Maritime Boundary Delimitation

Professional Training Workshop

26-28 June 2017
London, UK

Clearly defined maritime boundaries are essential for good international relations and effective ocean management, yet few coastal states have agreed all their maritime boundaries with their neighbours. Part of the reason for this is that boundary delimitation requires a range of specialist legal and technical skills which are not always readily available to governments.

Combining lectures, discussions and practical exercises, IBRU's most popular workshop helps participants develop the skills needed to achieve an equitable division of maritime space and clearly defined maritime boundaries.

The cost of the workshop will be £2,280 (£1900 + VAT ) per participant

This fee does not include accommodation.
