Vibration Module
The Frequensea Decommissioning Tool has completed factory acceptance testing at steel construction specialist J. van Belzen. Functional and watertightness tests confirmed the tool’s performance and integrity.
The vibration module has now been delivered to Deltares, where the next phase of the qualification programme is about to begin.
The vibration module will undergo a series of sweep tests under controlled laboratory conditions. During these tests, the assembly will be submerged beneath a layer of sand in a dedicated test basin, replicating subsea burial conditions.
By gradually varying the operating frequency of the vibration motors, the test team will determine the optimum frequency at which soil liquefaction occurs. These results will form the basis for the entire testing programme at Deltares this summer.
Once qualified, the Frequensea Decommissioning Tool will utilise its patented vibration-induced fluidisation technology to provide the offshore industry with an efficient, environmentally responsible solution for removing redundant subsea cables and pipelines.
By minimising disturbance to the surrounding seabed, this technology will support the growing need for sustainable offshore decommissioning.
