2012 Ocean Ranger Guidebook 3-7-12 Background: OWS oil content metering should be functional with the set parameters (calibrations). What to check for: If multiple oil content meters installed the meter should give similar reading over the same sample flow. Calibration records should include the oil content meter checks and findings including the calibration actions and ranges. Recording s monitoring results of the readings? Job Aid Item: 7.2.d Text: Ensure sample analyzed by OWS meter is OWS output (trace sample line for presence of unacceptable clean water connection) (33 CFR 155.370(a)) (33 CFR 151.10) Background: OWS treated flow should be the flow which is used for “compliance” measured oil content. What to check for: The treated flow outlet from OWS to the discharge is sampled (representative) by the OWS oil content meter. Piping in place to the meter. Alarm monitor readings during operation of the OWS? Job Aid Item: 7.2.e Text: Check for oil dispersants use in oil tanks or lubrication systems (40 CFR 110.4 & EPA VGP 2.2.9) Background: Oil dispersants could remove a sheen, when oil is still being discharged to waters. Some emulsifiers could be used to cause oil or grease to sink instead of float, which reduces the likelihood of an oil loss being detected. It also creates more difficult conditions for clean-up. What to check for: Check for dispersants added to oil tanks or lubrication systems such as shaft seals. Check when tanks are filled. Check for possible “chemical” dosing systems. Not to be confused with the cleaning system of the OWS itself. Citations: 40 CFR 110.4 Dispersants. Addition of dispersants or emulsifiers to oil to be discharged that would circumvent the provisions of this part is prohibited. EPA VGP 2.2.9 Controllable Pitch Propeller and Thruster Hydraulic Fluid and other Oil to Sea Interfaces including Lubrication Discharges from Paddle Wheel Propulsion, Stern Tubes, Thruster Bearings, Stabilizers, Rudder Bearings, Azimuth Thrusters, Propulsion Pod Lubrication, and Wire Rope and Mechanical Equipment Subject to Immersion. The protective seals on controllable pitch propellers, azimuth thrusters, propulsion pods, rudder bearings, or any other oil to sea interfaces must be maintained in good operating order to minimize the leaking of hydraulic oil or other oils. The vessel owner/operator must not discharge oil in quantities that may be harmful as defined in 40 CFR Part 110 from any oil to sea interface. If possible, maintenance activities on controllable pitch propellers, thrusters and other oil-to-sea interfaces should be conducted when a vessel is in drydock. Minimize maintenance activities on stern tube seals when a vessel is outside of drydock. If maintenance or emergency repair must occur on stern tubes or other oil-to sea interfaces which have a potential to release oil in quantities that may be harmful as defined in 40 CFR Part 110, appropriate spill response resources (e.g. oil booms) must be used to contain any oil leakage. Operators of the vessel must have ready access to any spill response resources to clean any potential oil spills. After applying lubrication to wire rope and mechanical equipment subject to immersion, wire ropes and other equipment must be thoroughly wiped down to remove excess lubricant. Owner/operators should use an environmentally preferable lubricant, including vegetable oil, synthetic ester, or polyalkylene glycol as a base for these applications when feasible. Use of an environmentally preferable lubricant does not authorize the discharge of any lubricant in a quantity that may be harmful as defined in 40 CFR Part 110. 210
2012 Ocean Ranger Guidebook 3-7-12 Job Aid Item: 7.2.f Text: Observe if there are obvious electrical bypasses, jumpers, extra switches on unit or meter control panel. (33 CFR 155.370(a)) (33 CFR 151.10) What to check for: Check for any unusual connections on or around the meter control panel that could bypass the system or provide false or inaccurate readings. Citations: 33 CFR 155.370 Oily mixture (bilge slops)/fuel oil tank ballast water discharges on oceangoing ships of 10,000 gross tons and above and oceangoing ships of 400 gross tons and above that carry ballast water in their fuel oil tanks. (a) No person may operate an oceangoing ship of 10,000 gross tons and above, or any oceangoing ship of 400 gross tons and above, that carries ballast water in its fuel oil tanks, unless it has— (1) Approved 15 ppm oily-water separating equipment for the processing of oily mixtures from bilges or fuel oil tank ballast; (2) A bilge alarm; and (3) A means for automatically stopping any discharge of oily mixture when the oil content in the effluent exceeds 15 ppm. (4) For equipment installed after 2004 to be approved under paragraph (a) of this section, it must meet current standards in 46 CFR part 162, subpart 162.050 by the date set forth in paragraphs (a)(4)(i) and (a)(4)(ii) of this section, unless the equipment is installed on a ship constructed before 2005 and it would be unreasonable or impracticable to meet those current standards. (i) A ship entering international service for the first time since 2004, must comply with the requirements of paragraph (a)(4) of this section by the date of its initial survey prior to receiving its International Oil Pollution Prevention (IOPP) certificate. (ii) Any ship, other than a ship described in paragraph (a)(4)(i) of this section, must comply with the requirements of paragraph (4) of this section by the date of the ship’s first drydock after October 13, 2009. Job Aid Item: 7.2.g Text: Visually observe has automatic re-circulate (3 way valve) or shuts down when > 15 ppm. Observe proper operation of valve in use. (33 CFR 155.370 a(3)) What to check for: Understand the three way valve pipe connections and re-circulation system / tank system. How is the three way valve activation done? How is the valve operated? Are safeties in place when air pressure / electric failure occurs to the valve (Normally closed?). Are valve activation controls bypassed or feed by outside (non OWS) source? Citations: See 7.2.f above. Job Aid Item: 7.2.h Text: Observe for proper operation of system back flush or oil purge cycle if in use.(40 CFR 110.3) Background: OWS functional check. In order to make sure that the oily wastes are discharged correctly an OWS system must be used and operable. These items are most likely to be witnessed when the OWS is operated. What to check for: When back flush is performed, monitor check system parameters controls. Where is the back flush routed too? Are the operational mode displayed? Is the purge cycle working? Citations: See general OWS information. Job Aid Item: 7.2.i Text: Visually observe processed water for gross contamination (sheen or visible oil) (40 CFR 110.3) Background: Gross contamination is infact malfunctioning OWS. The OWS discharge is on most large vessels under the water line and may be hard to witness sheens (if any) What to check for: During operation of OWS a visual check over board should be made to see any sheens. However the oil content meter should provide in such case alarms. 211
