# SUPPLEMENTARY INFORMATION:

 

## Background and Purpose

The offshore supply vessel BLN HULL 563 will be used for offshore supply operations. Full compliance with 72 COLREGS and Inland Rules Act will hinder the vessel's ability to maneuver within close proximity of offshore platforms. Due to the design of the vessel, it would be difficult and impractical to build a supporting structure that would put the side lights within 5.6′ from the greatest breadth of the vessel, as required by Annex I, paragraph 3(b) of the 72 COLREGS and Annex I, Section 84.05(b) of the Inland Rules Act. Compliance with the rule would cause the lights on the supply vessel BLN HULL 563 to be in a location which would be highly susceptible to damage from offshore platforms. The supply vessel BLN HULL 563 cannot comply fully with lighting requirements as set out in international regulations without interfering with the special function of the vessel (33 U.S.C. 1605(c); 33 CFR 81.18).

                    Locating the sidelights 12′-4                    1/4                    ′′ inboard from the greatest breadth of the vessel on the pilot house will provide a shelter location for the lights and allow maneuvering within close proximity to offshore platforms. In addition, the forward masthead light may be located on the top forward portion of the pilothouse 38′-2                    1/4                    ′′ above the hull. Placing the forward masthead light at the height required by Annex I, paragraph 2(a) of the 72 COLREGS would result in a masthead light location highly susceptible to damage when working in close proximity to offshore platforms. Furthermore, the horizontal distance between the forward and aft masthead lights may be 18′-10                    9/16                    ′′. Placing the aft masthead light at the horizontal distance from the forward masthead light, as required by Annex I, paragraph 3(a) of the 72 COLREGS, and Annex I, Section 84.05(a) of the Inland Rules Act, would result in an aft masthead light location directly over the aft cargo deck where it would interfere with loading and unloading operations. Lastly, the aft anchor light may be placed 25′-1                    5/16                    ′′ off centerline to the starboard side of the vessel, just forward of the stern. Placing the aft anchor light directly over the aft cargo deck would interfere with loading and unloading operations.                

The Certificate of Alternative Compliance allows for the placement of the sidelights to deviate from requirements set forth in Annex I, paragraph 3(b) of 72 COLREGS, and Annex I, paragraph 84.05(b) of the Inland Rules Act. In addition, the Certificate of Alternative Compliance allows for the vertical placement of the forward masthead light to deviate from requirements set forth in Annex I, paragraph 2(a) of 72 COLREGS. Furthermore, the Certificate of Alternative Compliance allows for the horizontal separation of the forward and aft masthead lights to deviate from the requirements of Annex I, paragraph 3(a) of 72 COLREGS, and Annex I, Section 84.05(a) of the Inland Rules Act. Lastly, the Certificate of Alternative Compliance allows for the placement of the aft anchor light to deviate from the requirements of Rule 30(a)(ii) of 72 COLREGS and Rule 30(a)(ii) of the Inland Rules Act.

This notice is issued under authority of 33 U.S.C. 1605(c), and 33 CFR 81.18.

Dated: May 15, 2009.
