The design and construction of the tank assembly workshops and the final form of the berth are described. The project, which was completed in 1991, includes a three-bay workshop building with leading dimensions of 136m length, 64m width, and 35m height to eaves. Other works include alterations to existing buildings, the strengthening of the roadway area between the workshop and the berth, and the development of the berth to include a skidding system and permanent launchways.

The strength and stability of trees The question of how an engineer might respond to a request to assess the prospective danger of a tree to a building with which he is concerned, raised in our issue for 19 November last, has called forth much comment. Sir Alfred Pugsley recalls his own interest in the fascinating topic of the structure of trees: Back in 1988 I contributed to The Structural Engineer (vol. 66, p322) a paper on ‘Limits to size set by trees’. I was mainly concerned with the elastic stability of the trunks as columns, and with an elastic limit to branch extension. But it shows that the limits are way beyond the practical extremes found in nature, which are governed by strength problems under wind forces. Verulam
Mr. M. B. Buxton, M.C., MA., A.M.Inst.C.E. (Member), proposing a vote of thanks to Mr. Frost for his paper, said that the Curnberland Hotel and its annexe constituted one of the largest buildings ever erected in this country, and by reason of the fact that it had bedrooms and living rooms situatcti all round the building, with no external lavatories and bathrooms -a system adopted in many of the Carlatlian and American hotels-it marked a great step forward. The paper and illustrations were of extraordinary interest, for they indicated the great difficulties duo to the site, in connection with the st.celwork and retaining walls, and the special construction adopted, and they indicated how those difficulties were overcome. The Institution was very proud indeed of the fact that one of its members had been appointed engineer for this great building. One might reasonably have expected that one of the well-known civil engineering firms would have been appointed. Mr. Frost was to be congratulated on his appointment, which had done honour to the Institution, as well as to himself.
