The Project Forward initiative led by Athens-Based Arista Shipping, with Wärtsilä as one of the participants, demonstrates that with LNG as fuel, an advanced hull design, and highly efficient propulsion machinery, it will be possible to meet the IMO’s target for a 40 percent reduction in carbon intensity by 2030.Model tests of the Project’s concept vessel indicate that the Energy Efficiency Design Index (EEDI) is well below the currently most stringent Phase III level. The EEDI reflects the CO2 emissions per transport work and is a measure of carbon intensity.

The U.S. Coast Guard has issued an alert informing operators of the role that the main propulsion lube oil system was found to have played in the 2015 sinking of U.S. cargo ship El Faro. All 33 crew on board died when the 790-foot El Faro sank close to the eye of Hurricane Joaquin near the Bahamas on October 1, 2015, while en route from Jacksonville, Fla. to Puerto Rico. Loss of propulsion during extremely heavy weather was revealed as a major contributing factor to the vessel’s sinking, according to The Coast Guard Marine Board Report on the incident.

Inland Workboats Have Much to Gain from Diesel Electric Propulsion

Diesel electric technology, as part of a comprehensive engineering design process, should be considered by the inland towboat sector. Diesel electric propulsion is not a new concept. Like azimuthing drives, its application to the inland marine market has lagged behind other areas of the marine industry. Diesel electric has gained traction in industries where fuel economy and redundancy of propulsion systems for safety is paramount. In particular, vessels like passenger ferries and offshore supply vessels have enjoyed the benefits of the diesel electric systems.

In its investigation report, the Transportation Safety Board of Canada (TSB) found that inadequate vessel maintenance and voyage planning guided by an underqualified crew led to the January 2017 grounding of the bunkering tanker Arca 1 near Sydney, Nova Scotia. There were no injuries to the six people on board and there was no pollution. On 8 January 2017, while being delivered to Mexico from Sorel, Quebec, the bunkering tanker Arca 1 went aground in Little Pond, Nova Scotia in heavy weather while under reduced propulsion due to a failure of the port propulsion clutch.

Best Workboats of 2017

Harley Marine Services

Marine News showcases the best of North America’s 2017 workboat deliveries. There is something for everyone. Notwithstanding the lingering offshore energy downturn, there were plenty of bright spots for North American shipyards in 2017. If a hull was delivered in 2017, we took a look at it, with several areas as a focus for inclusion into this edition. For starters, it is always exciting when a domestic yard delivers a vessel – or multiple vessels, for that matter – to foreign buyers. We can compete in a foreign arena; on price, quality and on-time delivery. This year was no different.
