V1S Saves Season for Fishing Vessel

The Problem

When a seal fails on your net hauler hydraulics out at sea, the costs and lost profits stack up quickly. In this instance, salt water began entering the hydraulic fluid on a 245 ft (75 m) purse seiner through a seal leak, rendering the net hauler out of commission. Faced with frequent fluid exchanges at a cost of $9300 plus disposal, or worse, substantially larger lost profits from downtime for replacement of the seal, the vessel owner was in desperate need for a solution to allow him to continue operating without fear of malfunctioning equipment.

Through fluid analysis it was found that the 265 gal. (1000L) reservoir of ISO VGA 32 hydraulic fluid contained 28564 ppm of water. If the ppm could not be reduced below 200 ppm it would inevitably have to be replaced.

The Solution

A goal of reducing the water content to < 150 ppm was set and a V1S portable vacuum dehydrator was installed on the reservoir. The V1S ran for 10 days with samples for analysis being drawn on days 1, 3, 8 and 10.
