B. DESCRIPTION OF WORK

The contractor shall develop a dry-docking plan for the vessel. The dry-docking plan shall be numbered 848-C170-01 and titled: DRY DOCKING PLAN. The dry-docking plan calculations shall be numbered 848-C170-02 and titled: DRY DOCKING PLAN CALCULATIONS. Both documents shall be submitted to the Government for review and approval during Phase II.

Following the completed and approved incline results, the Contractor shall update these drawings and reports reflecting the as-built condition and submit it (as 848-D170-01 and 848-D170-02) to the Government for review and approval. For additional requirements on drawing development and submission for review, see Section H12 of this contract.

The dry-docking plan shall be developed to show the blocking arrangement. The blocks to be used for docking shall be the standard dry-docking blocks from the US Army Corps of Engineer’s Ensley Shipyard & Repair Facility in Memphis, TN as shown on the reference drawing. The blocks used for the docking shall hold the barge in the following loaded condition:

50% fuel oil 50% lube oil 50% potable water Empty sewage tank Empty waste oil tank Empty ballast tanks Crawler crane on deck (weight to be provided by the Government)

The plan shall show all major hull structure on the bottom including all transverse and longitudinal bulkheads connecting with the bottom shell, as well as anodes, sea chests, and other features which could interfere with the setting and shifting of docking blocks.

The plan shall also include an alternate blocking arrangement to allow for the servicing of all areas of the bottom of the barge. No block shall remain in the same position on the alternate blocking plan as it was on the primary dry-docking plan.

The blocks shall be located to evenly distribute the loads and avoid undue stresses within the hull structure. Blocks shall be located in way of main structural, longitudinal, and transverse bulkheads wherever possible. Where blocking is located on frames other than bulkheads, appropriate docking brackets shall be designed and installed within the hull. Docking bracket details shall be shown on the structural drawings. If the end(s) of the vessel are unsupported, the contractor shall provide calculations with the plan submittal showing that the hull strength is adequate to handle the cantilevered load.

The dry-docking plan shall contain all of the information contained in the reference drawing to include:

Dimensioned drawing of the docking block Total area covered by the docking blocks for each plan The maximum block loading (kips/foot-squared) Lightship weight determined by the Inclining Experiment, its LCG and VCG o For the Engineering Phase submittal, substitute the weight from the most recent revision of 848-C115-01.

Full load weight as determined by the as-built Stability Calculations and its LCG Load condition for which the plan was developed

C180 NOISE & VIBRATION

A. NOISE & VIBRATION SURVEY

The Contractor shall retain the services of an acoustical engineering firm to complete a Noise and Vibration Survey at the conclusions of the Tests and Trials. A possible source for the survey is

Noise Control Engineering (Billerica, MA (978) 670-5339). The airborne noise and vibration levels shall be measured in all compartments and deck locations. The noise and vibration survey shall be designated as 848-D180-01 and titled: NOISE & VIBRATION SURVEY.

A report shall be prepared by the contractor detailing the survey and test 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 will be acceptable for this purpose.

The report shall describe any compartments which present a noise hazard according to OSHA regulation, 29 CFR 1910.95 “Occupational Noise Exposure” and USACE ER 385-1-89.

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 excessive noise is found to be caused by poor workmanship or quality control, the shipyard shall correct whatever deficiencies that are identified by the excessive noise.

B. VIBRATION LEVEL TARGETS

The vibration limit for the vessel shall be the SNAME Technical & Research Bulletin 2-25 SHIP VIBRATION AND NOISE GUIDELINES (1980) as presented in Principles of Naval Architecture, Volume II, (Figure 35, page 306, 1988 Edition). The vertical vibration velocity and acceleration shall not exceed the maximums of Zone II. This criterion is the upper limit of vibration level that is noticeable but usually shall not adversely affect vessel personnel.

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, the deficiencies shall be corrected by the contractor.

C. NOISE & VIBRATION CONTROL - GENERAL

In addition to insulation requirements, generator and exhaust mounting details provided in this specification, the contractor shall implement the following control measures to ensure the target criteria are satisfied:

Effective noise barrier around high noise spaces to prevent noise transmission to adjacent spaces, and sound absorbing material around high noise spaces, to reduce contribution of reverberant noise within the space.

Install vibration isolators for all diesel 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.

Ensuring 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 of 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.

C185 TESTS & TRIALS

The barge and its component parts shall undergo testing and trials in accordance with Section E of the contract.
