ESVAGT and Ulstein have entered into a contract for the conversion of two Platform Supply Vessels (PSV) into battery-powered Hybrid Emergency Rescue Vessels (ERRV).
The two design PSV PX121 Hermit Fighter and Hermit Prosper, designed by Ulstein Design & Solutions AS, originally built at Ulstein Verft and delivered in 2012, will return to the Norwegian shipyard for a six week stay to be converted into ERRV and in battery. Engineering work at Ulstein has started and the ships will arrive at the shipyard in October 2021.
The green transformation to hybrid propulsion will be led by Ulstein Power & Control. The final installation and commissioning of the hybrid system will take place in spring 2022 and in accordance with the vessel operating schedule.
“These improvements will reduce fuel consumption and emissions and extend the life of diesel engines,” said Rolf Ottar Rovde, sales manager at Ulstein Power & Control. “Ulstein Power & Control provided the power and automation solutions to ships as new builds. Our delivery now includes the power supply and automation system for the battery set, frequency converter, drives and panel rebuilding as well as installation and commissioning.
Ulstein’s full scope of work includes project management, procurement, engineering, power generation and deliveries and control. A battery deckhouse with network support unit for hybrid power will be prepared, methanol tanks will be rebuilt to carry liquids according to the OSV chemical code, and on the main deck new prefabricated deckhouses will be installed to accommodate areas of rescue and a new type ESVAGT fast rescue boats.
