Hangtong Shipbuilding Industry has completed the second trial voyage of a 7999 ton dual fuel refueling vessel

On July 12th, the 7999DWT dual fuel refueling bow vessel "AMALTHEA" built by Jiangmen Hangtong Shipbuilding Industry successfully completed its oil and gas two in one trial voyage.

The "AMALTHEA" vessel has a total length of 103.88 meters, a width of 19 meters, a depth of 10 meters, a design draft of 7.2 meters, and a carrying capacity of 7999 tons. It is classified by the French Classification Society (BV) and is suitable for transporting fuel, gasoline, and other petroleum products listed in MARPOL Appendix I. The ship is equipped with dual engines and twin propellers, with a bulbous bow and a vertical square tail, and has a continuous freeboard deck.
