• Dimensioned drawing of the docking block

• Total area covered by the docking blocks for each plan

• The maximum block loading (kips/foot-squared)

A. NOISE & VIBRATION PREDICTION ESTIMATE

During Phase II of the contract, the Contractor shall retain the services of an acoustic engineering firm specializing in marine vessel noise assessment, abatement, and vibration reduction to prepare a vessel noise and vibration prediction estimate. The noise and vibration predication estimate shall be designated 874-

C180-01 NOISE & VIBRATION PREDICTION. Possible sources for the prediction services include:

• Noise Control Engineering (Billerica, MA (978) 670-5339)

The acoustic engineering consultant firm shall perform a forced response FEA vibration analysis which shall predict the vibration response of the decks of all spaces that result from operation of major machinery.

The noise prediction estimate shall provide results for the compartments/locations listed below in paragraph

C of this Section.

The report shall include recommendations for improving the conditions. The Contractor shall be responsible for implementing the required noise abatement recommendations to achieve the noise levels listed in paragraph C of this Section.

B. NOISE & VIBRATION SURVEY

The Contractor shall retain the services of the acoustic engineering firm that developed the noise and vibration prediction to complete a Noise and Vibration Survey at the conclusion of Tests and Trials. The airborne noise and vibration levels shall be measured in all compartments, deck locations, and spaces identified in paragraph C of this Section. The noise and vibration survey shall be designated 874-D180-01 and titled: NOISE & VIBRATION SURVEY.

A report shall be prepared by the Contractor detailing the survey and test procedure and results. The report shall include sketches of the spaces measured with recorded sound levels denoted at the location of their measurements. Reduced size general arrangement drawings shall be acceptable for this purpose. The

Contractor shall take corrective action as necessary to achieve the required noise criteria. The report shall designate any compartments which present a noise hazard according to OSHA regulation, 29 CFR 1910.95

“Occupational Noise Exposure”. See Contract Section E05 for test requirements.

C. NOISE LIMITS

The noise limits for the vessel shall be ABS Guide 163 “Crew Habitability on Workboats”. The Contractor shall be responsible for development of a noise treatment plan to achieve the HAB(WB) sound pressure levels listed in Section 4, Table 1 as summarized below.

Hold Spaces 75-dB(A)

Cabins 60-dB(A)

Other Crew Spaces 65-dB(A) Galley & Mess Area 65-dB(A)

Pilothouse 65-dB(A)

Exterior Decks 85-dB(A)

The noise survey during tests and trials shall be based on the average of the broadband sound pressure levels taken at various representative locations in the reverberant field of the compartment or space in question.

Values should be measured using the A-weighted scale with the meter set for slow response.

If noise limits are exceeded, the Contractor shall correct all deficiencies that are identified.

D. VIBRATION LIMITS

The vibration limit for the vessel shall be ABS Guide 163 “Crew Habitability on Workboats”. In addition to the HAB(WB) limits presented by Section 3, Table 1 of this guide for multi-axis vibration, no single axis weighted vibration component shall exceed 2.5mm/s-rms in the x, y, or z directions when considered individually for any measurement location in accommodation or work spaces.

The Contractor shall measure these velocities in the manned spaces during the testing phase of this Contract and provide a written report, per Contract Section E05. If the vibration limits are exceeded and it is found that the excess is due to poor workmanship or quality control, the shipyard shall correct whatever deficiencies that are identified by the excessive vibration.

E. NOISE & VIBRATION CONTROL - GENERAL

In addition to specific requirements contained in this specification, the Contractor shall implement the following control measures to ensure the criteria are satisfied:

• Provide an effective noise barrier around high noise spaces to prevent noise transmission to adjacent spaces.

• Provide sound absorbing material around high noise spaces to reduce contribution of reverberant noise within the space.

• Install vibration isolators for all diesel engines, generators, and rotating machinery such as pumps and fans in order to reduce noise and vibration transmission through the structure.

• Provide flexible mounting of ventilation and other service lines.

• Ensure that all pipe and duct joints are tight and that all penetrations through spaces are sealed.

• All pipe connections to the engines and generators should be of the flexible type.

• Use low noise components, e.g. tighter tolerances.

• Ensure the natural frequencies of the foundations of hard mounted equipment to be at least 30 percent greater than the disturbing frequencies of the equipment.

• Ensure that the local stiffness of the foundation supporting the resilient mounts to be at least 10 times the stiffness of the isolator it supports to result in adequate vibration isolation.

• Ensure that the natural frequencies of the resilient mount systems be sufficiently far from the disturbing frequencies (at least 30 percent of the nearest mode). If this condition cannot be satisfied, the vibrational force transmission to the foundation should be studied in greater detail and corrective measures taken to meet an acceptable isolation performance.

• If acoustic spray-on insulation is to be used, design and application shall be in accordance with

Contract Section C436..

C185 TEST AND TRIALS

This vessel and its component parts shall undergo testing and trials in accordance with Contract Section E, Section E05, Trials, Tests and Demonstrations.
