Rudder repair for the M/V %u201cEsvagt Beta%u201dCold straightening of rudder stock, including NDT before and after.PMI test of rudder horn casting material to support the welding procedure.Cavitated areas were grinded and welded up.Supply of bronze material for new bushingRealign the centerline of the rudder horn by machining to oversize dimension. Case/Damage:The vessel sustained rudder damage, resulting in a bent rudder stock and misalignment of the rudder-horn pintle centerline. Bent rudder stockThe rudder stock runout test showed a 0.5 mm deflection on the rudder stock cone, and we restored the alignment to 0.05 mm using our cold straightening method. The rudder stock sustained no other damage, and one day in our workshop, it was returned to the shipyard.Rudder repair in-situAs the rudder horn pintle bearing seat was out of line, there were two repair options: Welding up inside the rudderhorn casting or machine the rudder horn pintle bearing to oversize dimension and install a new bushing.Positive Material Identification (PMI)To identify and verify whether the rudder horn casting was weldable material, MarineShaft conducted a PMI test. The test result was used as documentation in the repair plan presented to the classification society, in this case, BV. Moving Rudder Horn Pintle centerline As the rudder horn pintle bearing seatwas misaligned, the repair solution was to machine it to an oversized dimension, realign the rudder horn's centerline, and install a new oversized pintle bearing bush.The shipyard had machine capacity forthe new bushing, and we supplied themwith the bronze bushing material, whichwe had in stock for immediate delivery.The shipyard also handled the reassembly of the rudder equipment. A case in point of successful cooperation between all parties in findingAdvertorialMarineShaft recently completed a repair of the rudder equipment for the crew change vessel M/V %u201cEsvagt Beta%u201din cooperation with the involved shipyard, Kynde & Toft.302 NX
