Steve G. - BP ECOW Support / OM&S Training Coordinator BP Husky Toledo 

Bob Grace and his company (Great Lakes Underwater Services) have performed diving operations (inspections, repairs, surveys, soundings and 3D underwater Sonar Imagery) for BP Husky Toledo Refining at our marine dock for many years. The work has always been performed as planned and was executed safely and on time. Great Lakes Underwater Services will always be the first company I would call for any dive-related operations.   Bob and his son Tony are top tier people, both professionally and personally. Their professionalism  and desire to provide safe, efficient, and complete underwater inspection and service much beyond the client’s expectations are cornerstones of the company they represent and are why I recommend them in the highest degree.                                                                                                              Kindest regards, Steve G.
