Roderick Andersen was an English sailor who served as the third mate's steward aboard the Obra Dinn during her last voyage in 1802. He died when a loose cannon broke his neck.
As steward of Third Mate Martin Perrott, Andersen could be seen assisting him. He was first seen walking towards the execution of the Formosan guard Hok-Seng Lau. He was also seen watching three mermaids get taken into the lazarette, alongside fellow steward Davey James.
Some time later, the Kraken attacked the ship. At one point, the Kraken reached through a porthole and grabbed a lit cannon, crushing seaman Abraham Akbar. The cannon fired at Gunner Christian Wolff and seaman George Shirley, who were in front of the cannon's muzzle, shredding them. The recoil broke a cannon loose and detached the barrel from its carriage.
At that moment, Perrott and Andersen ran into the gun deck to investigate, but the Obra Dinn heeled to starboard because of the Kraken's pull. The cannon barrel fell on Andersen and crushed his neck against the wall behind him.
Andersen can be identified in The Doom, part 2, where he is seen walking next to Third Mate Perrott in the direction of the latter's cabin, carrying plates of food. Bringing food to the officer they serve is a task of the steward, and Perrott's presence shows clearly which officer Andersen is assigned to.
Andersen appears in few memories. In Unholy Captives, part 2, he appears talking to fourth mate's steward Davey James, implying their similar occupation. His body is among the few that remain on the Obra Dinn when she drifts back into port, probably because nobody wanted to lift the cannon off of him.
