What does DHT mean in UNCLASSIFIED

What is a DHT?

A DHT is a type of tanker ship equipped with two separate enclosures for fuel tanks. The extra enclosure acts as a safety barrier between the tanker's cargo tanks and any possible external hazards - such as impact from another vessel, or structural damage due to rough seas - that could create a breach and lead to oil spillage. DHTs also benefit from improved thermal insulation, reducing temperature-related stress on the cargo tanks which can cause cracks and leaks in older tankers without double hulls. As a result, DHTs offer greater environmental protection than traditional single-hulled tankers while still providing reliable transport of crude oil and petroleum products.

Benefits of Double Hulled Tankers

The primary advantage of double hulled tankers is enhanced safety and fewer risks associated with transporting hazardous materials like crude oil and petroleum products at sea. By providing additional structural integrity, double hulls significantly reduce the risk of leaks during collisions or adverse weather conditions which could otherwise lead to damaging oil spills - both in terms of their ecological impact as well as potential fines or criminal charges levied on those responsible for operating unsafe vessels. Additionally, they also provide better thermal insulation which helps maintain consistent temperatures inside the cargo tanks, further reducing the risk of accidental spills caused by heated contents expanding and creating cracks in weakened hull plating.
