MARINE SERVICE
Athantic Oil Services Limited
Unmatched Pipeline Services
In partnership with “xxxx”, we provide a comprehensive set of pipeline services unmatched anywhere in the country. Maintaining the inner cavity of pipelines is essential to the safe and efficient transportation of oil and gas. Eliminate debris and other obstacles preventing the free flow of products through your pipeline using our Pipeline Cleaning and Flushing Service. Our Pipeline Gauging Solution will help locate bore reductions in pipelines preventing the passage of cleaning and inspection tools. External mechanical damage is one of the major causes of pipeline failures. We provide services for the detection, localization and evaluation of the size of dents, ovality, buckles and reductions resulting from external mechanical damage.
We are experienced in the construction of several inches’ pipelines including mainline construction utilizing mechanized or manual welding methods in a variety of geographic terrains encompassing prairie, muskeg, heavily forested and mountainous regions. Our capacity includes mainline spreads of modern pipeline construction equipment.
Athantic Oil Services Limited offers integrated Pipeline Construction & Maintenance Services which covers, fabrication, installation, assembling, hydro-testing, maintenance & repairs. These services are offered on Land, Swamp and offshore terrains. Through purpose driven systems and procedures in place, we promote a culture of safety, strives to perform our services to the highest Quality Standards that is obtainable in the Oil & Gas industry.:
Our pipeline construction scope covers:
Pipeline Installation & Repairs
Pipeline Pigging & Cleaning Services
We offer a complete range of services for high resolution and quality defect identification using Magnetic Flux Leakage (MFL) and Ultrasonic Technology. We partner with world leaders in pig technology to supply and run intelligent pigging tools for pipeline verification.
We retrieve, analyse and report on the pipeline data and provide procedures for repair works where required. Our system contains a horizontally placed transducer contained within the center body of the pig. The transducer sends it sound wave forward where it hits a 45° rotating mirror which then directs the sound wave perpendicular on to the pipe wall. From the inner pipe wall the next signal will travel to the outer pipe wall. Every time the signal hits a surface it will bounce back the same way it came allowing the computer to calculate the time of travel. This time of travel is then converted to distance and measurement exists.
Ultrasonic Testing is not suitable for very thin pipe wall thickness but for all practical purposes this is not relevant for the type of pipelines typically being inspected in the upstream, midstream and downstream oil and gas industries. UT tools work well with the vast majority of pipe wall thicknesses found in the oil and gas industry. As the technique requires a liquid coolant through which the pulse can travel there must be a liquid in the pipeline although by using batching techniques where a liquid slug is sealed between 2 high sealing pigs it is possible to inspect gas pipelines with UT intelligent pigs.
We pride ourselves in our Intelligent Pigging service because of its ability to provide a highly accurate value for local wall thickness whilst being lightweight, small and easy to mobilize. With such high accuracy ultrasonic tools can be used for comparing actual wall thickness with nominal wall thickness, verifying previous inspections, fitness for service evaluations and baseline surveys.
