Equipment & Technology - June 28, 2012

Nautronix has been awarded orders to supply upgrades to NASDrill USBL Transponder digital acoustic positioning systems for two of Songa Drilling’s semi-submersible drilling rigs, Songa Venus and Songa Mercur, both currently operating in Malaysia.

The systems are due for delivery in June and August 2012 respectively.

Both these rigs have been operating with Nautronix analogue RS912 USBL systems since the early nineties but have seen the substantial performance and acoustic reliability improvements that Nautronix ADS2 Digital Acoustics will deliver from the NASDrill USBL system in operation on their Songa Dee drilling rig.

Mark Patterson, Nautronix CEO, commented: "We are delighted to secure these upgrade orders and is further recognition the industry recognises the benefits our established digital ADS2 products offer."

NASDrill USBL systems have been designed specifically to meet the requirements for a reliable, stable and accurate position reference and riser angle monitoring system for demanding offshore operations for both moored and DP drilling rigs and can operate  in both transponder and pinger modes dependant on customer requirements.

The NASDrill USBL system provides a reliable and robust system to meet positioning needs up to a 4500 metre range with accuracy of 0.5m or 0.5% slant range including any motion errors based on interfacing to 0.1° dynamic accuracy VRU.

This performance is achieved using a 225mm diameter interrogate/receive surface transponder avoiding the need for the large gate valves and expensive surface transducers used by some other suppliers
