When it’s blowing a 45kts Sou’wester with 10m swell running and the hauling room bilge pump stop pumping, its time to stop fishing and close the hauling doors to keep the water out while the chief fixes the problem.
There are several pumps through out the factory, the hook room, line deck and the hauling room. The hauling room is the only working space open to the sea for long periods of time, (hauling lines occupies about 70% of the
day) and is designed to be a wet area.
The hauling room pump is the biggest pump aboard, it can shift 4,100 liters a minute, and in bad weather with water pouring in every few minutes, we can’t operate without it. The vessels stability is not affected by having water in the hauling room.
These big pumps do not normally fail, for that reason we don’t carry a spare. We could use a smaller pump but that would limit the amount of weather we could work.
The chief will just have to repair that pump.
Greg tells me the cast iron impellor was shattered in two places around the boss or where it connects to the shaft. He was able to make a support ring and braze the shattered bits together around it, then fill the gaps with plastic steel, machine the impellor to fit the shaft and put it all back together with lock-tight. We have now removed the smaller standby pump and put the big feller in and we’re back in action.. thanks to some classic engineering skill from the Chief.
