Offshore Windfarm & Subsea Cable
G8 WindPro® Overview
WindPro®, provides comprehensive expertise in the planning, design and construction of windfarm cable systems. It contributes to every aspect of windfarm engineering project; providing technical and commercial knowledge right from the beginning from site surveys, cable route survey, risk management, route clearance, subsea cable installations, burial protection, project engineering, project management, repair & maintenance services and vessel support.
WindPro® Cable Route Selection
This vital resource brings essential insights into cable routing around natural and manmade hazards, environmental requirements and regulatory processes. Our studies incorporate information gathered from academia and industry and has developed over 25 years of working with data from seabed bathymetry to ocean currents, through shipping, fishing and marine activities. Our investigative site visits for cable landings cover all aspects of physical, regulatory, environmental and commercial considerations.
WindPro® Cable Lay
Cable lay vessel is equipped for both shallow water and deep sea cable laying with 2 main tanks and 1 spare tank with total of 5000T cable capacity. The Kongsberg Simrad DP2 class vessel has a 360o pedestal 30T @ 8m knuckle boom crane and two 360o pedestal knuckle boom deck cranes of 2.5T @ 20m and 5T@11m. Fitted with A frame of SWL 60T. The helideck and fire -fighting is in accordance with CAP 437 and fully air-conditioned flag state certified accommodation for 84 pax.
WindPro® Multicat vessel is designed for multiple roles undertaking varied assignments in diverse working environments. The low draft vessel with G8’s equipment onboard provides support to subsea burial operation. The 2000 BHP, 30T bollard power is effective in shallow water and provides accommodation for 10 pax. The wheelhouse has also 360 degree visibility which ensures the highest standards of the safety on deck.
WindPro® Cable Burial and Protection
G8 CablePro® services provides technology & resources involved in cable laying along rivers and harbours and trenching of array cables in difficult conditions. This has firmly established our knowledge of marine surveying, sediments and cable engineering, to ensure risk mitigation. We create confidence to make the right commercial and technical decisions on cable burial technology to achieve a safe and effect cable installation.
G8 accelerates and advances the implementation of large scaled industrial solar with developers and utility partners. We are developing the industry's first 20MW rated floating modular substation Solar Arc with the application of ESS (Energy Storage System) and STM (Stable Tension Mooring) to improve the economics, stability and availability of Giga Watt and Mega Watt scaled solar energy system.
G8 Developing World's First 20MW rated Intelligent Floating Solar Substation

By: Mohan PANAYAMADAM
G8 Developing world first Intelligent Floating Substation for Floating Solar and Offshore Wind Industry. In the company's drive to accelerate large scale Floating Solar & Offshore Wind Power, G8 is launching the GW Solar Floating Substation system that will increase the reliability and efficiency on Industrial scale Floating Solar and Offshore Wind Energy Systems.
Each GW Floating Substation aka ''SolarArc'' is fitted with G8's Proprietary STM (Stable Tension Mooring) System and Intelligent Remote Monitoring SCADA network to provide industry leading efficiency and advance deployment of Giga Watt scaled offshore renewable energy system.
SCADA systems for Offshore Floating Solar PV (OFPV) Farm – An advanced energy management integrated system
G8’s Energy Division broadened the already flexible SCADA to a renewable OFPV-SCADA to control and operate an Offshore Floating Photo Voltaic plant (OFPV) through the digital transformation of streaming data received from the asset frame work to scalable and actionable information for improved safety, operational efficiency, infrastructure reliability and visualising the cost & profitability.
OFPV-SCADA is a Supervisory Control (SC) and Data Acquisition System (DAS) that supports the OFPV operator to control the plant locally or at remote locations. This integrated software and hardware control system with Energy Storage Control Ready (ESCR) module enables the operator to interact with system elements such as sensors, inverters, transformer, switch gears, substation through an user friendly Human-Machine Interface (HMI). As expected, the SCADA gives real time intervention, record of events, playback with historical data etc. and helps the FPV to maintain efficiency, process the data for smarter decisions, and to address system issues to mitigate downtime.
OFPV - SCADA - ARCHITECTURE
The system handles the environmental data, GPS positioning of the floating PV, mooring line tension details and compares with baseline through sophisticated mathematical models and algorithms in addition to the control & monitoring of the performance of PV panels, inverters, transformer, health of submarine export power & control cable and substation equipment.
The system runs advanced analytics on historical data, understands performance expectation and reports the real performance relative to expectations. By feeding weather data, the OFPV-SCADA can provide accurate energy forecasts, lost energy report including rate schedules to evaluate the OFPV farm’s financial performance.
The OFPV-SCADA is an essential tool for any OFPV clean energy operator as it gives effortless management in Operation, Administration and Maintenance (OAM), fault identification and rectification through early diagnosis to ensure optimised operation, improve the safety, errorless documentation and billing through highly intelligent and configurable analytical add-on modules.
