Fugro Subsea Services has introduced 3D sea current profiles to its DeepWorks line of subsea simulators, allowing users to model complex currents at various depths and locations. The modeled currents provide more realistic environmental conditions for training ROV pilots and help dive teams better understand safety constraints for payout and management of divers’ umbilical cables to avoid hazards, Fugro says.
The same holds true for ROV tethers, the company says: configured current profiles simulate the physical effects of currents as the ROV tether moves through different current fields, around objects, and through deep or shallow waters. In cable lay operations, for example, the technology enables operators to determine how far the vessel heading must be offset from the trench to compensate for the effect of the current. ‘In deeper water fields, complex current profiles make it difficult, unaided, to predict cable touch down accurately,’ according to Fugro. ‘DeepWorks now enables different current settings to be tried in various scenarios, to determine the safe operating envelope and helps to validate procedures for optimal payout speed and vessel navigation.’
Users can define the strength, heading and elevation of currents and modify values during the course of a simulated mission. The 3D sea current modeling capability is available on new DeepWorks orders and as an upgrade to existing installations. OE
