No void spaces will be left behind bulkheads adjacent machinery spaces. Structure The effects of vibration on the main hull, superstructure and masts etc., must be considered at a very early stage, and the deisgn of the structure (scantlings, continuity of engine seating, etc.) shall be undertaken with care in order to minimize the transmission of vibrations and noise. Attention shall be paid to prevent the risk of resonance between structural elements and fitted equipment. Local stiffening of structure, in order to increase the local stiffness, will be provided in order to have the minimum possible transmission of structural noise in to the structure. Sound Insulation and Damping Treatment As general criteria, sound insulation is to be applied as required in order to satisfy the noise rating levels set forth later in this section. Special care is to be given to sound insulation where cabins are adjacent to fan rooms, stairways, pantries and public spaces, etc. Machinery adjacent to accommodation areas shall be suitably supported with adequate resilient mountings in accordance with Builder standard practice. The transmission of structure-borne noise to accommodation areas, for example where electric cabling, pipes and equipment are attached to the hull structure, or pass through bulkheads and deckheads, forming boundaries to machinery spaces, shall be attenuated by means of resilient mountings, insulated attachments and pipe hangers, etc. Adequate insulation in machinery spaces shall be provided to prevent the passage of airborne noise into accommodation areas, In the Owner's and guest cabins, where applicable, the wall coverings and ceilings shall be elastically mounted to the yacht's structure; this will include the application of mineral wool and added mass layers or damping as per Builder's standard practice. Floating floors or suspended floors will be fitted in the Owner's and guests' accommodation, public spaces and where necessary in order to guarantee noise limits. Insulation under floating floors to be tight beneath. In way of Owner's, guests' and crew cabins, independent double wall structures to be arranged if necessary, for acoustic privacy, with mineral wool in-fills in the cavities. Panels will have added mass layers in necessary. Machineries and Propulsion Installation of suitable mountings will be taken into consideration wherever necessary. The main engines will be elastically mounted. The generating sets will be elastically mounted and fitted win acoustic enclosures. The exhaust of the main engines at medium and high ship speed shall be led out under water. The exhaust of the main engines at medium and high ship speed shall be led out under water. The exhaust of the main engines at low ship speed shall be led out above water. Air ducts shall b adequately dimensioned to keep the air velocities low. Care will be paid to respect manufacturer's parameters with regards to Back Pressures. Pumps, generators, exhaust pipes, ventilation fans, compressors, air conditioning units, transformers for electronic units, hydraulic elements and similar noise-emitting machinery to be mountings, the ship foundation will be of suitable high stiffness as appropriate to achieve the greatest effectiveness. Flexible hoses and electrical cables to be installed to compensate for the motions of any flexibly mounted equipment. These fittings shall meet the requirements of the Classification Society and Regulatory Bodies and will handle the maximum design movements of the mounted equipment without over-stressing or deforming the attached piping or cables. All flexible pipes in machinery spaces are to be sheathed/armoured in accordance with Classification Society and Regulatiry Bodies requirements. Propulsion and Hydrodynamic The propellers will be designed in order to minimize, as far as practicable, generation and transmission of noise into the hull. This will include 5 blades, skewed propellers with good tip clearance (>15%). To avoid noise, all underwater parts such as zinc anodes, water inlets and outlets, stabilizer fins, openings of the bow thruster etc, are hydrodynamically configured. Particularly attention will be paid in the vicinity of guest accommodation areas in order to eliminate noise from running and dripping water. Prop speed or equivalent treatment to be applied to propellers before yacht in launched. Noise Targets The Builder must achieve the following noise targets. The values stated below must be intended in dB(A) and measured following the procedures stated in the IMO Code on Noise Levels on Board. Two different operating conditions will be measured: Transit condition- -Motor Yacht cruising in quiet sea (sea state less than 2) and calm wind (wind force less then Beaufort 3) -Design draught -Speed: 10 knots -Unrestricted deep-sea waters -Straight course, limited rudder angle (max. 2 degrees to each side) -Fully furnished -Exterior doors shut -Air conditioning in cabins in normal operating conditions -Bow thruster not in operation -Stabilizers switched on -Excluding human activity Harbour/anchor conditions -Yacht at rest with calm sea and no wind -1 sound enclosed Generating Set running -Air conditioning in cabins in normal operating conditions, engine room ventilation in harbour mode -Stabilizers switched on -Doors and windows closed -No maneuvering and human activities Noise Limits in Different Yacht's Operating Conditions - dB(A) Owner's cabin: Transit 50 dB(A), Harbour 42dB(A) VIP/Junior Suites: Transit 58 dB(A), Harbour 45dB(A) Crew Cabins: Transit 58 dB(A), Harbour 45dB(A) Main Deck Saloon: Transit 58 dB(A), Harbour 45dB(A) Sky Lounge: Transit 58 dB(A), Harbour 42dB(A) Bridge: Transit 58 dB(A), Harbour 42dB(A) Captain's Cabin: Transit 58 dB(A), Harbour 45dB(A) Crew Mess: Transit 58 dB(A), Harbour 45dB(A) The noise level in all the sanitary spaces and dressing rooms located in or adjacent to the above-mentioned areas shall not be more than 3 dB above the stated level of the corresponding area. Acoustic Privacy The design requirements for reduction between cabins (doors closed) will be in accordance with the speech privacy ratings listed below. Measurements will be performed in dead ship. Following acoustic privacy levels are to be met. Owner's, VIP's and Guest's cabins: 35 dB Crew cabins / crew mess and lounge: 30 dB |
