About this file

Written by GovTribe AI ·

This document includes engineering drawings and calculations for the placement of sacrificial anodes on a floating barge pier to be constructed for McMurdo Station in Antarctica under solicitation number W912BU-23-B-0016 issued by the U.S. Army Corps of Engineers Philadelphia District. The drawings specify installing approximately 12 metric tons of aluminum anodes on the barge's bottom structure to prevent corrosion over its anticipated 10-year service life. The 328-foot by 100-foot by 18-foot barge will be uninspected but classed by the American Bureau of Shipping with notations for deck cargo and anticipated air and sea temperatures.

1. THE INTENT OF THIS DRAWING IS TO SHOW THE ARRANGEMENT OF SACRIFICIAL ANODES ON THE

HULL BOTTOM STRUCTURE FOR THE MCMURDO STATION BARGE PIER.

2. THE BARGE IS TO BE UNINSPECTED.

3. THE BARGE WILL BE CLASSED FOR ABS NOTATIONS ✠A1, DECK CARGO BARGE AND A -29°C

DESIGN AIR TEMPERATURE AND A -1.9°C SEA WATER TEMPERATURE.

4. APPROXIMATELY 12 MT OF ALUMINUM ANODES ARE REQUIRED.

5. THE MAXIMUM REPLACEMENT INTERVAL IS 10 YEARS. ANODES MUST BE MONITORED ON A

REGULAR BASIS AND REPLACED AS NECESSARY WITHIN THE 10 YEAR CYCLE. HANGING ANODES

MAY BE USED TO EXTEND PERIOD BETWEEN REPLACEMENTS.

6. ALL WELDING, MATERIALS, AND PROCEDURES SHALL COMPLY WITH APPLICABLE ABS RULES.

7. ANODES SHALL BE ALIGNED WITH THEIR LONG AXIS PERPENDICULAR TO CENTERLINE. ANODES

SHALL BE PLACED ON THE FLAT BOTTOM ONLY.

8. ANODES ARE THE ALUMINUM WELD-ON TYPE. ENSURE GOOD CONTACT BETWEEN THE ANODE

AND HULL.

9. ANODE LENGTH SHALL BE AT LEAST 4 TIMES THE WIDTH.
