National Transportation Safety Board (NTSB) investigators identified communication failures and poor coordination between the master and pilot while docking the 1,080-foot ship. As a result, the maneuver itself, conducted with two tugboats, went badly awry.
“There was a point in the maneuver when both the tugboats and the (ship’s) thrusters were in opposition to each other’s actions, demonstrating the lack of coordination between the master and the pilot, beginning with the master/ pilot exchange and continuing throughout the docking evolution,” the NTSB said in its accident report.
The allision happened Feb. 12, 2019, at about 1730 as the ship approached Pier 3 in San Juan. There were 6,023 passengers and crew aboard. No injuries were reported, and there was no pollution.
Norwegian Epic diverted to San Juan after suffering problems with its hybrid propulsion system while en route to Tortola. The system consists of diesel engines generating electricity for 32,184-hp electric shaft motors turning the port and starboard propellers. The motor driving the port propeller lost half its power two days before the pier strike, and a day before it lost all power. Crew locked it at sea to avoid damage to the turning gear, the NTSB said.

Piracy edges closer to home with wave of raids in southern Gulf
In the brief cellphone video recorded by a crewmember on the offshore supply vessel (OSV) Remas, the pirates walk back and forth on the deck of the ship, clenching their guns and using them to point as they order around the crew. Their faces are draped in clothing and bandanas.

IMO emissions report raises new concerns about methane slip
A recent report from the International Maritime Organization (IMO) reveals that global shipping emissions increased nearly 10 percent from 2012 to 2018, with the industry facing a growing challenge concerning methane slip.
Bay State brothers find industry niche by making old into new
Zero non-conformities is what you want to hear when the U.S. Coast Guard inspects your tugboat. Once you’ve prepared your vessel, the inspectors come aboard to peruse your paperwork. They ask you pointed questions, to which they expect straightforward answers. Perusal completed, they then scrutinize all of the related safety systems, from bilge to antennas — even the ship’s bell.

Analysis points to faulty loading, low ballast in Golden Ray rollover
While the salvage of the sunken vehicle carrier Golden Ray has been delayed for months due to COVID-19 and the hurricane season, analysis by the U.S. Coast Guard has determined a possible cause for the rollover: a combination of vehicles placed too high on the ship’s decks, and not enough ballast water gave the placement of the cargo.
Seastreak newcomer pushing through dip in demand
Two years ago, Seastreak LLC took delivery of Seastreak Commodore, a 600-passenger fast ferry, from Gulf Craft of Franklin, La. Designed by Australia-based Incat Crowther, the vessel is the largest of its kind in the United States and was built to meet the burgeoning demand for service in the New York-New Jersey market.

Advanced props, rudders provide new efficiencies below the waterline
It took a decade or two from the invention of the marine propeller in the 19th century for the technology to become widely accepted. Thereafter, adoption has been nearly universal, but progress toward improved efficiencies has come in fits and starts.
