* **Revision Details:**
* The present safety fairway was revised after discussion with stakeholders, considering navigational safety, traffic flow, and avoidance of survey/exploration areas.
* The revised routing measure (Traffic Separation Scheme) supersedes the previous safety fairway established by MS Notice 15 of 2008.
* **Implementation:**
* The revised routing measure coordinates are incorporated into INT Chart No. 7334 (Annexure - II), which is for informational purposes only and not for navigation.
* The MS Notice comes into effect on 01.02.2018.
* **Enclosures:**
* Annexure - I; INT Chart No. 7334 (Not to be used for navigation)
* Annexure - II; Coordinates of the routing measure (Traffic Separation Scheme)
**Impact Analysis**
**Stakeholder: Mariners and Shipping Companies**
* **Impact:** Mariners and shipping companies are impacted by the new safety fairway and traffic separation scheme at the approaches to Mumbai.
* **Action Required:** Mariners and shipping companies should adhere to the revised routing measures (Traffic Separation Scheme) detailed in the notice and incorporated in INT Chart No. 7334 after 01.02.2018.
