  • 1.) Wreck survey – selecting the primary

targets (high potential for oil pollution, New Data Base

  • 2.) Validation of the wreck model

(Vraka)

  • 3.) Modification of the existing wreck

model to also include the risk assessment of different salvage

  • peration alternatives
  • 4.) Developing innovative

technological solutions for oil removal

  • perations,
  • Salvage Toolbox Development

Wreck alert cases in Summer ?

  • 30.6. case in

Sweden

  • In August expected

wreck case in Finnish Archipelago – the detected oil spill was probably due to the lubrication oil leakage through propeller shaft’s sealing – wreck ”Brita Dan”was checked.

  • Old wreck register made already in 1990…1999
  • Register contains more than 1 100 objects
  • Wrecks have been categorized based on the expected

amount of oil onboard

  • Priority has been on the expected amount fo oil onboard
  • Sensitive areas and/or water depth on site have been

”ignored”

  • Potential for salvage operations ”ignored”
  • Novel idea under swera is to select ”hot spots, based on

different categorization (VRAKA?)

  • Selected objects will be put to the BORIS-2 data base
  • Helcom has its own Map and Data service

  • Based on surveying (Maritime administration)
  • Side Sweep sonar readings of Coast Guard
  • Data contains numerous underwater objects
  • Part of these wrecks have been confirmed by divers &

reports

  • Amount of oil has not been studied at all
  • Work continues…..
  • Naval forces might have some confidental data
  • War objects under the War Museum
  • Finnish Maritime Museum has their own register

(arhealogical objects)

  • The main objective of the LIFE-OILREMOVAL project is to

demonstrate and validate new and innovative tools for oil removal from sunken wrecks having oil or packaged dangerous goods

  • nboard.
  • Second objective of this proposal is through the surveys based on

preselected targets to validate modern smart sensor technologies to help the authorities and municipalities to evaluate the salvage potential of certain target with the suitable risk approach.

  • Third objective is to select suitable underwater object(s) for oil

removal demonstration(s). The selected underwater objects may be a sunken ship of container with dangerous goods onboard.

  • Final goal is to produce a toolbox to evaluate the threat for oil

pollution and to select technical proper means for salvage and

  • il/chemical removal operations.

  • Analyses of the salvage-oil removal
  • perations
  • Field surveys & demonstrations

based on new innovative sensor techniques

  • Full-scale oil removal operation
  • Risk analyses and operational

procedures
