The supplied sources do not identify one IMO requirement as the clear largest workload or cost driver for operators. They do, however, point to two practical compliance pressures. First, disruption around the Strait of Hormuz— including sharply reduced vessel traffic and a proposed exclusion zone—creates uncertainty for routing, voyage planning and operational decisions, although the sources do not quantify the resulting compliance costs. Second, the IAPH–IHMA Port Call Optimization Guide promotes harmonized electronic exchange of nautical and operational data, with trialled data sets intended to support safer, more predictable and sustainable port calls. This appears relevant to documentation and digital-process burdens, but implementation detail is limited. Which electronic data exchanges are currently creating the greatest workload for your port or fleet?
