The biggest change is the switch from a moored system to a drifting system; catching the plastic by acting like plastic. We learned this has many advantages: higher plastic capture efficiency; reduced deployment- and maintenance costs; reduced risk of system damage due to lower forces from wind, waves and currents to name a few.
From System 001, we learned that connecting the screen to the floater with a dovetail was not ideal for structural integrity. The knowledge gained from System 001 was implemented into a redesign: System 001/B, a smaller, modular version, that could be adjusted offshore, if necessary. During the deployment of System 001/B, we also learned that slowing down the system (versus speeding it up) created the most consistent speed difference between the system and the plastic, allowing the plastic to concentrate and remain inside the system.
