English to Russian Tech/Engineering Petroleum Eng/Sci Морские подводные трубопроводы

Текст посвящен методам и инструментам проверки и обследования состояния морских подводных трубопроводов.
Один из инструментов называется stabbing, который имеет двоякое толкование

Вот выдержка из текста:

Stabbing - 1) Stabbing consists of physically penetrating a pole through the soil to measure the pipeline cover-height.
2) recordings of anode potentials and pipe protections potentials is sometimes carried out by contacting the anode or pipe surface by some spike arrangement connected to a reference electrode via a voltmeter. Such potential recordings are often referred to as "stabbings". The recordings are applicable to demonstrate that anodes are "active"; i.e. that the anode potential is not less negative than the design value, and that the protection potential is more negative than the design protective potential.

Как переводится stabbing в первом и во втором случаях?
