Design of a hole to be made in a sea chest for a ship

Hello there! I'm looking for a talented Freelancer to help design a large hole in a steel sea chest for a ship. As requested, the diameter of the hole should be greater than 8 inches and there are no special design considerations or requirements to take into account. If you have experience with such projects and can get the job done as desired, I would appreciate an offer. Thank you for your time!
