Question 4301 Deck General

The correct answer is B) better identify the correct reading. When taking soundings on a mobile offshore drilling unit (MODU), coating the tape with chalk helps to better identify the correct reading. The chalk helps to make the markings on the tape more visible, allowing the operator to more accurately read the sounding depth. This is important for safety and regulatory compliance when monitoring the levels in various tanks and compartments on the MODU. The other options are incorrect because: A) reducing the possibility of sparks is not the purpose of using chalk on the sounding tape, C) making the tape roll easier is not the main reason, and D) showing the depth of water in an oil tank is not the primary function of the chalk.
