self anchored flatbottom tanks nomenclature

design problems of anchoring of aboveground steel tanks

The loads which impact on them are self-weight,snow,wind,earthquake,overpressure and vacuum.When the earthquake,overpressure and wind loads have high values,it is possible that the tank overturn or going to slide.To eliminate the threat from free moving,the steel facilities are often anchoredVessel Nomenclature from SeaSourcesB.Return to top.BACK BAR Used for the same purpose but on the opposite side to a bosom bar.BACK BOARD A portable back support nicely designed and fitted on the after side of the stern thwart in a small motor or row boat.BACK STAY Stays which extend from all mast levels,except the lower,to the ship's side at some distance abaft the mast..They serve as additional supports to prevent User rating 5/5Reference Guide for Deck Barges and Other ConstructionA barge is a non self-propelled flat bottom vessel used for transportation on oceans,rivers,and canals.While barges were once made of wood,todays barges are all constructed of welded steel.While barges vary greatly in size and type,they typically range from 90 400 long and 30 100 wide.
