A double-hull sea-going tanker is a type of tanker vessel that has two layers of structural protection against oil spills and pollution. The space between the two hulls is used as a safety margin and allows for early detection of leaks or other damages. This design was introduced to reduce the risk of oil spills in the event of an accident or collision.
In this case, the specific vessel is a chemical tanker that was constructed in Hamburg, Germany in 1973. It has a length of 82.80 meters, a beam of 11.80 meters, and a deadweight tonnage of 2078 on a draft of approximately 4.76 meters. The vessel is classified by DNV GL as 1A Ice-1b tanker for chemicals flashpoint above 60°C.
The tanker has a double hull and four cargo tanks with a total capacity of 1452 cubic meters. The tanks are not coated and are equipped with a thermal heating system that can heat up to 240 degrees Celsius. The vessel is powered by a MaK 323 engine with a power output of 1000 kW, which allows it to travel at a speed of about 9.5 knots while running on marine gas oil (MGO). It also has three auxiliary engines, including two Deutz engines and one Cummins engine.
The tanker is equipped with complete navigation and safety equipment, including pumps, cargo and ballast systems, and heating systems, to ensure safe and efficient operation. It underwent its last drydocking in Tallinn, Estonia in November 2020, and its next scheduled special survey (SS) is due on June 30, 2023.
