Waterjet systems having sectional catcher tanks and related devices, systems and methods

A waterjet system, comprising:

• a fluid-pressurizing device;
• a cutting head operably connected to the fluid-pressurizing device, the cutting head including a waterjet outlet, the cutting head being configured to direct a waterjet toward a workpiece via the waterjet outlet;
• and
• a catcher tank having an internal volume configured to hold a pool of fluid such that the fluid is positioned relative to the workpiece so as to dissipate kinetic energy of the waterjet after the waterjet passes through the workpiece, the catcher tank including—
• a first tank section having a pair of opposing first wall sections, a first floor section extending between the first wall sections, and a first flange extending away from the first floor section,
• a second tank section having a pair of opposing second wall sections, a second floor section extending between the second wall sections, and a second flange extending away from the second floor section,
• a sealing member, and
• a compartmentalizing wall configured to be detachably coupled to the first and second tank sections between the first and second coupling surfaces, the compartmentalizing wall being configured to separate the internal volume such that fluid levels within portions of the internal volume at opposite sides of the compartmentalizing wall are independently controllable,
• wherein—
• the first tank section includes a U-shaped first coupling surface extending along the first flange,
• the second tank section includes a U-shaped second coupling surface extending along the second flange,
• the first and second tank sections are configured to be moved into operable alignment and detachably coupled to form a water-tight junction via the first and second coupling surfaces, respectively, with the sealing member operably positioned within the junction,
• the first and second coupling surfaces at least partially define a channel configured to receive the sealing member when the first and second tank sections are detachably coupled,
• the first and second flanges are configured to be bolted and/or clamped together when the first and second tank sections are detachably coupled,
• the first wall sections are configured to be spaced apart on either side of the internal volume by a distance from about 125 inches to 250 inches when the first and second tank sections are detachably coupled, and
• the second wall sections are configured to be spaced apart on either side of the internal volume by a distance from about 125 inches to 250 inches when the first and second tank sections are detachably coupled.

A method, comprising:

• transporting a first tank section and a second tank section toward an installation site in a decoupled state;
• detachably coupling the first and second tank sections at a water-tight junction to form a catcher tank after transporting the first and second tank sections, the junction including a sealing member operably positioned between a first coupling surface of the first tank section and a second coupling surface of the second tank section;
• and
• operably associating the catcher tank with a waterjet cutting head.
