Our Arctic is Opening UpThe Arctic is facing major
challenges as the ice melts
More shipping and oil and gas exploration are happening
An oil spill in the arctic would be a huge disaster
Many plants and animals would be harmed

Oil ExplorationDuring a recent exploratory oil drilling mission the Black Gold Oil Company
(BGOC) successfully located an offshore, ice-covered oil reserve and started
extracting.
Then…
A magnitude 5.5 earthquake struck and part of the pumping equipment separated under
the ice.

BGOC has contracted your company to build an ROV
1) Perform a scouting mission to search for
pools of oil trapped under the ice
2) Take a sample from a pool of oil under the ice
3) Return the sample to an analyzing station
4) Transport a piece of surface equipment
5) Respond to the open water spill in the
polynya and remove oil from the surface

OperationYou will be by the pool – you are not to go in
the pool!Keep batteries away from waterDo not drop control box in water The ROV Operator holds the control box
while the Tether Manager controls the tether.The Operator will pass the control box to the
Tether Manager when his/her turn is up. The next person in line becomes the Tether
Manager.

Possible DemeritsTeam member bickers, argues, or acts with
disrespect.
Pool-side structural modification after challenges have begun.
Team pulls tether to move ROV.
Use of pool “seal” after challenges have begun.

accomplish the tasks
Bigger ≠ Better
Distribute weight evenly

challenge? Where in the water column does your
ROV need to operate (at the surface or down in the water?
What shapes/attachments/tools does your ROV need to accomplish the tasks?Collect and
retrieve objects floating at the
surface.
Collect a small ring and deposit
it on an arm.
‘Fly’ through large rings suspended
underwater.

Motor PlacementAttach motors with zip ties The propellers should not be able to hit a wall or
floorMotors must be underwater when the ROV is at
the surfaceUp/down motor is best placed as close to the
center of the ROV as possibleSide motors can be placed at front, middle or
back of ROV Test motors so you know which way they spin
before attaching them to the frame
![Page 21: THE ROV CHALLENGE. What is an ROV? ROV = Remotely Operated Vehicle Unoccupied, remote controlled submersible vehicle Used in deep and shallow underwater](https://reader038.vdocument.in/reader038/viewer/2022103005/56649e055503460f94af2099/html5/thumbnails/21.jpg)

Up/down motor is best placed as close to the center of the ROV as possible.
Side motors can be placed at front, middle or back of ROV.
Test motors so you know which way they spin before attaching them to the frame.

BuoyancyAttach floatation with zip tiesThe top of the ROV should float level just
at the surface Think of where your weight is
You want floatation over the weightBalance floatation so ROV doesn’t tilt
side to side or point up/downYou can attach ballast (additional weight)
if needed

Share or modify parts of your kit.Go in the pool.Get batteries or control box wet.
DO…Show good sportsmanship.Learn something.Have fun!
