Description

Requirement for Supplier to overhaul the following: -both the Port and Stbd Azimuth Thrusters -both the Fwd and Aft Tunnel Thrusters plus the four Planetary Gears are to be part exchanged or offer an alternative cost-effective solution The vessel should enter the dry dock as early as possible on Monday 31/01/2022. It should be planned for the Azimuth thruster service engineers to arrive this day to commence work on the thrusters on Tuesday 01/02/2022.
