The Herald of Free Enterprise inquiry examined the capsizing of a P&O ferry at Zeebrugge on 6 March 1987, which resulted in 193 deaths. The vessel had sailed with its bow doors open. Mr Justice Sheen's report, published within four months, identified failures in safety procedures and management systems.

The inquiry's 27 recommendations addressed immediate operational concerns and broader regulatory frameworks. At the operational level, the report recommended bow door indicators, closed-circuit television surveillance, and enhanced stability testing. These measures were incorporated into UK regulations through the Merchant Shipping Act 1988, which also created the offence of unsafe ship operation.

At the international level, the inquiry contributed to the development of the International Safety Management Code, adopted by the International Maritime Organization in 1993. The ISM Code requires shipping companies to establish documented safety management systems and became mandatory for most commercial vessels from 1998.

The failed prosecution of P&O for corporate manslaughter highlighted limitations in English criminal law regarding corporate liability. This case, where prosecutors could not identify a single 'directing mind' responsible for the disaster, became a reference point in debates that eventually led to the Corporate Manslaughter and Corporate Homicide Act 2007.

The inquiry stands as an example of how maritime disasters can produce regulatory changes at both national and international levels, influencing safety standards beyond the immediate circumstances that prompted the investigation.
