4.2 ASSEMBLY AND INSTALLATION GUIDE

The Subsea Feeder must be assembled in an area that can accommodate the full diameter of the

sinker tube (Ø = 5.5 m).

Once assembled, use a crane or similar capable of safely lifting the cyclone and main pipe to

move the AKVA Subsea Feeder to the pen. The top and bottom parts must be flanged together

with bolts tightened to a torque of 12 Nm.

Procedure:

1. Attach the top and bottom sections of the distribution chamber together using flange bolts

tightened to a torque of 12 Nm.

2. Attach the hose between the pump and the distribution chamber using hose clamps. Use

tape to attach the hose to the branching pipe.

3. Tape the cable from the pump and riser pipe to the main pipe.

4. If an underwater light and/or camera is attached to the unit, cables shall be taped to the

riser pipe and pump cable.

5. Tie 4 loading straps around the main pipe and drape them over the floating collar.

6. Follow-up inspection before placing the AKVA Subsea Feeder in the cage:

Check the unit for surface cracks, other potential damage and sharp edges.

Make sure all hoses and cables are properly attached/taped to the unit/main pipe.

Ensure the feeding hose is properly attached to the cyclone.

The loading straps to moor the unit must be properly tied around the main pipe and

draped over the floating collar.

7. Measure 30 cm in from the end of the hose and mark that spot. Slide the hose 30 cm into

the opening on the side of the cyclone. Make sure to attach the hose properly. The inlet on

the cyclone fits a 90 mm feeding hose.

8. Attach a 20 mm rope to each of the four straps. Rope length shall be from end of lifting strap

to pen and attachment around the pen edge with 1 m slack in each direction.
