T&R Bulletin 3-11 is a 133 page soft cover book.
In January 1958, Panel M-15 (Heat Balance) of the Society of Naval Architects and Marine Engineers Technical and Research (T&R) program was formed to investigate the possibility of standardizing the assumptions and allowances and methods of treatment of heat balance calculations. The result of the Panel's work was published in November 1961 as Technical and Research Bulletin No. 3-11, "Recommended Practices for Preparing Marine Steam Power Plant Heat Balances" and found universal acceptance in service; However, the need for additional practices relating to sea trial was soon evident and the Panel in January 1968 prepared T&R Bulletin No. 3-17, "Recommended Practices for Correcting Steam Power Plant Trial Performances." Changing practices and increasing capability of marine steam power plants necessitated the revision of Bulletin No. 3-11 which was prepared under contract from the Society in 1971 under Panel's guidance.
