USS GERMANTOWN Survey Summary
WB Tank 6-56-1-W - Severe corrosion breakdown, stiffeners with thinned edges. Recommend blast, renewal of
wasted steel, re-coat tank.
WB Tank 6-43-1-W - Thinned and wasted stiffeners. Recommend renewal.
WB Tank 6-52-1-W 6 52 1 W - Wasted overhead stiffeners stiffeners. Recommend renewal renewal.
WB Tank 6-70-2-W - Heavily wasted overhead stiffeners, transverse bulkhead stiffeners, longitudinal bulkhead
stiffeners, poor coating condition, poor outfitting condition. Recommendations have been
addressed during availability.
WB Tank 6-74-1-W - Tank blasted and coated, holes in stiffeners and plating coated over.
Recommend repair wasted structure.
WB Tank 6-85-4-W - Tank blasted and coated, holes in stiffeners and plating coated over.
Recommend repair wasted structure.
WB Tank 6-101-1-W - Fair coating condition with thinned and wasted transverse bulkhead stiffeners and wasted
overhead longitudinal stiffeners. Recommend repair structure.
WB Tank 3-93-1-W - Poor coating condition, thinned and wasted bulkhead stiffeners and poor condition of the
outfitting in the tank. tank Recommend repair structure structure.
WB Tank 2-107-3-W - Fair coating condition however rated poor due to wastage in way of the
overhead longitudinal stiffeners, holed out deck plating in way of the longitudinal bulkhead
vertical stiffeners and poor condition of the outfitting within the tank. Recommend repair
structure.
WB Tank 5-115-1-W - Fair coating condition, however rated poor due to wastage in way of the overhead
longitudinal stiffeners, after transverse bulkhead vertical stiffeners, and holed out
overhead plating. Recommend repair structure.
WB Tank 5-125-1-W - Poor to fair coating condition however rated poor due to wastage in way of the overhead
longitudinal stiffeners. Recommend repair structure.
Foundations Under - Severely wasted. Renewal required.
A/C Plants
AC Machinery – Tank tops with holes and thinned plate, only minor repairs made in way of holed tank top.
Recommend wasted tank top be renewed.
If this were a commercial vessel and these critical deficiencies were corrected,
ABS would feel confident classing the ship 16
Germantown Initial Results
� Outstanding support from Crew, CLASSRON
and RMC
� Survey identified areas requiring attention
� Analysis demonstrated the following:
• Initial structural design well-conceived
• Structured survey plan necessary to achieve expected
service life
� Developed tools will facilitate analytically-based future
maintenance planning
