Safety
6.2 The documentation for systems should list any safety hazards to the vessel, crew, port personnel and general public health.
6.2.1 Do ballast water management system processes present any health or safety risks?
.1 Are there, for instance, high voltage components, processes involving high heat, cryogenic processes, use of radiation or lasers, chemical reactions whose constituents or by-products present any risks, or high pressure liquids or gases?
.2 If so, what safety provisions are incorporated into the design and operating procedures for the system?
6.2.2 Are there components with dissimilar metals exposed to saltwater?
.1 If so, what safeguards have been incorporated to protect the ship's structures, pipelines, equipment, valves and accessories against corrosion and excessive wastage?
6.2.3 Does the system involve the use of active substances or components with special storage or handling needs?
.1 If so, how have these needs been addressed, by the system and in the operation and maintenance manuals?
6.2.4 If the system operates during ballast operations, including uptake, discharge or transfer, are there adequate safety interlocks and failsafe measures to ensure vessel stability and structure is not compromised?
6.2.5 In the event of a vessel casualty does the system pose any additional risks?
.1 Are there additional risks in the event of flooding?
.2 Does vessel power loss present any additional risks?
Environmental acceptability
6.3 Submissions should address possible environmental impacts including the interaction of the components and processes of the management system with the environment, both as a function of normal use and in the event of system failure or vessel casualty.
6.3.1 Does the system involve any conditioning of treated ballast water required prior to discharge into the environment?
6.3.2 What are the characteristics of any additional air emissions, which result from the use of the management system?
6.3.3 Does the use of the management system result in the discharge of ballast water at other than ambient temperature?
6.3.4 Are there waste streams such as the residue of any filtering process or centrifugal concentrate?
.1 If so, what are the characteristics of the waste streams?
.2 What is the planned disposition of the waste streams? Are they suitable for discharge or must they be disposed of on-shore?
.3 If discharged, how quickly do the waste streams dissipate following discharge?
6.3.5 Are there system components or processes which use active substances or produce residuals or by-products which present problems in handling, storage or disposal?
6.3.6 What special disposal concerns, such as batteries or lead-containing fixtures, are part of the system?
6.3.7 Which system components, if any, present any risk to the environment if damaged as a result of a vessel casualty?
Practicability
6.4 Submissions should address the performance capabilities of the system as well as operational requirements.

.4 What are the flow or capacity capabilities of the system? Are there limits to the scalability of the system?
6.4.4 What are the installation requirements for the system?
.1 Can the system only be installed during a dry-docking period?
.2 Can the system be installed and evaluated while the vessel is alongside the pier, in service or removed from service?
.3 Are there any individual system requirements, which affect the existing layout of the ship like watertight envelope, generator capacity, etc.?
6.4.5 What are the maintenance requirements for the system?
.1 Can the system only be maintained during a dry-docking period?
.2 Can the system be maintained in a dockside availability?
.3 Is specialist maintenance expertise required and is this available
worldwide?
6.4.6 What are the requirements for on-board storage of component spares and consumables?
6.4.7 What are the calibration requirements of the system?
6.4.8 What are the consistency results of multiple manufactured units of a system?

6.4.10 What are the results of system reliability and durability testing?
6.4.11 What is the expected life cycle of the system?
6.4.12 What are the results of testing the system's exposure to various environmental extremes including heat, cold, humidity, vibration, and power fluctuations?
Cost effectiveness
6.5 Submissions should indicate known or estimated costs of installation and operation.
6.5.1 What is the known or estimated cost of installation for vessels at the time of construction, and for retrofitting to an existing vessel?
6.5.2 What is the known or estimated cost to treat a unit of ballast water, either by volume or volume per unit time?
6.5.3 What are the ship staffing requirements for system installation and/or operation?
6.5.4 What are the known or estimated maintenance costs on an annual basis?
6.5.5 What are the known or estimated costs of component spares and consumables on an annual basis?

Biological effectiveness
6.6 Submissions should supply the quantitative data and interpretations from previous experiments and trials that are directly applicable to the current system and its ability to meet the standard of Regulation D-2. Analytical techniques used in determination of the status of organisms and pathogens (living or dead) should also be described.
