ROSEN Group

ROSEN Group is a global technology company headquartered in Stans that specializes in the research, development, production, operation of inspection devices for pipelines and other complex technical systems. It offers its services and products to the oil and gas industry and other sectors.[5]

In November 2023, the former family business was acquired by Partners Group for an undisclosed amount.

History

Beginnings

After completing his studies of measurement and control technology, Hermann Rosen founded an engineering company in Lingen (Ems) in the mid-1970s.[6] Initially he worked with devices and services related to measuring technology for the agricultural sector, among other things.

Present situation

Business Segments

The group, led by CEO Andreas Opfermann, divides its business into four areas:[19]

The Oil and Gas division is responsible for pipeline inspections worldwide. In addition to pipelines, the group also inspects other industrial facilities and systems such as tank farms and pressure vessels, refineries, and spiral pipes.
The Future Fuel business area focuses on ensuring a sustainable, reliable, and affordable energy supply in line with the global energy transition. The expansion of the transport of renewable and low-carbon gases such as hydrogen, carbon dioxide, and ammonia aims to create a decarbonized and integrated energy system. The Group supports plant operators in repurposing their facilities by contributing its experience in inspecting pipelines that transport various media and its data pool.
The Mining business unit is dedicated to the proactive maintenance and inspection of slurry pipelines. This includes industrial plants and maintenance equipment that are exposed to the special challenges of the mining industry. The plants are inspected inline and technically evaluated, particularly with regard to weak points and hazardous areas.
In the Offshore business unit, the group focuses its services on offshore plants with their pipelines, distributors, processing plants, etc.

Equipment and data

Inspection devices, e.g. “pigs”, are used in all business areas. They are developed and manufactured in-house. According to the company, their vertical range of manufacture is between 85[4] and 90 percent.[20]

The large amounts of data collected during inspections are processed, analyzed, and made available to customers for decision-making purposes. The services include inspection, diagnosis and the development of programs for maintenance and repair planning as well as for the integrity of technical equipment and systems.[21]

Locations

According to its own information, the group has over 40 locations in North, Central, and South America, Europe, Asia, and Australia,[22] it operates in more than 110 countries.[23]
