Rostock (Germany), September 2023 – The oil and gas sector is undergoing a transformation. The development of gas resources from subsea gas fields is helping to meet the growing global demand for natural gas. With the construction of floating facilities for the extraction, liquefaction and storage of natural gas, the demand for compact cranes is also increasing. Since its establishment in 2012, Wison has become the leading company in China in the field of floating natural gas applications.
The RL series offshore cranes have convinced the sole service provider for natural gas monetisation solutions in China. All cranes of the series in the portfolio will support the FLNG unit in maintenance and supply work, “The fact that we convince Wison with the entire RL series is both a success and an incentive for Liebherr to continue to align the offshore portfolio with the needs of the market and its customers,” says Stefan Schneider, Global Application Manager for General Purpose Offshore Cranes. “The cooperation with our contract and service partners from Liebherr China Co. (LMS China) was a particularly important factor in finalizing the contract. They will support the process during the construction of the FLNG. After commissioning, a field office responsible for the Republic of Congo will take over,” Schneider adds.
Optimal design enables reliable and flexible crane control
The compact and weight-optimized crane construction of the Liebherr RL series offers the possibility of being used in the best possible way, even when space is limited, thanks to a well-thought-out design. This is illustrated by an optimised overall height, a small tail radius and the absence of a machinery house. The cranes also offer advantages for its operators. The redesigned 7 m³ large cabin is ergonomic and ensures low-fatigue working. Its modern equipment with an excellent surrounded visibility, the new driver’s seat in combination with the new operating concept including new controls and revised air conditioning ensures safe crane operation. “Equipping the FLNG with the RL series creates a holistic value. Highest safety standards and state-of-the-art working conditions enable increased working capacity. For us, working with Liebherr means having a global crane manufacturer at our side whose expertise sets global standards,” comments Mr. Zhang Shouyue, Deputy General Manager of Project Management Office from Wison about the cooperation.
Worldwide network enables reliable customer service
The new floating plant can store over 180,000 m³ of liquefied natural gas and 45,000 m³ of liquefied petroleum gas. The cranes installed on the platform are part of an integrated service structure. The worldwide Liebherr network of experienced engineers makes it possible to supply spare parts and to offer the best possible service within the shortest possible time, so that productivity of the plant can be ensured. “The modular design concept of the main components of the Liebherr RL series is an exciting aspect and the increased interchangeability of the components once again comes to the fore,” says Yang Dong, Liebherr China Co.
The RL crane series impresses with further special features. The innovative cabinet inside the slewing column, which houses the world’s first explosion-protected Ex d cabinet that safely dissipates explosion pressure. „EXpressure“ was developed by Liebherr partner R. Stahl AG. Also available for the RL series is LiMain, the fully digital, remote-controlled and semi-automated maintenance system. Its modularity with individual packages allows the user future maintenance independent of time, place, and resources.
