4 terms

memorandum of agreement regulatory

"announced today the signing of a tri-party Memorandum of Agreement – joining forces"

A memorandum of agreement is a written document that outlines the key terms and understanding between two or more parties planning to work together or make a deal. It serves as a clear record of intentions and commitments, helping to prevent misunderstandings. For investors, it provides reassurance that the involved parties have agreed on important details before finalizing a formal contract.

next generation logistics ship (ngls) technical

"including the U.S. Navy's Next Generation Logistics Ship (NGLS), and will leverage"

A next generation logistics ship (NGLS) is a modern cargo vessel designed to transport goods more efficiently, sustainably, and with advanced technology. It often features innovations that reduce costs, lower environmental impact, and improve speed and safety. For investors, these ships represent developments in global trade infrastructure that can influence shipping costs, supply chain reliability, and overall economic growth.

lngc technical

"Its portfolio includes liquefied natural gas carriers (LNGC), container ships, drill ships"

A liquefied natural gas carrier (LNGC) is a specialized ship that transports natural gas cooled into liquid form so it can be moved long distances by sea. Investors watch LNGCs because they are critical links in the fuel supply chain—like refrigerated vans for perishable goods—so demand, availability, and regulation of these vessels affect energy company revenues, freight rates, and the broader supply and price stability of natural gas.

flng technical

"top global market share in drill ships, LNG carriers, and floating LNG production units (FLNG)."

A FLNG is a floating facility — basically a factory on a ship — that extracts, processes and cools natural gas at sea so it can be loaded onto tankers and sold as liquefied natural gas. For investors it matters because FLNG projects can unlock remote offshore gas resources without building long pipelines, but they require large upfront spending, carry construction and safety risks, and can strongly influence a company’s future cash flow and profit when production begins.
