ROV tasks

LARS

The LARS (Launch and Recovery System) is a type of marine-based system that is use to launch and recover equipment such as a remotely operated vehicle. The system consists of a series of winches, wires rope, wire sheaves, hydraulic components and lot of automation that together makes a fully operational system with a major spread in the oil and gas industry.

ROV duties

Remotely vehicle is able to transfer power, data, and control signals between the surface vessel and the subsea equipment. Through these capabilities allow ROV to perform a variety of tasks such as inspection, maintenance, and also repair.

Commissioning jobs can be tricky, just follow and you’ll see how and why…

Furthermore during launch and recovery operations, the ROV is deploy and retrieve using a tether management system (TMS) that is integrate in LARS system. The TMS is responsible for managing the ROV’s umbilical cable, which provides power, communication, and control signals to the ROV.

The cable, often referred to as the umbilical or tether, typically contains multiple components within it.

These components can include electrical conductors for power transmission. Fiber optics for data communication, and other necessary elements for control signal transmission.

Therefore, the cable connected through the docking head to TMS and ROV enables functions of power transfer, data communication, and control signal transmission, allowing the ROV to operate effectively and perform tasks in subsea environments.

The functions perform by the cable are list below:

1. Power Transfer: The cable gives electrical power from the surface vessel to the ROV. This power supply energizes the ROV’s systems, including thrusters, lights, sensors, and other onboard equipment.
2. Data Communication: The cable includes fiber optic strands or other communication channels that facilitate the transmission of data between the ROV and the surface vessel. Real-time video feeds, telemetry data, sensor readings, and other information collect by the ROV is send through these communication channels to operators on the surface.
3. Control Signal Transmission: Control signals and commands from the surface vessel are transmitted through the cable to the remotely vehicle. Remote operators control its movements, operate manipulator arms, and carry out other tasks as needed.
