To ask the Secretary of State for Transport, with reference to paragraph 2.4 of the Impact Assessment of the Harbours (Seafarers’ Remuneration) Bill, if he will publish the past data used to estimate the number of journeys made by vessels assumed to be in scope.

The Impact Assessment published alongside the public consultation (https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1074053/impact-assessment-harbours-seafarers-remuneration-bill.pdf) uses data from DfT port freight statistics Dataset port0601, which is published and available online at (https://www.gov.uk/government/statistical-data-sets/port-and-domestic-waterborne-freight-statistics-port). This contains data on the frequency of port calls per year, and vessel type, meaning that the scope of preferred option in the consultation Impact Assessment, covering ropax and roro vessels calling in UK ports at least weekly, covers 64,000 vessel-journeys (based on the 2019 data). The Impact Assessment also utilises vessel-level data on port calls frequency, however, as this vessel-data is commercially sensitive, the Department does not publish it.
