No. 1, 2 and 3 tunnel thrusters, SW cooling pumps, Central coolers, FW cooling pumps, emergency fire pump and
provision refrigeraon plant.
WT Compartment no. 2
No. 4 and 5 retractable azimuth thrusters.
WT Compartment no. 3
Air condion chillers and forward electrical load centers including forward load 6.6kV / 460V transformers and
converter drives for retractable azimuth thrusters no. 4 and 5.
WT Compartment no. 4
Water generaon and distribuon plant consisng of two reverse osmosis plants and potable / technical water
distribuon systems. The vacuum system and sewage plant are placed in this compartment but separate from the

and lube oil purificaon plant. Both 6.6 kV switchboard and 460 V switchboard are physically divided and placed in
separate rooms located in SB and PS at the upper level in this compartment. Between the two switchboard rooms
the Engine Control room is located. A waterght door gives easy access between the ECR and the EA placed in
compartment 7 and 8.
WT Compartment no. 8
This compartment houses on the lower floor AE no. 5 and ancillary systems such as SW, FW, Fuel & Air and the two
