4 3 NAVAL GE The DINAK GE NAVAL range is made up of modular ducts with double rockwool insulation and has a complete anchoring system and accessories specially designed for shipping facilities. Given the high performance reached by the DINAK GE NAVAL range, its excellent aesthetic finish and the ease of installation, this is the best option in all types of medium or high temperature gas conduction (up to 600ºC) that are subject, or not, to high process pressures (up to 5000 Pa). ADVANTAGES OVER TRADITIONAL EXHAUST SYSTEMS Weight reduction. Around 50% approximately. Simple installation. It is not necessary to cut, weld the pieces together or to use lifting equipment. Fast installation. Prefabricated system, manufactured with strict quality controls according to an integrated structure in the manufacturing control system. Finished system, it is not necessary to lag the ducts or coat them with exterior enclosures. Ducts are made out of stainless steel, have long durability and the system is guaranteed. Excellent aesthetic finish. Calculation and design of the facilities is available from DINAKs technical department. Flexible system, allows for design modifications during installation in addition to repairs in the event of accidents. No transmission of expansion to the structure of the vessel (without the need for compensators or expansion joints interwoven into the ducts).

5 APPLICATIONS OF THE NAVAL GE RANGE 4 The versatility of the Naval GE range makes it possible to integrate exhaust ducts in several elements of the ship as shown below. Incinerators On board combustible waste management: Fuel: Diesel, LPG, NG Process temperature: ºC Maximum outlet pressure Maximum: 3000 Pa Main motors assigned to the main propulsion of the ship Motor pumps/auxiliary motors Generators Set of Motor + Alternator Electric energy production Boilers/steam generators Production of hot water for sanitary use Pressurised water vapour Fuel: Diesel, LPG, NG Process temperature: approx ºC Maximum outlet pressure Maximum: 5000Pa Fuel: Diesel, LPG, NG Process temperature: up to 600ºC Maximum outlet pressure Maximum: 5000Pa Fuel: Diesel, LPG, NG Process temperature: approx ºC Maximum outlet pressure Maximum: 5000Pa Fuel: Diesel, LPG, NG Process temperature: approx ºC Maximum outlet pressure Maximum: < 200 Pa

6 5 FEATURES OF THE DINAK GE+ SYSTEM FEATURES Individual expansion absorption at joints The inner and outer walls work together on the male end of straight sections, while on the female end the inner Wall expansions freely with the effects of temperature. The outer wall of the straight elements (202) includes a bellow on the male end, which ensures correct absorption of the expansions in the outer wall. This way, it is not required to install before each offset extra elements to absorb the expansions. Gas tightness Gas tightness class H1 (up to 5000 Pa) at the connection point between elements by means of a silicone joint on the outer wall. The locking band press the joint securing the tightness and at the same time covering it and protecting it from external agents. Outer Wall: Butt welded in every piece of the chimney. Temperature class T600 (up to 600ºC) The range is heat-insulated using rockwool with a thickness of 30mm and a density of 130kg/m³ whereas the insulation has a thickness of 50mm and a density of 100kg/m³. Both ranges are CE-certified for the evacuation of exhaust gases produced by power generators and fire pumps. Their walls are not guided by any thermal bridge elements. The most suitable range for a specific installation will be determined depending on the maximum temperature required on the outer wall, the type of installation and the prevailing regulations. Stable and resistant The overlap between elements is 40mm, which confers stability and robustness to the system, especially to horizontal sections and during its installation. The locking bands fit directly to the outer wall, giving rigidness to the ensemble and making the silicone joint redundant to ensure the mechanical stability of the chimney. Reliable and easy to install It is not required to apply lubricant nor apply high pressure to the elements to carry out the installation. The installation of the outer seal is simple and, thanks to its position in the chimney, it is possible to verify visually that it has been correctly installed. Therefore, it is a completely reliable system. It can be totally dismantled.

13 ALTERNATIVE GE RANGES 12 GE50 The GE50 range has been tested and installed for years in all types of industrial and marine installations. The and GE 50+ ranges are supplemented to service applications that need diameters larger than 600 mm. The selection criteria in this line and range of service, regarding pressure and maximum temperature, are shared with the GE+ range, meaning up to 5000 Pa of excess pressure and 600ºC in continuous operation. Diameters and weight table Ø Dext Kg/m GE100 For those cases where the exterior temperature limitation of the ducts is extreme, DINAK offers clients the GE100 range with the same essential characteristics as the rest of the GE range but with a greater thickness of insulation.

14 13 DESIGN CRITERIA Material and range selection guide The DINAK GE Naval range is available in different diameters and insulation configurations and adapts to the requirements demanded for each application. For example, a duct may be limited so that the process it services does not exceed a certain speed (limitation of maximum pressure or noise generated, for example) or a certain temperature of the exterior wall. In addition, the range provides different combinations of materials for the gas ducts and the exterior wall in order to reach an optimal solution in each project and application.

15 INSTALLATION CRITERIA 14 Supports Selection criteria for anchorages Horizontal Stages For easy installation, the use of 86N anchorages are recommended and the installation of intermediate 80N anchorages is also valid. Vertical Stages Intermediate 80N anchorages must always be used, with the exception of finishing touches that may have special considerations (See page 15). Anti-vibration kit In order to avoid vibrations in the general structure of the ship, isolating the ducts is recommended. The DINAK GE Naval range has anti-vibration kits that are specially designed for this purpose, also allowing the avoidance of galvanic corrosion by contact of metals with different electrical potential. DINAK recommends installing the kit to each anchorage of the system. Installation and position of the anchorages. The recommended installation is shown in the following charts as a general guide. In straight sections In straight sections, anchorages must be placed at least every 2 m. For deviations As general criteria for deviations in the layout, a maximum distance between anchorages must be at 2 m measured on the axis of the duct and it will be taken into account that at least one anchorage is to be installed as close as possible to one end of the deviation. For diameters larger than 600 mm For diameters larger than 600 mm and the GE100 range, consult with DINAK for the best possible configuration of anchorages. Installation of the anti-vibration kit: The kit consists of a carbon steel plate (1) + rubber seals that insulate the duct of the structure. This kit is screwed on (according to the attached sketch) to the 80N/86N attachment and is welded to the carbon steel plate primed on the ship s structure. (1) Other materials are available on request L1 + L2 + L3 + L4 < 2m (axis measurements)

16 15 INSTALLATION CRITERIA Straight Elements : 020 or 202 The straight element 202 with dilator is used for applications with high gas temperatures (greater than 300ºC) in the case of main motors, generators, motor pumps, incinerators, etc. The 020 is used for applications with gas temperatures below 300ºC, such as boiler applications, steam generators, etc. Connection elements between horizontal and vertical This connection is generally achieved with a 90º elbow pipe + drain, code 43N or with a 45º elbow pipe with drain (code 40N) and another 45º elbow pipe (code 040). This prevents the possible entry of water to the equipment. Terminal elements This connection is generally achieved with a 90º elbow pipe + drain, code 43N or with a 45º elbow pipe with drain (code 40N) and another 45º elbow pipe (code 040). This prevents the possible entry of water to the equipment. High resistance to corrosion Use of AISI-316L Avoid contact of external water with the main engines and equipment: Design prevents water from entering the insulation and minimises the entry of water into the ducts; different terminals with multiple combinations of exit angles. Special straight element module with perimetral collection and drain (code 55N) Specific design to seal the cover. Water cover with a lower band to overlap with the exit neck of the cover. Terminal Support: According to the standard design of this figure, it is not necessary to add an additional exterior support or additional anti-vibration systems. In the case of increasing the free height or the cantilever, DINAK has all the stainless steel AISI-316L pieces described in this catalog to obtain the necessary design. Alternatively other elements can be designed with specific geometries, materials and specific thicknesses.

17 INSTALLATION CRITERIA 16 Fixed points and length compensators systems One of the advantages of the DINAK system is that, along the entire length of the ducts, these do not transmit expansion at the anchorage points to the structural elements of the ship or to other equipment. However, certain equipment such as silencers, spark arresters, catalysts, motors, scrubbers, etc., can experience large expansions towards the DINAK ducts, which, if left unchecked and uncompensated, would cause large overloading of the ducts. In these cases, it is necessary to compensate for these dilations, also avoiding the transmission of vibrations, and DINAK can optionally supply compensation systems and specific anti-vibration supports. Connection between the outlet of the motors and the DINAK duct The fixed point shall always be made after the dilator/anti-vibrator (A) of the engine exhaust outlet and on the side of the modular DINAK duct (B). Objective B C D Eliminate the transmission of vibrations and expansions A DINAK solution Installation of supporting arms (C)* bolted to the flange Place fixed anti-vibration points (D)* to these arms fixed to the structure of the ship directly or with an auxiliary substructure. Connection with silencers / other equipment with axial dilators The fixed point or points are made in the case that the expansion of the equipment (d) at any of the connection points is greater than 3mm (d>3mm) Objective Eliminate the transmission of expansion and overloads. DINAK solution Install supporting arms (A) bolted to the coupling flange. Place fixed anti-vibration points (B)* to these arms fixed to the structure of the ship directly or with an auxiliary substructure. In the example shown, the silencer expands less than 3mm on the right side, and a larger amount on the left side. (1) It is assumed that the weight of the silencer/equipment is supported by the overall structure of the ship, for example, with the help of anti-vibrators on the supports (C) and the stabilisers (D). D d < 3 mm A B C

18 17 ACCESSORIES Length compensators and anti-vibration devices As previously explained in this catalogue, the double wall DINAK ducts do not transmit significant expansions to the rest of the equipment, installations or the ship s structure. However, in a conventional manner, it is customary to introduce equipment into exhaust systems that generate large expansions and vibrations. If not foreseen, they cause large deformations and/or overloads to other equipment and to the ship s structure itself, in addition to causing noise problems. Compensators or Expansion joints These are introduced to the system should it be necessary to absorb important expansions generated by certain equipment (for example, main silencers of engines). Stabilisers These control movements in a single direction and avoid the transmission of vibrations by equipment that generates them. Fixed point support Support element which allows the anti-vibration fixed point to be attached with bolts. Fixed anti-vibration point These support the static and dynamic loads transmitted by equipment that experiences expansion and vibration toward the ducts while it is operational. Acoustic attenuation systems As an option, Dinak offers clients standard or customised acoustic attenuation systems according to the actual needs of the installation. Examples of attenuation systems Relaxation-absorption silencers: Design especially suitable for medium to high power Motors / generators. Possibility of incorporating an anti-spark system. Possibility of incorporating a drain. DINAK Silenk Modular attenuation systems fully compatible with DINAK GE Naval range. Easy installation, absence of fixed points and perfect aesthetic integration. Excellent absorption capacity at medium and high frequencies. Especially suitable for boilers and incinerators. Terminals and custom elements In addition to standardised terminals (see page 15), DINAK can supply different terminal options, whether for the technical requirements (for example: materials, special geometry ) or aesthetic requirements. For other special items, please consult with DINAK.
