What this video covers
The owners of the former fishing trawler *Brewpeg* are extending the vessel's main and generator exhaust stacks to prevent exhaust fumes from entering the wheelhouse and solar array.12:08 Because the boat lacks the high A-frame structures used by commercial trawlers for bracing, the crew must balance stack height against the need for structural stability.17:33 They fabricate a 1.37-meter extension for the six-inch stainless steel main exhaust using a jig made from angle iron to ensure alignment during welding.22:31 To manage engine room ventilation and fire safety, they design a stainless steel shroud that acts as an air-cooled chimney, incorporating a closable vent flap for CO2 fire suppression.12:37 The project also includes installing rubber-mounted six-inch exhaust clamps to prevent stress fractures.34:04 Work is currently restricted to a temporary work berth, as the vessel’s upcoming move is delayed by a nearby cyclone.33:20 The crew prioritizes exterior welding and fabrication tasks while in the berth, as these are not permitted at their next location.12:15
