2) Secure shackle pins with stainless steel mousing/safety wire when deploying buoys. 1-

1/8in. x 6in. diameter buoy rings are believed to be reusable. Replace all 7/8in. shackles used to connect chain to buoy ring.

II. Chain Replacement

1) Replace the entire buoy chain for selected buoys and dispose of existing chain off National Forest Land and in accordance with Federal, state, and local regulations. Existing chains are a full shot (90ft.) in length.

i) Chain to be American Bureau of Shipping (ABS) tested 7/8in. stud link chain, grade 2.

ii) Replacement chain length shall be for the following locations:

• Moser Island--90ft.,

• North Neva--75ft.,

• Sevenfathom Bay--45ft.

2) Replace shackle at the anchor bail with new 1in. hot-dipped galvanized shackle secured with stainless steel mousing/safety wire.

III. Chain Inspection

1) Inspect selected buoy chains by measuring and recording the diameter of the buoy chain links every 10ft. Measurements shall be to the nearest millimeter (mm).

i) 0ft. will be the first link where the chain exits the buoy post with measurements ending at the anchor bail.

ii) Scrape all debris and sea life off the chain links where measurements are taken.

2) Secure any shackle pins that have missing or broken wire with new stainless-steel mousing/safety wire.

IV. Chain Modification

1) Modify the length of chains at two buoys as follows.

i) Lengthen Mud Bay buoy chain with an additional 30ft. of new chain in accordance with

Chain Replacement Specifications (II.1.i). Used chain may be substituted for new if it is the same type and in good condition with all links at least 20mm in diameter.

a. Join chain segments with new 7/8in. hot-dipped galvanized shackle secured with stainless steel mousing/safety wire.

GAOA Sitka Ranger District Mooring Buoy Maintenance Page 4 of 8

ii) Shorten Kanga Bay buoy chain to 45ft. Dispose any excess chain not reused at another buoy off National Forest Land and in accordance with Federal, state, and local regulations.

V. Anchor Replacement

1) Furnish and install new deadweight concrete anchors at two locations. New anchor specifications are shown in Attachment 1. New anchors must be inspected by the Contracting Officer Representative (COR) prior to deployment.

i) Ensure anchor is upright and is not laying on large, submerged stones or bedrock outcroppings.

2) Replace shackle at the anchor bail and connect to existing chain with new 1in. hot-dipped galvanized shackle secured with stainless steel mousing/safety wire.

3) Dispose of old anchor off National Forest Land and in accordance with Federal, state, and local regulations.

VI. Anchor Inspection

1) Measure anchor bail diameter to the nearest millimeter (mm) for concrete anchors.

Measure the thickness (mm) of the two pad eyes on the Fred’s Creek anchor.

i) Scrape all debris and sea life off the bail/pad eyes where measurement is taken.

2) Describe the condition of the anchor bail/pad eyes in writing, i.e. visual estimate of rust, what type of rust, (flaking or tight), etc. If anchor is upside down and bail is inaccessible, note in written report.

i) Scrape all debris and sea life off a 1ft. x 1ft. area around the anchor bail/pad eyes to allow for inspection.

3) For concrete anchors, describe the condition (i.e. is it smooth, is it powdery, is it flaking, etc.) of the concrete in a 1ft. x 1ft. area around one corner of the anchor block.

i) Clean all debris and sea life off a 1ft. x 1ft. area around one corner of the anchor block to allow for inspection.

VII. Anchor Uprighting

1) Reposition anchor in existing location so bottom surface of anchor is contacting the sea floor. If the anchor is sitting on a bedrock outcropping or large submerged stone(s), move to closest location of similar depth where anchor will have maximum contact with softer sea floor material.

VIII. Buoy Replacement

1) Replace existing Moser Island buoy with a spare, government furnished mooring buoy.

Contractor could service Moser Island location last or use the Moser Island buoy as the spare buoy when reconditioning buoys at other locations. Contractor shall dispose of the existing buoy off National Forest Land and in accordance with Federal, state, and local regulations.
