Oil storage tank foundation can be considered as ring wall if the storage tank doesn’t lay on the weak soil. The ring wall foundation dimension (thickness) can be calculated base on below consideration:
1. The I.E. Boberg Equation
T = 24 W / (q.H-80h)
where:
W = weight of shell supported on the ring wall (lb/ft)
H = height of tank […]

1. CREATE STRUCTURE MODEL FOR LIFTING
a) Determine padeye location (4 padeye for commonly use): this padeye’s location usually determining by suitable location on field.
b) Determine rigging point location (for dragging structure during lifting), usually use 1 – 2 point of rigging. Because of this rigging […]

STAAD is one of the structures analyze program which quite well known in the world. STAAD using the most modern technology in the finite element engineering, with data input method based on object oriented. STAAD program developing by professional team which has more than 20 years experienced research in Canada, USA and Europe.

One of the […]

We should probably know that Eiffel Tower, Empire State Building, Sears Tower, etc as one of high rise building on earth. That building was built on upland or onshore, but actually there also tall building that built on the sea floor.

The offshore oil platform building structures is begin with Forties (128 m), then Magnus in […]

The under construction Burj Dubai in Dubai, United Arab Emirates is the world’s current tallest freestanding structure on land, rising 604.9 m (1,985 ft). When completed, it is planned to rise over 800 m (2,625 ft). This building estimated completion will be around December 2008. Current skyscrapers (five tallest buildings in the world) […]

The example belowd is a simple tutorial to learn SACS. Cantilever with properties W24×104, the structure model can be seen below. Perform a UC member detail and moment diagram using SACS program!

SACS (Structural Analysis Computer System) is a program to analyze and calculating offshore structure (fixed platform). This program can perform inplace, seismic, fatigue, push over, TOW, jacket launch, flotation etc. Different from the other structural program, SACS can input many environment condition especially ocean force (current, wave, wind).

We can modeled fixed platform (offshore building for […]
