As of today, NHO has issued 19 navigation charts as part of a comprehensive production plan to cover most of the Omani maritime areas. 3 more charts are in progress and shall be released shortly.

The Office also produces weather publications such as Oman Maritime Handbook, which is issued annually and includes a list of navigational lights utilised in Omani Waters along Omani coast, alongside some navigational lights used in the Waters of neighbouring countries in Arabian Gulf and Gulf of Oman.

Internationally, NHO plays a key role in delineating and defining the Sultanate maritime borders with her neighbours, and offers relevant advice to governmental authorities, from the technical and executive perspectives in particular.

Moreover, NHO has conducted several premium technical studies regarding the delineation of Omani maritime areas such as Internal Waters, Territorial Sea, Bordering Area, and Economic Exclusive Zone (EEZ) as per the stipulations of the International Law of the Sea. To store these information, NHO setup a database which also maintains maritime areas operated by RNO to run its exercises and manoeuvres.
