Synchronous operation and testing of hose reels for the GIANT 2000

The hoses are responsible for transferring the correct hydraulic oil flow and pressure to the dynamic environment where our GIANT operates. The hose reels ensure efficient and safe hose management. Testing these are thus very important for the proper functioning of a vibro hammer. This is why Dieseko Group recently tested four hydraulic hose reels simultaneously for the operation of our GIANT 2000 Vibratory Hammer.

It is crucial that all hose reels work together in perfect synchrony, whether they are paying in or out, and that they are configured as a master-slave system. It should be possible to make individual adjustments without disrupting the synchronization between the hose reels. Additionally, they must be pressure-tight, apply the correct tension, and respond fail-safe in case of emergencies or malfunctions.

Tests were recently conducted on the Giant’s hose reels to test the operational readiness of the hose reel system, in order to prepare for offshore use. The test simulated real project conditions as closely as possible. The reels were positioned in the same way they would be on a vessel, and the hose ends were connected to a spreader bar, which created different pay-out and pay-in angles that would also occur in real operations. Different redundant operation modes were also tested, including remote-controlled, HMI-controlled, and emergency-controlled modes.

The tests were performed with great care and attention to detail, and the equipment has passed with flying colors. This once again demonstrates that Dieseko is a reliable partner for offshore operations.

The tests have shown a hundred percent functionality after hydraulic and software adjustments, and have provided useful insights into safe and efficient operations on board our client’s vessel. We are thrilled to utilize this new equipment in its first offshore campaign in 2024.
