A second wind farm service operation vessel (SOV) to be built for Louis Dreyfus Armateurs (LDA) at Cemre Shipyard in Turkey is to have an ABB Onboard DC GridTM at the core of a system which will also include tunnel thrusters, generators, transformers, batteries, the ABB AbilityTM Marine Advisory System – Octopus, and the company’s Remote Diagnostics Service.
ABB will provide its Power and Energy Management System (PEMS) enabling batteries to back up generators, thereby avoiding running spare capacity and saving fuel and maintenance over the longer term.
"This second order from LDA feels like a validation of the performance, cost efficiency and safety that ABB delivers through its 'Electric. Digital Connected' approach," commented Juha Koskela, managing director of ABB Marine & Ports.
The ABB set-up enables variable speed technology to optimise system energy use dynamically to correspond with load requirements, resulting in fuel savings of up to 20%. Power from the dual batteries will be introduced to maximise efficiency, and the energy stored can come from various sources, including renewables. Sensors transmitting data will enable the SOV’s performance to be monitored from shore.
The 83m-long vessel, designed by Salt Ship Design, will be deployed on Hornsea Project Two off the UK coast. The wind farm is due to come on stream in 2022 and will be the world’s largest wind facility capable of powering more than 1.3 million homes.
