ONE-Dyas chooses LiMain remote maintenance

The Dutch company ONE-Dyas will install the first electrified gas production platform in the North Sea, which will run entirely on offshore wind power. The N05-A project is part of the so-called GEMS area, an area approximately 20 to 80 kilometres north of the Ems estuary. The N05-A platform will run entirely on renewable energy from the nearby Riffgat Offshore Wind Farm, which reduces the emissions to near zero. This project makes an active contribution to the energy transition and to achieving the EU goals of the climate Agreement, in a safe and responsible manner. It increases the security of the local supply of energy and contributes to the local economy.

ONE-Dyas will build a gas production platform, which will be equipped with a latest-generation Liebherr Ram Luffing Offshore Crane RL 2600. For the customer ONE-Days it was essential that the maintenance intervals of the crane did not negatively affect the maintenance concept of the platform. To avoid additional manned days, ONE-Dyas opted for Liebherr and the innovative service concept Liebherr Intelligent Maintenance, in short LiMain.

Minimise maintenance effort

Michel Mens, Lead Engineer E/I and Rotating Equipment at ONE-Dyas, explains: “We have made a strategic decision to purchase the RL 2600 in combination with LiMain’s innovative remote maintenance concept. Our aim is to minimise the maintenance effort significantly, but at the same time to ensure a service life of the crane of more than 20 years. With LiMain’s Module 4, Liebherr offers a solution that is unique on the market and precisely tailored to our crane, the RL 2600. The ability to operate the crane remotely helps to monitor the crane’s performance and prevents unforeseen issues during the maintenance visits.”

Liebherr Intelligent Maintenance

With LiMain, maintenance can be carried out remotely, from land. Manned service visits on site at the crane can thus be reduced to a minimum. This way of performing service with LiMain is contemporary because it reduces costs, protects the environment by significantly reducing travel expenses, and at the same time ensures a long and sustainable use of the unit. Maintenance independent of time and place is possible. Platform operators can choose from various modules and so determine the degree of autonomy and scope of intelligent maintenance for the crane. After delivery and assembly, the platform operator can subsequently monitor and maintain the entire offshore crane fleet from the office.

“The cooperation with ONE-Dyas so far has been highly professional and we look forward to a future partnership. The customer has recognised the tremendous benefits that LiMain offers platform operators in reducing operational costs. In addition, with its low height and small footprint, the ordered RL 2600 is the ideal crane for such platforms,” says Stefan Schneider, Global Application Manager General Purpose Offshore Cranes.

The latest generation of the RL 2600

The particularly weight-optimized and compact design is the characteristic feature of the RL series. On both fixed and floating offshore installations, especially in the wind power industry and in the oil and gas sector, RL cranes are mainly used for maintenance and supply work.

Based on customer feedback, Liebherr optimised the RL to become the most compact maintenance crane. This results in a reduced construction height and a small tail radius. The elimination of a machinery house allows the crane to operate in confined space conditions and environments. Additionally, the crane can be ex-certified (ATEX and IECEx).
