About this file
This document outlines standard specifications for drydocking NOAA ships. The specifications require contractors to furnish all labor, materials, equipment and services to safely dock NOAA ships according to each ship's docking plan. Contractors must inspect hulls for damage and corrosion, check tailshaft and rudder bearings, and submit a preliminary docking report within 24 hours of inspection. While docked, contractors must provide utilities, erect staging as needed, and maintain safe access. Ships must remain out of water until all required drydock work is complete. Contractors are responsible for removing and storing gasoline tanks as required by local fire codes. Appropriate closures and protections must be installed when ships are docked in cold weather. The related federal contract opportunity is solicitation number 1305M223QNMAN0180 for unscheduled drydocking of the NOAA ship REUBEN LASKER from the Department of Commerce National Oceanic and Atmospheric Administration.

NOAA Standard Specification S0700-1
DRYDOCKING OF NOAA SHIPS
1. INTENT
1.1 To drydock the ship in accordance with the following
specifications.
2. REFERENCES
2.1 Ship's Docking Plan, as referred in the detailed
specifications.
2.2 NOAA STD SPEC S0700, Docking Report.
3. GOVERNMENT FURNISHED EQUIPMENT
3.1 None.
4. REQUIREMENTS
4.1 The contractor shall furnish all labor and materials
required to dock and undock the ship in a safe and satisfactory manner and perform the work and associated services, including inspections and reports outlined herein and/or required in the detailed specifications.
4.1.1 The ship shall be lifted in a suitable drydock or
marine railway, in accordance with the ship's docking plan.
Blocks and shoring shall be placed clear of obstructions and so as to support the ship without strain and distortion.
Care shall be taken to haul the ship without list or trim.
The ship shall be docked in the docking position specified by the COTR.
4.1.2 After the ship is hauled, service lines shall be
provided and hooked up to enable the use of the services and utilities in the detailed specifications. Staging shall be erected as required to accomplish the work specified in the detailed specifications. A suitable gangway shall be furnished and maintained to provide a safe access to the ship at all times.
4.1.3 The ship will remain out of the water until all work
required under the detailed specifications which required drydocking has been completed. Upon completion of the underwater work, and approval of the Contracting Officer or designated representative, the ship will be undocked.
4.1.4 During the entire docking and undocking procedure, and while the ship is out of the water, special care shall
Drydocking of NOAA Ships S0700-1 be taken against damage and/or fire.
4.1.5 In undocking the ship, the dock shall be flooded or
the railway lowered, as the case may be, until as many underwater openings as possible are covered without lifting the ship off the blocks. An adequate watch shall be posted to check for leaks. If a leak is reported before reaching this point, the severity of the leak shall be established.
If, in the opinion of the COTR, the leak is not serious, the flooding may be continued to the desired depth to cover other openings and to determine the existence of any other leaks. If leaks are found, the dock shall be pumped down, or the railway raised and repairs made before again flooding. If no leaks occur, upon permission of the COTR, the undocking may continue. Bow and centerline sighting marks shall be provided so the ship may be relanded, if necessary.
4.1.6 Prior to drydocking the ship, the contractor shall
remove all gasoline storage tanks as required by local fire safety regulations. While the tanks are removed, the contractor shall provide safe and adequate storage facilities. After the drydocking is complete, the contractor shall replace the gasoline tanks in their storage racks as original.
4.1.7 When the ship is docked in cold or freezing weather, all sea valves, pipes or similar fittings attached to the hull, shall be drained to prevent freezing and possible cracking.
4.1.8 While the ship is in drydock, all hull openings shall
be secured outside of normal working hours. Blanks shall be fabricated of sufficient strength to prevent water entry into the hull and sustain flotation in the event of drydock failure. All closures shall be accepted by the COTR.
4.1.9 Drydock time for the accomplishment of all above
items is considered within the scope of this item.
5. TESTS/REPORTS/INSPECTIONS
5.1 After docking, the contractor and COTR shall jointly inspect the hull. The contractor shall complete and submit a report of findings and recommendations, including estimates, on a preliminary Docking Report form (Reference 2.2) supplied by the COTR; said report to be submitted within 24 hours after inspection. No remedial work, except as specified in other items, shall be commenced until authorized in writing by the Contracting Officer or designated representative. Items to be
Drydocking of NOAA Ships S0700-1 inspected include:
5.1.1 Hull: Condition as to structural damage, corrosion, welds, rivets, fastenings, caulking or evidence of grounding, collision or excessive strain.
5.1.2 Shaft Bearing: Remove fairwaters and rope guards, etc., as required, and read tailshaft bearing clearances by dial indicator, using feeler gauge to read the rudder bearing clearances.
5.1.3 Miscellaneous Items: Items such as zinc anodes, propellers, rudders, sea chests, scuppers, drains, bilge keels, sonic equipment, etc.
