Eric & Corey Early last week the crew completed the Actuator installation at BSC4. *** There is fluid in the Actuators--DO NOT operate the Valves *** The two four-way valves at the top of each BSC SEI Pier must not be adjusted or fluid will escape. There is no locking mechanism. We haven't had any issues with this, just wanted to reiterate. Couple photos: 001 is Actuators installed. 003 is the valves at the top of Pier for reference.
