A method and system for attaching a TLP to its tendons using pull-down lines to rapidly submerge the hull to installation draft while compensating for inherent hull instability during submergence and to provide motion arrest and aid in station keeping. Two independent comb structures, incorporating suspended polysilicon interdigitated fingers, are fabricated simultaneously on a substrate that can displace independently of each other while attached to a substrate undergoing bending or axial deformation. A can hermetically closes two opening portions of the chassis. The first vacuum box is connected with the vacuum source so that the a degree of vacuum in the first vacuum box is set to a predetermined value.
