Documentation of damage found in the no. 6 port distilled water tank. Previously discovered buckled floors with a soft curved rolled, slight surface indications found and addressed. Currently being monitored quarterly per annual year to ensure damage does not propagate or progress.

• The Port Engineer Mr. Jeffrey H. Brown and the Chief Engineer was in attendance with the local ABS surveyor and USCG inspectors and a verbal discussion agreed with quarterly monitoring of tank.

• Following report are the documented n.t. floors discovered with slight damage.

This vessel is not in the Alternate Compliance Program (ACP) with the US Coast Guard.

Guidelines for Structural Steel / Outfitting / Piping Assessment criteria were based on ABS rules, Part 7: Survey after construction using substantial diminution and gross defects, survey performed was for targeting steel repairs/renewals.

Inspection grading criteria for the ABS Hull Inspection and Maintenance Program were the guidelines used for criteria of repairs.

The ABS Coating Condition Guide for field surveyors was followed for coating assessment of existing surface coating systems.

ABS minimum wall thickness for steel pipes was followed for tolerance and based repair/s from wall thickness.

SPECIAL INTEREST

AS OF 2012

NO. 6 PORT DISTILLED WATER TANK

Three N.T. Floors were discovered three shipyard special survey prior. Following sketches shows detail and locations of damage and actions performed to ensure detrimental members are within tolerance.

1. NOT TIGHT FLOOR 151 in way of the lightening hole Inboard. Section between the inner bottom tanktop and the bottom plate has a slight soft buckle ≈24" x 18" x 1/2". Adjacent Inner bottom longitudinal stiffener and the bottom longitudinal stiffener along with the vertical flatbar does not have any sign of deflection. Bottom plate in way of the floor does not have any indication of contact or inset. Damaged floor is surveyed quarterly by the Chief engineer to monitor if the damage has any propagation.

Defect/flaws found

- Floor cutout wrap weld to the inner bottom tanktop was fractured 1" outboard of the Inner Bottom

Long'l #1. Fractured was peened and NDE performed, found wrap weld was acceptable and no indication exist.

- Floor Web fractured 1" in way of the cutout radius for IBL #1, not a thru fracture. Fractured was peened and NDE performed found wrap weld was acceptable and no indication exist.

- Floor rat hole snipe wrap weld inboard to the bottom plate was fractured 1-1/4" just outboard of Bottom Long'l #1. Fractured was peened and NDE performed, found wrap weld was acceptable and no indication exist.
