What is Copenhagen Design Support Centre (CDSC)???
  • Design Support and Plan Approval for the Nordic
    countries
  • One stop shop for both advise and traditional
    Plan Approval
  • All disciplines represented
  • Specialises in
  • Off-shore support vessels
  • RO/PAX vessels
  • Chemical carriers
  • MODU certification
  • Augmented by our colleagues in Hamburg and
    Rotterdam
  • Further back-up by the rest of the Lloyds
    Register Group around the globe

4
What is NEA Statutory Advisory Team
  • A group of statutory specialists within CDSC
  • Skills in the following areas
  • Stability
  • Fire Safety
  • Life Saving Arrangements
  • SOLAS Chapter V
  • MARPOL
  • Other MEPC issues
  • EU regulations
  • Advising clients and Lloyds Register Group field
    surveyors on statutory issues

    invitation of the DMA)

5
A politically incorrect formula
  • Cp Perceived cost of pollution
  • Mas Miles of affected shoreline
  • Mvs Number of voters on affected shoreline
  • Ndb Number of dead birds
  • J Number of journalists present
  • Cf Country factor
  • My message this is the decade of environmental
    regulation!

6
Introduction Things to remember
  • Statutory rules and regulations are made by
  • Civil servants
  • Academia
  • Industry representatives (and that means your
    representatives!)
  • Statutory rules and regulations are promulgated
    by politicians
  • Statutory rules and regulations are put into
    force by flag administrations
  • Statutory rules and regulations are enforced by
    Recognised Organisations (RO)
  • Statutory rules and regulations are to be adhered
    to by ship-owners, shipyards, designers,
    equipment manufactures etc.
  • The only one with responsibility for the ship is
    the shipowner!!!!!

7
One more thing
  • Flag is always right
  • Class as an RO are acting on behalf of the
    flag state administration in order help the
    shipowner to comply with statutory regulations.

8
Part IKey Dates for Statutory legislation (1)
  • Enter into force date for a convention
  • 12 month after the ratification date on which day
    the convention has been ratified sufficient
    number of stats with enough percentage of Gross

    within an average of five years after adoption.
  • Enter into force date for a resolution containing
    amendments
  • Final implementation date according to tacit
    acceptance procedure.

    date

9
Key Dates (2)for Statutory legislation
  • Application key dates for a specific
    amendments/regulations

Part VIIShip Recycling and Green Passport
  • IMO Guidelines on Ship Recycling, A.952(23)
  • adopted on 5 December 2003
  • Green Passport is a document that contains an
    inventory of materials onboard a ship which may
    be hazardous to human health or to the
    environmental.
  • Certificate (Document of Compliance) Inventory
  • to be maintained throughout the ships
    operational life. At the end of a ships life,
    the Green Passport can be used to assist safer
    and more environmentally sound dismantling of the
    ship.
  • Life cycle Design Construction, through-life
    operation and end of life.

35
Ship Recycling and Green Passport (2)Benefits to
the Owners

  • LR do not compile Green Passports
  • For new ships, the yard should prepare the
    hazardous materials inventory and for existing
    ships, Owners/crews will need to compile
    inventory.
  • LR supply a Guide to the Green Passport, Rev.
    July 2006 and supply an electronic template to
    assist preparation
  • World-wide service net with well trained
    surveyors

40
Ship Recycling and Green Passport (7)Completing
the Inventory (2)
  • In case where testing would be required in order
    to establish whether a hazard exists, the owner
    have the option not to test, but to declare the
    material a probable or presumed hazard.
  • Proper safety and environmental hazard management
    systems must exist for all noted probable,
    possible, presumed or actual hazards.
  • These systems are not part of the Green Passport
    since they are covered by the ISM code. However,
    the Green Passport will be available to ISM
    auditors and may be used as a source of reference
    during the audit.

    equipment for machinery spaces bilge by
    MEPC.107(49). But the treatment process of oily
    bilge water with the improved equipment and the
    engineers load is basically unchanged and the
    amount of oily bilge water generated in ships has
    not been reduced.
  • Approved the concept of an Integrated Bilge Water
    Treatment Systems (IBTS)
  • Incorporates the means to reduce the amount of
    oily bilge water and process the oily bilge water
    and oil residue (sludge) in a holistic manner.

Integrated Bilge Water Treatment System
(2)Concept
  • IBTS is a system to minimize the amount of the
    oily bilge water generated in machinery spaces by
    means to treat the leaked water and oil
    separately. It is also provides integrated means
    to process the oily bilge water and oil residue
    (sludge).
  • Outline of IBTS
  • Collection of drains
  • Pre-treatment of oily bilge water
  • Discharge of oily bilge water
  • Discharge of clean drains
  • Treatment of oil residue (sludge)

(4)Additional Installation of IBTS (1)
  • Drainage System
  • Drip trays or coamings for equipment used for oil
    such as diesel engines, burners, pumps, heaters,
    filters and tanks to keep spillage of oil.
  • Drip trays or coamings for equipment used for
    water such as pumps, heaters, coolers, filters,
    tanks, condensers and boilers to keep spillage of
    water.
  • Pre-treatment unit for oil separation
  • Bilge primary tank with construction of cascade,
    which is able to separate oil from oily bilge
    water by gravity with drainage facilities of the
    oil on the top as primary separation of oily
    bilge water.

(5)Additional Installation of IBTS (2)
  • Storage tanks
  • Clean drain tank Tank for the retention of clear
    drains.
  • Bilge water holding tank Tank for the retention
    of oily bilge water.
  • Waste oil tank tank for preparation of oil
    residue (sludge) for incineration.
  • Discharge arrangement of clean drains
  • The discharge arrangement of clean drains to
    overboard should be independent from the system
    for oily bilge water.
  • Exclusive pump for the oil filtering equipment
  • It is preferable to be provided with an excusive
    pump to transfer the pre-treated bilge water from
    bilge water holding tank to the oil filtering
    equipment so as not to mix the pre-treated bilge
    water and untreated oil bilge water.
  • Heating Arrangement
  • To the bilge primary tank to facilitate
    separation of oil
  • To the waste oil tank to vaporize water and
    facilitate incineration.

One last thing
  • The shipowner is the one who are
  • Going to court (with the captain and perhaps the
    crew)
  • To pay for any damages and fines imposed
  • Getting the bad publicity
  • Paying the bill for everybody else involved
  • Is the only one responsible for the Safety,
    Security and Environmental Condition of the ship
  • Class as an RO are acting on behalf of the
    flag state administration in order help the
    shipowner to comply with statutory regulations.
