2012 Ocean Ranger Guidebook 3-7-12 Job Aid Item: 7.5.a Text: Check lifeboat / security / tender vessel engineering systems are oil or grease leak / drip free (40 CFR 110.3) Background: Small vessels used by the cruise ship in regular or emergency operations are potential sources of oil. What to check for: Visually check decks under stowed tenders and boats for signs of oil spills or oil stains. Include a visual inspection for greased gobs / drops on decks / equipment. Winch equipment containment should be oil free. Some vessels have “outrigger davits” they are hydraulically operated. Check hose connector oil sweating / leaks and containment areas. Also steel rope should be checked for grease gobs. Job Aid Item: 7.5.b Text: Check lifeboat / security / tender vessel bilges are clean (40 CFR 110.3) Background: Small vessels used by the cruise ship in regular or emergency operations are potential sources of oil. What to check for: Visually check when available the bilges of vessels operated by the cruise ship. Should be clean and well maintained. Job Aid Item: 7.5.c Text: Check oil and grease from topside equipment (winches motors etc.) (EPA VGP 2.2.1) Background: Equipment such as winches and motors used to lower and raise lifeboats and tenders are a potential source or oil or grease into water, either directly running off or during cleaning activities. What to check for: Visually check for oil spills on decks near machinery. If drip pans are available, check that there are procedures for draining and cleaning the pans. Citation: EVP VGP 2.2.1 Deck Washdown and Runoff and Above Water Line Hull Cleaning 216
2012 Ocean Ranger Guidebook 3-7-12 Vessel owner/operators must minimize the introduction of on-deck debris, garbage, residue and spill into deck washdown and runoff discharges. When required by their class societies (e.g., oil tankers), their flag Administrations, or the U.S. Coast Guard, vessels must be fitted with and use perimeter spill rails and scuppers to collect the runoff for treatment. Where feasible, machinery on deck must have coamings or drip pans to collect any oily water from machinery and prevent spills. The drip pans must be drained to a waste container for proper disposal and/or periodically wiped and cleaned. The presence of floating solids, visible foam, halogenated phenol compounds, and dispersants, or surfactants in deck washdowns must be minimized. Vessel operators must minimize deck washdowns while in port. Subsection 6: Oil to Sea Interface (40 CFR 110.3) Job Aid Item: 7.6.a Text: Check oil lubricated stern tubes, bow and stern thruster seals, fin-stabilizers, steering gear, Azipods etc. (EPA VGP 2.2.9) Background: Any oil to sea interface is a potential source of oil leaking to seawater. Ocean rangers have reported a number of seal and azipod leaks. These leaks can start out at a small volume and increase over time. What to check for: Check header tank levels under several operation conditions, seas, port, maneuvering etc. Check records of fill up volumes and frequency. Check for evidence of seawater intrusion into these oil to sea interfaces, such as draining of seawater from systems. Citation: 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. Job Aid Item: 7.6.b Text: Check lube oil consumption oil records / type of oil used. (33 CFR 151.25) What to check for: record of lub oil consumption and the type of lub oil used. In order to detect “consumption trends” check the records back to early in the season. Sudden increase of lub oil in for example sterntube may indicate an oil leak. Some vessels keep also records of the oil drum store, such records are extremely helpful to find out which oils are used on board. 217
