Repairing Aviation Fuel Tank: Approaches and Timeline

Okay Kim,
I understand the urgency of the situation, having to receive 4 million liters of Aviation fuel within
three weeks potential massive losses in revenue, as well as potential financial losses of up to $ 3
million monthly if you are not able to deliver the fuel to the customer. Although we are already
behind schedule in getting the tans repaired, we are able, based on our experience and technical
resources and knowhow to have the tank ready to receive the fuel in three weeks time. There are
two ways we can go about this, the first being to change the work schedule and task execution style
and the second method is to work faster and reassign staff and time resources to complete the repair
tasks faster and without any significant requirements for additional funding/ finances. Changing the
work schedule will involve getting tank 3 repaired and ready, although this will take slightly more
time than the other tanks because tank 3 is the largest. The reason we will start with tank 3 is
because it is the most easily accessible wand will not require cranes to get the work done:
accessibility issues with the other tanks will slow us down further. Starting with tank 3 will ensure
all the delivered fuel can be stored as it is the largest of the three tanks. We can have tank 3 ready by
overlapping tasks so that other tasks start while others are being undertaken. Repair on tank 3 will
be started on Friday 13th and the team will work partially on Saturday (half day), while regular work
days will see us working an additional two hours (over time). We will allocate more resources
(time and manpower) to the task of repairing tank 3 so that more is done in a shorter time period
based on a project management principle we call task compression which is achieved through fast
tracking activities and crashing through allocation of more resources without adding to the costs.
Putting the 6 steel patch in place will be complete by Tuesday 17th and the task of putting the four
steel anchor on top of the tank will be started on Monday the 16th when placing the 6 steel patch is
about to be complete. As such, the 4 steel anchor on top of the tank will be complete on Friday 20th;
the replacement for the water supply system to tank 3 will commence on Wednesday 18th and will
be done at the same time as the 4 steel patch on the tank top is being put in place and will be
completed on Saturday 21st. Cleaning will also be overlapped to start on Wednesday 18th and will be
completed by Saturday 21st. On the prior day of Friday 20th, we will commence the repainting
process and have it completed by Tuesday 24th of April. This approach will ensure the allocated
number of days are taken to complete the tasks in order to guarantee quality; however, the tasks will
be overlapped and done at the same time rather than starting a task at the end of another one. We
will work on Saturdays as well to ensure the tank is ready in three weeks. The other method is to
continue work on the tank 1, but still using the same approach of overlapping and completing tanks
concurrently because the dependencies on most of the tasks are not absolute as the project schedule
depicts. The reason they were planned to be done sequentially was because of the adopted waterfall
project execution style; we will change the style to have some elements of agile, where the time
