Fugro, the global geo-data specialist, has awarded a contract to Bosch Rexroth to fully maintain and further improve Fugro Synergy’s hydraulic equipment.
Fugro has worked with Bosch Rexroth for over a decade to ensure it has the best hydraulic systems and software solutions on board its geotechnical drilling vessel, the Fugro Synergy. Now, they are working together again in order to better prepare for the future.
The Fugro Synergy vessel has been in operation since 2009, and is primarily used to drill into the seabed in order to analyse whether it can be safely used as a foundation for structures like wind farms or oil rigs. This ship was built to be effective in the harshest conditions, and Bosch Rexroth provides the drives and controls for operating under these circumstances.
During the operation, motion compensation of the vessel at sea is one of the drive and control challenges we faced. Two long stroke Heave Motion Compensator cylinders in combination with a compensating accumulator and intelligent software ensures that the drilling operation remains steady and accurate even when waves increase in size.
As the ship has been operational for ten years, a full service of the hydraulics system and associated software is required. It has been performing reliably for the entire time, so the main focus of the service and maintenance is to ensure another decade of smooth operation. However, as the vessel is in dry-dock, this presents a great opportunity to look at ways to improve the system even further.
“A full recertification process is necessary every ten years, and this is to ensure that the vessel continues to comply with the DNV GL standards,” says Mark Timmermans, Account Manager at Bosch Rexroth. “Fugro then asked us what we would recommend for the hydraulics system going into the future. Generally speaking, they want another ten years of smooth operation, improve up-time, and more specifically asked for some alterations to improve the existing setup.”
An overhaul and exchange program for the main hydraulic pumps is in place as part of planned maintenance, and all these activities require good cooperation of the Boxtel service shop and service technicians on board.
Fugro also requested that Bosch Rexroth look into a way to fix the level of noise coming from some parts of the ship, along the main hydraulic pressure lines. So, as part of the overall maintenance, Bosch Rexroth are implementing a solution.
