Cortec has developed the next generation of VpCI fuel additives for more potent corrosion protection of fuel systems. Cortec VpCI-707 has been specially formulated to protect fuel tanks and systems from corrosion and sludge formation without damaging copper and aluminum. It is an option for keeping new and existing fuel tanks and systems in good condition during day-to-day operation and especially during vulnerable times such as intermittent operation, storage, or shipment. Other benefits of VpCI-707 are its improved water handling and good injector-cleaning capabilities.

Marine Coatings: Polyflake Protects against Corrosion

Photo: Polyflake

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

(Photo Source: ThinkStock)

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.

SCHOTTEL's New ProAnode Goes to Market

The new position in the tail of the nozzle not only shields the anodes, but also offers additional operational potential as it contributes to the optimal hydrodynamic flow of the nozzle. (Photo: SCHOTTEL)

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…
