuous survey regimes are some of the elements that make this change possible.

DNV’s recommended practice will be supported by explicit changes in the rules so that surveys carried out in an MOUs normal operating environment can be adopted as ‘normal’ instead of treating them as ‘special’ cases that require application for acceptance.
