Key Features

Choice of fixed or portable command units

Full integration with rig's exisiting Sonardyne acoustic positioning systems

Portable system allows system to be operated at distance away from rig

Deep rated dunking transducer allows ROV to operate the system close to wellhead

Incorporates Sonardyne's highly reliable Wideband signal technology

Sonardyne’s BOP surface control system is supplied in both fixed and portable versions.

The fixed control system is installed permanently on the drilling rig and operates via a hull-mounted acoustic transceiver. If the rig is already fitted with a Sonardyne acoustic positioning system, for example a Marksman LUSBL system, then the acoustic BOP Control System can utilise one or more of its existing hull-mounted transceivers, otherwise a dedicated hull-mounted transceiver is supplied. This is normally installed on a deployment pole, typically 10 – 15 feet below the vessel hull and clear of the main noise source, the thrusters.

The fixed control unit is a 19” rack-mounting panel containing large push-buttons to initiate an emergency disconnect sequence and a multi-line LCD display providing operating instructions and status information.

The portable command system is a self-contained unit that can be used as an alternative to the permanently installed surface unit. It can be operated from a small vessel, a life raft or a helicopter, using the dunking transceiver and cable supplied. The dunking transceiver is depth rated to 4000 metres so that it can be fitted to an ROV and during a subsea blow-out can be moved close to the wellhead, to communicate over a shorter range and away from any oil and gas plume. This gives a much higher signal to noise ratio and much greater likelihood of successful communication.
