1910 Acquired grounds previously occupied by William Beardmore and Co (and before that by Robert Napier and Sons) which considerably extended the Govan yard. The boiler shop was at Lancefield on the opposite side of the river and engine works were at Anderston Quay, both of which had been extended and improved in recent years.
1912 The directors had been considering for some time the advantages of disposing of the business and recently Harland and Wolff had made an offer to acquire the business; the business would continue as before in both Naval and mercantile contracts.
Harland and Wolff acquired the London and Glasgow Iron Shipbuilding Co's shipyard, together with the adjoining yard of Mackie and Thomson, and Robert Napier and Sons' old yard, which by this time had been vacated by William Beardmore and Co. All these names disappeared, and the three Govan establishments were laid out as one large modern shipyard. The engineering works of the Old London and Glasgow Co. were greatly extended, and adapted for the construction of Diesel engines.
