US-based shipbuilding company General Dynamics NASSCO has delivered the fourth vessel of a series of five ECO class product tankers to American Petroleum Tankers.

Bay State, the newly delivered vessel, is 610ft long and has a deadweight tonnage (dwt) of 50,000.

The liquefied natural gas (LNG)-conversion-ready product tanker has the capacity to carry 330,000 barrels of cargo.

"We take pride in knowing we are delivering another high-quality vessel to our partner, American Petroleum Tankers."

General Dynamics NASSCO vice-president and general manager Kevin Graney said: “The Bay State is the product of world-leading design, engineering and construction.

“We take pride in knowing we are delivering another high-quality vessel to our partner, American Petroleum Tankers.”

Build in accordance with the Jones Act, which mandates the building of ships carrying cargo between US ports in shipyards, the new ECO Class tankers’ construction was started in May last year.

Over the last decade, NASSCO delivered 28 ocean-going ships to various government and commercial customers.

The company has also collaborated with South Korean shipbuilding group, Daewoo Shipbuilding & Marine Engineering (DSME), to gain access with design and shipbuilding technologies.

Meanwhile, NASSCO has started construction of the Palmetto State, which is the eighth ship to be constructed under an eight-ship ECO class tanker programme for two separate customers; American Petroleum Tankers and SEA-Vista.

The first five ships of the programme have already been delivered, while the rest of three ships are under construction. The Palmetto State is scheduled to be delivered next year.
