Drilling has begun! Of course, it didn’t “just happen”—lots of hard work went into getting all the necessary pieces to come together. The previous week’s readiness review had identified a number of critical action items to address before actual drilling could begin. Once resolved, drill preparations began. The drill team routed hot pressurized water through the supply hose and tested it. The drill weight stack was assembled, and the drill head was connected and positioned. Meanwhile, the installation team worked on swapping in the main cable assembly and enlarging a pit that will be used to store excess cable slack after deployment.
