Subsea equipment design and manufacturer Soil Machine Dynamics Ltd (SMD) has signed a contract to supply its Atom Mk1 1000m 100hp Work Class Remotely Operated Vehicle (ROV) system to Chinese power specialist China Southern Power Extra High Voltage Power Transmission Company (EHV, CSG), a subsidiary of the state-owned China Southern Power Grid (CSG).
The ROV will be used for inspection of the 31km physical power cable connections in the Qiongzhou Strait between Hainan Island and mainland China. The Qiongzhou strait often experiences high currents so it was essential that CSG chose a compact and powerful ROV to cope with the harsh conditions.
The Atom system is SMD’s lightest work class ROV suitable for offshore power applications, survey and light construction duties, and can be mobilized on vessels with limited deck space. For this contract, SMD will integrate a TSS350 cable tracking system and other survey tools to perform cable inspection.
Mark Collins, SMD business development director, said, “Our Atom system has a proven track record working in challenging operational environments, varying from shallow waters and high currents to scorching temperatures, all of which can cause significant problems for standard work class ROVs. For this order, Atom will showcase its ability to operate in high currents and will call upon its market-leading dynamic positioning system to ensure survey data is of the highest quality.”
Scheduled for delivery at the end of 2018, the ROV will be equipped with SMD’s range of Curvetech components, DVECSII control system and 20ft control cabin which will be mobilized on board CSG’s new cable installation vessel. As part of the contract, SMD Services is also providing bespoke training courses to ensure CSG’s operational team are prepared with the necessary operating skills.
SMD Services will utilize CRRC SMD Shanghai’s facilities to support mobilization of the ROV on board CSG’s new vessel. They will also lead on the sea trials ensuring the ROV operates at maximum capacity with support from the SMD Services offshore team, who will be on hand to provide assistance for any on deck ROV support.
