Ship Owners Worry as Ports Ban Economical Option ‘Scrubbers’

  • Many ports are banning one of the cheapest options for meeting new environmental shipping rules imposed by IMO.
  • The fuel cleaning system pumps waste water into the sea and this is the reason sighted for the ban.
  • Cruise and shipping firms might have to pay for new equipment and extra types of fuel and adjust their routes.
  • Companies invested in open loop scrubbers cannot use them in those banned ports and they also fear if IMO rules could change to ban open loop scrubbers altogether.
  • The world’s...

Open Loop Scrubbers Viable for 80-90% of Global Shipping

  • Yara Marine sees 80-90% open loop scrubbers feasible, though a growing number of countries and regions around the world are introducing bans on the same.
  • Some studies shown no real environmental impact by open loop bans.
  • Few maintain that the effects of wash water have yet to be assessed or may even be harmful, or for reasons other than environmental concern.
  • Open loop scrubbers, do not perform effectively in water with low alkalinity, so systems supplying alkali in a closed loop are required.

The Scrubbers Story – Inside Out

In preparation for the upcoming global sulphur cap, set to enter into force in January 2020, many owners opted to install exhaust gas cleaning systems (EGCS) on their vessels to attain compliance. But still much ambiguity remains regarding the scrubber system. To thoroughly understand the dynamics of the scrubbers system, the World Maritime News Erna Penjic took an interview of Erik Haveman, Sales Director, Exhaust Gas Cleaning, Alfa Laval.

Here’s an excerpt from that interview which tells the...

Stop the Hype on Open-loop Scrubbers for Sake of Human Health – EGCSA

  • The hype around open loop exhaust gas cleaning systems wash water discharge dilutes the focus on human health and the environment.
  • Some governments and authorities decide to ban open-loop scrubbers, saying the discharging wash water from open-loop scrubbers into their territorial waters is not acceptable.
  • During the recent sixth PPR sub-committee meeting again the use of EGCS was endorsed as an approved option for complying with the 2020 0.5% sulphur cap.
  • Vessels fitted with EGCS can...

Scrubber Users Fight European Wash Water Proposals

  • IMO’s MEPC has stressed on strict discharge criteria for open-loop scrubbers as a part of European Commission proposal to harmonise regulations governing the sulphur abatement technology.
  • The committee stressed the importance of scrubbers for sulphur compliance and has agreed to map key areas for port discharges.
  • CSA 2020 has rejected the committee’s proposal citing no credible evidence and incomplete preliminary studies.

According to an article by mpropulsion, Stricter discharge criteria for...

Japan Supports Use of Open-loop Scrubbers

  • Japan concludes no scientific justification to ban open-loop scrubbers.
  • California and Connecticut in the US, Fujairah, Singapore, China have introduced regulations and jurisdictions to prevent discharge from open-loop scrubbers.
  • The issue raised is that open-loop scrubbers do not address environmental issues as they simply take sulfur out of the air and put it into the ocean.
  • Japan concluded that the discharge water with chemical substances such as SOx, PAHs and heavy metals cannot cause...

[Answer] How To Know If the Water Alkalinity Is Suitable for Open-type Scrubbers?

Water Alkalinity is the chief reason why scrubbers are employed by shipowners. But how do you know the extent of this alkalinity? While regular checking and testing of alkalinity isn’t possible and also most waters around the world have scrubber friendly alkalinity yet some measures can be taken to the suitability of alkalinity in case of open loop scrubbers.

Here’s how to do it. This ensures Water-Scrubber Compatibility.

The Alkalinity Check

The alkalinity of the sea and harbors open to the sea...
