Tom, Richard, and Dave Guertin of LIS had a marathon conference call today with Denis and Matt from AAM. It included a l-o-n-g discussion about wiring.
The vessel’s power and control cables and the wiring for the communications and computer systems will be housed in separate raceways. AAM needs to know by mid-May which cables are computer-related (so they can keep them separate from power and control cables), which cables are considered “permanent” and which can be replaced relatively quickly, how much all our technology-related equipment weighs, and where we intend to put it. AAM also wants a simplified sketch showing where we want the computer-cable raceways and how we’d prefer to route cables to the workstations and other devices on the vessel.
AAM wants all technology-related equipment on site by June 1. If everything goes according to schedule, LIS will be able to start installing technology-related cabling in late October and have everything hooked up and tested by mid-December. This schedule fits the timeframe planned for sea trials, which will enable us to test much of the scientific equipment while LIS is still on site.
Chris Goodrich will provide a schematic diagram showing how the “clean” AC power should be distributed. This design will be incorporated with the wiring designs for “dirty” AC power and systems control. Chris will also work with LIS, Tom, and Richard to provide a basic schematic for lights and outlets.
Several visits to AAM are planned or projected. Two are definite. The first, sometime between June 26-30, will coincide with near-completion of the hull and possibly with flipping the hull to an upright position. With luck, the cabin will be complete, too. Tom, Richard, Dave, and Chris should be there; Mark Gleason may also be able to come. The second visit, on August 15-16, will come at the end of my research in the volcanic regions of the northwest, so I’ll be there, with the same crew. Most systems installations will have been completed by then.
At least five other trips are planned—to make final decisions about interior and exterior details, to launch the vessel and test systems, to attend USCG inspection, and for sea trials—but the exact dates will depend on whether construction stays on schedule. So far, so good!
The architectural drawings were the one unpleasant surprise. Although they aren’t explicitly mentioned in our contract with AAM, we thought that they would become the College’s property—but they’re proprietary! AAM has provided architectural drawings on a few occasions (for example, for NOAA). If the College wants the drawings of this vessel, the architect will probably require a non-disclosure statement.
