Metalock travelled to Copenhagen with 22 technicians and 4 tons of equipment

At the end of May 2002, the Metalock Engineering Group travelled to Copenhagen with 22 technicians and 4 tons of equipment and began with the repair work immediately after the ship arrived. Four old, cracked crank case plates were removed, the tension rod and foundation bolts in the repair zone were unfastened, and the bearing block was properly positioned in accordance with web deflection. The steel plates provided by the company Sulzer Innotec were then cut out using a laser and simultaneously welded in the engine room by 4 experts. The position of bearing block No. 8 was controlled and corrected, as needed, by constant web deflection measuring.

After the welding work was finished, bearing shell No. 8 was restored and bedded. Further assembly work, such as tightening of the tension rod and foundation bolts, cleaning of the oil outlet filter and removal of the dust cover, along with flushing of the crank case and performing of test runs and sea trials, concluded the repair work.

The work was completed, all to the satisfaction of the owner, classification society and insurance company, in 10 days, 3 days earlier than planned.
