The Ailsa FSO functions solely as a crude oil storage and export unit. Stabilized oil is transferred from the Solan platform via a dedicated pipeline and riser system into segregated cargo tanks. The vessel is permanently moored and designed to withstand severe metocean conditions typical of the West of Shetland region. Facilities include cargo pumps, crude oil circulation and heating systems, inert gas systems, and custody transfer metering for tanker offloading. Offloading is carried out in tandem to shuttle tankers using flexible hoses. Marine systems include ballast control, bilge systems, dynamic positioning assistance during offloading, and navigation aids. Safety systems comprise fire and gas detection, fixed firefighting systems, and emergency shutdown interfaces with the Solan platform. The FSO does not process hydrocarbons and does not handle produced water or gas beyond basic storage conditioning.
