Question 1046 Deck General

The correct answer is B) the design does not require a full liquid tight secondary barrier. The spherical type containment system for liquefied gas carriers is advantageous because it does not require a full liquid tight secondary barrier. This is due to the inherent structural integrity and safety features of the spherical design, which can withstand the pressures and stresses associated with liquefied gas cargo without the need for an additional full secondary barrier. The other answer choices are not correct, as the spherical design does not provide any specific advantage in terms of visibility over the bow, and the lack of a full secondary barrier is the key advantage of this containment system.
