Can anyone recognize this painting or artist signature? I found this painting at my Grandmothers about 13 years ago, after she passed away. I guess it is acrylic, as the paint sticks out in many places, like the wave crests. The ships in background look like battle ships possibly? Thank you for any assistance.

(From what I can see of the signature, after it looks like it is initials? It says "TS")
