RUSCH: your crane partner offshore… and this is why!

20 December 2021

Offshore cranes of all brands and types are in the heads and computer systems of Rusch. As well as 30 years of experience and know-how. So whatever a crane needs, this company knows how to answer to that. Crane specific and client specific!

Who is Rusch?
Rusch is an independent maintenance and service company based in the Netherlands. Rusch technicians and their specialist equipment are available 24/7. Once on a platform, rig or ship, they carry out tests, do inspections and reparations and solve technical failures. Both planned and acute. Within the time frame and budget and without incidents.

Crane care with a +
But ‘crane care’ entails more at Rusch. Roy Harting, managing director: “In one visit we can do the inspection, repair, maintenance & certification of both the offshore crane and lifting gear such as chains, slings and shackles. This saves clients in travelling expenses. And it gives them the benefit of having one supplier who is responsible for all lifting equipment. It also helps them in avoiding overrunning certification dates, as well as having all certifications in one database for a quick overview.”

Fit for the job
With seven cranes on several rigs and platforms in the North Sea, Dutch TAQA Energy needed an expert to keep machine and gear up-to-date. Hugo Korsman, maintenance manager at TAQA Energy: ‘Our cranes lift equipment and other goods from supply boats to our platforms and vice versa. They are important for smooth logistics on our platforms.”

Since 2006 Rusch technicians do maintenance, repair and inspection on the TAQA platforms. The latest sometimes leads to bigger projects to keep the cranes ‘fit for the job’. This is when Rusch’ expertise in boom repair comes in. As well as the ability to organize the logistic side of projects like these.

From onshore to offshore
What to do when an offshore crane is down for boom exchange? Using a 28meter high and 25meter length tower crane for hoisting goods around the platform? How? Well, by using a 5000 kg foundation frame of 5 by 6 meters to handle the forces of the tower crane to the platform construction. Plus 14 concrete blocks weighing 4100kg each as the counterweight of this onshore tower crane. Rusch did the transport of all the containers and arranged the needed tools and lifting equipment. They demounted the old crane boom and installed the new crane boom. An overload test of the crane was executed under the auspices of Lloyds Register. After that and some Eddy Current investigations Lloyds Register certified the crane.

Boom extension
Another project entailed refurbishing and extending a boom for a 15 ton offshore crane. For a boom extension it is very important to have the construction in a perfect alignment. To execute this the proper way the know-how and experience of crane boom experts with this kind of work is needed. In close cooperation with TAQA and under supervision of Lloyds Register Rusch started the process. First of all by providing a detailed description of the work process and the welding processes. After approval the project started in collaboration and under supervision of Lloyds. Only certified steel and welders were involved and both the welds in the boom lacings related to the boom extension and the existing welds were checked by an independent parties. Hugo: “We are very satisfied with the work Rusch delivers.”

Unique offshore cranes
It is this kind of crane specific and client specific work Rusch wants to do. Roy: “Offshore cranes are not a serial product and often tailor made for client and location. So when we are asked to inspect a crane for example, our work preparation department prepares a specific inspection report for that particular crane. Consisting of the manufacturer’s manuals, the historic information, requirements of the crane owner and from the Notifying body, experience from clients representatives and our own experience. Because every offshore crane is unique and should be dealt with that way in order to keep it running safely for as long as possible.”
