PERFORMANCE WORK STATEMENT (ATTACHMENT E)

Surveillance Towed Array Sensor System-Expeditionary (SURTASS-E) Support Vessel (long-term)

1.1 Mission: The Military Sealift Command (MSC) requests one US flagged or foreign flagged (to be reflagged US) vessel required to tow an acoustic array in support of U.S. Navy Operations. This is a mission essential requirement which will require a mission essential contractor services plan (MECSP, Part X(z)).

1.2 Area of Operation: The vessel must be capable of worldwide operations. This includes support in all ocean basins of the world from the Artic to the Antarctic during all periods of time, when navigable and ice breaking certification is not required. The vessel operator must also be capable of sustaining the vessel worldwide.

1.3 Operating Scenario: The vessel will tow a passive acoustic monitoring system, between 4-6 knots, 24hours/day for up to a 60-day event. The ship will need to be able to tow on a directed heading within 5 degrees for extended periods at slow speed. Because of the type of acoustic system employed, the ability of the vessel to maintain heading stability is critical.

3 Vessel Characteristics - Mission System Support

a. The vessel shall have a clear weldable deck area of a minimum of 5,008 ft2 (465.3 m2) for installation of the mission system vans and winch plus an additional approximately 710 ft2 (65.96 m2) for the installation of a walkway from the ship’s main deckhouse to the mission system vans installed on deck. Area shall be clear of any emergency hatches or scuttle locations. Access to any sounding tube or other locations requiring routine service shall not interfere with the mission system placement. The ship’s deck area must accommodate the installation and welding of the mission system as identified in Diagram 1d-1f and installation of three over-boarding poles shown in Diagram 5.

The deck layout identified in Diagram 1a-1c represents the nominal deck configuration as currently employed. Adjustments to the location of the major components, shown in Diagram 1a-1f, may be allowed to support vessel underlying deck structural configuration and allowable deck loading. Diagram 2 shows the government furnished walkway and a notional configuration. The walkway is nominally 4 ft. (1.22m) wide and runs along the centerline of the vessel. The exact length of the walkway is determined by the distance from the ship’s deckhouse to the first set of mission vans.

The installed government mission equipment can be considered as three regions that may have their physical location modified from the nominal location within the constraints listed below. The walkway shall be flush with Handling System Group (HSG) Platforms. Minor adjustments to the location of major components may be allowed to support vessel structural loading. If the contractor’s deck configuration, Mandatory Requirements as proposed under the RFP, deviates from Diagram 1a through Diagram 4 in terms of location, at a minimum the deck configuration must adhere to the following restrictions:

1. Over-boarding chute and handling platform; The chute and handling platform shall be located immediately adjacent to the transom of the vessel.

No deviation in the location is authorized. This chute handling platform will be installed in the deck footprint identified in paragraph 3.d. and 3.g.

2. The winch and On Board Repair Parts (OBRP) Module Stowage Reels, and supporting integration framing foundations; The winch and OBRP Module Stowage Reels vans positioning can vary from being located immediately forward of the handling platform, to a location where the aft most section of the winch frame is no greater than twelve (12) feet (3.66 m).forward of the over-boarding platform. The relative position, port and starboard, of the winch and handling platform cannot be changed. The winch and van position may only be adjusted forward and aft.

3. Portable Accommodation Module (PAM) and supporting integration framing foundations (forward 6 or 9 vans).; PAMs for the mission system shall be installed in a two or three row configuration as illustrated by SURTASS-E Van Configuration Drawing (SES-D-00169) illustrated in Diagrams 1b through 1f. The installation of 6 or 9 units is at the discretion of the government. These vans represent the primary manned vans. The PAM structure and supports may be located immediately forward of, and adjacent to, the OBRP modules van or moved forward on the deck not to exceed 50 feet from the axial center of the winch. The PAM section is not required to be aligned linearly with the areas in section 3.a.1 or 3.a.2. However, the section orientation cannot be changed from that shown where the long axis of the PAM units is forward/aft relative to the ship’s centerline. The secondary intent is to allow the PAM section to be located further forward to minimize the amount of open deck that personnel must transit during heavy seas.

NOTE: ABS certification for deck configuration must meet government requirement to complete the full installation and certification of the system within 7 days of receipt of materials, exception of unforeseen circumstances beyond the operator’s control. Current government ISO mounting hardware is approved by ABS for single deck configuration.

Government will require the contractor to clearly demonstrate, with data, how any alternative configuration can be certified to meet government need.

Contractor is responsible for any cost associated with installation of Government Equipment to include, but not limited, to welders, gas free engineering, class surveyors, etc. Diagram 3 provides a nominal deck welding layout and is not a directive for welding installation and cannot be used to form the basis for a request for equitable adjustment. It is the responsibility of the contractor to safely install the GFE. Upon delivery and when all GFE is provided, the Contractor shall ensure that all GFE required is welded to the deck, approved by Class, and is ready in all respects to conduct missions within four days of receipt of GFE.

b. When the government equipment is placed on deck, the following additional conditions must be satisfied:

1. In the deck area adjacent to, and aft of the mission system VAN location, there can be no height obstruction greater than 15 feet (4.572 m).

2. Additionally, the only allowable obstruction can be within a zone +/- 45 degrees, as measure from the centerline of the forward most center VAN, when installed on the deck, as illustrated in Diagram 1a.

3. The allowable obstruction restriction of paragraph 3.b.1. and 3.b.2. applies to the forward most row of vans in the 7-van configuration and from the center row of vans in the 10-van configuration.

4. All deck area must be co-located on one level.

Note: Current government ISO mounting hardware is approved by ABS for single

(3.05-9.14 m) vertical poles as depicted in Diagram 5: including one supporting an acoustic speed sensor and a second pole supporting a fathometer transducer. All three will be deployed over the side during towing operations. Each over boarding pole will be supported by two welded platforms.

n. The vessel operator shall adhere to all regulatory requirements for the safe installation and removal of the GFE Acoustic Doppler Current Profiler (ADCP) system, so as to ensure its proper operation. This system shall be installed on one of the swing arms identified in paragraph m. The final swing arm location should avoid interference with vessel fixtures (i.e. fuel vent) and be close enough to the van pad to run a 100-foot data power cable between the sensor and the operator van. Sufficient room aft should also be planned to mount the additional beam for the guide wire aft.

No more than 5 narrowband sources greater than 15dB will be considered acceptable. If at any time, the contractor is found to not meet the noise requirements, the Contractor must clearly demonstrate how the noise source can be mitigated. The determination of whether or not a source is or can be adequately mitigated is at the sole discretion of the government.

NOTE: The government reserves the right to verify that the vessel meets the radiated noise requirement (4.a) upon delivery.

The Contractor shall maintain certification throughout the duration of the contract period. The Government retains the right to reinspect and/or run the test on a government facility. Costs associated with this testing will be the responsibility of the Government. If at any time it is determined the vessel does not meet the PWS requirements, the cost to regain compliance is the responsibility of the Contractor.

d. The vessel operator / contractor shall have the hull cleaned on an annual basis. All annual hull cleanings shall be scheduled in a manner that does not interfere with missions.
