NCS Survey, of Aberdeen, has been awarded a major survey contract by Saipem S.p.A. for pipelay support during the inshore phase of the Nord Stream Pipeline Project, two gas pipelines linking Russia with the European Union via the Baltic Sea.
The contract is valued at €2m to €3m and will commence in the middle of the year.
Andy Gray, NCS Survey Chief Executive, stated "We are delighted that Saipem has embraced this innovative technology, which gives them a high accuracy solution at an economic price. NCS Survey was selected due to our experienced project management team coupled to our innovative real-time sonar Touchdown Monitoring (TDM) system. The TDM system has gained rapid acceptance in the industry as it eliminates the need for a DP2 class ROV Support Vessel on pipe and cable lay projects in water depths less than 50m. The sonar actively tracks the pipe catenary during lay operations using the unique beam steering capability embedded in our TDM software. It enables the contractor to know exactly where the pipe is laid in real-time and thereby minimises the risk when laying near any subsea structures or other live pipelines even when there is zero visibility."
"In deeper water, TDM transducers can be mounted on an ROV giving it the capability of monitoring touchdown in poor visibility or from 50m away, which keeps it out of the high risk area."
