Hydrex In-situ repair of 40 ton azimuth thruster on crane barge in Gabon

When one of the four 40 ton swing-up azimuth thrusters of an offshore crane barge which was servicing rigs on an oil field off the coast of Gabon malfunctioned, Hydrex was called in to remove the thruster and perform the necessary repair work while the unit stayed at anchorage just outside the field.
