DECK THREADED HOLES OF THE AFT WORKING DECK SWL: 2,5 T Repair of the threaded holes, the thread of which (M 30) is damaged. At the beginning of the work, the location of the deck threaded holes concerned will be presented to the shipyard. A location plan will be given to the shipyard. Two actions are possible: 1.1 Complete replacement of the threaded hole - Removal of the threaded hole, cutting of underlying stiffeners. - Chamfering of the deck sheet metal. - Check of positioning between-centres of the threaded hole. It is imperative to be sure of the thread defined in the transversal and longitudinal directions. Unless there is another definition on the plan the following holes threads shall be observed : - Transversal thread: 800 mm. - Longitudinal thread: 1100 mm. - Upper welding in several passes. - Grinding of the welding in order to be flush on deck. - Rewarding of under-deck stiffeners (gussets, flats, carlings) and welding under the deck of the threaded hole. - Inspection of the wildings with dye penetration test..
