Peterhead Bay Harbour is a deep water natural inlet protected from the sea by two breakwaters. Within the sheltered harbour there is approximately 2.1km of alongside berthing, with minimum water depths of up to 14 meters at low tide. A comprehensive range of supporting services and facilities cater for most types of marine traffic. The port developed round the North Sea oil and gas industry but in recent years has diversified the range of vessels and commodities handled to include cruise vessels, bulk agricultural products, frozen fish and pleasure yachts. The oil industry still forms the core of the port's business which includes sectors such as oil rig IRM, survey, diving support, offshore logistics, safety vessels, subsea construction and decommissioning.
