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 have been constructed at Britoil’s own yard, P.T. Britoil Offshore Indonesia, on the island 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 vessels are customised according to Britoil’s requirements. This includes one extra accommodation deck, allowing for a total complement of 50 persons.

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

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, and repurpose them into geotechnical vessels. According to a press release, the purchase supports Fugro's net 2035 roadmap, as these vessels are significantly more energy efficient than Fugro's current fleet and offer options for hybrid conversions and/or alternative marine fuels.
