ANCHORING AND TRAWLING
Ships are prohibited from anchoring and trawling in the area marked by T-shaped dashed lines due to the existence of oil and gas pipelines carrying flammable material under high pressure or the submarine cable of high voltage. Mariners risk prosecution if they anchor or trawl near a pipeline or a cable and so damage it. Any ship damaging them could face an immediate hazard. Mariners are strongly advised not to anchor or trawl in the vicinity of pipelines or the submarine cable. See Annual Notices Nos. 14 and 21.
