SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

AMENDMENT 9

RFI Group 9 177 Spec Section C655 requires "All hydraulic piping, fittings and valves shall be of stainless steel." Suggests amending to stainless where exposed to weather.

Some control valves are not available in stainless and only requiring corrosion resistant valves in the weather would reduce system cost.

a. USACE Response: Please see revised Contract Paragraph C655. The Contractor shall ensure that with this revision that there are no dissimilar metals per the requirements in Contract Paragraph C404.

178 Spec requires DR-68 for reduced freeboard which requires an emergency dump for the bottom doors. Section C514 does not mention an emergency dump (open) but it does have an emergency close. Is it possible the "emergency closing" should be "emergency opening"? OR do we need to account for both?

a. USACE Response: Please see revised Contract Paragraph C514 for clarification.

179 Section C655 requires "The main pump(s) shall be remotely adjustable, varying between idle and maximum. Pressure control in the hydraulic system shall either be accomplished hydraulically or electronically." Does this imply VFD controlled pumps? Hydraulic pumps are typically on/off and the fluid is controlled via proportional valves or pressure reducing valves. Pump speed control is not advised.

a. USACE Response: Contract Paragraph C655 allows for either variable displacement hydraulic pumps or fixed displacement pumps driven by variable speed electric motors. The intent is to save energy and reduce fluid heating by allowing the pump output to vary to match the hydraulic system flow and pressure requirements for the various modes of operation. Please see revised Contract Paragraph C655 for clarified requirement.

180 Section C630 requires "flow meters on the suction and return lines from each engine, such that the fuel consumption of each engine can be monitored. This information shall be supplied to both the dredge automation system (see Contract Paragraph C524) and the IMACS (see Contract Paragraph C780)."

Engine manufacturers state flow meters on supply/return fuel lines can starve the engine at high power. The engine controls monitor the rate of fuel consumption from which consumption can be calculated and reported by the IMACS and dredge automation.

a. If the "fuel consumption" and "rate of fuel consumption" values can be determined by the engine controls, can the flow meters be removed?

b. USACE Response: The Government will not remove this requirement as it is required for the DQM system interface per Contract Paragraph C524.

181 Section C630 requires "fuel oil coolers in the return lines to the day tanks, in accordance with the prescribed requirements of the engine manufacturers.

"The engines we'll propose have on-engine FO coolers on the supply lines and do not require coolers on the return lines. Do we have to have them on the return lines?

a. USACE Response: The Government will not remove this requirement.

182 Please consider delivery and acceptance FOB Origin after sea trials or dredging trials. Proprietary Statement to USACE: Vessel delivery included in the contract adds risk to program considering USACE cost target. This also penalizes offerors based on location.

a. USACE Response: The Government will not remove this requirement.

183 Recent amendment responses to questions concerning the bow thruster continue to leave some question with regards the requirements on bow thruster sizing. There is a large swing in thruster sizing depending on the interpretation. Please confirm the required operational profile for proper bow thruster sizing, including specifying exactly which conditions occur simultaneously. Worst case scenario for DP would then be 3.5 kts cross current with 20 kts cross wind. Is this correct?

a. USACE Response: Please see response and revision from RFI 175.

184 C121 Bow Thruster. Related to the previous question it may be interpreted by the latest Amendment #7 answer to question 117 that the USACE is permitting the use of the aft thrusters to turn the vessel and the bow thruster(s) are only to be used in a DP capacity when dredging. Please confirm.

a. USACE Response: Please see response and revision from RFI 175.

185 Amendment #2 provided revised contract language by deleting the words “deep water and’, yet in two of the following three conditions which are defined they are described as being in deep water “Full Load Dredging Transit Condition in deep water…”. In C121 in the first sentence under REQUIREMENTS it states “The Contractor shall conduct the validations listed in Sub-paragraph SPECIAL FEATURES for each of the three six conditions listed above in Contract Paragraph C120.” The “three” was scratched out and replaced with “six” yet there are only 3 conditions defined in Contract paragraph C120. The cost of conducting the requested complete Phase II CFD analysis is extremely high. The Government must provide concise wording in order to accurately price this requirement.

a. USACE Response: Three conditions is correct per the revised Contract Paragraphs C120 and C121. “Six” was crossed out in the revision not “three.”

186 ..Please confirm that the intended launch must be engineered for 25 knot speed in 6-foot significant wave height. Sources for these craft indicate this requirement will cause an elevated cost to produce a custom structural design. Is it possible to modify the requirement to “Design shall be adequate for 25 knot speed or 6-foot significant wave height”?

a. USACE Response: Please see revised Contract Paragraph C446 with revised requirements.

187 Concerning the calculations required in Phase II for the dredge wear parts, what is the expected lifecycle to replacement time period in years for these dredge piping system components?

a. USACE Response: Per Contract Paragraph C502, “the calculation shall demonstrate the estimated lifetime for the dredge wear parts based on the materials chosen for the dredge parts and the type of dredge materials as described in Contract Paragraph C002.”

188 Proprietary Question - Understanding the need for the USACE to receive sufficient evidence of both labor and material progress to support requests for progress payments, as well as monitor contractor performance, would the USACE consider alternate material cost statusing approaches other than that described in the EVMS section. For past USACE programs in which Contractor has supported, we have submitted copies of all purchase orders, projected budgets, material order schedules, and resource loaded progress payment submittals that have status for both labor and material.

a. We believe our current labor progressing system meets the EVMS requirements as stated in the RFP, however, for materials, we foresee issues with compliance to a conventional EVMS type material statusing system. What is currently specified is much more onerous on the shipyard and does not provide sufficient value for cost and effort required to develop the data. Contractor believes we can provide material statusing of sufficient evidence through other project data that will be fully available to the USACE, similar to what has been utilized on previous programs.

b. Question – Will the USACE accept material progress/status reporting similar to what has been done on conventional USACE construction programs, in lieu of requirements described in the EVMS H06 Construction Plan section of solicitation.

c. USACE Response: EVMS reporting is required for this contract as described in Contract Paragraph H06.

189 Background Discussion - The modified section on page 237 of 240 within the Solicitation Paragraph C655 – Hydraulic Systems, retained the requirement for two independent hydraulic power units (HPU’s). Although, clarifying the requirement for tank locations to be either on the skid or integral to the ship’s structure, a requirement for two (2), independent reservoirs serving the two (2), independent HPU’s can still be inferred. Requiring two (2), independent reservoirs is a potential for a severe safety incident. If appropriate valves are not moved to their respective locations, one system would drain its reservoir and return the hydraulic fluid to the other system’s reservoir. This can result in a potential for overflow and an environmental hazard, as well as introducing air into the entire system as a result of too low hydraulic oil capacity in the original system’s reservoir, rendering the system inoperable.

a. Additional background discussion - A simple and inexpensive solution would be to include three-way valves, serving the two (2) systems and drawing from and returning to a single reservoir. An additional benefit to having a single reservoir is freed-up space that can be used to increase the size of the single reservoir, which in turn will increase the system’s capacity to absorb thermal energy, thereby potentially reducing the need for an HPU box cooler as required in Solicitation Paragraph C640 – Engine Cooling System. Potentially removing the box coolers will lead to additional cost savings.

b. Question 1- Are the independent, primary/standby HPU’s required to have independent reservoirs or can the two (2) HPU’s draw from and return to a single reservoir?

c. Question 2 - If it can be calculated in 849-C655-04 HYDRAULIC SYSTEM CALCULATIONS that a box cooler is no longer needed for proper system operation using a larger, single hydraulic reservoir and given the environmental constraints listed in Solicitation Paragraph C002 – Vessel Operation and Primary Requirements, could the use of a box cooler serving the centralized HPU system be listed as optional?

d. USACE Response: The revised Contract Paragraph C655 requires two

(2) pumps each with its own reservoir. There shall not be a connection between the two reservoirs which eliminates the risk mentioned in this RFI and provides the required redundancy for the system. Tanks may be arranged such that there is a single partition within a single tank making the tanks side by side.

190 Does the hopper require a coating system? The hopper area is not covered in document 849-B406-01 - MDC Standard Paint Schedule - Rev 0. Please advise coating system requested inside of hopper.

a. USACE Response: Hopper does not require a coating system. Please see revised Contract Paragraph C335.

191 Based on response to RFI #6 in Amendment 0001, please clarify design standards to be used for ““GLOBAL FEA REPORT 849-C399-03 - Description of the FEA results and validation of adequacy of the structure against the acceptance criteria. The output shall include: Fatigue and Buckling assessment”.

Can the USACE provide criteria for fatigue assessment.”

a. USACE Response: Requirements for the Global FEA Report are included in Contract Paragraph C399. Fatigue and Buckling assessment shall be conducted in accordance with the ABS Guide of Spectral-Based Fatigue Analysis for Vessels and the ABS Guide for Buckling and Ultimate Strength Assessment for Offshore Structures, as stated in the original Solicitation.

192 Section C405 CATHODIC PROTECTION requires "Internal tanks and piping systems intended for sea seawater shall be protected by a cathodic protection system, with a protective duration of at least 5 years.". Please clarify if the dredge piping system, jet water piping system, and flushing systems require ICCP protection.

a. USACE Response: Dredge system piping does not need to include cathodic protection. Please see revised Contract Paragraph C405.

193 Forward looking sonar (IFLS) system integration:

a. Is it the intention of the specification that the IFLS be provided to enable the collection and review of a dredge area survey without the need for a separate survey vessel as is typical within the dredging industry ?

b. Is it the intention of the specification that the proposed dredge be provided with an inertial measurement unit (IMU)?

c. Is an IFLS system display required at the dredge control system console?

d. What is the intention of the line “soil property variations shall be used to govern vessel speed variations and automatic dredge pump, jet pump and visor control settings” (C498, page 153 of solicitation). Is the data from the required dredge slurry velocity and non-nuclear density meters considered sufficient as a method for monitoring “soil property variations”?

e. What is the intention of the line “The multibeam forward looking sonar interface with navigation sensors shall provide an integrated forward-looking sonar system (IFLS) enabling dredging operation to be more precise, allowing for better tolerances to be followed which in turn evolve into an automatic dredging planner. This system shall be integrated with the dredge automation system (see Contract Paragraph C524).”

i. Is the intention that “automatic dredging planner” be a manual crew function whereas the crew utilizes the “past track” / local history map data from the IFLS to better plan the dredge tracks manually inputted into the DP/DT system?

f. Can the intention of the dynamic positioning / dynamic tracking paragraph “The dredging automation system shall interface with the IFLS system (see Contract Paragraph C498) and the DP/DT system (see Contract Paragraph C608) such that the vessel speed, dredge pump speed, jetting pump speed, draghead position, and draghead visor settings can be adjusted for a particular track based on the data coming from the IFLS system.” (Page 188) be further defined?

g. Is it the intention that these adjustments will be determined by the dredge operators and manually inputted into their respective systems?

h. Can the required integrations between the C524 dredge automation system, C498 IFLS system, and C608 DP/DT system be further defined?

Is it the intention of the line “The dredging automation system shall be integrated with the IFLS system (see Contract Paragraph 498) and the DP/DT system (see Contract Paragraph C608) to ensure a fully automated and efficient dredging operation.” Intended to mean the following:

i. The C524 dredge automation system provides the following data to the DP/DT system:

1. Draghead position (x, y, z)

2. Draghead differential pressure

3. Draghead suction vacuum

4. Draghead pulling force

5. Slurry flow velocity

6. Slurry density

ii. The IFLS system past track bottom mapping data be viewable within the DP/DT or ECDIS system

iii. If the intention is to integrate real time data from the IFLS into the dredge automation system to actively control any dredge system actions (raise / lower drag arms, adjust pump speed, etc.) can the required integrations be further defined?

iv. Can the required C524 integrations with the C765 communications system (page 182) be defined?

i. USACE Response: IFLS is not intended to replace survey vessel in dredging but shall assist during dredging operations. Inertial measurement unit is not required for this vessel. Display shall be located at the dredge operator’s station. Data from the required dredge slurry velocity and non-nuclear density meters is considered sufficient for this requirement.

Please see revised Contract Paragraphs C498 and C524.

194 Swell compensation system:

a. Is the intention of the line “Swell compensation compensator: measuring system in cylinder rod, position sensor” on page 182 intended to require a linear displacement transducer (i.e. Temposonics) built into the swell compensator cylinder with an additional external sensor on the swell compensator system, or can both measurements be accomplished with the internal swell compensator cylinder linear displacement sensor?

b. USACE Response: Swell compensator shall adhere with requirements of Contract Paragraph C522 and shall provide information to the dredging automation system on its linear displacement. Transducers or other sensors provided shall be sufficient to satisfy these requirements.

195 Dredge control automation:

a. There is a specification for automatic control of the dragarm winches during trailing (page 183). Can the intention of this requirement be further defined? What are the intended operator inputs to this function?

b. Is it the intention of the specification (page 183) “Optimal production:

combining sailing time and loading time the optimal production is calculated and will show the best time to stop loading.” that the dredge control operator be required to input sailing time and loading time, or is it intended that the dredge control system automatically determine the information as the digging cycle progresses?

c. USACE Response: Operator inputs will be to set dredging depth, and GPS location of the disposal site and dredging site, automatic control of dragarm winches shall be in accordance with Contract Paragraphs C002.jj Dredging System and C524 as stated. Optimal production automation shall inform operators when the dredge should stop loading due to efficiency of operation. Please see revised Contract Paragraph C524.

196 Can the USACE provide NAVSEA T9633-AT-DSP-010, Ship’s Cathodic Protection Design Calculations, Design Requirements Manual as GFI or provide clarification on how it can be obtained as we are unable to locate this reference on public facing sites?

a. USACE Response: Please see revised Contract Paragraph C003 and C405 for removal of NAVSEA requirement due to the difficulty for Government Contractors to obtain NAVSEA T9633-AT-DSP-010.

197 Has the USACE made any decisions regarding the request to consider adding FAR 52.216-4 Economic Price Adjustment-Labor and Material to the solicitation to reduce project risk for both the Offerors and the Government? As Bidders are currently assembling pricing information from their suppliers, not having this FAR Clause on the Contract will have significant impact on costs due to suppliers needing to incorporate risk into their escalation calculations.

a. USACE Response: Please see updated Contract Sections L and M and EPA clause. Due to this update the RFI period has been extended to November 25, 2022.

198 The offeror is still unable to locate Attachment A even though it was indicated it would be provided in prior clarifications and responses. Can the USACE please confirm where Attachment A is located?

a. USACE Response: Attachment has been added after issues with SAM system have been corrected.

199 The stipend value described in Section M states in Item 6 "Maximum stipend pool is $3 Million to allow for up to 3 potential $1,000,000.00 stipends. In the unlikely event more than 4 acceptable proposals are received (1-Contract Awardee, 3-Acceptable Proposals), each eligible offeror shall receive an equal per capita share of the stipend pool ($3 Million)."

a. Question 1 - Since the proposal timeline has shifted for 2 additional months can the USACE increase the stipend amount to offerors.

b. Question 2 - If the awarded shipyard does not receive a stipend, this makes bidders consider including the cost of this effort into the proposals, thus increasing cost to USACE. Please consider adjusting stipend to also include the contract awardee.

c. Question 3 - In the event less than 3 Acceptable Proposals are received (1-Contract Awardee, 1 or 2-Acceptable Proposals), would the government approve splitting of the full $3m stipend pool between the acceptable proposals received.

d. USACE Response: The Government does not intend to change the application of the stipend.

C335 HOPPER STRUCTURE

GENERAL DESCRIPTION

The capacity of the hopper shall be in accordance with the requirements specified in Contract Paragraph C002.

REQUIREMENTS

The hopper geometry shall promote optimal settling and dumping of the dredged material.

The hopper capacity to the maximum hopper overflow level shall be 6,000 Cubic Yards. The API certified hopper capacity tables (Sect. C604) shall be utilized to set the maximum travel on the hopper overflow at height corresponding to 6,000 Cubic Yard capacity.

The hopper shall be open at the top with coamings all around and with 5-foot (1.5m) high splash screens as necessary to prevent dredged material to splash onto deck during hopper loading, in particular around distribution system points over the full length. The splash screens are not to be considered for strength of the hull midship section. At the ends of the hopper the splash screens shall be of increased height to prevent splashing and spilling during loading as the ship pitches.

The hopper plating shall be inclined towards the bottom doors to promote discharge of the dredged material. As much as possible, the hopper shall be free from obstacles that may disturb the longitudinal flow of the dredged material.

The hopper shall be designed for multiple methods of emptying dredged material. The hopper shall be capable of discharging dredged material through hydraulically operated bottom doors (see Contract Paragraph C514). Alternatively, the hopper can be discharged via the HOPPER COLLECTION SYSTEM (See Contract Paragraph C520). If the HOPPER COLLECTION SYSTEM includes a self-emptying channel as an integral part of the hopper structure, the global strengths properties of the Midship Section (See Contract Paragraph C300) shall be assessed both including and excluding the contribution of the material of the self-emptying channel.

The Contractor is to develop drawing 849-C335-01 HOPPER STRUCTURE and submit to the COR and ABS for approval.

SPECIFIC REQUIREMENTS

The Contractor shall specify the required wear allowances for the hopper structure. Wear allowance shall be based on the estimated lifetime, material chosen, and the type of dredge materials as described in Contract Paragraph C002. The hopper plating wear allowance calculations shall be included in the Lifetime Calculation as specified in Contract Paragraph C502. The Contractor shall include additional wear allowances if they do not include a coating system for the hopper.

Due care shall be taken to provide structural continuity at the forward and aft ends of the hopper structure to cope with the change in vessel cross section. Adequate structural transitions are to be provided for introduction of global hull loads into the hopper structure and vice versa. The hopper structure and its integration into the hull structure shall be part of the global FEA model Top and bottom openings in the hopper structure shall be fitted with corner reinforcements if and as necessary.

If a self‐emptying channel is selected, additional wear resistance shall be provided over the complete surface in contact with the dredged material, either by increased wear allowance on the structural plating or by lining with wear resistant cladding plate of increased hardness.

A catwalk shall be arranged above the hopper to handle the locking mechanism of the bottom doors. Platforms for safe access to gantries and walkways to the dredge valves above the hopper shall be installed. Platforms and catwalks shall be in accordance with the requirements of

Contract Paragraph C425. This catwalk may interface with those required by Contract Paragraph C512.

C498 FORWARD LOOKING SONAR (INTEGRATED FORWARD-LOOKING

SYSTEM)

GENERAL DESCRIPTION

The Contractor shall provide and install a three-dimensional forward-looking sonar (3D FLS) for navigation and displaying the seafloor and any in-water obstacles in front of the vessel. The forward-looking sonar shall be part of an Integrated Forward-Looking System (IFLS) that creates a digital terrain map (DTM) of the river bottom or seafloor. The sonar system shall meet all ABS and USCG requirements.

REQUIREMENTS

A forward-looking sonar shall be provided and installed for the dredging operation, with the transducer array mounted flush with the hull or in a cavitation-free transducer housing located forward of the hopper and installed in accordance with manufacturer’s instructions. The system shall be provided with a data acquisition unit, display, and storage system hardware and software. A display shall be located at the dredge operator’s station.

An Integrated Forward-Looking System (IFLS) shall combine the on-site data generated by the multibeam bathymetric forward-looking sonar system with the Dynamic Positioning/Dynamic Tracking (DP /DT) data for the Dredge Track Position System (DTPS). See Contract Paragraphs C524 and C608.

The IFLS System shall be effective over the Operating Profiles listed in contract Paragraph C002.

The IFLS shall integrate actual real time onsite bottom mapping data with the DP/DT system for accurately steering the vessel along planned dredge tracks along the digital terrain model (DTM).

It shall also use the DTM information to achieve better feed-forward control of the DP/DT system which in turn makes for better track and speed control capability at the lowest fuel consumption and emissions. Along the dredging track, soil property variations shall be used to govern vessel speed variations and automatic dredge pump, jet pump and visor control settings (see Contract Paragraph C524); thus, the suction properties are precisely adjusted to the type of soil and further enhancing the regularity of the seafloor after dredging.

The sonar system shall be powered from UPS power.

Transducer cables shall be installed as described in Contract Paragraph C326.
