The SlipSmart system was designed to demonstrate that the system would meet and could in fact exceed the guidelines set forth in industry for a lockout system.
The guidelines to be followed were as follows:
- Snubbing equipment shall incorporate design features such that a positive, measureable and recordable transfer of load can be made between slips.
- Snubbing equipment shall be designed with (electro/hydraulic) interlock(s) that will not allow accidental release of pipe, at any time, in either heavy or light mode of operation.
- Ergonomic features shall be considered in relation to visual confirmation of slip function, load transfer and with respect to dropped object protection.
- Bypass of the interlock(s) to enable operations such as running BHA assemblies shall be possible, but controlled by PTW, adequate procedure and supervision.
