Practice, practice, practice. How do you become an experienced senior diver? You guessed it. This is the “Repair and Demolition Issue” a very important facet of what we do in this industry. As a matter of fact, the skills used in repair and demolition projects are among our most basic, including rigging, burning and use of other underwater tools. Theoretically, all commercial divers have been trained in the techniques and tools utilized in repair and demolition, but like all skills everything takes practice and discipline in order to be good at it. All the inspection and reporting skills you have read about or have been taught are required, including use of UW video inspection, UW photography, rulers, incline measure- ments, depth indicators, NDT gear and fabrication skills. I do not want to forget to mention underwater burning and welding and hydraulic and pneumatic tools and skills. With each skill set comes terminology specific to a project. Make sure you are describing what you see with proper terminology before you enter the water. I have been on projects where the inexperienced diver refers to the bilge keel as the rail line on the side of the ship…Excuse me, where are you and what are you looking at? I remember once when a diver was asked to describe the condition of an underwater tunnel structural brick work. The diver paused and stated he saw bricks, “lots of @#$%$#@& bricks!” When prompted to describe the grout between the bricks, he responded with, “Yep, lots of grout.” Then the questions began. I will always remember the look of the supervisor and the client’s engineer just before we were instructed to bring the diver back to the surface. To be an exceptional diver requires dedication and the willingness to do your best at all times; this includes being safe and being informed. Yes, safety always plays a big part of one’s behavior on the dive-site; with safety comes familiarization on what you are tasked to do and how to best describe what you see in order to meet the requirements of the job. If you are diving on a dam, a ship, a pipeline, a platform or a pier, learn the proper terminology of what you are working on. Clear communication between the diver and the surface can make the project run a great deal smoother. In September, the industry lost another great member, I am sorry to report the passing of a friend and one of my mentors, Dr.
