Delta600P Offshore Tests Done!
In no less than 62 hours of rigorous offshore testing, tech scale-up Seaqualize successfully completed offshore trials for its inline Balanced Heave Compensator (iBHC), the ‘Delta600’. Together with testing partners Van Oord and nautical research institute MARIN, the offshore lifting tool was tested for fixed-to-floating, floating-to-fixed and floating-to-floating transfers of 300mT loads. The Delta600 is DNV certified and ready for work.

Delta600P Harbour tests
In July 2021, we tested the Delta in its new hometown: Rotterdam. Seaqualize held a series of tests, including test loads ranging from 100mT to eventually 660mT for a 110% SWL functional load test.
These tests are what we refer to as ‘inverted’ tests. Instead of holding the load still, we accelerate the load with the maximum speed over the full stroke, to show the tool meets its specifications. This way, even though the crane vessel itself is not heaving, we test if the tool is able to compensates all desired heave motions when they would occur.
Further tests included pick-ups and set-downs.
Video compilations of the full test will be available soon!
Next up: offshore trials, October and November 2021
Delta600p structural test
At the factory location, we tested all welding at a 110% overload pressure, to check the integrity of the welding work. First steps towards offshore certification.
Delta2
prototype tests
We regularly try out new features on the Delta2 prototype we built earlier. It’s built 100% according to the base of design of its full scale brother (The Delta600), currently under construction, just a bit smaller:
2 mT payload
116 cm stroke
Jaguar testing
We thought we’d change our routine from the standard test weight container, to something that better conveys how much we believe in our own product.
Feeder barge supply operations
Using a feeder (supply) barge for offshore installation operations can be hugely beneficial: it can save up to ~30% on your project duration by not needing to shuttle up and down with the installation vessel to the harbor, to get new components.
But how to lift loads from that heaving barge when it comes alongside the installation Jack-up?
In this test, the Delta2 shows it can safely control and automatically pick up a 400kg load from a heaving deck (simulated by an Ampelmann hexapod). No snatch loads, accidental lift offs and re-hits. And importantly: No need to wait for recharges before you can lift the next component: You keep on lifting as long as needed, even for varying weights!
Crane test
The Delta2 balances a 2 mT load while heave is simulated by the crane operator of a land crane, hoisting up and down. The operation requires ~300W of power, not even half a water cooker.
Using a feeder (supply) barge for offshore installation operations can be hugely beneficial: it can save up to ~30% on your project duration by not needing to shuttle up and down with the installation vessel to the harbor, to get new components.
MRU testing
Tests with the Motion Reference Unit (MRU) normally on board the Delta. It shows how quickly the tool responds to any movements made by our engineer, holding the MRU
