At 07.20 hours on 23 June 1942 the Andrea Brøvig (Master Selmer L. Pedersen) was hit by two torpedoes from U-128 off Trinidad. The tanker stopped and was hit amidships by a coup de grâce at 07.40 hours. To set the tanker on fire the U-boat opened fire with the 37mm AA gun but then had to fire a second coup de grâce that hit aft and caused the ship to sink by the stern within 3 minutes.

The survivors later reported that the U-boat fired on the lifeboats with machine guns, but missed - it is more likely that some shots fired at the tanker hit the water near the boats and the men thought they were the target. On 25 June, they reached Tobago and Trinidad and later boarded Robert E. Lee, which was sunk by U-166 (Kuhlmann) en route to New Orleans with 268 passengers (mostly survivors of other sinkings) on 30 July. All Norwegian passengers were saved.

The engineers from Andrea Brøvig worked later on the Norwegian motor merchant Balla (2565 grt), which was equipped with two German diesel engines from 1930, a type meant for U-boats. This vessel had to be laid up in the USA during 1942 due the continued problems with her engines, but the engineers from the tanker kept them running.
