An Arid Bilge Systems Series 9 nine zone system was installed on January 4, 2008 in the aft most Starboard watertight compartment. Quarter inch copper tubing was used throughout this installation to meet the MCA fire standards. The discharge is routed through the Arid Bilge Systems Eco Friendly Discharge Companion to the right of the main unit, where the bulk of the bilge oil, fuel etc. is captured.

View below the before picture under the floor of the Starboard guest cabin.

The same compartment dried but not cleaned with the Arid Bilge Pickup in the center of the picture. More than 60 feet of quarter inch copper tubing was pulled through four watertight bulkheads to reach this compartment.

Shown below is the view under the floor of the Starboard aft crew cabin before installation of the Arid Bilge System.

Shown below, the same compartment 48 hours later with the Arid Bilge Pickup added. After the compartment was dried by the Arid Bilge System, a rag was used to clean away the loose dirt.

Yes, a full two inches of residual bilge water used to remain under the brand new C-15 Caterpillar mains in this before picture. With MCA requirements of watertight compartments and watertight hatches comes reduced venting during vessel storage. With the sun beating down on the decks and side of the vessel, this engine room heats up during the day, causing accelerated evaporation of the bilge liquids. Climb down into this engine room to work at 11:00 AM in the morning and be greeted by nearly unbearable working conditions. The human body starts to sweat rapidly, but because the humidity already nearing 100%, little evaporation of sweat from your skin takes place, resulting in your body temp climbing and your clothes becoming drenched. What happens to the engine room machinery under these conditions? Will any human technician relax, think and take the time to fix anything correctly under these working conditions?

Below in the after picture taken two days later, notice that the dirt and dried water line remains. Looking at this picture, can you feel the difference in the air with the greatly reduced humidity levels?

This compartment was accessible, so it was cleaned and painted after the Arid Bilge System maintained it dry for two weeks.

Under the Starboard cockpit hatch is a compartment where MCA requirements prevented drilling a drain hole exiting to under the vessel, because this might allow the reverse flow of water under certain sea states. Once again you are looking at two inches of residual water which makes this a near worthless compartment for storage purposes. 

The versatile Arid Bilge Pickup Wand is placed in different locations until the lowest dip in the compartment is found. The upward stem can be hand bent in the field to any shape for easy securing, in this case four tie wrap mounting blocks were used to permanently secure this device. Today, the shore cords are stored in this compartment.

This is the aft most watertight compartment on the vessel which goes completely under water in even moderate sea states. With a watertight hatch sealing this compartment, small amounts of water will always find a way in. 

The Arid Bilge Systems nine zone unit lives in this compartment, protecting itself and other items stored here by providing a low humid environment. Three other compartments are also dried in the rudder room and aft compartments.

Four different Arid Bilge Systems have been installed on this vessel for a total of 26 pickup zones.
