18 PHASE 1 & 2 1. Establish DP position above MONTEBELLO Confirm DP station keeping and suitability for ROV Operations 2. Confirm surface positioning and navigation equipment operating and quality of data supports ROV operation Surveyors document position and station keeping Surveyors confirm all geophysical positioning equipment operational given site conditions

19 PHASE 3 Launch ROV/ Calibrate USBL System Place USBLbeacon on bottom Calibrate shipboard USBL positioning equipment Calibrate ROV positioning though the water column

20 PHASE 4 ROV Video Survey / General Condition Assessment Conduct Systematic ROV Flight Over and Around Wreck ID Hazards Utilizing Video and Mesotech MS-1000 Sonar Imaging

21 PHASE 5 Hull Cleaning Operations ROVDeployed Barnacle Busters & Wire Cup Brushes

22 PHASE 5 Hull Cleaning

23 PHASE 6 Ultrasonic Hull Thickness Gauging Cygnus Ultrasonic Thickness Gauge - The probe does not need to touch the hull Measurements can be taken through 5 mm of water Readings are not influenced by the probe orientation

24 PHASE 7 Sediment Samples 4 Samples Recovered 2 Each Port and Starboard

25 Sediment Samples PHASE 7

26 PHASE 7

27 Neutron Backscatter Methodology used in refineries and smelting plants Radiation Source Fast Neutron Emission Collision with similar sized atoms reduce Neutrons to Thermal Nuetrons The more unknowns, the more chance for error

28 PHASE 8 Neutron Backscatter - Calibration Box 2 Compartment Steel Box Bottom Compartment Crude Top Compartment Open to the sea

29 PHASE 8 Neutron Backscatter Tool Deployment Tool Skid Mounted Nuclear Source Installed

30 PHASE 8

31 PHASE 8

32 PHASE 9 Physical Content Assessment Drilling Tool Skid Mounted DSSTool

33 Verification of Theoretical Results Different in deeper water when not using divers

34 PHASE 10 Hull Coupon Sample Collection 7 Samples Were Obtained Utilized for Corrosion Analysis

Will attempt to remove when other tanks are cleaned/tested in order to safeguard the ROV from entanglements. Multiple hull anomalies (old) discovered in Summer Fuel. Presumed empty. No oil discharge observed. Sediment Samples (Pending Debris / Hazards) will be taken 5 ' from the hull each side even with the break of the bow from the torpedo damage. That places the starboard side 24' ahead of the forward bulkhead of Cargo tank 1, and the Port side will be roughly 12 ' aft of that point. The stern locations are even with the aft bulkhead of the FO tanks, 5 feet out from the hull. Numbers represent hull thickness from UT gauging (inches). S.S.
