Owned by Chevron Corporation, this wharf
normally has several ships docked here at a time. Even on weekends,
the wharf is usually busy. Because of dangerous vapors that are emitted
from the oil products, the survey crew was not able to operate near any
of the docked ships. Fortunately, this weekend was a little slower
than normal and provided an opportunity for the surveyors to get their
work done.
|
| Measuring the outer edge of the wharf
provided some interesting challenges. Because of the extended length
of the wharf and the congestion of pipes, buildings, and other structures,
a direct line of sight to some of the outer edge positions from the reference
points was impossible. These points were measured by the GPS survey crew.

Another problem had to do with the actual
corners of the wharf. Many of the corners were badly chipped.
As experienced crew members, they knew how to improvise, by adding to their
survey equipment to a flat metal bar that allowed the tripod stand to rest
over corner points that were no longer there.
|
| In addition, the curb next to the edge,
provided the survey crew with difficult maneuvering of the survey tripod
as well. For results of the survey click here.
