Expert perspectives on oil and gas
pipeline matters, trends, and best practices.
As the go-to engineering partner for pipeline operators in the Midwest, HT Engineering is committed to sharing our latest thinking about innovations, regulatory changes, and other critical issues impacting the ways in which pipelines are designed, constructed, operated and maintained.

It was a relatively straightforward redesign of some piping to improve the functionality of a metering and pig launching station. The project included designing a pressure equalization runaround – a one-inch line to divert product around a 16-inch valve to allow refilling of the pig trap. We developed the design to meet regulatory requirements, client standards and operations preferences, and provided the drawings to the client’s construction team. We supported the client during construction, helping to resolve a couple of issues and answering several questions along the way. But the runaround posed no problems.Read the Article
Working across multiple companies, disciplines, and personality types can be a challenge. However, by focusing on clear and consistent communication, actively inviting feedback, building relationships, and documenting team knowledge as outlined above, you can build a high performing team that is up to the challenge – and most of the time, enjoys facing the challenge together.Read the Article
Surge is a potential issue in liquid pipeline operation. It’s relatively rare in a line that’s operating normally, but as we’ll see, there can be serious consequences when it does happen. Fortunately, there are steps that pipeline operators can take to prevent surge from happening, to reduce the magnitude of the surges and to minimize risks and damage from surges.Read the Article
The response to cathodic protection (CP) varies from company to company and manager to manager. Some understand its importance and give it the time and funding it requires to be effective, but others don’t see much value in it at all.Read the Article
Our world is facing a growing need to reduce emissions of planet-warming greenhouse gases. As a result, the pipeline sector is facing increasing regulatory and public pressure to reduce its impacts through unplanned or fugitive emissions. Some pipeline operators also feel regulatory pressure to manage emissions to maintain their air quality permits, which are based partly on the number and type of fittings in a facility.Read the Article
It was supposed to be an uneventful second-round in-line inspection tool run through a liquids pipeline about 100 miles long. But it stopped being ordinary when analysis of the tool run data found 1,800 crack-like features that met burst pressure remediation criteria and were potentially hazardous to the integrity of the line.Read the Article
ILI inspections are essential for meeting regulatory guidelines, and are also essential for an operator to be able to understand threats that may have been previously unknown.Read the Article
Industry events like the recent Pipeline Pigging and Integrity Management (PPIM) conference in Houston are great places to identify trends and understand what the industry will be focusing on in the near future. HT Engineering sent a delegation to and hosted a trade show booth at PPIM 2022.Read the Article
