ROV Surveys

OSC can provide a wide array of ROV services for a variety of sectors.

Remotely Operated Vehicles (ROVs) are tethered, unmanned, submersible devices used for a wide range of activities, including underwater General Visual Inspection (GVI) of offshore structures, such as hydrocarbon production platforms, drilling rigs, windfarms, bridges, and turbines. Uses range from intervention, maintenance, repair, retrieval of lost assets, Explosive Ordinance Disposal (EOD), and surveys for scientific or decommissioning purposes for a range of sectors, including the military.

OSC’S ROV

OSC owns and operates highly versatile and manoeuvrable SeaBotix LBV300-5 Observation Class ROVs (OCROVs). Owing to this model’s small yet powerful nature, the SeaBotix ROV plays both primary and supporting roles for initial pre-diver deployment assessment, as well as dive-supporting activities. The specification sheet can be downloaded here.

OSC’s SeaBotix LBV300-5 ROV systems comprise:

  • 720p colour camera with vertical-camera-tilt function;
  • Multibeam Gemini multibeam sonar;
  • Three-function manipulator; 
  • Two exterior and one interior Light-emitting Diode (LED) light; 
  • Five thrusters for ease of manoeuvrability;
  • All-in-one topside;
  • 150-m robust tether and reel; and,
  • Quick recovery lock latch system.

PRE-DEPLOYMENT ROV SERVICE, INSPECTION, & MOBILISATION

Unlike our competitors, OSC’s ROV systems are maintained to the highest standard and all components are fully functional before deployment to the field. All components are supplied in robust flight travel cases, rendering the ROV simple to transport and rapid to deploy/recover, thus minimising down-time. Mobilisation costs of OSC’s ROVs are low compared to larger ROV units, as the equipment can be carried by hand to the operation site. OSC’s ROV survey team are fully insured, trained, and highly experienced full time employees (not contractors), with the ability to mobilise at short notice.

ROV SERVICES

OSC can provide a wide array of ROV services for a variety of sectors, including, inter alia:

  • Inland security (e.g. structural integrity checks on harbours, docks, ship hulls); 
  • Fisheries and aquaculture (e.g. fish-cage and mooring-integrity inspections);
  • Military (e.g. inspection/security tasks);
  • Diver-support operations (e.g. diver security, mobile lighting); and,
  • Scientific research (e.g. industrial/governmental sensor and video data collection).

POST-PROJECT (ANALYSIS) SERVICES

OSC additionally offers post-project services, which can include image (data) analysis, data interpretation, and reporting depending on client requirements. OSC’s scientists have published a range of ROV peer-reviewed papers on analysis of varied topics including marine mammals, enhancing ROVs for scientific use, progressive colonisation of new production platforms before and after placement, and assessment of older platforms for derogation purposes.
