Second hand materials, machinery, appliances and items may be used subject to the specific agreement of the society and the owner. The requirements for the selection of materials to be used in the construction of the various parts of a ship, the characteristics of products to be used for such parts and the checks required for their acceptance are to be as stated in part C of the rules and in NR 216 materials, as applicable, or in other parts of the rules or as specified on approved plans.

Proposals regarding remedial actions intended to be adopted to eliminate such defects or unsatisfactory items are to be submitted to the society and, if accepted, carried out to the surveyor’s satisfaction.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
