MiRO Refinery

Plant shutdown TA 2021

Period: February 2020 – April 2021

Superlatives for the customer and for WWV

For the largest plant shutdown in the history of the Karlsruhe refinery, around two thirds of the production facilities of the Mineraloelraffinerie Oberrhein (MiRO) were taken out of operation for a major inspection. WWV was able to take on the largest units and was the largest contractor on site with the full range of services and at peak times over 1,000 workers. In the midst of the second wave of the corona pandemic and under partly wintry cold conditions, the demanding projects became not only a technical but also a logistical challenge, especially in health management.

WWV, Project, MiRO Turnaround

A real “partner company “

WWV Wärmeverwertung sees itself as a true partner. That means taking responsibility and showing commitment. Thanks to excellent technical and managerial staff and forward-looking resource management, it was thus possible to reliably carry out even major unforeseen work in the short time window of the turnaround. And despite its own extensive scope of services, WWV was on hand to provide support in the event of bottlenecks outside its own area of responsibility.

Wide range of services

In addition to comprehensive maintenance work, WWV was significantly involved in the projects to optimise the refinery’s key facilities. Whether it was prefabricating pipelines, integrating new equipment into the existing plant complex, mechanical works, or extensive repairs to process furnaces or column work – there was no shortage of challenges. After the successful completion of the work, MiRO enters the competition sustainably strengthened with increased conversion capacity for petrol, diesel and chemical intermediates.

Commitment and flexibility

A particular challenge came to light when extensive damage to the pipe system and the pipe support system of the TOP2 furnace was discovered at the beginning of the shutdown. With the help of a convincing repair concept, excellent welders and a high degree of flexibility and commitment, this unexpected critical path was successfully mastered.
