§ 30 Safety-clearance of activities
Planned activities shall be cleared as regards safety before they are carried out. Which conditions shall be met, shall be evident from the clearance, including which measures shall be implemented before, during and after the work so that those participating in or who may be affected by the activity, are not injured, and so that the likelihood of mistakes that can lead to hazard and accident situations is reduced.
Section last changed: 01 January 2011
In order to fulfil the safety clearance requirement, a work permit system should be used.
When activities are cleared in accordance with this section, a safe job analysis should be conducted when sub-activities are not covered by procedures, the procedures can conflict with each other, or the activities are new to the personnel involved.
As regards conducting safe job analyses, Appendix C.3 to the NS-EN ISO 17776 standard should be used in the area of health, safety and working environment. With regard to conducting a job safety analysis, see, inter alia, the last paragraph in C.3.3, the party responsible for carrying out the work and the workers who actually carry it out, should participate, possibly also the persons responsible for the system and area.
To fulfil the requirements for measures, the Guidelines for Offshore Marine Operations (GOMO) should be used for this type of activities. In respect of measures relating to discharge of drainage water, refer to GOMO Chapter 7.8 Discharges from Facilities.
To fulfil the requirements for measures, Chapters 4.10.3, 8.2, 8.3, 8.4, 8.6 and 8.7 of the NORSOK D-010 standard and Norwegian Oil and Gas’ Guideline no. 117 should be used for drilling and well activities in the event of handover of wells between units, with the following addition: the wells' barrier status should be tested and verified.
In respect of tandem transfer of hydrocarbons from an FPSO or FSU to a shuttle tanker, it should be assessed whether to reduce other shipping activities to or from the FPSO or the FSU.
Handover of wells between units means handover between production, well service, operation, maintenance, etc.
