When ships discharge their bilge water the maximum level of hydrocarbons in the water is regulated by various Environmental Protection Agencies, for example there is a limit of 15ppm enforced by the IMO (International Maritime Organisation) in all international waters.  Companies breaching these limits are liable to significant fines.

Further regulations have been introduced to control the use of bunker fuels. The Marine Environment Protection Committee (MEPC) of the IMO has approved proposed amendments to the MARPOL Annex VI regulations to reduce harmful emissions from ships.

Bilge Water

The water that gathers in the bilge of a ship is collected from a number of sources, usually rough seas, rain and leaks or spillages. This water can contain oil and grease, detergents, solvents, chemicals and particles.

It must eventually be pumped out to prevent the bilge from becoming too full and it is important to understand how much oil and grease is being discharged also.

The oil in water analysers from Advanced Sensors provide a highly accurate and reliable solution.  With automatic ultrasonic cleaning, these analysers stay clean regardless of how oily the water becomes and are not impacted by the presence of particles in the water.


Engine and Bearings Corrosion

Water in the lubrication system can lead to corrosive wear of the overlayer and lead to mechanical damage to crosshead bearings. The costs to fix such damages are high: parts, material and labour are one part of the equation the other is the crippling effect of marine vessel down time. Advanced Sensors Water Cut/Water in oil analysers measure the content of water in lubricates to maintain uptime of critical components.

Exhaust Gas Cleaning

The IMO Annex VI sulfur regulation calls for a 0.1% sulfur limit in Emission Control Areas (ECA) a worldwide limit of 0.5% by 2020.

One of the key effects of the regulation has been a rise in the use of Exhaust Gas Cleaning Systems.  Use of an exhaust gas cleaning system enables shipping companies to continue using heavy fuel oils however, they do need to prove the cleaning systems have been effective.

By focusing on PAHs (Polycyclic Aromatic Hydrocarbons), a serious environmental contaminant, Advanced Sensors EX and SA 500 Deep UV analyser can provide continuous information regarding the cleanliness of the water, allowing the ship operator to prevent any harmful discharge.

A Certified Solution

A number of Advanced Sensors analysers are approved for use under Merchant Shipping Equipment Regulation, the American Bureau of Shipping, the USCG and IMO Regulation MPEC 107.
