The RApport 2400-series tug-boats developed by Robert Allan Ltd. have earned their keep around the world. Now, Crowley Maritime has put the first U.S.-built RApport 2500-series vessel to work in Los Angeles and Long Beach, the busiest container ports in the United States.
Crowley chartered the 6,008hp tug from Brusco Tug & Barge of Longview, Wash. Diversified Marine of Portland, Ore., built the vessel, originally named Noydena. It left the shipyard around April 1, 2020, before making its way to Los Angeles later in the spring. Crowley renamed it Hercules to honor an oceangoing Red Stack Fleet tugboat acquired in the early 1900s. The newbuild is the company’s first ship-assist tug equipped with Tier 4 propulsion.
The 82-by-40-foot Hercules has Caterpillar engines paired with Cat z-drives. The electric Markey hawser winch on the bow facilitates efficient ship handling, while the towing bitt on the stern provides some additional flexibility as work arises around the port.
“It is fuel-efficient, while also being able to handle the big tankers coming in, given it pulled 88 tons ahead and 86 astern,” said Porter Sesnon, general manager of ship assist and escort for Crowley Maritime. “It’s nimble and small enough to maneuver the containerships around both harbors.”
The RApport 2500 design evolved from Robert Allan Ltd.’s time-tested RApport series dating back almost a generation. The 2400-series tugs — themselves based on Cates-series tugs designed for C.H. Cates and Sons of North Vancouver, British Columbia, between the 1960s and 1980s — were among the first ASD tugs operating in North America. The vessels have a flush deck and small house, and are known for being nimble, responsive, cost effective and plenty capable.

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

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.
