While it is a "Recommended Practice" and not a legal requirement, it is widely treated as the industry's foundational safety standard. It includes rigorous strategies for:
Mechanical Integrity: Selecting metallurgy and "soft goods" (seals/gaskets) to prevent leaks or failures.
Environmental Protection: Minimizing emissions and protecting marine life during operations.
Weather Protection: Guidance on seals, purges, and shielding for instruments exposed to harsh outdoor conditions. 4. Balancing Performance vs. Maintenance
A major theme of RP 551 is the "compromise" between how well an instrument performs and how easy it is for service personnel to fix. It helps engineers make decisions on:
Local Indication: Where to place local displays so they are accessible to operators while still being protected from the process.
Redundancy: When to use multiple transmitters for safety versus single instruments for cost-effectiveness. 5. Official Supplementary Specs (S-718)
The IOGP (International Association of Oil & Gas Producers) provides a Supplementary Specification (S-718) to API RP 551. This is often used by major operators to standardize electronic transmitters specifically for pressure and temperature, adding even stricter requirements for metallurgy and signal conditioning.
