Unique Group adds long range profiling instrument Signature55 to its lease pool

Follow us

Leading integrated subsea and offshore solution provider Unique Group has added Nortek’s long range profiling instrument Signature55 to its global lease pool. The instrument has been acquired to give oil and gas customers flexible access to long range profiling capability. Unique Group chose the Signature55 because of its ability to provide ocean current profiling over a range of 1000 m. Another decisive factor was that the Signature55 works well for high-quality current measurements with fine vertical resolution (5 m cells). This makes the Signature55 well suited to customers working in 100-500 m depth, as well as 500-1000 m depth.

Equipped for real-time operational current measurement


The Signature55 will be delivered equipped for real-time operational current measurement projects, complete with a rugged 50 m cable, a topside interface box and MIDAS real-time display software. The same Signature55 may also be used with internal batteries for long autonomous deployments.

Enabling greater range and resolution


The instrument is available through GSE Rentals, a company wholly owned by Unique Group. “Our fleet is renowned for class-leading equipment, which gives our clients the most efficient, reliable and economic means of acquiring accurate data during a survey”, says Alan Cameron, General Manager at GSE Rentals. Mr. Cameron emphasizes that the Signature55 is a reasonably compact profiler that utilises the latest technology, which enables greater range and resolution. “Our past procurements of Nortek instruments have repeatedly proven to be exceptionally reliable and popular with our clients. The addition of a Signature55 to the fleet assists us to meet our clients’ requirements for deep water ADCP’s, both moored and vessel mounted.” The Signature55 will first be leased and used by Tideway BV – a company specialising in landfall construction, scour protection and pre- and post dredging for the support of pipe laying operations.
