Singapore's BW Group is building its stake in Oslo-listed wind turbine vessel company Cadeler as Andreas Sohmen-Pao takes over as chairman.

Cadeler said its biggest shareholder, Swire Pacific Offshore (SPO), is in talks over a sale of some of its shares to BW following Cadeler's $100m initial public offering in November.

Swire Group has 42% and BW Group 20% of Cadeler.
