1. Ship Based Waste Management Principle objective for; Integrated Bilge Treatment Systems (IBTS) Minimize the amount of oily bilge generated in machinery spaces by treating the leaked water and oil separately. Also provides for an integrated means to process the oily bilge water and oil residue (sludge). i. Engine room bilge systems ii. Sludge treatment systems
1. Ship Based Waste Management • Engine room bilge systems • Separate oil from bilge water, pumping clean bilge water overboard and allowing for the storage and disposal of the waste oil. • Bilge treatment systems have been used on board for over 25 years but they were not necessarily designed and fitted for the purpose • Equipment often incapable of being able to separate the oil/water mixture due to contamination
1. Ship Based Waste Management • Engine room bilge systems • Previously: IMO resolution MEPC.60(33) • - Bilge water separators to be tested with a mixture of oil and water • Since January 1, 2005: IMO resolution MEPC.107(49) • - Bilge water separators to be tested also with a stable emulsion • - Oil-in-water monitor to include a recording function for date, time, alarm and operating status. The recording of the operation to be stored for 18 months • - INTERTANKO believe there is still room for improvements in design, capacities and procedures for operation • - According to recent reviews, one could conclude that overall system designs have never been formally analysed, from the bottom up
1. Ship Based Waste Management • Engine room bilge systems • Oily Water Separator capacity should be addressed: • Current designs • - Aframax, only 2m3/hr • - Handymax tanker, only 1m3/hr • Minimum design criteria • - Aframax, min 5m3/hr • - Suezmax/VLCC, min 10m3/hr
1. Ship Based Waste Management • ii. Sludge treatment systems • Designed to remove as much water as possible and recover the useful oil for further use • - Common practice for fuel and lube oil sludges to be combined • - Connection pipes only to incinerator or shore side reception facility – no further drain pipe allowed • Option to: • - Reduce quantity of waste necessary for shore delivery • - Improve combustibility of sludge in incinerator
1. Ship Based Waste Management • ii. Sludge treatment systems • Options • 1. Reduce amount of water entering the sludge tank • a. Reduce amount of generated water from the system in the first instance • b. Add a second sludge tank to allow further time for water/oil separation • 2. Increase sludge tank capacity
1. Ship Based Waste Management • ii. Sludge treatment systems • Options cntd.: • - Tank volume: 2 days storage at a discharge interval of 2 hours • - Manhole for inspection and cleaning • - Fitted with a sounding pipe • - Tank floor with a slope of minimum 15° • - The sludge outlet pump connection positioned at the lowest part of the tank • - High level alarm switch, connected to the sludge pump • - Heating coil to keep the sludge warm and fluid while being pumped out • - Tank ventilation must follow the classification rules for evacuation of gases • - There should be a ventilation pipe to fresh air • - The ventilation pipe should be straight. Any bends must be gradual • - The ventilation pipe kept above the tank top • - A sludge tank with partition walls must have ventilation pipes in all compartments

2. Shore Based Waste Management Reception Facilities IMO - MEPC endorsed IMO Action Plan on Reception facilities which will be discussed and acted upon at FSI 15 in 2007 - Industry input essential Europe Union - EU Directive revision (EMSA) - Fees system 2006 - Technical amendments 2007 Wild card politics - Probo Koala - Basel Convention Responsibility Adequacy Shore standards
Waste Management Closing remarks Industry initiatives taking lead: - Industry guidelines, code of conduct - Industry Forum’s and action plan Reliance on outside support: - Equipment manufacturers, PSC - Terminal and port operators, charterers Responsible legislators: - Understanding industry needs and input - Taking the issue at source, understanding commercial realities - Not going for politically motivated solutions – eyes wide open!
