​The QUALSHIP 21 program (United States Coast Guard's Quality Shipping for the 21st Century Program) has existed since 2001, helping improve safety of shipping by identifying high-quality ships and thus promoting ship quality standards.

Danish shipping is quality shipping. Safety and growth are the hallmarks of quality shipping, and therefore I am pleased that Danish shipping continues to live up to these high standards,

...says Andreas Nordseth, Director General of the Danish Maritime Authority.

The requirements for QUALSHIP 21 are higher than ever. For instance, it is now a requirement that the share of a flag's retained vessels over a 3-year period must be less than 1%.

Danish vessels distinguished themselves in this regard by the fact that only one vessel has been detained in the past 3 years (0.37%), and no Danish vessels have been detained in the USCG for the past 2 years.

QUALSHIP 21 is the port state control of the US in the same way as the Paris MoU and Tokyo MoU. Currently, 27 countries hold the QUALSHIP 21 certificate.

Furthermore, Denmark is at the top of the so-called White Lists within the port state control regimes Paris MoU and Tokyo MoU.

The US Coast Guard closed the QUALSHIP 21 program for the calendar year 2018 with an enrollment of 2,213 vessels, compared to 2,013 last year.
