Ship history

In 2015, the two platform supply vessels, Britoil Power and Britoil Energy of the PX121 design, were delivered to Britoil Offshore Services Pte Ltd., Singapore. The vessels were constructed at Britoil's yard, P.T. Britoil Offshore Indonesia, on the island of Batam.

To Ulstein, the contract comprised a comprehensive equipment package including basic design, engineering support and main equipment supplied by ULSTEIN (generator sets, DP system, main azimuth propellers, tunnel thruster and retractable thruster, FiFi system, cargo handling system, etc.). Additionally, it included a large power and control package (electric propulsion system, integrated bridge solution, consoles, radio/navigation equipment, ULSTEIN IAS® (integrated automation system) and ULSTEIN COM® (internal communication system).

Britoil has long experience in ship services and transport. The two X-BOW® vessels marked Britoil's entry into the PSV market, as their fleet up to these deliveries mainly included anchor-handling tugs and barges.

The ships were built according to IMO's SPS Code (special purpose ships) and have OILREC class notation (oil spill recovery in emergencies).

Britoil Power was delivered on 13 August 2015, and Britoil Energy on 22 September 2015.


April 2018: Britoil Energy changed name to Topaz Energy.

February 2023: Fugro has decided to acquire the two sister vessels, Topaz Endurance and Topaz Energy (now: Fugro Resilience), and repurpose them into geotechnical vessels. Ulstein Design & Solutions AS has been contracted to redesign the vessels.

September 2023: Ulstein Verft has been contracted to perform the conversion of the Fugro Resilience. The major conversion work will be implementing a moonpool and building the foundation for a geotechnical drill tower and an A-frame.
