The depth of the water, proximity to the tank farm and vessel unloading facility, 10'-to-12' tides, 28 degree water temperatures, periodic wake from passing vessels, winter storms and constant icing were all challenges for working on the barge.

Outcome

Drilling and blasting proceeded successfully.

Schedule

Six days a week, 12 hours a day, January through April.

Summary

Working with other experienced marine contractors and a sophisticated customer. Maximizes the results from teamwork.
