Description

Lecture evening with topic:
"DIFIS - Double Inverted Funnel for the Intervention on Ship wrecks"

The scope of the DIFIS project is the study, design and validation of an EU reference method for the prompt and cost-effective intervention on ship wrecks. The proposed method is of general applicability as long as the trapped pollutant does not dissolve and is of lower density than sea water.
The leaking fuel is collected by a Dome, constructed of fabric, covering the ship wreck completely. The collected fuel is channelled, along with sea water, through a long, flexible Riser Tube into a Buffer Bell, which is at a depth of 30-50 m below the sea surface. The Buffer Bell acts as separator and temporary storage for the oil. The storage capacity will be typically 1,000 tonnes or more. The Buffer Bell keeps the Riser Tube and Dome under tension and provides for a rapid periodical unloading to a shuttle tanker.

MARIN carried out two series of model tests. In the first set of model tests, carried out in MARIN's Offshore Basin in March 2007, the performance of the DIFIS system was tested in Operational Conditions and during Offloading Operations. The results of the measurements were used as input for the design of the DIFIS system. In January 2008, a second set of tests was carried out, focussing on the deployment of the system. The results of these tests were used to evaluate the system's installation procedure.
