At this point , the team members will start to hook up the ROV system following these steps :
1 . Connect all the cables from the generator and vessel supply to the control cabin and the HPU . Note that there will always be two power inputs for contingencies .
2 . Connect all the cables from the control cabin to the umbilical winch and the LARS .
3 . Connect the umbilical terminal and all hard and FO cables to the ROV . Connect the umbilical docking device and lift the wire onto the ROV .
4 . Connect all hydraulic hoses from the HPU to the winch and the LARS .
5 . Inspect and ensure that all connections are tight . 6 . Fire up the ROV and fill up a checklist . 7 . At the same time , the water bag load test should be done on the LARS .

On the last day of the base team trip , the ROV crews should already be onboard the vessel / oil rig . Once all the ROV systems have been tested completely , the ROV is handed over to the offshore crew and the base team returns to the office . Before the vessel sails , the offshore crew demonstrates to the client that the ROV is in a fully working condition .
The ROV supervisor will start logging all data from the first day they arrive onboard . These are the reports that must be submitted to the office for record and billing :
1 . Mobilisation checklist – to confirm the report prepared by the base team .
2 . Daily progress reports ( DPR ). a . Name of ROV team members onboard , b . Daily and cumulative activities , c . Breakdown of 24 hour operations , d . Spares required , e . Equipment movement , and f . Planned operation for the next 24 hours .
