US insurance broker Gallagher has acquired Oslo-based marine and energy broker Parisco as it seeks to increase its client base in Northern Europe.

Following the takeover, Parisco chief executive Dag Magne Torjussen and his team of 10 will join with Gallagher’s Oslo-based marine and energy insurance outfit Bergvall Marine, which is headed by managing director Anders Mjaaland.

Vyvienne Wade, Gallagher's chairwoman for Europe, the Middle East and Asia, said the move would help develop its ambitious global expansion plans.
