Andreas Sohmen-Pao’s BW Offshore is continuing its transition from floating production, storage and offloading vessels with another sale.

The Oslo-listed owner said it has completed the disposal of the 28,000-bpd BW Athena (built 1994) to a third party.

No price was given for the 125-metre Bermuda-flagged vessel.

“The transaction is part of BW Offshore’s strategy to transition to floating energy infrastructure investments,” the company said.

BW Offshore will book a small profit from the deal. The FPSO was debt-free.

The former BW Carmen tanker was acquired for $80m in 2003 from Thome Ship Management.

It was converted in 2012 and worked on Ithaca Energy’s Athena field in the UK North Sea until 2016.

The BW Athena has since been laid up in Scotland.

In March, the owner sold the 35,000-bpd BW Opportunity (built 1989) to an unnamed buyer for $125m.

And last June, the 7,000-bpd BW Joko Tole (built 1988) went to Indonesian owners Bahari Inti Tanker, Cahaya Haluan Pasifik and Buana Lintas Lautan.

The group will be left with eight FPSOs.

BW Offshore said last month it was exploring an “industrial-scale” concept for a floating vessel to produce green ammonia.

This project has secured approval in principle from the Norwegian classification society DNV.

BW Offshore can now begin the basic design phase.

The “NH3 FPSO” concept is being developed in tandem with Netherlands-based energy company SwitchH2.

The idea is to convert an existing VLCC or build a new ship.
