Rosen has developed a comprehensive asset integrity management solution covering the complete asset life cycle for tank farms. Rosen has developed a highly flexible, modular suite of software tools that includes asset integrity management software (ROAIMS) for tanks. ROAIMS for tanks offers a range of applications that simplify data organization, task planning/scheduling, inspection data management and reporting to meet both internal and external requirements and hence improve asset integrity. The user friendly suite enables easy customization to suit operator needs and straightforward and cost effective implementation of remedial action. ROAIMS for tanks makes the whole inspection, maintenance and repair process transparent and manageable. ROAIMS for tanks provides operators with a single comprehensive database to efficiently integrate and manage information relevant to the safe and economical operation of above ground storage tanks and related infrastructures.

Caused by improper crimping of the steel sheet in the production process, roof topping is a geometric anomaly that occurs along the longitudinal seam weld of the pipe. These incorrectly crimped sheets then result in a deviation from the perfectly circular geometry of the pipeline. The implications of roof topping for pipeline integrity are severe, e.g., risk of failure during hydro-testing or fatigue failure during pipeline operation. A discussion on measuring roof topping effects as an integral part of routine in-line inspections covers the nature of the measurement method; relevant experience gained in the field; and the degree of accuracy achieved with high resolution geometry technology.

The paper discusses the effect of combined requirements on the design of pipeline inspection tools. It is shown how single, usually uncritical, features can become critical in combination. In the presented case study, this was caused by the combination of a high flow rate, the high wall thickness, tight bends (3D) and the presence of a wye-piece. The wall thickness limits the tool velocity to a value to stay within the specifications. To allow full production for the client, a speed control valve is required to reduce the tool speed accordingly. A speed control system is based on a guided flow through the driving module. But because of the long cavity inside the wye-piece, a 3D bend capable pull unit is too short to cover this cavity. Consequently the sealing has to be fully extended on the second unit. Therewith the available design faces the challenge: The bypass through the second unit can flow around the front unit inside the wye. Therefore the bypass has to be guided through the second and the first body into the valve. A new connection concept was designed to meet this requirement. The solution is a universal joint providing a large bypass area to connect the two central bodies for the flow. The tool performed the inspection run successfully and with full function of the speed control system. As a conclusion, it can be stated that even for otherwise standard features and operational conditions, a non-standard solution can be required to meet full specification and convenient run conditions.
