The BWMC option of exemption

  • Exemptions for vessels operating

exclusively in a limited area

  • Regional short sea shipping
  • Ferry lines “A to B and back”
  • >2 port Ro-Ro/PAX
  • Feeder traffic
  • North Sea OSV
  • Wind farm vessels

BWMC: A-4 Exemption from D-2; valid 5 years

  • Ship operates between specified ports or

locations SPECIFIED LOCATIONS

  • Three types of RA, but must show low

risk for invasive species (in SRA species-to-species) RISK ASSESSMENT

  • Vessel may only discharge untreated BW

from/to the specified ports or location NO MIXING

The SRA procedure

  • In summary, the key elements of the

SRA concept are: 1. exemption procedure under the Convention regulation A-4; 2. based on a risk assessment related to identified target species; 3. defines an area that exhibits acceptable risk regarding transfer with ballast water of target species compared to the estimates of natural dispersal

  • ver time (connectivity); and

4. exemptions can be granted to vessels operating exclusively in this area and not mixing water and sediments if travelling

  • utside the area.

29/11/16 9 States identify possible SRA and target species Risk assessment conducted with SRA objective Extent of SRA is agreed among SRA states based on risk assessment Vessels apply for exemption in

  • ne state with

cc to other SRA states MEPC is informed of SRA and vessels granted exemption OSPAR HELCOM TG Ballast

The Same Risk Area Scientific basis

Target species characteristics e.g. the occurrence and duration of egg or larval stages, foraging and mobility, spawning characteristics, settling rate, mortality, and behavioural aspects Hydrodynamic, environmental and meteorological features e.g. the historic and seasonal pattern of currents, tidal regime, salinities, temperature, and wind patterns Habitat occurrence and preference, e.g. the occurrence of soft or hard bottom environs, corals, river banks, littoral and high energy zones

Natural dispersal and “connectivity”

29/11/16 10

  • Dispersal distances
  • Pelagic Life Duration
  • Hydrodynamics/flow regimes
  • Biophysical modeling
  • (Genetic metrics)
  • Agent-based modeling

29/11/16 11

  • Availability of key data on target species
  • History of hydrodynamic base data

(10 y 95% fractile, annual average, seasonal extreme?)

  • Run time for dispersal

(5, 10, >10 years?)

The Same Risk Area tool

Agent based model:

Connectivity model: Larvae traits; Kattegat- Skagerrak (N. Europe) Pelagic larvae; Great Barrier Reef (Australia) Coral reef fish, islands (Indo- Pacific) Used in assessing marine parks network

Same Risk Area – Risk assessment

Risk Assessment steps (G7 species-specific)

  • Identify area, i.e. ports and locations
  • Target species and characteristics
  • Identify hydrodynamic and environmental conditions
  • Assess natural dispersal in respect of species biology and

hydrodynamic regime (connectivity)

  • Reduce area to include only ports with connectivity – the SRA
  • Compare natural dispersal to ballast water mediated transfer
  • In the final area include only ports and locations with

acceptable low risk

Conclusions

  • The SRA is aimed at providing a risk-based approach to area

based exemptions founded on G7

  • The key new component of SRA is the assessment of the

natural dispersal of target species by way of hydrography or

  • ther natural mechanisms
  • The SRA can be a valuable tool for reducing complexity, costs

and administrative burden in short sea shipping
