(CNN) A crew member who survived the deadly Conception diving boat fire off the coast of California is suing the vessel's owners, saying the staff had not been properly trained.

Ryan Sims had been working as a steward on the Conception for about three weeks when the vessel was consumed by flames and 34 people on board were killed

In a lawsuit filed last week, Sims says Truth Aquatics, the company that owns the Conception, was negligent because they failed to properly train crew members, did not provide adequate safety and medical equipment and failed to inspect the vessel, among several other claims. The document only provides a list of claims but does not provide specific details on them.

The suit also names Truth Aquatics owner Glen Fritzler and Worldwide Diving Adventures as defendants, the document shows.

The vessel was owned by Truth Aquatics and had been chartered by Worldwide Diving Adventures.
