Part 2 Practicability and compatibility with the ship’s design, operation and existing systems, as well as other technical details
2.1 What are the performance parameters of the system? (Essential to its control.)
2.2 Does the system allow for controlling the performance of the treated water as regards the D-2 Standard during the treatment process? If so, describe it.
2.3 How long does it take to treat a given volume of ballast water? At what temperatures?
2.4 Are post-treatment residence times required before discharge, and if so, what are the required times?
2.5 Does the system require complete re-circulation of the ballast water? If complete re-circulation is needed, how many re-circulations are required to meet the requirements of regulation D-2 of the BWM Convention?
2.6 Is the system automated? Completely or partially? (Make comments, providing technical details on the automation level and scope and on the system’s controls.)
2.7 In case yes, how to control? (Algae and/or organisms detector or monitor, corresponding recorder, etc.)
2.8 Would this control system be reliable, accurate and sufficiently capable of dispensing with the collection of ballast water samples to check compliance with the D-2 requirements in the laboratory? (With the understanding and acknowledgement of such capacity by port State control inspectors, and with a pertinent certification for this purpose.)
2.9 Is the control system also suitable for adjusting the treatment process (such as, for instance, to intensify or reduce the electric current supply to an electrolytic cell used to generate the Active Substance and/or to dose the Active Substance or chemical injection for water treatment)? (In case yes, please provide details.)
2.10 In the case of a ballast water management system that requires the Active Substance to be supplied to the ship, is there a dosing pump for the injection of such substance? Is the control of such injection by the dosing pump automatic?
2.11 Is the system supplied with devices that facilitate collecting more representative samples of ballast water (in compliance with the Guidelines (G2))? In case yes, provide details.
2.12 When the system needs to receive the Active Substance or chemical, indicate the tank capacity required for that (in cubic metres), show the product supply arrangements to the ship and to the system, as well as other related details.
2.13 Provide information about the worldwide net of suppliers capable to provide the required Active Substances used by this ballast water management system to the ship. Inform the main ports where this supply can be effectively and promptly done.
2.14 Which were the results of the system’s environmental tests required by the Guidelines (G8)? Summarize them.
2.15 How the shipboard tests required by Guidelines (G8) were performed? Inform the trip conditions, mentioning the ship’s route, the ocean areas and latitudes involved, as well as the season and the total period of time for performing these tests. Inform also on which type of ship the shipboard tests were performed and how many trips were made for this purpose.
2.16 Inform if there were some failures during the system’s environmental, land-based (these performed at a land-based testing facility) and shipboard tests, which implied on certain modifications and corrections of the ballast water management system under development, and which were the adjustments done to solve them and to obtain the type approval certification for the system.
2.17 What is the additional workload on board introduced by the ballast water management system and the staffing requirements for the system?
2.18 What is the highest sea state in the Beaufort scale in which the system can still operate?
2.19 Does the ballast water management system’s operation affect the corrosion rate and the wastage of tanks, pipelines or any other equipment of the ship’s ballast system associated with it?
2.20 Can the system be affected by incrustation that could lead to a drop in pressure and/or to a reduction in the flow rate? If so, indicate the percentages.
2.21 Is the system applicable to existing ships?
2.22 What are the installation requirements for the system? What are the system’s requirements for deck space, weather-tight space or machinery room space?
2.22.1 Can the system only be installed during a dry-docking period?
2.22.2 Can the system be installed and evaluated while the vessel is alongside the pier, in service or removed from service?
2.23 What are the maintenance requirements for the system?
2.23.1 Can the system only be maintained during a dry-docking period?
2.23.2 Can the system be maintained available dockside?
2.23.3 Is specialist maintenance expertise required and is this available worldwide?
2.24 Are the ship’s other functions and systems independent from the ballast water management system’s operation?
2.25 Could the system be integrated into the other ship systems?
2.26 What are the calibration requirements of the system?
2.27 What are the results of the following system’s environmental tests and evaluations?
2.27.1 exposure to various environmental extreme conditions including heat, cold, humidity, vibration, more critical conditions of ship’s list and trim, and power fluctuations?
2.27.2 reliability and durability?
2.28 What is the expected life of the system?
2.29 Regarding land-based and full-scale shipboard tests, describe the experiments, equipment, and system configurations which were used, as well as provide a list of technical documents to be consulted to get additional information on these issues.
2.30 Has the system been assessed, by a competent Authority and/or by a recognized organization, as suitable for onboard application?
2.30.1 for new ships?
2.30.2 for existing ships?
2.30.3 In affirmative case, list all installation approvals that have been granted with the correspondent granting authority (or recognized organization)? (This question is a complement to the question of Part 1 related to “ballast water management system list of reference”.)
2.31 Are there any individual system requirements, which affect the existing layout of the ship, like watertight envelope, generator capacity, etc.?
2.32 What are the requirements for on board storage of component spares and consumables?
2.33 What are the consistency results of multiple manufactured units of a system?
2.34 What type of supply shall the system need for its functioning on board – such as: electric energy (voltage; frequency; expected power required); compressed air (defining the pressure and flow rate); fresh and/or salt water (respective pressures and flow rates), etc?
2.35 Can the system be considered or categorized as an alternative ballast water management system in accordance with the provisions and purposes of the regulation B-3.7 of the BWM Convention? If so, provide further comments and considerations about this issue.
2.36 Can the system be installed on ships with special arrangements of ballast system, such as: bulk carriers with various overboard discharge points for deballasting; and tankers with one submerged pump inside each ballast tank (ships which do not have pump room too)? If so, indicate how and provide details of these special arrangements for installation of the ballast water management system.
