33. Power Plant

This is another substantial concrete building that was the location of the generators for the power used by the seaplane base and ancillary activities. Other buildings in this area were of timber construction and only the foundations remain.

34. Aircraft bunker

This is a large rectangular (concrete lined) bunker, about 30 metres x 30 metres x 7 metres in height that is situated in the hills above the seaplane base that was used to store aircraft and later their munitions. Chuukese labourers utilising only picks and shovels dug it out over a 12 month period in about 1938/39.

35. Underground fuel storage tanks

Two, 650 gallon aviation gasoline tanks were located underground in the hills above the seaplane base. The gasoline was fed by pipe to the seaplane base.

36. Kokuso Dock

At the end of this dock is a large crane that was used to handle the unloading of cargo from the lighters, including boxes containing aircraft. They were assembled in nearby workshops. The crane was pushed off its mount after the war during salvage operations.

37. Main 'Oil' Dock

This dock extended a further 50 metres when it was in operation during the war. It was used by lighters to refuel the larger Navy and Merchant ships with oil and gasoline at their various anchorages. It was rebuilt in about the 1980s to serve Japanese tishing fleets and a fish processing factory was established here. The dock to the west was used to supply coal for use by steam vessels. The dock to the east of the main dock was used to supply water to the ships.

38. Fuel Tanks

As would be expected there were many fuel / oil tanks that were required to fuel ships. The underground 10,000 ton oil tank that was hit during the bombing, now contains the island water storage. Two other above ground, riveted, steel plate 10,000 ton fuel tanks (about 50 metres in diameter and 20 metres in height) are located nearby and one is considerable buckled from being hit with bombs and the resulting fires.

39. Navy Supply office and warehouses

Concrete foundation remains for the Navy Supply offices and warehouses. There is also a boiler and bath associated with a residence for Navy personnel.
