Supporting safe, secure and thriving oceans
In an ever-changing world, our oceans are under increasing pressure with advances in technology, busier seas and pressing environmental challenges. Our experts support safe navigation across the globe by providing hydrographic understanding to inform maritime decisions from ship to shore.
Our role in government
Working as an executive agency of the Ministry of Defence, we play a leading role in providing expert advice on hydrography to the UK and international governments. We source, compile and analyse a wide range of data to help our partners build an understanding of the marine environment.
For safer navigation
The UKHO provides hydrographic understanding to help our partners and mariners use the world’s oceans in safer and more sustainable ways.
For over 225 years our global portfolio of ADMIRALTY charts, publications and digital services have been trusted by mariners and shipping companies for safe, compliant and efficient navigation.
Supporting defence with specialist expertise
In the UK, the Royal Navy and other defence users rely on our hydrographic data and expertise for safe navigation and to support operations that help promote peace on a global scale.
