Reporting Navigational Incidents & Safety Concerns
The achievement of safe marine operations on the tidal Thames is the responsibility of all users, not solely the PLA. Vessel masters and those in charge of vessels using the Thames are required, under the provisions of PLA Byelaws, to report specific categories of incident to the PLA. All navigational incidents are fully investigated by the relevant district Harbour Master, with some incidents also investigated by the Marine Accident Investigation Branch (MAIB) and occasionally the Maritime & Coastguard Agency.
In addition to this legal requirement, all river users are invited to report any navigational incidents or occurrences (including near misses or any general safety concerns) so that any matters arising can be properly considered by the PLA.
Urgent navigational matters must always be reported immediately to the Harbour Master through the appropriate VTS Centre at Gravesend or Woolwich.
In this instance Telephone or VHF Reports should be made to:
Port Control Centre, Gravesend - For incidents between the outer PLA limits at NE Spit and Sunk pilot stations and Crayfordness
|VHF Channels:||Outer Limits to SR No. 4 Buoy –||Channel 69|
|SR No. 4 Buoy to Crayfordness –||Channel 68|
|Telephone:||Duty Port Controller||01474 560311 (24hrs)|
Thames Barrier Navigation Control Centre, Woolwich - For incidents between Crayfordness and the landward PLA limit at Teddington
|VHF Channels:||Crayfordness to Teddington -||Channel 14|
|Telephone:||Duty Officer||0203 260 7711 (24hrs)|
When reporting non-urgent navigational incidents, or following a request from the investigating Harbour Master to provide a written report, one of the following Report Forms should be completed as appropriate:
Navigational Incident/Near Miss Reporting Form
This form can also be used to report deficiencies of safety equipment, unsafe practices, or contravention of regulations at a jetty, wharf or pier.
Click here for a PDF version of the Form. This can be printed and completed by hand or completed online.
Incidents Involving Rowing Craft
The Thames Regional Rowing Council (TRRC) has an online incident reporting system for all incidents involving rowers on the tidal Thames.
This reporting system is not limited to the rowing community and the TRRC would ask non-rowers to use it if they are involved in or witness an incident involving rowing craft. Using this reporting system does not remove the requirement to complete a PLA Incident Report Form when this is required.
The online reporting system can be accessed here (opens in a new window)
All incident and near miss reports should be sent to the relevant district Harbour Master:
Outer Limits to Crossness
Crossness to Teddington
Harbour Master (Lower)
London River House
Royal Pier Road
Kent DA12 2BG
Harbour Master (Upper)
23 - 26 St Dunstan's Hill
London EC3R 8HN
