2. Newport BEP prep □ Confirm BEP Readiness and Integration Checklist has been completed □ Verify that lid eyebolts are removed (place in cruise bin with dummy plugs) □ Remove Optode (DOSTA) Cap before opening and locking doors in place □ Remove dust cover bags from copper tubing inlets for OPTAA (ACS) and CTD □ Lock BEP doors in open position □ Check that ROPOS team approves locking bumpers and hydrophone frame

position if first deployment or there have been changes in this setup □ Mount cable horns on first deployment □ Mount oil-filled ROV mateable 50m cable on to cable horns; attach strain

relief yale grip; and add break away twine to cable when mounted (first deployment only)

□ Attach bungee rings to hold cable on horns. (First deployment only; Have ROPOS check bungee set up)

3. Loading BEP onto Ship □ Lift BEP from center point, leave air rides attached (Dry wt. = 3,200 lbs.; Wet

wt. = 2,100 lbs with oil filled cable and hydrophone) □ Find out preferred location and orientation on deck for ROPOS

4. Pre-Deployment (At Sea) – use DEPLOYMENT CHECKLIST, On Deck section □ Apply Desitin to ADCP and VEL3D transducers □ Remove CTDBP pump inlet covering (cellophane over copper tubing) and

verify that inlets are exposed for both CTDBP and OPTAA (ACS) □ Cut cable ties on hydrophone cap (x2) □ Remove PHSEN water bag and store □ Draw diagram with relative position of ADCP North and Vector X axis to BEP

“Forward” 5. Connect BEP to ROPOS – use DEPLOYMENT CHECKLIST, ROPOS section □ Pick up BEP and move to ROPOS area (Dry wt. = 3,200 lbs.; Wet wt. = 2,100

lbs with oil filled cable and hydrophone) □ Connect to ROPOS (see Fig. 1) □ Photos/video of ROPOS docked to BEP and deployment into water

6. Deployment (separation from ROPOS) use DEPLOYMENT CHECKLIST, Seafloor section □ Place BEP at deployment site

o Orient cable side towards LV Node o Capture orientation information for BEP (esp. heading), use

orientation diagram o Detach from ROPOS

□ Connection to LV Node

o Remove restraints on 50m cable using rope handles o While holding free WetMate, ROPOS backs away at 10° angle from

bottom o Attach WetMate cable to LV node o Return to BEP

□ Deployment of Hydrophone Frame o Approach BEP at FWD STB corner o Pull bungee pin restraint on HYDRO cable (help fall away if needed) o Pull bungee pin restraint for HYDRO frame to BEP o Right manipulator hand (RH) holds HYDRO handle "A" while left

manipulator hand (LH) grasps BEP Capture Bar Handle (see Fig. 2) o Capture Bar Handle is moved up, thus allowing HYDRO to rotate (see

Fig. 3, top) o LH grasps HYDRO handle "B" o Lift HYDRO up and away from BEP (see Fig. 3, bottom) o Back away from BEP slowly and stop before cable is taut (see Fig. 4) o Place HYDRO on bottom o Remove (turn and lift) protective cap and place in ROPOS basket (see

Fig. 5) o Return to BEP

□ Remove and stow cable horns (see Fig. 6) □ Unlock and close doors (see Fig. 7) □ Collect position and oceanographic information from ROPOS

7. Startup from Shore Station (Linda in Seattle) □ Follow startup sequence spreadsheet

8. Recovery □ Ensure that hydrophone protective cap and cable horns are secure in ROV

basket prior to ending dive 9. Unloading and return to Corvallis □ Recover air ride supports □ Bring back hydrophone protective cap and cable horns □ Remember all dummy plugs and protective covers

Figure 1. ROPOS attached to BEP. Note position of 50m extension cable on horns on Port side, and hydrophone stand attached to Forward end.

Figure 2. Close-up of hydrophone stand attached to Forward end of BEP. The upper taped grab area is labeled A and the lower grab handle is labeled B

Figure 3. Illustration of ROPOS removing the hydrophone stand from the BEP. Grab area A is grasped with the starboard manipulator while the hydrophone frame handle is lifted with the port side manipulator. The stand is then lifted free of the BEP using both manipulators.

Figure 4. Once the hydrophone cable cord restraints have been cut, and the cable has been unspooled, the frame can be moved away from the BEP, about 10 meters.

Stop before the cable goes taut.

Figure 5. The hydrophone cap is removed by turning the cap clockwise and lifting upwards, once the frame is in place. The cap should be placed in the basket of the ROV and recovered after the dive.

Figure 6. How to remove the cable horns from the BEP. Grasp the T-handle (A) and turn clockwise (B). This should loosen the horn (C), and it can be lifted off of the BEP door (D). Once removed, the cable horns should be stowed in the ROV basket and recovered after the dive.

Figure 7. How to close the BEP doors. First, slide the latch mechanism inwards (towards the opening in the BEP), then lift the door towards the ROV. Once past the midway point, the weight of the door should cause it to close by itself.

Camera Deployment Plan 1. Materials List for Camera □ Camera extra hardware □ Power supply □ Rubber tubing for camera cable management □ Zip ties □ Test cable □ Cisco router □ Internet cables □ Laptop with GUI software □ Metric stubby allen wrenches (especially need #3, 5, and 6) □ Metric combo wrench set (especially need 11 mm) □ Large standard wrench set □ Pliers and wire cutters □ Focus plate □ O-ring grease

2. Loading onto Ship □ Transport Camera disassembled to Ship □ Lift Camera lander using strap under central beam

3. Camera Assembly □ Set tripod lander frame to desired height (<53”, height of tool basket) □ Follow Kongsberg Manual to mount camera and yoke onto frame □ Use rubber tubing and zip ties to manage cables so they do not get hung up

on tripod handles and tabs □ Verify full range of motion of camera using software to travel between soft

stops 4. Pre-deployment camera operation and testing on board □ Connect green test cable to camera, power supply and Cisco router □ Power up instrument (takes up to 2 min. to wake up) □ Start up GUI Software

o Go to Set up tab and select fixed address, enter: o Select “Set” button to save (however software will forget next time it

is opened) o Go to File and select Set up to check IP address o Go to File and select Connect

o Ignore prompt that states there is already a connection and press “OK”

o Press “Play”, should see the camera display now o Confirm camera operation by rotating camera between soft stops,

which should be set at approximately 45° and 315°, see manual to reset stops

o Verify tilt of camera up and down (may need to slide tilt power all the way up if it gets stuck at bottom or top); tilt should not be angled more than 60° to avoid capturing feet in image

o Focus camera by manipulating the Zoom, Focus and Iris settings on the Lens tab. An example of a focused setting in lab was:

Zoom = 67 Focus = 21 Iris = 7 Lamp = 39

These settings will change with light and distance. o If Camera image settings become stuck try going to the Pan and Tilt

tab and entering Go To “0” in the preset window, select Go o After camera operation has been verified set the static gateway

address depending on location:
