Spending More Time at Sea
Margins are tight for vessels that operate offshore or in coastal waters. Take the global offshore support vessel (OSV) market for example, it looks set to be yet another challenging year which has concerned senior executives preparing for a sixth year of downturn. Many had hoped that 2019 would be the year that marked a turning point in OSV fortunes, but the uptick hasn’t materialized, and there is renewed anxiety about what could potentially be the worst market since the 1980s.It…

Subsea Robots in the Splash Zone
From their base deep within a former World War II U-boat pen, Norwegian outfit, OceanTech, is developing a set of robot tools that cling to offshore structures in order to effect inspection, maintenance and repair, or IMR. Old submarine anchorages are now subsea testing and training sites, but the North Sea is still the target. Hundreds of aging platforms and subsea structures require IMR that’s too costly, complex or hazardous for divers or remotely operated vehicles, or ROVs.As he walks us through Dora II…
Scrubber Corrosion: Addressing the Issues
A focused Q&A with M.Sc. Chem. Eng. Anders M. Sørheim, Yara Marine TechnologiesHow important is material quality when selecting a scrubber system?If the intention of a scrubber installation is to operate the scrubber for the lifetime of the vessel, assuming a minimum of 10 years, then the material quality is imperative. A study performed by the American stainless-steel manufacturer ATI titled “Evaluation of Alloys for Marine Exhaust Scrubbers – Effect of Welding and a Crevice” confirmed the importance of correct material choice for scrubbers.
Golden Boats Lifts Enhances Sea-Drive
In over 20,000 Golden Sea-Drives manufactured, not one has ever failed. While most companies would rest on their laurels with such an impressive statistic, Golden Boat Lifts didn't.

Austal, Fred. Olsen Partner on Trimarans
Australian-based global ship building company Austal and the UK-based, Norwegian-owned cruise shipping line Fred. Olsen have partnered on two next generation trimarans with advanced environmental credentials.Starting with the design process, Austal’s R&D team used optimized lightweight structures and the benefits of Austal’s ongoing weight reduction program to reduce the power required to achieve the vessel’s high speed.This results in significantly lower emissions from the main engines compared to a steel vessel equivalent.
Exceptional (Market) Reach Lifts a Crane Retrofit to Success
The New York State Canal System, Advance Marine and MelCal Cranes all enjoy a reputation for versatile applications in challenging conditions. It’s no wonder that their recent deal to replace an aging maintenance crane was also a similarly good fit.When Advance Marine recently delivered a telescopic boom crane to New York State Canals, the decision regarding which type and brand of crane to select wasn’t made in a vacuum, nor was it made lightly. That’s because commercial utilization of America’s original superhighway – the Erie Canal – is on the rise again.

Fuels, Lubricants & Green Marine
International Maritime Organization (IMO) fuel rules entering force in 2020 mandate a drastic sulfur reduction. By 2050 the mandate is to cut greenhouse gas emissions of shipping by at least 50 percent.Marine fuels, lubricants and additives manufacturers play their part in establishing maritime’s green credentials by introducing new environmentally acceptable technologies and products.The shipping industry is more than ever portrayed in a bad light due to increasing awareness of its contribution to global climate change, according to Dirk Kronmeijer, CEO of GoodFuels Marine.
Anti-Fouling Film Tested on Fairway Buoys
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…

Corrosion Control and the Autonomous Ship
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.
