Subsea Industries develops durable, non-toxic hard hull coating systems. Ecospeed was the first coating and was launched in 2002, but since then a line of other products has been added.EcoshieldEcoshield is an enhanced version of Ecospeed. Small but significant variations of the Ecospeed formula have been tested on rudders since 2002 with extraordinary results. After years of testing (initially under the name Ecospeed Strong) the product was launched in 2013.Ecoshield is designed to protect rudders and other underwater running gear against the cavitation phenomenon: against pitting…

The biocide-free anti-fouling film, RENOLIT DOLPHIN S is already well established in in shipping industry. As a biocide-free alternative to anti-fouling paints, this product sets new standards. Further practical trials have now shown that this film could be suitable for other fields of application.In April 2018, the German Waterways and Shipping Authority (WSA) in Bremerhaven decided to test this film solution from RENOLIT. “I found out about the film in an article and wondered if this wouldn’t be a good solution to the fouling of our fairway buoys.

Marine Coatings: Polyflake Protects against Corrosion

Corrosion starts from the inside out. The alkali that neutralizes acid water - and the acid water produced in a gas scrubbing system - are corrosive. Containment surfaces resistant to both alkali, acid water and their combination provide a safer ship with less expensive maintenance. While selecting metal alloys as more resistant to either acid or to alkali, facing all conditions simultaneously is problematic, as temperature plays an important role in pitting corrosion.Ultimately…

A 10-tug build project leads to federal standard color update for Great Lakes Towing Company.Attention to detail enables uniformity. And when you’re refreshing a renowned tugboat fleet with a 117-year history, you want to ensure a uniform look across all vessels to portray a strong brand image. Doing so means achieving uniform coloring throughout the fleet. It also means having uniform colors on each vessel between dry dockings – such that maintenance coatings don’t stand out…

New EAL Grease for ATB Couplings

Specialty lubricants manufacturer Klϋber Lubrication recently introduced a new environmentally acceptable lubricant (EAL) grease for articulated tug and barge (ATB) couplings, Klüberbio AM 12-501.Klüberbio AM 12-501 is an adhesive EAL grease designed specifically for the large plain bearings, rams and connectors used in ATB coupling systems.

The remarkable success of autonomous and remotely-controlled vehicles on land and in the air and the interest in this technology being shown within maritime circles suggests that it is only a matter of time before autonomous ships are deployed at sea. Although the fuel costs represent, by far, the majority of shipping costs compared to onboard crews, there are yet substantial benefits to be reaped from autonomous ships. The potential economic benefits are too great to ignore this emerging technology.

All Operators Should Follow These Lubrication Steps

Maintaining mission-critical winches, windlasses and cranes: the four must-have lubrication steps that all operators need to keep gears going. In the marine industry, winches, windlasses and cranes are the work horses of deck and harbor operations. They can be used to set anchors, position floating drill rigs, raise and lower sensitive scientific equipment, tow a ship, load/unload heavy cargo or even land fish. They are as vital to the mission of a vessel or a port as the main engine is to a ship.

Deck Machinery: Five Stress Areas

When you face various deck equipment challenges, making the right lubricant selection can help lower labor costs, extend the life of the equipment, improve safety and more. The key is to identify deck equipment stresses, then apply the optimum lubricant solution. A trained lubricant specialist has the knowledge to relieve problems and significantly lower your total operating costs. That’s because selecting a specialty lubricant that can maximize the performance of a given deck application brings many benefits…

The first SCHOTTEL Rudderpropeller with the newly developed and patented ProAnode has left the German factory in Doerth. According to the manufacturer, ProAnode’s new form and position sets higher standards in corrosion protection, thereby extending the lifecycle of the thruster. Furthermore, moving the position of the anode from the outside surface into the cross-section of the nozzle tail leads to subsequent operational benefits, such as reduced flow interference, resulting in fuel savings.

There has been little reaction by way of statements or position papers from marine fuel lubricant manufacturers to the IMO MEPC70 proposals for a global fuel sulfur content cap of 0.5 percent by 2020 but they are fully aware of the implications of the proposed regulations and are taking what could be termed a ‘pragmatic approach’ to fuel regulation compliance. Marine lubricant suppliers have avoided getting involved in the debate as to whether the IMO MEPC70 proposals to reduce permissible marine fuel sulfur content to 0.5 percent or less is good…

New Cylinder Lubricant: Shell Alexia 140

Shell Marine has shared an insight into the approach driving its work to protect modern ultra-efficient diesel engines against cold corrosion while still optimizing cylinder oil feed rates, across the entire range of vessel operating conditions. The company said it has been working closely with major OEMs and several ship owners who support this development. Following formulation and laboratory testing in 2015, the new Shell Alexia 140 has ondergoe over six months of shipboard trials with a Shell Marine customer. “We are responding rapidly to the changing needs of the industry, helping our customers to cope with their full range of operating conditions,” said Jan Toschka, General Manager of Shell Marine. “This latest development underpins our commitment to the industry and its future.

Not All EALs are Created Equal

What is an EAL? Environmentally Acceptable Lubricants (EALs) are defined by the EPA as offering these three characteristics. First, they must be “biodegradable” - biodegrading into carbon dioxide and water by ≥ 60% or more within 28 days (according to OECD 301B or ASTM D7373 methods). Next, they must be “minimally toxic,” causing only a light impact on the aquatic environment (LC50> 100mg/L for lubricants and LC50>1000mg/L). Lastly, they are “not bioaccumulative,” and must have a low propensity to bioaccumulate in organisms.
