Offshore Energy Applications
Meridian’s fleet of ROVs track, measure and inspect undersea pipelines, inside and out. Our ROVs handle a variety of pipeline services, including:
- Performing non-destructive testing to measure pipe thickness and corrosion
- Surveying, such as general and close visual inspection of footers and welds
- Echoscope 3D sonar image mapping
A single ROV can inspect kilometers of pipeline a day.
Rig & Platform
Meridian’s easily mobilized fleet of compact ROVs is ideal for performing detailed inspections of the seafloor – before, during, and after rig and platform installation – allowing for advanced evaluations and monitoring of seafloor conditions, critical to any installation.
Our ROVs are also optimal for post-installation inspection, as they permit inspection without halting rig or platform operations. Meridian’s ROVs inspect existing rig risers, jackets, j-tubes, s-tubes and umbilical networks. They are ideal for testing platform anodes, changing out equipment, operating valves and recovering debris – all while the rig remains fully functional.
Wind & Tidal
Offshore wind turbines and other forms of renewable energy including tidal power continue to see increased development. Meridian can deploy its ROVs to perform sea floor inspections before, during and after turbine construction, as well as inspections and maintenance. Wind and tidal turbines are traditionally located where water depths are relatively shallow and winds, tides, currents and waves are of high energy. These factors make traditional monitoring techniques such as divers and camera less effective than sonar or laser imaging performed by ROVs. Both ROVs and AUVs also have the advantage of providing a high level of positional accuracy in areas of shallow water and heavy currents.
ROVs with high definition cameras can perform the valuable task of directly observing and recording pipeline touchdown points (TDP) in real time. The ability to identify obstacles before and during the pipe laying process and confirm the pipe is in good condition prior to its installation on the sea floor helps avoid costly and timely issues later on in the project.
Pre-Drilling Site Surveys
ROVs can assist in pre drilling site surveys by confirming well surface drilling locations and identifying potential seafloor hazards (reefs, pinnacles, rock outcrops, etc.); man-made hazards (shipwrecks, well heads, communication & power cables, miscellaneous debris, etc.); and geological hazards (faults, erosion, buried channels, etc.). Using side scan sonar, magnetometers and bathymetry surveys along with video, ROVs are able to identify shallow drilling hazards and characterize the conditions of the sea floor.
