Section last changed: 01 January 2018

To fulfil the requirement relating to testing, complete overhaul and recertification so that the equipment can fulfil its required functions, the NORSOK D-001 standard, Chapter 6.35.3, cf. Section 49 of the Facilities Regulations, and the NORSOK D-010 standard, Chapters 4.2.3.5 and 4.2.3.6 as well as tables 15.4, 15.14, 15.19, 15.21, 15.32, 15.37, 15.38, 15.47, 15.53, 15.57, 15.58 and 15.59 and Appendix A, Table 39, DNVGL-OS-E101 as well as DNV-RP-E101 should be used. See Section 47 as regards this type of equipment in well interventions and overhaul of subsea wells.
Complete overhaul and recertification as mentioned in the second subsection, may be carried out continuously and in a manner which ensures that single components and the whole unit will be overhauled in a rolling five year period. The complete overhaul does not necessarily imply a full dismantling of all the parts, cf. design, operation and maintenance history, lifetime and associated risk assessments (classification) etc., but must be carried out in a way that will be eligible for recertification.
