After tweaking its plastics collecting system over the past four months, The Ocean Cleanup redeployed the revamped System 001/B last week.
“After only four months of design, procurement, and
assembly, the crew is now on their way to the Great Pacific Garbage Patch with
the upgraded System 001/B,” the company informed via social media.
Being towed by the Maersk’s supply vessel Maersk
Transporter, the system is scheduled to arrive at the test site on June 25.
After a couple of years of various tests, the system failed
two months after being deployed and was towed to Hawaii for inspection and
repair. The company earlier explained that the System 001, which was deployed
into the Great Pacific Garbage Patch in September 2018, needed final
fine-tuning before it could start harvesting plastic at full potential.
The Ocean Cleanup confirmed many key assumptions of the
design, but also encountered two unscheduled learning opportunities during the
period – the system did not maintain a sufficient speed, allowing plastic to
exit the system, and a stress concentration caused a fatigue fracture in the
In mid-January 2019, the Wilson system completed its
800-mile journey and arrived in Hilo Bay, Hawaii.
The latest campaign would test the various modifications
that were made to the system.
