The newly commissioned Siem Aristotle joins sister ship Siem Confucius as the world’s largest liquefied natural gas (LNG)-powered pure car/truck carrier (PCTC) vessels.Operating exclusively for Volkswagen Group, the Siem Aristotle is the second in a series of two Super-Eco ships for the Siem Car Carriers fleet that run on cleaner burning LNG fuel to help reduce vessel emissions.The vessel's carbon dioxide emissions are slashed by up to 25%, nitrogen oxide emissions by up to 30%, particulate matter by up to 60% and sulphur oxide emissions by up to 100%, according to the shipowner.

An unmanned vessel is now surveying more than 3,500 nautical miles of the Western Galveston Bay, near the Houston Ship Channel.DEA Marine Services, a division of David Evans and Associates, Inc. (DEA), in Vancouver, Wash., equipped its survey boat Sigsbee with a Sea Machines Robotics SM300 autonomous-command and remote-helm control system to fulfill a National Oceanic and Atmospheric Administration (NOAA) contract.Sigsbee, which is serving as an autonomous daughter craft for the project, is effectively doubling coverage by operating without an onboard crew, while collaboratively following another DEA-staffed hydrographic survey vessel, which serves as the mothership.

Havyard said Monday it has been contracted to develop a new emissions-free ship concept for transporting cargo between European ports.The contracting partner, an unnamed European company, was first introduced to Havyard by Invest in Norway, who has been working with this company for the last two years in supporting their entry to the Norwegian maritime industry, Havyard  said.Lars Conradi Andersen, Vice President Sales, said, "The framework for this contract is to develop a ship that uses hydrogen-based fuel as its primary energy source while at the same time giving the client an effective and safe ship. The goal is to design a large ship that can sail longer distances with zero emissions.

The United States often sends ships and aircraft into the South China Sea to “flex its muscles” and this is not good for peace, China’s Foreign Ministry said on Monday, after a U.S. aircraft carrier group sailed into the disputed waterway.The strategic South China Sea, through which trillions of dollars in trade flows each year, has long been a focus of contention between Beijing and Washington, with China particularly angered by U.S. military activity there.The U.S. carrier group led by the USS Theodore Roosevelt and accompanied by three warships, entered the waterway on Saturday to promote “freedom of the seas”, the U.S. military said, just days after Joe Biden became U.S. president..

Guyana said late on Saturday that a Venezuelan navy vessel detained two vessels that were fishing in Guyana’s exclusive economic zone, the latest dispute in a long-running border conflict between the two South American nations.Caracas says much of eastern Guyana is its own territory, a claim that is rejected by Georgetown. The conflict has flared up in recent years as Guyana has started developing oil reserves near the disputed area.“The Venezuelan vessel was illegally maneuvering within Guyana’s EEZ and Contiguous Zone when it intercepted, boarded and commandeered the Guyanese fishing vessels,” Guyana’s foreign ministry said in a statement.
