Marbdy Consulting Limited provides expert technical support for maritime boundaries, and specifically for dispute resolution either through negotiation or third-party arbitration.


Robin Cleverly outside the ICJ

Dr Robin Cleverly founded Marbdy Consulting Ltd in March 2015 to supply expert technical advice in the field of maritime boundary determination particularly dispute resolution, principally to governments and law firms. This follows on from 25 years as a geologist in the oil industry with BP, 4 years as exploration manager with a specialist satellite mapping company (Nigel Press Associates), and 15 years working in the specialised field of maritime boundaries, ultimately as Head of the Law of the Sea Group at the UK Hydrographic Office. He has worked extensively on international maritime boundary court cases at the ICJ, ITLOS and Annex VII tribunals, and also on outer continental shelf submissions before the CLCS. He is a co-author with Stephen Fietta of “A Practitioner’s Guide to Maritime Boundary Delimitation” published in March 2016 by Oxford University Press.
