Offshore Physical Environmental Guidelines
Appendix G – Equipment List


This is not intended to be an approved list of equipment. It is provided to give the Operator information regarding the types of instruments which have been used in the offshore in the past. It is incumbent upon the Operator to ensure that all proposed instrumentation is appropriate for use in the area of operation, that it meets the functional specifications as described in Appendix B, and to document its capabilities in the Program Description prior to use. Operators are encouraged to evaluate new technologies as they become available.

Note i: g.f. = "grandfathered" equipment. Although the equipment may be used as part of an existing system, it may not be added as part of a new system.

Note ii: Temperature and pressure instruments require calibration certificates and correction cards issued by an acceptable laboratory.

Note iii: Wave radar systems must be calibrated to ensure proper functioning. Systems that are new to Canada or that are proposed for substantially different locations than previous usage, may need to be verified against an alternate wave measurement system.
