When designing a structure, it is important to consider:
TD
AY
Semi-submersibleplatformoilrigs
are heavy enough to be partially
submersed in water, but buoyantenough to still float in water.
This
kind of platform is useful in water
de ths between 60m-3000m
Forces acting on the structure
Whatforces are acting on your structure
o Natural forces from the environment weather, storms, natural
disasters!
o "an-made forces weight of ob#ects that the structure must
support and the resultingforces due to movement from ob#ects or
propulsion.
Directionof the forces acting on your structure$
o %re their forces acting vertically and&or hori'ontally on
your structure(
Typeof forces acting on your structure
o )ompression forces* forces that are pushing on your
structure
o Tension forces* forces that are pulling on your structure
o +ending forces* forces that cause your structure to bend.

Materials used
t is important to consider the purpose of your structure and the
environment
your structure will be built in.
The advantages and disadvantages of the types of material you
use. s itlightweight or heavy( )ost effective or epensive( urable
or brittle( /ill it float
or sink( /ill it erode or not( tc.
Shape of structure
1ome shapes are stronger than others for building triangles are
stronger than
s2uares, etc.!
The base of the structure must be strong enough and big enough
to support the
height and weight of the structure.
ou must consider the overall shape of your structure that works
best for the
purpose of your structure and the environment it$s in.0

Competition Grading Scheme
Structure
Is the structure structurally sound?
Doesnt easily bend or sag
Does it use proper supporting beams Does it use shapes that
Does it have appropriate joint connections
Does it have a proper base
___ /35 points
Does it look professional
Does it have even placed beams/joints
Is it symmetrical and does it look clean
Does everything have a purpose
___ /15 points
uoyancy
!bility for structure to float on "ater# 10 points
Structure floats evenly "ithout one side dipping noticeably# 5
points
Structure can "ithstand a "ave# 5 points
Structure can float "ith pump attached to it# 5 points
Drilling
!bility to successfully lo"er drill/ tube into "ater using only
string provided# 5 points
!bility to puncture surface using only $drill%# 5 points
!bility for structure to pump out all oil "ith structure still
floating 5 points
Bonus points: 2 points for every large s&uare magnet that
the structure can hold before
tipping over or sinking
