ABSTRACT

This report contains the results of the inspection of 24 fleet moorings locatedwithin the Naval Station San Diego, California, harbor complex. A CHESNAVFAC-ENGCOM-assigned Engineer-in-Charge and divers from Underwater Construction TeamTwo conducted the inspection from 23 to 28 July 1984.

Of the 24 moorings inspected, 14 were found to be in good condition, 7 in faircondition, and 3 unsatisfactory for fleet use. A summary of these results iscontained in Annex A.

Of the seven moorings in fair condition, four are recommended for downgradingto the next lower mooring classification. The remaining three have oversizedchain and are, therefore, still in satisfactory condition for continued use intheir current capacity. Five moorings required reclassification to their prop-er design class.

Detailed information and specific comments concerning each of these moorings

are included within this report.

UNDERWATER INSPECTION REPORT

1.0 INTRODUCTION

1.1 Background. Under the COMNAVFACENGCOM Fleet Mooring Maintenance (FMM)

Program, CHESNAVFACENGCOM has been assigned the responsibility to plan and con-

duct periodic diver inspections of all fleet moorings worldwide. In carrying

out this responsibility, CHESNAVFACENGCOM designated an Engineer-In-Charge (EIC)

to provide inspection planning and onsite technical direction for the underwater

inspection of fleet moorings at PWC San Diego. The actual underwater portion

of the inspection was performed by divers of Underwater Construction Team Two

(UCT TWO). The positions of the 24 fleet moorings inspected at PWC San Diego

are shown in Figures 1 and B-I. The inspection was conducted from 23 to 28

July 1984.

1.2 General Description of Moorings. The following classes of fleet moorings

were inspected at PWC San Diego:

2.0 INSPECTION PROCEDURES

2.1 Inspection Objectives. The purpose of the mooring inspections was to de-

termine the general condition of the buoys and chain assemblies, and, when

possible, to verify or update existing as-built and maintenance records. Divers

inspected only a portion of the submerged buoy hull and chain assemblies in

order to compile a general description of the mooring's condition. The exist-

ence of fairly consistent measurements during this inspection provides a good

indication of the mooring's overall condition. It should be kept in mind that

periodic underwater inspections are intended as an expedient and relatively

inexpensive supplement to accurate maintenance records.

2.1.1 Chain Wire Diameter Measurements. Chain wire diameter measurements are

used to evaluate the condition of a mooring. A selective sampling of the wire

diameter of chain links an(. connecting hardware was taken in order to determine

the amount of deterioration due to corrosion and wear. At each sampling area,

the chain was cleaned to bare metal. Single-link measurements were taken where

the chain was slack to detect corrosion loss. Double-link measurements were

taken where two links connected under tension to detect the combined effects of

corrosion and wear. Chain links and other components which measured 90 percent

or greater of original wire diameter are considered to be in "good" condition;measurement between 80 and 90 percent of original diameter is considered "fair..

condition and is cause for the mooring to be downgraded in classification; anymeasurement less than 8D percent is considered "poor" and is cause for the

mooring to be declared unsatisfactory for fleet use.

2.1.2 Inspection Limits. Standard underwater inspection procedures do not callfor the inspection of any part of the mooring which has been buried or which is

below a water depth of 130 feet if scuba gear is used. Anchor chain and riser

subassemblies were observed only to the point at which they became buried; no

attempt was made to locate and inspect anchors or other mooring materials which

were not readily visible.

2.2 Buo.

2.2.1 Buoy Topside. Each buoy was inspected to determine its general condition.

The buoy markings were checked for conformance to those noted in applicable

charts. Physical damage, such as holes, dents, or listing, was described. Hatch-

es openings, and penetrations were examined and worn material and rust were

reported. The buoy fenders and chafing strips were checked for integrity and

secure connection to the buoy. Buoy top jewelry was measured with calipers to

find the overall outside dimensions and areas of most severe reduction in wire

size.

5

2.2.2 Buoy Lower Portion. Divers inspected the buoy below the waterline andrecorded the thickness of marine growth and the condition of the buoy bottom.

2.3 Riser Subassembly. To determine chain wear, each riser chain was inspectedby taking three consecutive double-link measurements, using pre-cut gauges and!

or calipers, at both ends and at the center of the riser. To determine orig-

inal chain size, divers took single-link measurements of the wire diameter andmeasured the link length (link length should be six times the wire diameter).

2.4 Anchor Chain Subassemblies. Using pre-cut gauges and calipers, UCT TWOdivers took sample measurements of the anchqr chain subassemblies.

3.0 INSPECTION SUMMARY

An in-depth duscussion of the inspection results is contained in Annex A.

Annex 8 contains buoy survey data and Annex C a copy of the preliminary report ofthe inspection results. A detailed evaluation of the information and datagathered during the inspection revealed the following:

o Of the 24 moorings inspected, 14 were found to be in good condition,7 in fair condition, and 3 unsatisfactory for fleet use. A summary

of these results is contained in Table 1.

o The three moorings in unsatisfactory condition are CM-i, DM-5, and T-1.CM-i has one anchor that is not set in the bottom and its buoy is in

poor condition and in need of overhaul. Anchor chain subassembly Cof mooring DM-5 is worn to less than 80 percent of its original wirediameter. T-1 has an anchor on the bottom surface.

o Mooring DM-3 has a detachable link worn to less than 80 percent and

j) should be downgraded to a Class E mooring.

o Although mooring DM-G is generally in good condition, the cause of itsbuoy listing about 30 degrees should be determined and corrected as soon

as possible.

6

o Anchor chain subassemblies of both moorings FM-48 and FM-49 are worn

between 80 and 90 percent. These moorings should be downgraded to Class

C moorings.

0 Due to riser and anchor chain subassembly wear, mooring P-1 should be

downgraded to a Class D mooring.

o The riser chain subassembly is worn between 80 and 90 percent in mooring

T-2. However, due to oversized chain, this mooring is in satisfactory

condition for use as a Class E mooring.

o Moorings DM-6, DM-8, DM-9, FM-19, and FM-21 should be reclassified to

Class A moorings because of chain size. In addition, moorings DM-8 and

FM-21 should be further downgraded to Class B moorings because of riser

or anchor chain subassemblies being worn to between 80 and 90 percent.

o Only six of the moorings (FM-19,- 48, -49, -50 and -51; and K) were

observed to have some form of cathodic protection.

INSPECTION REPORT."

A-1

MOORING CM-i

Buoy. This is a peg-top buoy with a 10-foot diameter. Its freeboard measures

3 feet. The topdeck and sides are severely rusted and pitted. The buoy's top

jewelry is severely corroded, and its wood chafing strip and upper fender are

in poor condition. The lower fender is completely deteriorated. The overall

condition of this buoy is poor.

Riser Chain Subassembly. The riser chain is in good condition with all chain

measurements greater than 90 percent of original wire diameter. The ground

ring is buried.

Anchor Chain Subassembly. Not visible for inspection. However, what appears

to be a 5,000 pound anchor was observed on the bottom under the buoy.

Conclusions/Recommendations. This mooring is unsatisfactory for fleet use. Its

buoy is in poor condition and an anchor is visible on the bottom. This mooring

should be removed from the service and overhauled at the earliest practical

time.

MOORING DM-3

Buoy. This is a 12-foot-diameter drum-type buoy with a 4-foot freeboard. It

has a single combination fender/chafing strip which covers the junction of the

top deck and sides. There is some light rust at the waterline and 4 to 5

inches of marine growth on the bottom. Overall the buoy is in satisfactory

condition.

Riser Chain Subassembly. The riser chain is in good condition with all measure-

ments greater than 90 percent of its original wire diameter. The ground ring

was located at a depth of 35 feet, about 5 feet above the bottom.

Anchor Chain Subassemblies. The visible upper section of the three chain sub-

assemblies is in good condition. All measurements of the chain were above 90

percent. However, a NACO detachable link in subassembly B has loose pins and is

worn to about 75 percent of its wire diameter.

Conclusions/Recommendations. Although a detachable link in anchor subassembly

B is worn to less than 80 percent, this link is oversized and is still satisfac-

tory if the mooring is downgraded to a Class E. However, this link should be

replaced during the next scheduled overhaul.

Buoy. This is a 12-foot-diameter drum-type buoy with a 40-inch freeboard. It

has a single wood combination fender/chafing strip covering the junction of the

top deck and sides. A second wood fender near the bottom of the buoy is in good

condition. The buoy's bottom has 4 to 5 inches of marine growth, and its top

jewelry is lightly rusted.

Riser Chain Subassembly. The riser chain is in good condition with all single-

and double-link measurements above 90 percent. The ground ring was located at

a depth of 40 feet and is in good condition.

Anchor Chain Subassemblies. Only 5 feet of the three subassemblies was visible

before the subassemblies entered the bottom. Measurements of the upper 5 feet

of each of the chains were greater than 90 percent.

Conclusions/Recommendations. This mooring is in satisfactory condition for con-

tinued use as a Class 0 mooring.

Buoy. This is a 10-foot-diameter drum-type buoy with a combination wood fender/

chafing strip covering the junction of the top deck and sides. Its bottom is

covered with about 3 inches of marine growth. The top jewelry is lightly

rusted. In general, the buoy is in good condition.

Riser Chain Subassembly. The riser chain is in good condition with both single-

and double-link measurements greater than 90 percent. The ground ring was io-

cated at a depth of 26 feet and was found to be pitted.

Anchor Chain Subassemblies. Subassemblies A and B are in good condition with

all chain measurements greater than 90 percent. Subassembly C, however, is of

nonstandard construction in that there is no leg chain. From the ground ring

down, there is a 2 1/4-inch NACO detachable, a 2 1/4-inch detachable link, and

a 3-inch end link which is shackled to the anchor. The anchor is almost di-

rectly below the buoy. In addition, the NACO detachable link is worn to about

50 percent of its original wire diameter.

Conclusions/Recommendations. Due to the extremely worn NACO link in subas-

sembly C, this mooring is in poor condition and unsatisfactory for continued

fleet use. This mooring should be kept out of service until Lis link is

replaced.

In addition, Table 7-62 on page 26-7-285 of DM-26 dictates that a Class D riser

type mooring in 35 feet of water requires nine shots of 2-inch ground leg chain,

or three shots per leg. Subassembly C should be replaced with a properly con-

structed chain leg at the earliest practical time.

good condition. Single- and double-link measurements were all greater than 90

percent. The ground ring is buried.

Anchor Chain Subassemblies. None installed. The riser chain is connected to

a stake pile.

Conclusions/Recommendations. This mooring is in satisfactory condition for

continued fleet use. However, because of the 2 3/4-inch chain, this mooring

should be reclassified as a Class A mooring.

MOORING DM-8

Buoy. This is a 12-foot-diameter peg-top buoy with a 62-inch freeboard. The

top jewelry is in poor condition, and the tension bar top eye has a 3/16inch-

wide by a i-inch-deep crack extending for 16 inches along its top. This crack

was previously reported as a result of the 1982 underwater inspection. The

buoy has two wooden chafing strips and two wooden fenders. These are in good

condition except for the lower fender which is badly deteriorated. The buoy

has moderate rust on its sides and 2 to 3 inches of marine growth on its bottom.

Riser Chain Subassembly. The riser chain is in fair condition with measure-

ments near its mid-section down to 80 to 90 percent of its original wire diam-

eter. The riser enters the bottom and reappears near a 12-inch by 12-inch "H"

pile with 1 1/2-inch flanges.

Anchor Chain Subassemblies. None installed. The riser chain goes directly to

an "H" pile in the bottom.

Conclusions/Recommendations. Due to its 2 3/4-inch riser chain, this mooring

should be reclassified to a Class A mooring and downgraded to a Class B because

of its worn chain. However, since its design does not fall into any standard

mooring classification, no estimate of its holding capacity is available. The

mooring should be used with caution.

The top jewelry should be examined and, if necessary, replaced. Immediateaction should be taken to repair the crack in the tension bar top eye.

seven ground legs but no anodes were observed. Underwater voltmeter readings

measured the cathodic protection on the seven legs to be between -.77 and -.65

volts. There were no anodes on the buoy.


continued fleet use. However, because of the 2 3/4-inch chain in the riser,

this mooring should be reclassified as a Class A mooring. In addition, the

buoy should be overhauled.

Buoy. This is a 16-foot-diameter non-riser (telephone type) buoy with eight

legs. Each of the buoy's bottom four padeyes has a 3 1/4-inch pear link attached

to it. Two 2 1/2-inch ground legs are connected to each pear link. The buoy

has a 3 1/2-foot freeboard, a wood chafing strip, and a single wooden fender

(partially missing).

Anchor Chain Subassemblies. All eight of these subassemblies are in good condi-

tion, and the single- and double-link measurements of each leg were greater

than 90 percent of its original wire diameter. About 1 to 2 inches of marine

growth was observed on the anchor chain. Assemblies E and F cross each other

and appear to run out in a similar direction. Legs G and H are on top of each

other and disappear into the bottom on the same bearing.


continued fleet use. However, its leg orientation appears questionable.

Buoy. This is a 12-foot-diameter peg-top buoy which has a 45-inch freeboard.

It has two wooden chafing strips and a wood fender in good condition. A second

wood fender, the lower one, is about 80 percent deterioriated. The buoy has a

heavy coating of rust on its sides.

Riser Chain Assembly. The 2 3/4-inch riser chain is in good condition. Single-

and double-link measurements were greater than 90 percent of original diameter.

The ground ring is in good condition and was located at a depth of 35 feet.

Anchor Chain Assemblies. Seven legs are attached to the ground with NACO

detachable links, pear links, and other types of detachable links. The 2 1/2-

inch anchor chain is in good condition with all measurements greater than 90

percent of its original diameter.

Conclusions/Recommendations. As a result of this inspection, this mooring ap-

pears to be in good condition. However, during the previous inspection, specific

parts of anchor chain subassemblies 4 and 7 were measured to be between 80 and

90 percent (fair condition) of their original diameter. Because of the 2 3/4-

inch chain in the riser, this mooring should be reclassified as a Class A moor-

ing and downgraded (because of chain wear) to a Class B. The buoy should

be refurbished.

two wooden fenders. The upper is in good condition, but the lower is complete-

ly deteriorated. Two wooden chafing strips on the buoy's top deck are in good

condition. There is a light coating of rust on the buoy's sides.

Riser Chain Subassembly. The riser chain is in good condition with single- and

double-link measurements all greater than 90 percent. There is about 2 inches

of marine growth on the chain. The ground ring was located at a depth of 28 feet.

Anchor Chain Subassemblies. Most sections of the four subassemblies are in good

condition. However, the lower sections of subassemblies A and C were measured to

be between 80 and 90 percent of the original 2 1/2-inch wire diameter. Each of

the subassemblies was visible for about 20 feet before it entered the bottom.

Cathodic Protection. Continuity wire was observed on all legs, but no chain

anodes were visible. Underwater voltmeter readings measured the cathodic pro-

tection to be between -1.01 volts at a buoy anode to -.64 volts on anchor chain

subassembly C.

Conclusions/Recommendations. Due to the 80 to 90 percent measurements on two

of the ground legs, this buoy is considered to be in fair condition and should

be downgraded to a Class C mooring.

MOORING USS McKEE

This is a Mediterranean type mooring that has no mooring buoys or risers in-

stalled. It has four bow and two stern anchor chain subassemblies. Each of

the bow subassemblies is attached to a marker (pick up) buoy with a 1 1/8-inch

riser chain. Although there are four bow anchor chain assemblies available,

McKEE only uses two (see sketch on attached diver report sheet).

Anchor Chain Subassemblies (Bow). These two subassemblies ace in good condition

with single- and double-link measurements greater than 90 percent of their origi-

nal wire diameter.

Anchor Chain Subassemblies (Stern). The two stern subassemblies are also in

good condition with measurements greater than 90 percent of original wire diam-

eter.

Riser Chain Subassemblies (Marker Buoys). The four marker buoy riser chain sub-

assemblies are in poor condition due to severe corrosion and wear. Most measure-

ments of all four of these riser chains were less than 80 percent of their orig-

inal 1 1/8-inch diameter.


continued use by fleet units. Although the poor condition of the marker

buoy chain does not affect the holding capacity of the mooring, this chain

should be replaced.
