Marine Plan for Northern Ireland

The Marine Plan for Northern Ireland will inform and guide the regulation, management, use and protection of our marine area. It is a single document made up of two plans, one for the inshore region and one for the offshore region.

Why is there a Marine Plan?

The Marine and Coastal Access Act 2009 (MCAA) and the Marine Act (Northern Ireland) 2013 (The Marine Act), require the Department of Agriculture, Environment and Rural Affairs (DAERA) as the Marine Plan Authority (MPA), to prepare marine plans. The Marine Plan has been developed within the framework of the UK Marine Policy Statement (UK MPS). This will facilitate the sustainable development of the marine area. 

The UK Government has published a 25 year Environment Plan that commits to having UK Marine Plans in place by 2021.

Where is the Marine Plan area?

The Northern Ireland marine area is made up of an inshore and an offshore region.  The marine area comprises all marine waters including sea bed, subsoil, sea loughs and tidal rivers, so far as the tide flows at Mean High Water Spring Tide.

The inshore region extends from the Mean High Water Spring Tide mark out to, at most, 12 nautical miles (nm) and includes tidal rivers and sea loughs.  The offshore region is the area that extends south-eastwardly from the 12nm territorial limit to the outer boundary of the Northern Ireland marine area (31nm at the farthest point). 

Who will use the Marine Plan?

The Marine Plan will primarily be used by public authorities taking decisions which affect or might affect the marine area.  It will also be used by anyone who has an interest in the marine area, including those bringing forward proposals and stakeholders who wish to comment on such proposals.

How does the Marine Plan affect decision making?

The Marine Plan (when adopted) will be used by Public Authorities in taking decisions which affect or might affect the marine area, including:

When will the Marine Plan come into effect?

The Marine Plan will come into effect when it is published in final form and adopted. 

Getting involved

The involvement of those with an interest in and responsibility for the marine area has been central to the development of the Marine Plan, as set out in the Statement of Public Participation (SPP).

We encourage anyone with an interest in marine planning to get in touch. You can be added to our stakeholder list to receive updates on progress and information on upcoming events. During the public consultation on the Marine Plan you can comment with your view on the policy proposals.


The Marine Plan has been informed by a Sustainability Appraisal, which incorporates the requirements of a Strategic Environmental Appraisal.

Progress and Reporting

The Marine Plan newsletter can provide you with information on the current position with the Marine Plan.

DAERA is required by legislation to prepare a Marine Plan report on the Marine Plan process in Northern Ireland.
