Paris Mangriotis will be presenting navigation issues which have led to marine incidents resulting in the need for salvage and major wreck removals.

Background will be provided on incidents such as Ever Given, Hoegh Osaka and the Costa Concordia.

There will be a discussion of wreck removal techniques, in particular the Costa Concordia operation, which was unique in terms of scale, technical complexity, number of stakeholders and cost.

The focus will be on the technical challenges of refloating a damaged 45,000 tonne wreck and transporting it safely for recycling. The reasons for the choice of method and subsequent impact on all aspects of the project will be summarised.

Of particular interest is the convergence between emergency wreck removal and major maritime civil engineering work. Paris will provide some insights to the challenges of such operations involving dredging works, large diameter boring, excavation, subsea installation of seabed platforms and underwater clean up works.

What issues are thrown up when such operations, usually planned over months or years for a conventional project are performed in an emergency context?




PIANC provides access to worldwide trends and challenges in port and waterway development and management.
