Troubleshooting A Sub-Sea Acoustic System

Troubleshooting a sub-sea acoustic system requires a panic free, patient, systematic

and methodical approach together with an appreciation of the local working

environment. It is important to identify and confirm the requirement to troubleshoot

while also recording all remedial actions. Firstly, the operator must be certain that the

issue is sub-sea having checked the top-side equipment for error, e.g. software issue,

cabling, etc. Secondly, the context of the operation must be considered, e.g. the

occasional acoustic range measurement drop-out maybe be acceptable and not

warrant remedial action. Generally troubleshooting is required where it is confirmed

as a sub-sea issue with prolonged periods of poor or no data and / or

communications.

8. DTU Unit at the Processing Room and for the change battery tools also inside the DTU unit.
9. The LBL transducer is OK now after we change the head with the Calamity Jane. We also change the transducer cable. For the broken cable and intermittent transducer was packed and stored at the bosun store. So you will loose your headache after this.

HANDOVER NOTES – Survey Tech Highland Rover 19 June 2008

1. Survey tech duty is from 0000 – 1200. U can refer to duty roster inside survey room.
2. Sonardyne Fusion – Pole and transducer head was installed. Lower down the pole when you want to use the LBL pole. Ask for assistance from bridge to lower the pole.
3. Audacia and Lorelay sometimes need a Compatt for a reference beacon. Please prepare the Compatt with the sand bag and we will deploy it with assistances of the marine crew.
4. Videotel at Survey Room (on top of rack) near surveyor online. Please switch on when need and switch off when we are not using it, to avoid interference with any vessels in this field.
5. We are using 2 ROV i.e. ROV Q2 & ROV Q4. We have 6 beacons here and the latest Frequency Management we received ask us to use 3 Beacon code only, B38, B58 and B78. Please update the beacon code when we receive any update on the Frequency Management. Update the beacon attached to the ROV to white board.(But for now only Q4 is running good. Q2 still repairing)
6. Charge the beacons in survey room as required.
7. At the moment, ROV is using our beacons for positioning and sometimes they use their own Responders when operating in shallow waters. There is no responder for the both ROVs, both of them are using the transponder.
8. ROV Q2 and ROV Q4 interfacing already done. Details for interfacing can be checked at “ C:\01 INDGH3206- DHIRUBHAI –INDIA\01 Party Chief\05 Logistic\01 Project Equipment List\ Comm Port&Beacon xls ”. At party chief computers.
