PERFORMANCE WORK STATEMENT (PWS)

FOR

HYDROGRAPHIC WINCH SPOOL REFURBISHMENT AND CABLE WINDING

February 8, 2021

PART 1

GENERAL INFORMATION

The 1500lbs, 32” wide by 48” high, empty drums made of steel with grooved plates and painted with marine epoxy paint. Approximately 10,000 meters of ¼” steel communication cable wound onto the drums with 2000lbs of tension. This results in a new spool weighing roughly 6,000lbs. When an installed spool on a ship degrades, it is sent back to NAVO for refurbishment, removal of remaining communication cable, and rewinding of new cable under proper tension.

NAVO does not have the proper equipment to accomplish refurbishing and winding new cable onto the CTD spools. This contract is to employ a vendor who is capable of receiving old drums, removing any remaining cable and disposing of it, refurbishing the drum to NAVO paint specifications, and winding new communication cable onto the drum per NAVO specifications.

1.3.4 The contractor will test NAVO provided communication cable for proper function per NAVO spec and document result. This procedure is performed prior to winding cable onto spool and after winding the cable onto the spool.

PART 2

DEFINITIONS & ACRONYMS

2.1 Contracting Officer’s Representative (COR): A representative from the requiring activity assigned by the Contracting Officer to perform surveillance and to act as liaison to the contractor

2.2 CTD. Conductivity, Temperature, Depth.

2.3 NAVO: Naval Oceanographic Office

2.4 Spool or Drum: Spool or Drum used interchangeably to refer to the piece of equipment that the holds cable.

PART 3

SPECIFIC TASKS

3.1 Remove old cable:

3.1.1 Per contractor’s procedure, remove old cable from the spool and it may be disposed of in any way the contractor decides is most economically feasible and to the contractor’s benefit. NAVO does not want the old cable returned.

3.2 Refurbish drum/spool:

3.2.1 Per contractor’s procedure, all old paint and rust is removed prior to repainting of the spool. Each spool has two grooved plates bolted to them.

3.2.2 The grooved plates are removed, resurfaced front and back, and bolted back on to the drum. CRITICAL STEP, the grooved plates must be bolted back on with the exact same orientation as they were removed. Failure to bolt plates on with correct orientation will result in improper cable lay during winding.

3.2.3 Repaint the spool using Amercoat 240 anti-corrosive two-part epoxy, or equivalent marine grade epoxy if Amercoat 240 is unavailable with NAVO approval. One base coat white and one top coat grey, sprayed, rolled, or brushed on.

3.4 Wind new cable onto the empty spool:

3.4.1 Per contractor’s procedure, approximately 10,000 meters of NAVO provided communication cable is wound on with 2000 lbs of tension.

3.4.2 CRITICAL: in order to attach communication cable to ship’s slip ring, at least 3 meters of cable should be pulled through the grooved plates and attached to bolted connection on spool.

3.4.2 At the completion of winding on new cable, a clamping device used to secure the end of the cable to itself in order to keep the cable from unraveling during transportation and storage.

3.5 Test cable for Function:

3.5.1 Per NAVO specification, communication cable shall be tested prior to cable winding and after cable winding. A record of these tests shall be provided to the NAVO representative.

3.5.2 NAVO understands that the testing specification may contain outdated equipment or procedures. With the approval of the NAVO representative, the contractor may perform the equivalent tests with their preferred equipment.

5.2 Spool/Drum for refurbishment

5.2.1 1500lbs, 32” wide by 48” high, empty drums are made of steel with grooved LeBus plates and painted with marine epoxy paint. These drums may or may not have old communication cable wound onto them. If they have cable wound onto them, they may weigh up to 6000lbs.

5.3 Shipping pallet

5.3.1 Where feasible, NAVO will ship the old spools on an appropriate, specifically built for the CTD spools, pallet. NAVO expects contractor to return refurbished spools on this pallet or equivalent.

5.4 Communication cable

5.4.1 NAVO will provide contractor with 10000 meters of communication cable. This cable is used to wind onto the refurbished spool.

5.4.2 NAVO will test and document the cable function prior to shipping and provide test document to contractor rep.

5.4.3 Contractor is responsible for testing cable prior and after winding. Contractor is responsible for securing new cable or rectifying the problem if final test is unacceptable after winding.
