4. Specific legal prophylaxis in waters next to Greenland
In addition to the afore mentioned international legal regulations, navigating in Greenlandic waters is specifically regulated by a number of regulations which have been adopted by the IMO and devised as national regulation. In relation to Greenlandic waters, the Executive Orders’ on reporting and piloting obligations are most central. These two Executive Orders cover, what in this article is termed as legal prophylaxis, i.e. provisions whose overall aim is to improve maritime safety for passenger ships (and also for commercial shipping) navigating in Greenlandic waters. Section 4.1 begins with a presentation of the executive order on the duty to report and then section 4.2 follows with an analysis of requirements on the use of people with local knowledge or an actual piloting obligation.
