PLA General Directions
- No.5 of 2021 - Updated PLA Publications - General Directions 2016 & Permanent NtM Withdrawal
- Feedback on the Public Consultation on the PLA General Directions
The Port of London Authority (PLA), in exercise of its powers under Section 111 of the Port of London Act 1968, as amended (the Act) and as the Competent Harbour Authority under the provisions of the Pilotage Act 1987, and with the agreement of the Chamber of Shipping, repeals the PLA General Directions 2016 and gives the following General Directions to Vessels in the Port of London.
In order to maintain and enhance safety of Navigation on the Thames, it is important that Masters and watchkeepers are familiar with current PLA Byelaws, General Directions and Notices to Mariners. It is therefore vital that owners/agents ensure that all such publications and relevant information are promptly distributed to Vessels as appropriate.
Note should also be taken, as appropriate, of the content of the VHF navigation information broadcasts issued on a regular basis by the PLA VTS centres (London VTS).
It is the duty of the Master of a Vessel to which a General Direction applies to comply with that General Direction. However, the giving of a General Direction does not diminish or in any other way affect the responsibility of the Master in relation to his Vessel, Persons on board, its cargo or any other Person or property (Section 116 of the Act).
Failure by the Master of a Vessel to comply with a General Direction constitutes an offence, and renders that Person liable, on conviction, to a fine up to level 5 on the standard scale. However, it is a defence for the Master of a Vessel to prove that he had reasonable grounds for supposing that compliance with the General Direction in question would be likely to imperil his Vessel or that in the circumstances compliance was impracticable (Section 117 of the Act).
GENERAL DIRECTIONS FOR NAVIGATION IN THE PORT OF LONDON
These Directions shall come into force on 1 March 2021 on which date the General Directions for Navigation in the Port of London 2016 are revoked.

4 GENERIC PASSAGE PLANS AND NAVIGATIONAL RISK ASSESSMENTS
4.1 All Commercial Vessels normally operating primarily in the Thames must prepare and maintain a generic Port Passage Plan and navigational risk assessment, establishing safe air draught and under keel clearances to be maintained, for use during the Vessel’s routine passage and operations in the Thames. All such documents may be inspected by the Harbourmaster.
4.2 Any Vessel which:
a) falls outside the scope of the PLA Marine Safety Management System, and intends to navigate in the Thames, or
b) falls within the scope of the PLA Marine Safety Management System whose operation, in the opinion of the Harbourmaster, causes or is likely to cause a material risk to navigational safety or to the safety of marine operations,
must, when required by the Harbourmaster, provide any information requested in respect of, but not limited to; the Vessel, its equipment, its general condition, certification, organisational and ship management systems, competency of Crew, and be subject to a formal risk assessment, so that the risks associated with the Navigation or operation of the Vessel and any appropriate mitigation of such risks in the Thames can be made.
4.3 Any new intra-port passenger or freight service must not begin, or an existing service be expanded or changed in any way in the Thames, without first submitting passage plans and navigational risk assessments to the Harbourmaster, and subsequently obtaining the Harbourmaster’s formal agreement.
With regard to towage operations, this formal agreement will cover:
(i) the fleet of towing Vessels;
(ii) the number, sizes and arrangements of towed objects;
(iii) the anchoring arrangements;
(iv) berths to be serviced; and
(v) any other mitigation measures, as agreed by the Harbourmaster.
4.4 Vessels applying for a Certificate of Compliance must have their generic Port Passage Plan formally agreed by the Harbourmaster prior to commencing operations.
5 PRE-ARRIVAL AND DEPARTURE NOTIFICATIONS AND INFORMATION
5.1 With the exception of Intra-port Vessels, notice of the intention to navigate a Reporting Vessel in the Thames, including an estimated time of arrival or departure, the Vessel’s ISPS security level, and PEC number (if applicable) must be given to London VTS either 24 hours in advance, or not later than one hour before departure from the last port, berth or offshore operating area, whichever is the latter. London VTS must be notified as soon as practicable if the Vessel is unable to meet that estimated movement time.
Notifications for arrivals from outside the Thames must include a confirmation that the Vessel complies with the navigational safety requirements of these General Directions. This confirmation indicates that:
a) the Vessel’s charts for the Thames and associated navigational publications are corrected and up to date;
b) the Master has prepared an appropriate Port Passage Plan for use during the Vessel’s passage in the Thames;
c) the Vessel, if appropriate, is compliant with the requirements of the ISM Code;
d) if the Vessel is not subject to the ISM Code, that the Vessel has no deficiencies or defects in respect of its manning, navigational equipment, propulsion or manoeuvring machinery; and
e) arrangements have been made to provide appropriate mooring assistance for the Vessel at its intended berth in the Thames.
5.2 A ULCS or a Vessel carrying LNG in bulk must submit a passage plan to London VTS no less than 6 hours before the planned voyage.
5.3 The Master of a container ship greater than 250m in length must submit the calculated lateral windage area for their Vessel:
a) through the Vessel’s shipping agent prior to arriving in the Thames; and
b) to London VTS as soon as loading is completed prior to departure from a berth in the Thames.
5.4 A Specified Vessel must not navigate in the Thames unless notice has been given to the London VTS containing such information as is adequate to evaluate the risk created by the substance carried to the health and safety of any Person not less than 24 hours before so starting or, if the Vessel is an Approved Vessel, as much time before so starting (being less than 24 hours, but not less than 30 minutes) as it is reasonably practicable to give.
Except the above shall not apply where both:
a) the Vessel is navigating into the Thames, including to or from the Medway Ports, from outside the Thames; and

b) in a vertical or near vertical plane facing directly astern;
c) evenly illuminated from sunset to sunrise by suitably screened lights directed onto the reflective material;
d) equally effective in indicating the presence of the Vessel in daylight, as it is when illuminated between sunset and sunrise; and

e) any navigational deficiency, serious defect or any other situation where the Vessel may present an additional risk to port operations during navigation.
7.3 London VTS must be notified 10 minutes before the Vessel gets Underway, moves between berths or shifts at a berth in the Thames. Permission to Proceed must be requested and approved immediately before the Vessel is navigated. If Navigation has not commenced within 15 minutes of the initial advice, London VTS is to be informed.
7.4 When the Vessel passes a reporting point, a report must be made to London VTS that the Vessel is passing that reporting point. When entering a VTS Sector, the report must include the Vessel’s intended route or destination.

12.3 All Vessels required to carry an operational VHF radio in this Direction must:
a) when Underway or at anchor, ensure that an effective, continuous listening watch on the VHF channel used by London VTS in that part of the Thames is maintained by a suitably qualified Person, capable of communicating effectively in English,
b) before that Vessel gets Underway, ensure the appropriate VHF channel used by London VTS is monitored for information that may affect the safe Navigation of the Vessel, including the routine half-hourly VHF navigation information broadcast made immediately prior to the intended departure time.
c) When making special passing agreements with other Vessels, confirm the identity of that Vessel and conduct communication on the appropriate VHF channel used by London VTS to ensure that London VTS and other river users are aware of the Vessels’ intentions.
12.4 Specified Vessels must prefix their Vessel’s name with the word ‘SPECIFIED’ in any VHF communication with London VTS or other Vessel.

1. Any Vessel observing that the extent of visibility at its location is not the distance broadcast by London VTS, or that London VTS is not aware of Restricted Visibility at the Vessel’s location, are requested to report the current level of visibility at the Vessel’s location to London VTS.
15 WATCHKEEPING ARRANGEMENTS
