The BDC Trieux in French Polynesia in 1971-1972

The job of the BDC Trieux and of the other two BDCs in Tahiti was to transport all kinds of goods to support the Centre d'expérimentation du Pacifique that was conducting nuclear tests on the atoll of Moruroa.

There were two main destinations: the atoll of Hao that was the support base at 500 nautical miles from Tahiti, and the atoll of Moruroa at 280 nautical miles of Hao.

Hao is a fairly close atoll with a very narrow pass on the north side. Although the tides are not very big in the South Pacific (35 cm or less), the current in the pass may be quite strong because of the size of the lagoon. So, the Trieux needed to enter the lagoon only when the current was not too strong in either direction.

There was an airstrip on Hao so that military airplanes could transport people and urgent packages.

When in Hao, the Trieux would be anchored from its bow and have its stern on a wharf so that goods could be loaded or unloaded easily.

The atoll of Moruroa was much more open, so there was no problem of current to enter the lagoon.
Like Hao, there was an airstrip and a wharf.

We would also transport some goods to various small atolls, either in support of military posts or to deliver big items to local inhabitants.

On these small atolls, there was no way to dock or to anchor. So, the Trieux would stay outside of the atoll, going at low speed to be still able to maneuver, and the goods would be delivered by cargo-sling by one or two helicopters.

For very heavy or voluminous items, we would use what was called "baleinières" (whaleboat) that were staffed by Tahitians (the "baleiniers") that knew how to go over the coral reef with the swell.

For really voluminous items, such as a truck or a concrete mixer, the baleiniers would attach two baleinières together to make a "baleinière double" and would go over the coral reef.
