Pontoon Floating Roof Design

12 in single deck roof which shown in figure 1 6 is also called pontoon roof the buoyancy is derived in the pontoon an annular circular pontoon radially divided into liquid tight compartments.

Pontoon floating roof design.

Our innovative design eliminates the likelihood of pontoon end cracking a common phenomenon in light weight ifrs that results from tank turbulence or landing the floating roof during cycling. In 1952 when ambrose weeres invented the first pontoon motorboat little did he know that he was doing the world a lot of good. To study roof pontoons design a buoyancy analysis of the floating roof was established with punctured pontoons. The allentech hybrid stainless steel aluminum internal floating roof was developed for products which may be corrosive to aluminum in the liquid phase.

The obeyed methodology of this study is by calculating the center of gravity and moment of inertia of the floating roof in each case. The floating roof must be provided with landing legs that are designed to support the external floating roof under a uniform design load of at least 25 psf api 650 appendix c 3 10. Pontoon type floating roofs are the most economical type of floating roofs in the market. We ve done so by ensuring our ifr has a proper frame with regularly spaced crossbeams.

One is the foam filled u shaped pontoon another is the round baffled single chambered pontoon and then there is the single round pontoon with several airtight individual compartments. Pontoon boats 101. The length of the legs must be adjustable from the top of the roof and the legs must be notched or perforated at the bottom to provide drainage. There are three primary types of pontoon designs used on current pontoon boats.

The deck sits on top of the pontoons which allow it to float clear of the product surface. In this study three cases were applied to analyze the buoyancy of the floating roof in each case. This hybrid skin pontoon type ifr is the same basic design as our aluminum skin pontoon ifr except that all submerged or partially submerged components are constructed of stainless steel.

Ergil storagetech internal floating roofs which minimize the evaporation losses of stored products such as jet fuels gasoline diesel and crude oil can be supplied as aluminium or stainless steel. Due to environmental issue selection of the roof seal is one of the major concerns in the floating roof tank design. It is a boat with a large flat deck that s mounted on two or more metal tubes called pontoons floats.
