Valaris said it upgraded the vessel’s electrical system to secure the notation, which recognizes sophisticated system design to improve reliability and enhance protection. The electrical system is specifically designed to allow the drillship to optimize power plant performance, enabling operations on fewer generators and reducing emissions.
Gilles Luca, Valaris senior vice president and COO, said: “With this enhanced notation, VALARIS DS-12 exemplifies our company’s purpose of providing responsible solutions that deliver energy to the world. I want to recognize our engineers, our partner ABS and thank our customer bp, for their support. This is truly a remarkable team achievement that paves the way to more sustainable deepwater drilling.”
ABS has surveyed the upgraded system and tested it to ensure it can operate on reduced generator power. The short circuit and fault ride through capability was demonstrated on board the vessel with ABS in attendance, the drilling contractor said.
The EHS-E notation was introduced in the “ABS Guide for Dynamic Positioning Systems” in October 2021.
