- Description
- The Olympic Coast National Marine Sanctuary (OCNMS) plans to map seafloor habitat in the Northern half of the Sanctuary using side scan sonar (SSS) to create digital mosaic images of the seafloor for habitat characterization purposes. This scope of work (SOW) addresses two program elements: (1) an OCNMS element for the provision of a vessel, captain and crew and side scan sonar fish(es) and associated equipment and staff for operating in depths of 100 to 400 m, and (2) side scan sonar fish and associated equipment and one technician for operating in depths of <50 m off the RV Tatoosh, a 38 foot vessel owned and operated by OCNMS. The RV Tatoosh is equipped with an A-frame, hydraulic winch, davit and an 1800 watt AC invertor. The side scan sonar survey is being conducted to support seafloor mapping as further described in this solicitation. Contractors can bid on the one or both elements in this package: nearshore and offshore side scan. The costs for each element should be presented as separate cost items. The duration for element (1) is for 5 to 10 continuous days for 24-hr per day operations between 1 July and 30 September 2002. The duration for element (2) is for 5 to 10 days of 12-hr per day operations from 15 to 26 July 2002. The contractor responsibilities are listed below. Project Area: For program element (1) the project concentrates on the area between 124?57'W to 125?20'W and between 48?03N to 48?20N in U.S. waters (Figure 1). For program element (2) the project concentrates on the area between 124?44'W to 124?52'W and between 47?55N to 48?09N (Figure 1). These project areas are approximate and some minor changes may be made by OCNMS during the survey. Program Element (1) Scope of Work Program element (1) will be between 5 and 10 continuous days of operation in the OCNMS. A port day can be added but is not considered as one of the 5 to 10 continuous days. Mobilization and demobilization days, as well as transit time to and from the Sanctuary are in addition to the 5 to 10 continuous days of operation within the Sanctuary. Vessel operations will be conducted 24 hrs/day. The survey shall be completed between 1 July and 30 September 2002. The dates and length of the cruise will be set at the time the contract is awarded. Loading of contractor equipment at location of contractors choice; however, contractor shall plan for OCNMS staging (mobilizing) in Port Angeles, WA or Neah Bay, WA. In Port Angeles this can be arranged by contacting the US Coast Guard and City of Port Angeles for access to the city pier. Demobilization can occur in either Port Angeles or Neah Bay, WA and will be set at the time the contract is awarded. Note: OCNMS does not expect to have much gear to mobilize, mainly staff and computers. Bids packages for Program Element (1) should be based on the 5-day survey plus mobilization, demobilization, and transit time, with a daily rate for each additional survey day up to 10 days. Vessel: The contractor shall supply a vessel, with crew, of sufficient size/tonnage to operate 24 hrs/day, for the length of the cruise, up to 40 nm off the Washington Coast. The minimum vessel length is 80 ft. The vessel must have appropriate deck equipment (winches, metering device, A-frames, davits, etc.) & operators to deploy and operate the side scan and associated equipment. The vessel must also accommodate up to 3 OCNMS personnel with berthing, shower & head. The vessel shall provide meals. The vessel shall be equipped with a differential global positioning system (DGPS). For this element two potential boats follow; however the contractor should not feel obligated to use these vessels. Both have operations ongoing in the Sanctuary; therefore, mobilization and demobilization costs may be saved by using them. Fishing Vessel Northwind, Inc. Velero IV 1441 N. Northlake Blvd. PMB 535 Seattle, WA 98103 6201 15th Ave NW Attn.: Ms. Susan Rubatello Seattle, WA 98107 Phone: (206) 632-1441 Attn: John Hayes Fax: (206) 632-8628 Phone & Fax: (206) 352-7495 Cell Phone: (360) 481-1911 Side Scan Data Acquisition System: The contractor shall provide a SSS system to collect digital SSS imagery for mosaicing. A tow fish such as an Edgetech DF1000, Klien 5000, or equivalent shall be used, maximizing resolution between 200-300m depth but capable of mapping depths of 100-400m depths. The digital side scan sonar data shall be geocoded using the tow fish position. The tow fish geographic position (GP) shall be calculated using the DGPS system and a Sonadyne, Track Point II, or comparable USBL system. Cable out should be recorded on a common time base. Digital SSS Data Format: The contractor shall provide the digital SSS data in a format readable by CARIS HIPS (version 5.2) by Universal Systems LTD, phone (506) 458-8533, however logging to Triton-Isis (XTF) is desirable. Information and specifications on CARIS SIPS and data formats may be obtained from Universal Systems LTD. Positioning shall be NAD83/WGS84 coordinate system. Greenwich Mean Time shall be used for all aspects of data collection. Data shall be delivered on CD media. Operations: 1. Accuracy - The side scan sonar system shall be operated in such a manner that it is capable of detecting and recording vertical differences in the seabed of 15 cm and 20 cm horizontal differences in an across track orientation. 2. Range Scale - The achievable horizontal range scale of a side scan sonar is a function of several parameters. Among these are sonar conditions, seabed composition, range scale in use, side scan sonar system characteristics, and tow fish height. Actual conditions in the survey area will determine the effective range of a particular side scan sonar system. If the effective range scale of the side scan sonar is reduced due to external factors, then the acceptable swath coverage should be reduced accordingly. The SSS shall be primarily operated on the 200-meter range scale but may change at the discretion of the OCNMS or designated representative. 3. Line Spacing - Line survey lines shall be oriented parallel to each other and be spaced at a distance 50% of the effective range scale apart. 4. Survey Speed -The pulse repetition rate (PRR) determines the speed at which the transducer (i.e. the vessel) can move along the track and still maintain the required along track coverage of the bottom. Longer-range scales have slower PRR which require slower vessel speeds. The side scan shall be towed at a speed such that an object 0.5 m3 on the seafloor would be independently ensonified a minimum of three times per pass. The maximum vessel speed for three ensonifications can be calculated as follows: Maximum vessel speed (m/s) = target size (m) x prr/3 (sec-1). 5. Tow fish Height - The side scan tow fish shall be towed at a height above the bottom between 8% and 15% of the range scale in use. For tow fish heights below the 8% of the range scale in use the effective scanning range is defined as 12.5 times the tow fish height, provided adequate echoes have been received. 6. Confidence Checks - Confidence checks of the side scan sonar system shall be conducted at least once daily. These checks should be accomplished at the outer limits (~85%) of the range scale being used. Each sonar channel (i.e., port and starboard channels) shall be checked to verify proper system tuning and operation. Confidence checks can be made on any discrete object, offshore structure, or bottom feature that is convenient to the survey area. Targets can include wrecks, rocks, navigation buoy moorings, distinct trawl scours, or sand ripples. Communications: Because the scientific staff may need to communicate with other research vessels, commercial vessels, & shore based facilities, the Chief Scientist or designee shall have access to use of radio transceivers & other available communication equipment. Mechanical Breakdown: The contractor is responsible for maintaining all contractor provided equipment & vessels in a safe operating condition during the contract performance. If a mechanical breakdown occurs of the vessel or SSS equipment that is >12 hrs, the vessel & SSS equipment shall be considered to be off charter for the purposes of billing. The contractor shall make every reasonable effort to solve any problem causing a vessel and/or SSS equipment to be out of service, & bring it back into service as quickly as possible to continue contract performance. Fuel & Water: The contractor is responsible for providing all fuel needed to perform the contract. Any breaks from contract work to take fuel or water will be considered time off charter, for billing purposes. Program Element (2) Scope of Work: Program element (2) consists of the contractor providing side scan tow fish and associated equipment, cable and navigation system to support conducting side scan sonar operations off the RV Tatoosh. This survey will be 5 to 10 continuous days of operation in the OCNMS. Mobilization and demobilization will occur in Neah Bay, WA. Mobilization and demobilization days are in addition to the 5 to 10 continuous days of operation within the Sanctuary. Vessel operations will be conducted 12 hrs/day. The survey shall be completed between 15 to 26 July 2002. OCNMS will provide lodging in Neah Bay; however, the contractor will include other travel expenses. Bid packages for Program Element (2) should be based on the 5-day survey plus mobilization, demobilization, and transit time, with a daily rate for each additional survey day up to 10 days. Side Scan Data Acquisition System, Digital Data Format and Operations: The SSS requirements follow those as stated under Program Element (1), except that the tow fish shall be primarily operated on the 50-meter range scale (but may change at the discretion of the OCNMS or designated representative), and positioning of the fish may be accomplished using algebraic calculations or similar algorithms taking into account measured cable out, water depth, fish height and cable cantenary. Mechanical Breakdown: The contractor is responsible for maintaining all contractor provided equipment in a safe operating condition during the contract performance. If a mechanical breakdown occurs of the SSS equipment that is >6 hrs, the SSS equipment shall be considered to be off charter for the purposes of billing. The contractor shall make every reasonable effort to solve any problem causing SSS equipment to be out of service, & bring it back into service as quickly as possible to continue contract performance. Items Common to Both Program Elements: Reports & Documentation - The contractor shall record & maintain a record throughout the cruise. Information on daily operations, problems encountered, weather and sea conditions and operational milestones shall be recorded. The contractor shall record digitally the geographic position of the vessel throughout the cruise with positions logged every minute. Geographic positions shall be in NAD83 or WGS84 coordinates & recorded to accuracy equivalent to the 5th decimal place using decimal degrees. A digital track line file in ASCII format shall be provided to OCNMS at the completion of the project. All times shall be recorded in Greenwich Mean Time (GMT). The contractor shall provide a descriptive report of the survey operations. The report shall contain but not be limited to all data necessary to complete office processing of the survey data, environmental conditions encountered that may have a bearing on data quality or accuracy, methods used and circumstances encountered during data acquisition.
