The liferafts were launched partly by crew members and passengers and partly by automatically release and inflation when the vessel sank. The rafts were found very difficult to use in the severe sea conditions partly for the following reasons:
Many rafts capsized due to the wind pressure and drifted upside down, and many did not fully inflate.
Some of the upside-down drifting rafts were later righted by the waves . When this happened, however, those who were on the raft were again thrown into the sea and had great difficulties in climbing back.
Capsized rafts with the canopy under water provided no shelter for those on board.
The canopies of the rafts did not raise themselves automatically, and the openings could not be closed properly.
Much water accumulated on the bottom of the rafts. In the worst case reported, there was 20 cm of water on the bottom of the raft. The bale scoops were so small that they were ineffective, and many survivors used their shoes to bale with.
The knives on board the rafts proved to be useless.
When the rafts were drifting the various lines for inflation and for keeping the raft in position for boarding constituted obstacles for people trying to board. The rope ladder went underneath the raft, swinging the feet of those who were trying to climb on, and thus affording practically no help.
The operating head was not properly tightened to the CO2 pressure cylinder in many rafts found after the accident. This may be a reason why many rafts were not fully inflated.
Entangled painter lines were also found around the operating heads.
As mentioned earlier the liferafts had no individual identification and were therefore not distinguishable. The helicopter crews and the mariners were unable to keep track of which rafts had already been searched. Many are believed to have been searched many times, thereby delaying the search of others.
Another problem was that the black colour of the liferafts' bottoms made the rafts difficult to detect when floating upside down.
Examination of the recovered liferafts shows that almost all the drift anchors and their ropes were missing. Likewise, many emergency packs were missing. The missing equipment may have been lost during the rescue operation or later.
Liferafts were under these circumstances useful rescue equipment but the serious deficiencies listed above diminish their value in heavy seas and when people have to climb into them from the water.
