Alfa Laval Nordic AB
Global marine supplier Alfa Laval now offers a set of sustainable solutions designed to help ship owners and operators comply with current and pending environmental regulations. Grouped under the conceptual name “Pure thinking”, the products will provide security as existing legislation is tightened, as well as compliance with new laws such as those that will regulate ballast water treatment. While most of the solutions can be retrofitted, incorporating them at the newbuilding stage will contribute to gaining DNV’s Clean Design class notation for the vessel under construction.
PureBallast – a way to future-proof ship operation
Shipyards and ship owners now purchasing, installing and commissioning ballast water treatment systems will be the ones best prepared for 2016, when the IMO Ballast Water Convention mandates that all ships in service must use ballast water treatment.
Now in its second generation, Alfa Laval’s PureBallast is an easy-to-use ballast water treatment system with full type approval and a proven track record at sea. Offering green operation without chemicals, toxic residue or other safety hazards, it neutralizes the microscopic organisms that are generally taken in with ballast water. This eliminates the threat of biological invasions when water from one part of the world is released in another.
Alfa Laval is a market-leading provider of solutions which, integrated into the designs of virtually all ship types, help ship owners and operators comply with increasingly stringent local and global environmental regulations. Like other Alfa Laval solutions, PureBallast is the result of continuous product development and extensive experience gained from cooperation with shipyards throughout the world.
PureBilge – first with DNV 5 ppm type approval
For bilge water, the DNV Clean Design class notation stipulates a maximum of 5 ppm of oil remaining in the water after treatment, prior to pumping overboard. Although MARPOL regulations still stipulate 15 ppm, future legislation is expected to reduce the limit to 5 ppm. In 2011, DNV introduced a 5 ppm type approval process for marine bilge water separators. The first to be certified was PureBilge from Alfa Laval.
PureBilge is the only system on the market that provides cleaning performance in real life conditions of 0-5 ppm oil content in the water without chemicals, adsorption filter or membranes. This performance is unaffected by sea heave, oil shocks or high solids loading, and no backflushing is required.
The PureBilge system offers the full automation and remote control that will be required by the unmanned engine rooms of the future and is supplied with the fully integrated tamperproof BlueBox Bilge Data Recorder. In combination with PureBilge’s certified performance, the result is assured compliance with current and future legislation.
