Unit 1 Flashcards
What is the definition of Oil?
Oil means petroleum in any form, including crude oil, fuel oil, sludge, oil refuse, and refined products (except for certain petrochemicals under Annex II of the Convention). It includes substances listed in the regulation.
What is an Oily Mixture?
Oily mixture means a mixture with any oil content.
What does Oil Fuel refer to?
Oil fuel means any oil used as fuel for the propulsion and auxiliary machinery of the ship carrying it.
What is an Oil Tanker?
An oil tanker is a ship constructed or adapted primarily to carry oil in bulk in its cargo spaces. This includes combination carriers, NLS tankers, and gas carriers when carrying a cargo or part cargo of oil in bulk.
What is a Combination Carrier?
A combination carrier is a ship designed to carry either oil or solid cargoes in bulk.
What does “Nearest Land” mean?
“From the nearest land” refers to the baseline from which the territorial sea is established, except for a specific area off the northeastern coast of Australia as per the Convention.
What is a Special Area in maritime terms?
A special area is a sea area requiring special mandatory methods for preventing sea pollution by oil due to its oceanographical and ecological conditions and the character of its traffic.
How is the Instantaneous Rate of Discharge of Oil Content calculated?
It is the rate of discharge of oil in liters per hour at any instant divided by the ship’s speed in knots at that same instant.
What is a Wing Tank?
A wing tank is any tank adjacent to the side shell plating.
What is a Centre Tank?
A center tank is any tank inboard of a longitudinal bulkhead.
What is a Slop Tank used for?
A slop tank is a tank designated for collecting tank drainings, tank washings, and other oily mixtures.
What does Clean Ballast mean?
Clean ballast is ballast in a tank that, since oil was last carried, has been cleaned so that effluent discharged from a stationary ship would not produce visible oil traces or cause sludge/emulsion on the water surface or shorelines.
What is Segregated Ballast?
Segregated ballast is ballast water in a tank completely separated from the cargo oil and oil fuel system, permanently allocated to carry ballast or cargoes other than oil or noxious liquid substances.
What is a Particularly Sensitive Area (PSSA)?
A PSSA is an area needing special protection by IMO due to its ecological, socio-economic, or scientific significance and vulnerability to maritime activities.
What is a Vessel Response Plan (VRP)?
A VRP is required by OPA-90 and MARPOL 73/78 for vessels carrying certain quantities of chemicals and/or refined petroleum products, and it must be approved by the U.S. Coast Guard.
What is the purpose of a Bilge Water Holding Tank?
A tank that collects oily bilge water before it is discharged, transferred, or disposed of.
What is an Oily Water Separator (OWS)?
A shipboard oily water separator (OWS) is designed to separate oil and contaminants that could be harmful to the oceans, as regulated by the International Maritime Organization (IMO).
What type of certificate is issued after a survey of an oil tanker or ship according to MARPOL Annex I?
An International Oil Pollution Prevention (IOPP) Certificate.
Which ships are subject to an initial survey under MARPOL Annex I?
Every oil tanker of 150 gross tonnage and above, and every other ship of 400 gross tonnage and above.
What is the purpose of the initial survey for ships under MARPOL Annex I?
To ensure that the ship’s structure, equipment, systems, fittings, arrangements, and material fully comply with the applicable requirements of MARPOL Annex I before it is put into service or issued an IOPP certificate.
How often must a renewal survey be conducted according to MARPOL Annex I?
At intervals not exceeding 5 years, except under certain conditions specified in regulations 10.2.2, 10.5, 10.6, or 10.7.
When must an intermediate survey be conducted under MARPOL Annex I?
Within 3 months before or after the second or third anniversary date of the IOPP Certificate, taking the place of one of the annual surveys.
What is the purpose of an annual survey under MARPOL Annex I?
To ensure that the structure, equipment, systems, fittings, arrangements, and material remain satisfactory for the service and are maintained according to regulations.
When is an additional survey required under MARPOL Annex I?
After repairs due to investigations or whenever any important repairs or renewals are made.
Under what conditions can oil or oily mixtures be discharged from the cargo area of an oil tanker outside special areas, according to MARPOL Annex I?
- The tanker is not within a special area.
- It is more than 50 nautical miles from the nearest land.
- The tanker is proceeding en route.
- The instantaneous discharge rate does not exceed 30 liters per nautical mile.
- The total quantity discharged does not exceed 1/30,000 of the last cargo.
- The tanker has an operational ODMCS and slop tank arrangement.
What are the conditions for discharging oil or oily mixtures from machinery space bilges outside special areas?
- The ship is proceeding en route.
- The oily mixture is processed through oil filtering equipment.
- The oil content of the effluent without dilution does not exceed 15 ppm.
- The oily mixture does not originate from cargo pump-room bilges on oil tankers.
- The oily mixture, in the case of oil tankers, is not mixed with oil cargo residues.
What restrictions apply to discharging oil or oily mixtures in special areas according to MARPOL Annex I?
The discharge is prohibited unless:
- The ship is proceeding en route.
- The oily mixture is processed through oil filtering equipment.
- The oil content without dilution does not exceed 15 ppm.
- The oily mixture does not originate from cargo pump-room bilges on oil tankers.
- The mixture is not mixed with oil cargo residues.
What conditions exempt a ship from MARPOL Annex I provisions when discharging clean or segregated ballast?
- The ship is an oil tanker delivered before 1 June 1982, exclusively on voyages of 72 hours or less, within 50 nautical miles from the nearest land, and between ports or terminals within a State Party.
- The ship is a special craft, such as a hydrofoil, air-cushion vehicle, near-surface craft, or submarine.
Under what conditions can oily mixtures from machinery spaces be discharged without using an OWS?
Only in an emergency to save life or the vessel, provided there is an alternate slop tank to store the mixture.
What must be done with residues that cannot be discharged into the sea according to MARPOL Annex I?
They must be retained on board or discharged to reception facilities.
What are the Special Areas defined under MARPOL Annex I?
- Mediterranean Sea area
- Baltic Sea area
- Black Sea area
- The Gulf
- Gulf of Aden
- Red Sea Area
- Antarctic area
- North West Europe
- Oman & Arabian Sea
- Southern South Africa
What equipment must oil tankers of 150 GRT and above be fitted with under MARPOL Annex I?
An Oil Discharge Monitoring and Control System (ODMCS).
