If you think the human element is the only cause of enclosed space deaths, think again.Enclosed space incidents are cited as the largest cause of on-duty fatalities in commercial shipping. The risks can’t simply be engineered out, but there’s a powerful coalition wanting action nonetheless.There’s a tendency to blame failure to follow procedures, they say. Investigations seldom focus on the practicality of those procedures or the influence of the operating environment and vessel design, they say.

A dynamic era in naval oceanography recently ended as the iconic Floating Instrument Platform — popularly known as FLIP — was officially retired from service.Built in 1962 with funding from the Office of Naval Research (ONR), FLIP helped generations of scientists and oceanographers better understand the mysteries of the sea, including internal waves, air-sea interaction and long-range sound propagation. Sadly, age and exorbitant life-extension costs resulted in the platform being disestablished.On Aug.

Since the ballast water management system discussion started nearly two decades ago, a clear concern was the ability to fit new equipment on existing ships, placing a strain on both space and power. Last month we caught up with a few key suppliers to for their insights on market development.How many BWMS have you sold and installed to date?Maxime Dedeurwaerder, BIO-UV GroupLast year has proven to be the best on record, with roughly 200 BIO-Sea units delivered. All told, since we entered the ballast water market, we have about 700 units in service or pending commissioning.

Freshwater ecosystems are threatened by a host of environmental stressors from human activities. Among the most insidious and impactful of these is invasion by non-native species.Over the past two centuries, established populations of nearly 190 non-native species of invertebrates, fishes, plants and microbes have been discovered in the Great Lakes basin. They were introduced through several sources and pathways including canals, pet release, bait bucket dumping, aquaculture escapes…

French firm GTT has developed a versatile LNG feeder & bunker vessel concept for worldwide operation without the use of ballast water.Every day, many ships carry on board a considerable quantity of seawater as ballast over the oceans. Technically, this is needed in empty or partially loaded conditions, in order to maintain seaworthiness, reach sufficient draft for propeller immersion, and avoid excessive bow slamming.Such ballasting requires investment for the onboard systems and leads to substantial operating costs.

In a webinar on Tuesday, May 17, 2022, Giles Candy will present the advantages for ship owners and shipbuilders with the Scienco InTank Ballast Water Treatment System.The Scienco InTank BWTS treats and neutralizes ballast water in the ballast tanks during the voyage, which allows for normal ballasting and de-ballasting operations in port. It is the only Type Approved “in voyage” ballast water treatment system.A small percentage of ballast water is circulated from one ballast tank at a time. The active substance, Sodium Hypochlorite (NaOCl), is added to the circulation and returned to the tank.

Salvors will remove cargo from the grounded containership Ever Forward as a means to lighten the vessel for another refloat attempt near the Port of Baltimore, the U.S. Coast Guard said on Monday.The Hong Kong-registered containership has been stationary since March 13, when it ran aground outside of the Craighill Channel in the Chesapeake Bay. No injuries or pollution have been reported. Dredgers have been digging out around the stuck box ship, and last week groups of tugboats were twice unsuccessful in trying to dislodge the 1…

Secretary of the Navy Carlos Del Toro announced that a future John Lewis-class replenishment oiler (T-AO) ship will be named USNS Ruth Bader Ginsburg to honor the former Supreme Court Justice and women’s rights activist.The future USNS Ruth Bader Ginsburg (T-AO 212) will be the first U.S. Navy ship to bear her name.“As we close out women’s history month, it is my absolute honor to name the next T-AO after the Honorable Ruth Bader Ginsburg. She is a historic figure who vigorously advocated for women’s rights and gender equality,” said Del Toro.

Salvors will attempt to refloat the Ever Forward on Tuesday following a week of dredging to free the grounded containership outside the Port of Baltimore.According to the port's executive director William Doyle, a team of five tugs, including two pushing on the ship's starboard side, two pulling from port side and one long pull from stern, will aim to dislodge the 1,095-foot ship, which went hard aground outside of the Craighill Channel near Gibson Island on March 13.During the refloat attempt…

Rudy Mes and Giles Candy of Scienco/FAST discuss advantages for ship owners and shipbuilders with the Scienco InTank Ballast Water Treatment System.How doest the InTank system stand out?Rudy Mes We found that most vessels have issues (when) treatment is being done during the intake of ballast water or during de-ballasting, as it puts a strain on power consumption and pump capacity. So we decided we’re not going to treat the water while we’re in port, we’re going to treat it during the voyage.

Ballast water equipment maker Erma First expands its portfolio and brings "the world’s smallest" ballast water treatment system to the international market through its acquisition of US firm oneTANK LLC.oneTANK, a subsidiary of Glosten, developed a small scale innovative, low-cost, IMO Revised G8 Code and United States Coast Guard compliant system.
