Ballast Water Treatment Systems and Installation
LR rules our approach SAFETY & RELIABILITY GOAL Prescriptiv e requiremen ts Assessing Risk Risk based solution
BWTS: LR Specific ship installation approval Submission and review of ship s specific installation plans against LR Rules which covers: Safe integration of BWTS with other systems Effects on other shipboard systems Installation location Stability, structural, fire and watertight integrity Piping and electrical cable routing Contingency measures to mitigate operational hazards Appraisal of components outside scope of supply from BWTS manufacturer Electrical installations in hazardous areas Safe storage and handling of chemicals, if any
Feedback from retrofits Always undertake onboard measurements Consider impact of BWTS on the flexibility of the ballast system Is it possible to use fire pump in case ballast pump is out of service? GRE vs steel piping? Effects on fire & safety, stability For systems that require galvanised piping, specify compression fittings to prevent damage to pipe linings Minimise ballast water piping in the engine room Keep BWTS close to switchboard to simplify cable runs How the switchboard impact to Arc flash assessment, if any
Feedback from retrofits Additional services may be required: Fresh water supply may be required Air supply to back flush filters and controls Lighting Fire detection Fire extinguishing Lifting appliances Maintaining fire protection Penetrations through bulkheads Structural integrity if separate BWTS room is required
Feedback from retrofits Access for installation Getting major items of equipment into position Is it possible to get the spanner onto the bolt head? Maintenance footprint Automation Hotel arrangements and LSA for install team (if on passage) Update ship s drawings Crew training / documentation
Feedback from retrofits Key hazards per type of BWT system including areas of safety concerns. Size and footprint of the system. Certification required and installation approval process. Electrical power balance. Installation in hazardous areas and/or cargo pump room. Location of BWT room and categorisation of the space with respect to fire protection. Treatment of the Aft Peak Tank. Stripping of ballast tanks. Gravity ballasting deballasting. Corrosion / Erosion issues.
Systems specific issues Electro chlorination systems are salinity dependent Full flow systems: Unable to treat fresh water Side stream systems: side stream can be dosed with salts At lower water temperatures electricity consumption increases At very low temperatures systems may not be able to treat water effectively Side stream systems may be able to use waste heat to raise water temperature UV systems are affected by water quality High TSS may shadow the UV light Erode the quartz sleeve of UV lamps Some systems increase the dose based on UVT Filters may increase DP and backfushing
Chemical / Product / tanker installation Submerged Ballast pumps and ballast discharge BWT room on deck for chemical tankers Equipment installed in a hazardous area must be explosion proof Ballast water from a tank within the hazardous area cannot pass back into a non-hazardous area Ballast water piping serving tanks in non-hazardous area may be used to fill the ballast tanks in hazardous area, provided that an appropriate means of isolation is provided.

Port State Control Inspections PSC Inspections Initial inspection Detail Inspection Indicative analysis Detailed analysis Valid IBWM certificate Approved BWMP BW Record book correctly completed Nominated officer
Port State Control Inspections PSC Inspections Initial inspection Detail Inspection Indicative analysis Detailed analysis BWTS condition and operated correctly False entries in BW Record Book ( not consist with BWMS data logger) Deviation from approved BWMP Crew not familiar with procedures relating to BW management Intake of ballast water from an area where hazardous condition declared Ship presents threat of harm to environment, human health, property or resources which constitute a clear ground for sampling
Port State Control Inspections PSC Inspections Initial inspection Detail Inspection Indicative analysis Detailed analysis Check operational and performance indicators Rapid sampling to identify ballast discharge meet D-2 standards
Port State Control Inspections PSC Inspections Initial inspection Detail Inspection Indicative analysis Detailed analysis Detail analysis of sample to ascertain any non-compliance
Port State Control what do we know? PSC inspection will follow the normal format i.e.:- An initial inspection A detailed inspection if there are clear grounds the vessel is not compliant with the Convention. Sampling Detail analysis What does non-compliance mean? Deficiency notice could be issued Ballast discharge could be stopped Detention Targeting for future inspections in subsequent ports
How to mitigate potential problems? 1 2 3 4 5 6 7 8 Understand your obligations under the convention Ensure crew is adequately trained in BWM operations Manage ballast and sediments in accordance with the Convention Follow the procedures in the approved BWMP Maintain the Ballast Water Record Book up to date Ensure required surveys are carried out within permitted range dates Operate and maintain equipment in accordance with manufacturer s instructions Monitor the treatment system performance
