Oil discharge monitoring equipment (ODME) is based on a measurement of oil content in the ballast and slop water, to measure conformance with regulations. [1] The apparatus is equipped with a GPS, data recording functionality, an oil content meter and a flow meter. [2]
[1] [3] To prevent this, fluorescent tubes are connected to the power line through a ballast. The ballast adds positive impedance (AC resistance) to the circuit to counteract the negative resistance of the tube, limiting the current. [1] Several American magnetic ballasts for fluorescent lamps. The top is a rapid start series autoregulator ...
Temperatures in this area are much lower due to the cooling of the sea. If this extremely cathodic region is placed close to an anodic source (e.g. a corroding ballast pipe), cathodic blistering may occur especially where the epoxy coating is relatively new. Mud retained in ballast water can lead to microbial corrosion. [4]

Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...

[citation needed] With MARPOL tankers, it is not allowed to use ballast tanks as cargo tanks. This has reduced operational spillage drastically. The downside is designs based on MARPOL spill more oil when damaged than a preMARPOL tankers. This is due to several factors: as ballast tanks could not be used as cargo tanks anymore, cargo space was ...
This type of ballast is common in 220–240V countries (And in North America, up to 30W lamps). Ballasts are rated for the size of lamp and power frequency. In North America, the AC voltage is insufficient to start long fluorescent lamps, so the ballast is often a step-up autotransformer with substantial leakage inductance (to limit current flow).
