Games like AHTS Ship Simulator

Captain, command a 3000 ton anchor handling and tug supply (AHTS) vessel and navigate it in high seas to a nearby oil rig. You control it with powerful main engines and side thrusters. Two outside water cannons help against a UFO with a tractor beam and fires that make your mission difficult. Set your weather and make sure not to collide with traffic or the rig. Have fun, Captain
