AMENDMENT 0005 3 May 17, 2019

1.0 SCOPE

1.1 This Statement of Work (SOW) defines National Data Buoy Center’s (NDBC) Basic Ordering Agreement vessel qualification requirements for the marine services to conduct maintenance of marine observing systems in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the Pacific Ocean. Network descriptions, physical characteristics and representative examples of the types of buoy systems currently operated by NDBC are contained in Attachment 1. If the vessel is required to support service on any other types of buoy systems, the requirements will not exceed those in this Statement of Work.

1.2 The contractor must furnish the vessel, crew, material, equipment, services, and facilities, as described in this SOW, to permit government field service personnel to perform the buoy maintenance specified in each Task Order Request for Quote (TORFQ). Vessels must be able to lift the buoy onto the deck, secure the mooring to the deck, hold position over the mooring while the buoy is being serviced or exchanged, and deploy the buoy back in the water. The vessel must also be able to retrieve entire moorings that are freed from their anchors by acoustic releases or pressure- activated line cutters.

1.3 The Global Class vessel is primarily intended to support maintenance of the Deep-ocean Assessment and Reporting of Tsunamis (DART) network; Weather and Ocean Platform (WxOP) buoys in the Caribbean Sea, Bay of Campeche, and South Atlantic Ocean; and selected Tropical Atmosphere- Ocean (TAO) buoys. When operating near a drifting buoy, the vessel may be called upon to retrieve and bring aboard any of the three types of buoys described in Attachment 1, along with its mooring remnants.

1.4 The vessel must be able to transport the Government Furnished Equipment (GFE) specified in this SOW from one United States port to another United States port (including San Juan, Puerto Rico and Apra, Guam) or to or from the following non-U.S. ports:

Yokohama Japan Caldera Costa Rica Christobal Panama Auckland New Zealand Papeete Tahiti Apia Samoa Kwajalein Marshall Islands Manzanillo Mexico Arica Chile

1.5 The Government will verify each vessel’s compliance with the requirements of this Statement of Work through documentation review and physical inspections. Each proposed vessel must meet these requirements to be awarded a Basic Ordering Agreement (BOA). The requirements in this SOW, which generally include inherent vessel characteristics, are a subset of the requirements that the contractor must meet to be awarded a contract. The remainder of the requirements (crew qualifications, certifications, contractor services, etc.)

must be satisfied in order to be awarded a contract for the services specified in a Task Order RFQ (TORFQ).

1.6 The Verifications section of this Statement of Work defines which requirements must be met prior to award of a Basic Ordering Agreement in the Global class.

DESCRIPTION OF NDBC BUOYS AND BUOY NETWORKS

Weather and Ocean Platform (WxOP) Network. NDBC currently has 110 Weather and Ocean moored buoys. The U.S. Coast Guard buoy tenders provide vessel support for servicing Weather Buoys within or near the boundaries of the U.S. Exclusive Economic Zone. Weather buoys are typically serviced every two years, and exchanged (refurbished) every three years.

Their moorings are typically inspected every two years and replaced every four to five years. NDBC charters a Global Class Vessel each Spring to maintain the remaining 14 Weather Buoys located in the Bay of Campeche, Caribbean Sea, and South Atlantic. NDBC may charter a Global Class, Global Science Class, or Regional Class vessel to perform scheduled or discrepancy service on any WxOP buoy at any time, depending on available funding, urgency of the repair, and availability of a U.S.

Coast Guard vessel. The following figure shows the geographic distribution of the WxOP network:

A complete and current listing of NDBC WxOP buoys can be found at:

http://www.ndbc.noaa.gov/wstat.shtml

WxOP Weights and Dimensions. While NDBC still operates and maintains a few large 10- meter and 12-meter discus and 6-meter NOMAD buoys, Global, Global Science and Regional Class vessels will only work with 3-meter diameter discus buoys. NDBC may use Global and Regional Class Vessels to maintain other Weather buoy configurations in the future, but these configurations will not exceed the weight or size of a 3-meter discus buoy. The following figure depicts the configuration of a 3-meter discus buoy.

AMENDMENT 0005 15 May 17, 2019 http://www.ndbc.noaa.gov/wstat.shtml

WxOP Moorings. The 3-meter discus buoy uses three basic types of moorings, depending on the depth, currents, and bottom type: All-Chain, Semi-Taut, and Low-Load Compliant. All- Chain and Semi-Taut moorings are generally fully retrievable. They are brought up onto the deck of the servicing vessel for inspection every two years. The Low-Load Compliant mooring is not subject to the abrasive forces that the other two types experience and is generally not retrieved, but is inspected down to the top of the uppermost nylon section every two years. The following mooring diagrams are representative of these three mooring types:

Tropical Atmosphere and Ocean (TAO) System. NDBC is responsible for the production, integration, recovery, repair, and deployment of fifty-five Tropical Atmosphere Ocean (TAO) buoys and moorings and four subsurface Acoustic Doppler Current Profilers (ADCP) along the equatorial Pacific Ocean region extending from 9° N Latitude to 8° S Latitude and 95° W Longitude to 165° E Longitude. The buoys are configured for ocean climate studies of the El Niño/Southern Oscillation.

The standard configuration TAO buoy consists of one air temperature/relative humidity sensor, one anemometer, one sea surface conductivity/temperature sensor, eight ocean temperature sensors, and two ocean temperature/pressure sensors. The TAO flux configuration adds one barometer, one shortwave radiation sensor, one rain gauge, up to five sub-surface current meters, and up to seven additional sub-surface ocean temperature sensors or ocean conductivity/temperature sensors. The surface buoy consists of a fiberglass toroid, approximately 2.6 meters in diameter, an aluminum tower, and a stainless steel bridle. The assembled surface buoys (with tower, bridle, and instruments) and weighs approximately 1,600 pounds. The overall height from the top of the wind sensor to the bottom of the bridle is 16 feet.

The photo below shows an assembled TAO surface buoy ready for deployment:

TAO Service Strategy.

Acquisition of data from the TAO array depends primarily on regular maintenance. Each TAO station must undergo a full recovery and deployment (R/D) annually. An R/D consists of recovering the buoy and entire mooring above the anchor (inspecting the nylon line as it is brought aboard); replacement of buoy, sensors, and damaged nylon line sections; and deployment of the new system on a new anchor.

The distance of the array from shore and the distances between individual stations and between longitudinal lines dictate line-by-line cruise planning. A typical TAO cruise will consist of servicing seven buoys along one longitudinal line (from 8°N to 8°S) then servicing a portion of another longitudinal line, depending on the condition of the recovered buoys and moorings and how much equipment the vessel can carry.

When the vessel is equipped with a Conductivity, Temperature, and Depth (CTD) system and survey technician, verifying performance of each newly deployed system is done using a Sea- Bird SBE9-plus sensor and rosette with Niskin bottles. CTD casts near each TAO station are to 3,000 meters depth.

Schedule permitting, the vessel may also conduct 1,000 meter CTD casts at each whole degree between 8°N to 8°S, and additional 1000 meter CTD casts at each half degree between 3°N and 3°S

TAO Moorings.

The upper 700 meters of a TAO mooring consists of a non-rotating 3/8 inch diameter wire rope jacketed to1/2 inch (NILSPIN). Below that is a swivel, short length of chain, 11/16 inch diameter nylon rope (length determined by water depth), an acoustic release, and anchor system. To ensure that the upper section of the mooring is nearly vertical, moorings in water depths of greater than 1800 meters have a nominal scope of 0.985 (ratio of mooring length to water depth). The scope can be increased to 1.35 to improve mooring reliability in areas of high currents. A 4,666 pound single stack anchor is normally used, except on stations at the equator and 2° North Latitude, where a 6,200 pound double stack anchors is used. The ADCP mooring configuration consists of one float containing an ADCP that is anchored approximately 270 meters below the sea surface. The anchor is a 1,700 pound single stack. The following figures show typical TAO and ADCP Moorings:

Deep-ocean Assessment and Reporting of Tsunamis (DART®) System

The DART® system consists of an anchored seafloor bottom pressure recorder (BPR) and a companion moored surface buoy for real-time communications with the U.S. Tsunami Warning Centers. An acoustic link transmits data from the BPR on the seafloor to the surface buoy. The following figure depicts the operation of the DART® II System, which was became operational in 2005.

The 39 stations in the DART network are shown in the figure below:

AMENDMENT 0005 26 May 17, 2019

DART Weights and Dimensions. The DART surface buoy is a fiberglass hull with a stainless steel bridle, 2.6 meters in diameter and 12 feet tall, including bridle. The assembled buoy weighs approximately 3,000 pounds. The following figure shows the DART surface buoy

AMENDMENT 0005 27 May 17, 2019

The DART Bottom Pressure Recorder (BPR) rests on the sea floor under the buoy.

The following figure shows the BPR configuration. The lower table is the anchor. During recovery, the upper table with instruments is released from the anchor and is lifted up by a string of floats.

The BPR assembly is approximately 48 inches x 39 inches x 48 inches tall. With anchor, it weighs approximately 1,200 pounds. Some BPR’s are equipped with surface activated strobe lights for recovery at night.

DART Moorings. A DART mooring consists of an upper stainless steel chain assembly, swivel, 3/4 inch diameter fishbite-resistant Vectran line, 3/4 inch nylon rope, and a 6,000 pound double stack anchor. To ensure that buoy stays over the BPR, within the communications cone of the acoustic transducer, the mooring must be nearly vertical. DART moorings have a nominal scope of 0.97 (ratio of mooring length to water depth). The figure on the following page shows a typical DART mooring.
