Though this may not sound very hard, a ship collision with an iceberg would surely end in disaster. The enormous momentum involved and potentially huge contact area with the ice can generate hundreds of tonnes of force on the hull which would cause it to dent and crumple. This is a frequent occurrence along the coast where icebergs are brought into shore by irregular tidal currents or strong winds. The Grand Banks are criss-crossed with old and new iceberg scour marks. Icebergs are comprised of pure fresh water.
Iceberg ice is quite safe to consume.
In short, the answer is no. When a piece of iceberg ice and a piece of freshwater ice are the same size, shape and temperature they will melt at around the same rate. A small experiment in which this was demonstrated actually showed that a block of tap water ice outlasted a similar iceberg ice block by 10 minutes over 30 hours. Icebergs have sheltered vessels in storms, towed sailing ships against the wind and cleared paths in sea ice for mariners. The sound comes from the popping of compressed air bubbles which are in the ice.
