UK Offshore Safety Zones Order 2026 Explained

If the title made your eyes slide off the page, you are not alone. The Offshore Installations (Safety Zones) Order 2026 is a technical bit of law, but the plain-English version is simple: the UK is keeping protected 500-metre circles around three offshore subsea installations while they are being dismantled or prepared for removal. The text published on legislation.gov.uk says the Order was made on 15 June 2026 and will come into force 21 days later, on 6 July 2026. It was made under the Petroleum Act 1987 after proposals from the Health and Safety Executive, and it applies in UK waters covered by the Act, including territorial waters and designated continental shelf areas. The three named sites are Global Producer III, Solan and Wenlock. This is less about creating brand-new restrictions and more about making sure safety rules stay clear while old infrastructure is coming apart.

A safety zone is exactly what it sounds like: a protected area around an offshore installation. In this Order, each zone has a radius of 500 metres from a fixed point listed in the Schedule. Those points are given as latitude and longitude using WGS 84, the standard reference system used in modern navigation so that ships, charts and positioning tools are all working from the same map language. **What this means for you:** if a vessel is travelling through those waters, it generally cannot enter or remain in that 500-metre zone unless the Health and Safety Executive gives consent, or unless an existing regulation allows it. The rule is broader than many people might expect. It applies not just to ships, but also to hovercraft, submersible apparatus and installations in transit. The legal wording is dense, but the safety message is easy to follow: where offshore work is under way, give it space.

The most useful piece of context is that these three locations already had automatic safety zones. The new Order copies that protection into a specific legal instrument so that the zone stays in place while decommissioning work continues. In other words, this is a continuity measure. It keeps the safety cordon going during a messy middle stage when an installation is no longer in ordinary use but has not yet fully disappeared. The explanatory note on legislation.gov.uk gives the timetable. Global Producer III is intended to be removed by the end of 2027. Solan is intended to be removed by the end of 2029. Wenlock is already being dismantled. That matters because a structure being taken apart can still be hazardous to nearby traffic. For mariners, fishers and offshore operators, the practical lesson is clear: a site on its way out can still be a site you need to avoid.

This Order also clears away some older entries from previous legislation. It amends the 1997 Offshore Installations (Safety Zones) Order to remove Thames Bure Wellhead and Thames Yare Wellhead. It also amends the 2007 Offshore Installations (Safety Zones) (No. 7) Order to remove the Victoria Subsea Production Well in Block 49/17, Victoria Field. That may sound like routine legal housekeeping, and in one sense it is. But it also shows how offshore regulation actually works. Safety zones are not frozen forever. They are added, copied, amended and removed as installations change status. So when you read a dry statutory instrument like this one, you are really looking at the law catching up with a changing seascape of energy infrastructure, dismantling work and navigation risk.

If you are wondering how anyone is supposed to know where these invisible circles begin and end, the explanatory note on legislation.gov.uk gives a practical answer. Mariners are pointed to the UK Hydrographic Office, whose nautical charts show offshore installations and, where the chart scale allows, the location of safety zones. Paper chart users are told to keep those charts up to date through Notices to Mariners. Electronic chart users are expected to subscribe to updating services. The note also reminds readers that some vessels are already required to carry charts and navigational publications under wider shipping safety rules, including the Merchant Shipping (Safety of Navigation) Regulations 2020. This is worth pausing on. Maritime safety is not only about what is in the water; it is also about whether the people on board have current information in front of them.

There is another layer too. Where chart corrections have not yet worked their way through, maritime safety information can still be broadcast through radio navigational warnings and through the wider Global Maritime Distress and Safety System. The legislation also points to the recognised warning systems used for international maritime safety messages. **Why that matters:** sea traffic does not stop while paperwork catches up. Offshore installations can be moved, dismantled or left in transitional states, and navigators still need clear information in real time. Broadcast warnings fill the gap between a legal change being made and every printed or digital chart reflecting it. It is one of those quiet public-safety systems that most of us never think about until we realise how much could go wrong without it.

The government says no full impact assessment has been produced because no significant effect on the private, voluntary or public sector is expected. That line often appears in technical legislation, but it is still worth reading carefully. No major economic impact does not mean no practical impact at all. For the people plotting routes, managing offshore works or teaching maritime law, these rules still shape day-to-day decisions. If you are reading this as a student, teacher or curious general reader, this Order is a good reminder that public law often works through small, precise adjustments rather than big political speeches. A short instrument, signed on 15 June 2026 by Minister of State Stephen Timms on the authority of the Secretary of State, keeps a 500-metre buffer in place while offshore sites are dismantled. The language is technical, but the idea is not: when industrial structures are still out at sea, even on their way out, the safety rules stay with them.
