Anchor repair

Posted in Marine Engineering, Ship Repair at 09:55 by Stranded Mariner

One of the main activities of the company I work for is marine repairs. Some of these works are being executed on board, but we also have a workshop ashore. Here we do standard repairs, like reconditioning of connecting rods, valves, pistons, cylinder heads, fuel injection equipment etc.

Every now and then though, we do some special repairs. Like the two anchors we received in our workshop yesterday. The bore of the hole, through which the anchor is connected with a shackle to the anchor chain, had worn out over time.

To repair this, we first machine the hole to an oversize, in order to allow a bush with the correct nominal diameter to be shrunk in. The bush is machined separately.

After heating the upper part with a propane or butane flame, the bush can slide in and is being held solidly in place after cooling down.

Both the oversize hole and the bush insert, have a bevel machined to it. To finish the repair, the groove between bush and body of the anchor top is filled up by a circular weld.
