As price pressures continue in the ROV industry, the need for operators to reduce operational costs through the adoption of new technologies is increasingly apparent.
For areas such as seabed mapping and pipeline inspection, where traditional work class ROV systems remain the preferred choice, SMD has recognised the limitations of the current technology available and developed FLO, a new high-speed Survey and Inspection ROV system, capable of delivering higher quality survey data and significant time savings in offshore operations.
Traditionally, standard work class ROVs have speed limitations due to their size, weight and hydrodynamics. They can also be unsteady operating at higher speeds.
SMD engineered FLO, a high-speed variant based on proven SMD ROV fleet technology, to perform tasks faster and more efficiently. The new system has a top speed of 6 Knots and the ability to hold position in currents up to 4 Knots from any direction. FLO also boasts 50% faster survey times compared to conventional work class ROVs and is capable of significantly extending the operational window in areas where high currents are prevalent, especially within the renewables sector.
From concept to manufacture, the new high-speed ROV by SMD, has been designed around the latest sensor payloads it would be tasked to carry in order to perform offshore, whilst also providing the most stable and acoustically quiet platform possible to gather quality survey data.
In order to provide this level of performance, FLO uses SMD’s advanced ROV drivetrain technology in a low profile hydrodynamic package less than half the height and half the weight of a typical Work Class ROV. Coupled with eight open water vectored thrusters and SMD’s advanced ROV control automation, FLO is able to accurately navigate and remain stable at high speeds while close to the seabed.
FLO can also be operated in free swimming mode for shallow water and uses a tether management system (TMS) in deeper water. Although travelling at high speed creates drag on the ROV umbilical, in water depths of 500m in free swimming mode, FLO has the power to achieve speeds greater than 4 Knots.
To ensure optimised deployment and retrieval of FLO in difficult conditions. SMD has drawn upon its’ 45 years of Deck Equipment design to offer purpose designed LARS system which incorporates innovative functions including the auto cable render and a gimballing docking head.ROVS
