Overview

About This Vessel

Diamond Princess is a British-registered cruise ship owned and operated by Princess Cruises. She began operation in March 2004 and primarily cruises in Asia during the northern hemisphere summer and Australia during the southern hemisphere summer. She is a subclassed Grand-class ship, which is also known as a Gem-class ship. Diamond Princess and her sister ship, Sapphire Princess, are the widest subclass of Grand-class ships, as they have a 37.5-metre (123 ft 0 in) beam, while all other Grand-class ships have a beam of 36 metres (118 ft 1 in). Diamond Princess and Sapphire Princess were both built in Nagasaki, Japan, by Mitsubishi Industries. There have been two notable outbreaks of infectious disease on the ship – an outbreak of gastroenteritis caused by norovirus in 2016 and an outbreak of COVID-19 caused by SARS-CoV-2 in 2020. In the latter incident, the ship was quarantined for nearly a month with her passengers on board, and her passengers and crew were subject to further quarantine after disembarking. At least 712 out of the 3,711 passengers and crew were infected, and by mid-April 2020 nine had died.

Port calls

12 recent · AIS-detected

Arrivals, time in port and the load/discharge inferred from the draught change, detected from AIS track history. An open call means the vessel is still in port (no departure observed yet).

Method: each call is a run of fixes inside a port’s geofence confirmed by a stop (or an AIS gap); load/discharge is the sign of the draught delta over the call. Indicative: arrivals before our AIS history began read from the first observation.

A coverage-weighted blend of the single component we could read for this hull; the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
