Reverse Osmosis and the New Dawn of Marine Desalination

(Image: FCI Watermakers)

Today’s desalination plants are rugged, durable and highly automated to meet the demands of operators and the crew, enabling them to meet schedule and mission with ample potable water production.In the days of old, marine distilling plants – then mostly steam – relied on archaic flash evaporators, which used steam to heat, power an air ejector, and ultimately create a vacuum whereby seawater would flash or boil and ultimately be distilled. The process would often occur over two stages and what did not flash would be pumped overboard as brine. Times have changed.

Bunkering ports around the world have long used a variety of small tankers or tug and barge combinations to deliver fuel to visiting ships. Mostly this was heavy oil, but recently a new breed of bunkering vessels is emerging to deliver clean burning liquefied natural gas (LNG) to modern ships with dual-fuel capabilities.The fall of 2020 will see a new addition to this fleet servicing ships in Florida and the Caribbean. As an articulated tug barge (ATB) combination, the vessel will have a cargo capacity of 4,000 cubic meters of LNG.

Ballast Water Update: Weighing the Advent of VIDA

Captain Sean T. Brady, Chief of the Coast Guard’s Office of Operating and Environmental Standards (OES)

The hard-fought passage of VIDA promises a simpler, more unified and logical set of environmental standards related to the discharge of myriad vessel streams. Industry wanted it, and now it is here. Will it deliver, and if so, when? That depends on who you talk to.As most commercial maritime operators know, US ballast water regulations made a sharp turn last December. That’s when President Trump signed the Frank LoBiondo Coast Guard Authorization Act of 2018.That legislation contained Title IX – the “Vessel Incidental Discharge Act (VIDA)…
