I recently completed a commission for the offices of ITOPF in London.
From their website:
ITOPF (International Tanker Owners Pollution Federation), has responded to over 860 incidents involving oil, chemical or cargo spills worldwide. Our highly skilled international team are ready to assist 24 hours a day, 365 days a year to provide impartial technical advice. ITOPF operates on a not-for-profit basis.
