1.000 SCOPE

This Circular of Requirements (COR) defines the requirements for the Towing, Salvage, and Rescue Ship (T-ATS). T-ATS will be a recapitalization of the retiring Fleet Ocean Tugs (T- ATF) and Rescue and Salvage Ships (T-ARS) capabilities in order to maintain organic Navy 5 towing, salvage, and rescue capabilities.

2.000 DOCUMENTS

The following standards and documents are specified in this COR. While every effort has been made to ensure the completeness of this list, the Contractor is required to meet all specified 10 requirements documents cited in this COR, whether or not they are listed in this section.

Compliance with referenced documents is mandatory even where the referenced document may use terms similar to “recommendation”, “guideline” or “guidance” in their title or text.

Order of precedence - In the event of a conflict between the text of this document and the references (other than Regulatory Body requirements) cited in this document, the text of this 15 document takes precedence. First tier references take precedence over sub-tier references in the event of a conflict. Nothing in this document shall supersede applicable laws and regulations unless a specific exemption has been obtained.

Silence of one document with respect to details or requirements in another document shall not be considered an inconsistency. 20

Effective issue - Where first tier references, such as industry standards, are referred to, the issue or revision/amendment in effect at Detail Design and Construction Contract Award shall apply.

First Tier and Sub-tier Reference - Any referenced document that is directly cited for use or application by an identifying number or name in this COR is a first tier reference for each 25 particular use or application for which it is so cited. Any document that is cited in a first tier reference, or in a document referenced therein, is a sub tier reference. A document that is a sub-tier reference in one application may also be a first tier reference in another application when it is cited directly.

The terms ’as approved,’ ’to approve’, ‘approved’, ’as required’, and ’required’ mean the approval by, the requirements of, or the selection of the Government. Additionally, the terms ’approved’ and ’required’ may also mean approved or required by a Regulatory Agency or Regulatory Body. Wherever these terms are used without further qualification, it is the approval, 25 decision, or direction of the Government or Regulatory Bodies, as appropriate that is required.

Approximate: Where the term “approximate” or “approximately” is used, it means that delivered performance, parameter, or characteristics shall be within 10% of the specified value, except where an upper or lower bound on the specified value is provided.
