NAPIER HARBOUR DREDGING

Extent of Whakarire's Overhaul WORK 0N BREAKWATER r In conneetion witfi dredging and the j extension of the Breakwter, the engin- « eer, Mr. G. W. B. Lawson reported to the Napier Harbour Board to-day as under: — Dredge Whakarire: The Whakarire i left Wellington after annual overhaul on the 10th inst., and arrived in Napier in the early houxs of Monday last, since when it has been engaged in preparing for the recommencement of dredging operations at the root and close Inshore to the west of wharf No. 4. On aeLount of shortage in the engiue-room Btaff, tho vessel is at present workiag only two ehifts tiaily. This year's overhaul was uot unduly severe, the major items (apart ficm the chipping and painting ot tha fiull and deckwork) comprising new deck sheathing plates, eonsiderable rerivetting of the bucket ladder, Tepairs and renewals to the chutes, and the general overhaul of machinery. Sundry other jobs such as the retimbering of hopper door landings, were also earried out. The overhaul costs are as yet hot ascextainable. Dredger Hapai: During the absence of the "Whakarire for annual overhaul in Wellington, the Auckland Harbour Board 's dredger Hapai was engaged in deepening the eastern side of the site for wharf No. 4 to its final depth of 35ft. "below low water and fqr its full greatest depth width of 100 feet. The material encountered in this eut was particularly easy and the dredger had no difficulty in putting up a really good performanee, which wasj uufortunately, to some extent off set by the intervening Easter holiday period. However, the Hapai 's returns amounted to 24,285 tons, bringing the dredger 's total output, since commencing work at Napier, tb 84,367 tous. "Breakwater Extension: The contractor for the extension of the breakwater built sections Nos. 9 and 10 thereof, thereby adding about auother 25 feet thereto and bringing the total length of the extension to 123 i'eet. He also made 86 larger-sized concrete blocks in the yard and deposited 39 core blocks ou the site of the works. "Excavation: Good progress was made with the excavation by motor lorries and crane and tub for the final location of the main railway lines between the Breakwater and the E shed. A eonsiderable quantity of rubble and concrete was met with in the' excavation, resort having on occasion to be had to blasting. The work was earried out for the most part by the Whakarire's crews while the dredger itself Was in Wellington for annual overhaul."
