Japan’s K Line is strengthening the equity of Norwegian unit K Line Offshore with a NOK 150m ($18.7m) injection.

The move brings the offshore vessel owner's total equity to NOK 1.27bn and follows a recent NOK 430m equity boost.

K Line, one of Japan’s biggest shipowning groups, is seeking to bolster the subsidiary amid a weak market for anchor handling tug supply vessels and platform supply vessels.
