Vopak Singapore: Online Tank Inspection Deployment

This inspection was Asia’s first online/no man entry inspection of a low flashpoint (ATEX zone 0) product tank. With this also being Vopak’s first time, it was imperative that Intero maintained a solid collaboration between ourselves, the product owner and local authorities.

Baltic Connector – Pre-Commissioning

We were requested to perform the pre-commissioning activities for a major offshore pipelay and subsea construction company of the offshore part of the Baltic Connector pipeline. This newly constructed pipeline starts in Inkoo, Finland and ends in Paldiski, Estonia.

Offshore: Unpiggable Flare Line Inspection

A client in the Middle East contacted Intero Integrity Services to clean and inspect a 48-year-old non-piggable 30” gas flare line offshore. The pipeline has never been pigged since it’s commissioning in 1971. A customized solution was required to make this challenging pipeline piggable, cleaned and inspected with high resolution ultrasound before handing it back to operations.

Pitting detection during furnace inspection

Furnace tubes in heaters are inspected during turn-arounds to determine their condition in order to decide for replacement or repair. Degradation in most situations is limited to general corrosion but in rare cases pitting like corrosion can occur. Detection and sizing of general corrosion is a usual capability of furnace inspection tools based on ultrasound technology. However, detection of pitting corrosion requires high resolution ultrasonic inspection equipment, advanced data analysis capabilities and highly experienced alert data analysts.

Offshore pipeline de- & recommissioning

Intero was requested to support an exploration and production company with a Pipeline abandonment and re-direction project. Decommissioning and recommissioning a pipeline safely and cost effectively through cleaning and flooding operations with establish hydrocarbon levels of less than 30 ppm discharged from the pipeline.

Deep Water Unpiggable Pipeline Inspection

A Subsea Operator needed Inline Inspection (ILI) services for a subsea pipeline that had no history of mechanical/intelligent pigging. The probability risk-factor of a mechanical/intelligent tool becoming stuck or immobile in the pipeline was significant.

Pipeline inspection services

Intero Industrial Services’ versatile Piglet® system is aimed at inspecting non-piggable pipelines. Unpiggable features are often found in shorterlength transfer pipelines. Dual diameter, mitered bends, full-bore unbarred tee pieces, and single entry configurations are well within the capabilities of our system and can be inspected utilizing regular, high, and ultra-high resolutions. Combined with highly-experienced field crews, an effective integrated solution is available to ensure the integrity of previously non-piggable pipelines.

Furnace inspection services

Regular cleaning and inspection of your furnace increases its reliability and continuity. Knowing the remaining wall thickness of the tubes can also lengthen the lifecycle of the furnace tubes and prevent unwanted shutdowns. Intero has designed an intelligent, free-swimming tool that is capable of inspecting tubes and bends of your furnace, with a minimum impact on shutdown time.

Cost-effective Ultrasonic Inspection of Large Diameter Pipelines: Technology Update - PTC 2020

Over the past years, the R&D team has worked on the development of a Large Diameter Phased Array tool. The objective of this tool is to obtain better inspection results on Large Diameter pipelines. After a rigorous development project, which consisted of concept design, system simulations, engineering, prototyping and testing, we have executed some pilot projects with 2 different customers. All the results of these activities have been evaluated and summarized in several papers and publications. We have presented these results at the PPIM conference in Houston. It was planned to be presented at PTC in Berlin as well, however, this was unfortunately cancelled due to Covid-19.

Offshore inspection Cases by Intero Integrity Riopipeline 2019

Offshore pipelines are often very challenging pipelines to manage, though certainly not less critical than their onshore counterparts. Small leakages can cause environmental consequences significantly larger than similar situations onshore, while at the same time interventions offshore are a lot more difficult to undertake.

Advantages of Safe In-Service Tank Inspection - 1st World Conference for Inspection & Maintenance Robotics

Utilizing robotics to provide in-service tank inspection has many benefits for the client. A primary benefit is the elimination of risks associated with having personnel enter the confined space while conducting the tank inspection. Another important benefit is the time/cost savings for a client. Robotic inspections for tanks can be completed with the tank full of product. A robotic inspection for a tank can often be completed within 1-3 days.

Overcoming Corrosion Integrity Management Challenges for Storage Tanks and Associated Pipelines

Managing corrosion integrity for tanks and associated pipelines is a challenging and costly endeavor. In order to inspect tank floors, the tank's hydrocarbons or chemicals are usually emptied from the tank causing the tank to be out-of-service for an extended period of time. In addition to the monetary costs there is also a significantly increased safety risk.

A Turnkey Project for a Difficult to Inspect Pipelines - Suncor and Unpiggable 2019

The definition of unpiggable pipelines has been discussed numerous times in the industry in technical papers and presentation. Despite this fact, there remains controversy on what is an unpiggable pipeline. As has been noted in the past by the Pipeline Research Council International (PRCI), pipelines are in fact largely “piggable” today. For this reason, the term “Difficult to Inspect” is now widely used. However, it would be remiss to not mention that pipelines are modified daily in order to accommodate an inspection vehicle.

How can one, as a pipeline operator, ensure that pipelines securely contain their contents at all times?

Pipelines are used to transport large volumes of fluids, some of which are hazardous to people and the environment. Alongside their operational responsibility, the pipeline operators must guarantee public safety. As the global media has evolved over the years, even the smallest incident can lead to massive reputational damage. How can one, as a pipeline operator, ensure that pipelines securely contain their contents at all times?

Dutch - Pijpleidingen: Go with the Flow

Pijpleidingen zijn voor de Rotterdamse haven wat bloedvaten zijn voor het lichaam: belangrijke transportleidingen, zonder welke er geen leven mogelijk is. En terwijl bloedvaten zorgen voor de aanvoer van voedingsstoffen voor de cellen en de afvoer van afvalstoffen, zorgen de pijpleidingen voor het transport van (ruwe) olie, olieproducten, gas en chemicalien. Niet alleen tussen de bedrijven in de haven onderling, maar ook ver het achterland in, naar bestemmingen in Nederland, Belgie en Duitsland.
