documents regarding the transfer of the vessels that is going to be beached to the ship recycling yard authorities. The main particulars of the ship, special information on condition and seaworthiness of hull, and the method of towing/ sailing are to be provided in this document. This document is called as Physical Delivery Certificate. 5.6.2 Beaching Beaching is the process of transferring the weight of a floating vessel to the beach soil by sliding the vessel. Beaching is done when maximum water depth is available, at the site ie., during the high tide condition. Fig 5.4 gives photograph of a vessel beached in a ship recycling yard. Obsolete vessels having self propulsion capacity are beached by surging directly into the beach. Beaching of the vessels, without onboard propulsion unit is done with the help of tugs and shore pulling mechanisms. Bottom plates of the vessels come in direct contact with the beach soil during this operation. The condition of bottom hull plate of the ship is important as far as pollution prevention during beaching is concerned. There is a possibility of structurally week plates getting damaged causing spilling of fuel or cargo oil from the inside hull tanks. This operation involves certain amount of risk for non flat bottom ships like warships, patrol vessels etc.,. Possibility of capsizing of ships due grounding effect of ships can not be ruled out. This situation calls for analysis of stability of ships during the beaching operation. The entire operation which depends on high tide and tidal condition is very time consuming. The heavy and massive structure is moved and the movement is to be slow so as to prevent any bottom damage. Ship dismantling operations start after the ship is beached safely and evenly supported by the mooring mechanisms. Fig. 5.4 Beaching of Obsolete Ships (GMB) 60
5.6.3 Mooring /Sliding /Securing Due to insufficient tidal difference available in some recycling locations only small portion of the obsolete vessel will be available for dismantling operation immediately after beaching. Other portions will be still under the shallow water part of the beach. The vessel has to be secured well so that even during high tide condition, it will not be floating freely causing movement of the structure causing discomfort to the onboard dismantling workers. The vessel which is usually a massive structure, has to be moored and secured properly for safe dismantling operation. During available high tide water level, the partially dismantled structure has to be slide up facilitating further dismantling of parts of ships that have emerged out of water. Fig. 5.5 shows a photograph of the sliding process in ship dismantling. Improper mooring of the vessel results in unwanted movements which will hamper onboard dismantling operations. This will affect the safety of personnel engaged in marking, cutting and lifting operations. 5.6.4 Gas Freeing Gas freeing is the method used for removal of oil and inflammable vapour of oils so that the dismantling of ship’s parts using ‘hot works’ can be undertaken without any fire hazard. Inflammable materials remaining in tanks or piping such as fuel, lubricating oils, hydraulic fluids, cargoes and their residues and grease are removed and the vessel is cleared off gas and oil residues. Gas freeing is mandatory operation prior to the ship dismantling operation. Without proper gas freeing, the ‘hot work’ clearance certificate will not be issued. Fig. 5.5 Sliding of Beached Vessel (GMB) Drummed, tanked, or canned liquids or gaseous materials should be removed from the ship before the cutting of plates and stiffeners have commenced.
