What this video covers

Damien and Pat modify the engine room of the steel-hulled tug *Salonica* to install a new day tank for the Cummins 855 engine.0:52 They repurpose an existing center tank, approximately 1,000 liters in capacity, by welding in new stainless steel fuel pickups, water drains, and sight glasses.1:53 Using a Unimig lift TIG welder, they install two pickups: one extending to the bottom for water drainage and a shorter one for fuel to prevent the engine from drawing water or air.4:18 Obstructions behind the bulkhead, including cement-filled bollard pipes, force a relocation of the fuel return line to the top of the tank.10:16 The project also involves converting two seawater ballast tanks into freshwater storage, requiring the crew to drain the tanks, pressure wash internal sediment, and repaint the piping to match international color codes.14:23 A gas leak in the welder briefly halts progress, requiring a teardown and inspection of the internal lines.12:48 Proper tank design for marine engines requires separate, height-staggered pickups to effectively isolate fuel from water and sediment.21:56
