Marine architects select a pollution control system for a marine vessel or structure based on several factors, including:
1. Environmental regulations: The first consideration is the environmental regulations that apply to the vessel or structure. The type of pollution control equipment required will depend on the nature of the pollutants that need to be controlled, the discharge limit values for each pollutant, and the recommendations of regulatory bodies such as the International Maritime Organization (IMO).
2. Vessel/structure specifications: The designer needs to consider the size, shape, weight, and other specifications of the vessel or structure when selecting a pollution control system. For example, the equipment selected must fit within the available space on board the vessel, and meet any engineering requirements such as weight restrictions.
3. Type of pollutant: Different types of pollutants require different pollution control systems, such as oily water separators, sewage treatment plants, or exhaust gas scrubbers. The designer needs to determine the type of pollutants that will be discharged, as well as the quantity and quality of each pollutant.
4. Operational factors: The designer must also consider the specific operation of the vessel or structure when selecting a pollution control system. For example, the type of equipment selected for a cruise ship may be different from that for an offshore platform, based on factors such as frequency of use, climate, and duration of operation.
5. Cost: Finally, the designer needs to consider the cost of the pollution control system and its associated maintenance, installation, and operational costs, to ensure that it meets budget requirements.
