Singapore Registry of Ships (SRS)
The Singapore Registry of Ships (SRS) is the register, administered by the Maritime and Port Authority (MPA), under which ships are registered to fly the Singapore flag. It is one of the world's largest ship registries by tonnage and is regarded as a high-quality flag — consistently white-listed under the Paris and Tokyo Memoranda of Understanding on port state control.
Registration is open to Singapore-incorporated companies (and qualifying foreign owners through a local entity) that meet MPA's criteria. The SRS offers a competitive tonnage-based tax regime and access to Singapore's deep maritime services ecosystem — financing, insurance, arbitration and ship management — which is a major draw for owners choosing a flag.
A ship's flag determines its regulatory regime, port-state reputation and tax treatment. The Singapore flag combines a quality, white-listed register with a competitive tax regime and a world-class maritime cluster — which is why so many owners register here rather than at a flag of convenience.
