TSS 440
The TSS 440 is a well-established survey instrument, widely used in industry for detection and tracking of subsea cables and pipelines either on or beneath the seabed.
The TSS 440 has been interfaced with the UTROV® to allow additional tooling, such as grabs or dredge pumps to be mounted simultaneously. As a consequence, the TSS 440 can be mounted during project mobilisation and remain on the UTROV® for the duration of the project, resulting in less time spent performing tool changes.
The TSS 440 interface features hydraulic positional control, where it can either be in a compact, stowed position for launch and recovery through the splash zone, or it can be lowered into its operational position, extended far enough away from the UTROV® frame as to prevent a drop in resolution (background noise).
As of February 2021, Utility ROV Services has conducted over 108 hours of TSS 440 operations across two separate projects, with a high degree of success. The UTROV® has a proven track record of conducting TSS 440 operations in regions where currents regularly exceeded 2.5 knots — conditions above the operational limit of a typical WROV.
