Question 3599 Deck General

The correct answer is A) Once every three months. This is the correct answer because the Code of Federal Regulations (CFR) requires mobile offshore drilling units to conduct a drill on the use of the line throwing appliance at least once every three months. Specifically, 46 CFR 109.213(d) states that "The master shall ensure that the line-throwing appliance is readied for immediate use and that a drill on the use of the line-throwing appliance is conducted at least once every 3 months." The other options are incorrect because they do not align with the regulatory requirement. Once a year (B), once a week (C), and once a month (D) are all intervals that are either too long or too short compared to the three-month requirement specified in the regulations.
