Take 10 #42: Understand, identify and navigate restricted areas at sea
Ten tips to help you understand, identify and navigate restricted areas
1 Understanding
The extent of permitted activity in restricted areas varies, from limited use to total exclusion. Make sure you understand what restrictions apply.
2 Purpose
Understand why the restrictions are in place – not just what they are! This supports your ability to make better decisions.
3 Planning
It is essential to take restricted areas into account at the passage planning stage, not just as you approach them.
4 Team work
It is not just the bridge team who need to be aware. Engineers and the company safety team may also need to be kept informed.
5 Situational awareness
If passing close to or between restricted areas, be aware of your safe corridors and ability to manoeuvre to avoid collisions or other operations.
6 Overlap
Watch out for areas where different restricted areas overlap. If you are in an overlap area you must comply with both.
7 Timing
Some restricted areas are time sensitive. This may be to protect animal migration routes, for military exercises or even for emergency situations. Monitor Notices to Mariners and safety messages to ensure awareness and compliance.
8 Recognition
Information about restricted areas uses specific symbols. The way information is presented is different on paper and electronic charts. Further information may be needed from sailing directions or local sources.
9 Change
New restricted areas are being applied all the time. Even if you are on a regular route, don’t assume you know about the areas. Always review the passage plan for each passage and monitor local broadcasts.
10 Mentor
Share your knowledge and understanding of restricted areas with the whole bridge team – do not assume they already know! Only when the whole team has the same understanding will full situational awareness be achieved.
