What this video covers

Fabrication of custom stabilizer arms for the fishing trawler *Brupeg* continues with the alignment and welding of top plate assemblies. The crew uses a mag drill to prepare the top arm alignment pins and TIG welds stainless steel guide pins to mild steel plates.0:37 To maintain alignment during the process, the team tacks the stainless components to the mild steel before final welding.4:49 When a plate assembly pulls out of square, the crew uses a 12-ton jack to force the metal back into position for final welding and grinding.8:15

Simultaneously, the crew replaces the vessel's failed 24V AGM house bank with modular 24V 100Ah lithium batteries.9:43 Each unit consists of eight 3.2V cells housed in a stainless steel box, featuring a battery management system and accessible terminals capable of 200-amp bursts.9:49 The modular design allows for individual cell replacement at sea, providing a repairable alternative to sealed lithium units.11:41 The crew plans to install four of these batteries under the wheelhouse floor to match their previous 400Ah usable capacity.11:05
