Design Approvals
For non standard products that require their design to be reviewed under the principles of the NS-1™ Standard there are 4 approval levels:
Level 1 - Quality & Inspection for Manufacture
The lowest level of review, where the applicants Manufacturing, Assembly and Inspection procedures alongside Manufacturing Drawings are checked to ensure equipment meets requirements as specified within the appropriate section(s) of the NS-1™ Standard or other related Standards such as NS-2™ if applicable.
Level 2 - Review for Failure Prevention
The equipment is assessed to show that it has been designed with consideration to failure avoidance. Evaluations are conducted based on failure modes more commonly observed when equipment is used for purposes to which they were designed, and may require calculations to be performed for determining the maximum loading conditions equipment may be subjected to.
Level 3 - Fitness for Purpose (includes Levels 1 & 2)
Equipment must be assessed for functionality with tests performed and witnessed by the reviewing engineer in order to demonstrate that the equipment is capable of meeting and performing the physical functions to which it was designed for.
Testing may be conducted either by:
- Surface Testing
- Down hole Testing
Level 4 - Measurement and analysis
All of or any combination of Levels 1, 2 and 3 plus a full process audit to assess, analyse and measure the company’s capability to maintain the necessary engineering and manufacturing controls on a continual basis or for the duration of a specific contract life.
