As the LPG tanker was just making for the Netherlands port of Terneuzen it suddenly experienced problems with its steering capabilities and needed some quick thinking and a fast solution. Thus, UMC was asked to attend the vessel and carry out rudder repairs as per class approved procedures.
The location of Flushing, on the Belgium/Holland border strategically located between the Scheldt River and the North Sea was the ideal spot during a cold January to carry out the repair.
Jean-Paul Engels, GM of UMC’s European network said, “As soon as the vessel came alongside its lay-by berth our divers were ready to carry out a pre-repair survey and noted that the flap of the Becker rudder was hanging in a 5 degrees angle due to the upper pintle being broken off. The flap was first re-located in its original position and UMC staff than started with making measurements for the final repair.
He continued, “We were able to bring in our experienced underwater repair staff and coded welders to first remove the entire flap link pin assembly and than weld six 1000x150x20mm stiffeners onto the rudder flap & rudder both port and stbd. sides in order to create ‘one solid rudder, without flap’ capability.”
The most challenging event was the strong tides and weather conditions that caused zero visibility at times, but despite the delays encountered due to underwater conditions, the repair was completed within the time frame available and thus, the vessel could meet up with Charter’s schedule as planned after attending Lloyds surveyor had approved repairs as carried out.
UMC’s marine engineering capabilities solve commercial, naval and offshore demands from super yachts and warships to cruise liners and jack-up rigs.
With Operational Hubs covering Europe to the Far East – UMC has the resources and technology to fully support the maritime industry.
