Yes, based on industry standards and regulations, the 42-inch diameter pipeline installed in the Gulf of Mexico in 1978 (often referred to as the UTOS line, which later became associated with Enbridge) was equipped with a cathodic protection (CP) system.

Corrosion Protection Standards: Offshore pipelines in the Gulf of Mexico, especially large-diameter lines installed in the 1970s, have historically used external coatings (like coal tar or, by 1978, often fusion-bonded epoxy) supplemented by cathodic protection, such as zinc or aluminum bracelet anodes.

System Type: During that era, such pipelines typically utilized cathodic protection to manage external corrosion on subsea pipelines.

Regulatory Requirement: The use of cathodic protection on steel pipelines is a standard safety measure required to prevent corrosion.

Operational Context: The 42-inch pipeline (formerly the UTOS line) was built in 1978 to gather natural gas from offshore platforms.
While specific maintenance records for that exact year are not provided in the search results, it was standard practice for such infrastructure to use CP systems for corrosion prevention, as confirmed for that era and for later, similar projects.

Enbridge appears to be one of the industry leaders so I imagine they constructed their pipelines using the best available technology at the time.
