Wärtsilä EnergoProFin for CPP, FPP

Wärtsilä EnergoProFin is a state-of-the-art energy saving solution that increases propeller efficiency and creates fuel savings of up to five percent. The solution is now available for both controllable pitch propellers (CPP) as well as fixed pitch propellers (FPP), yielding the same results in both propeller options. Offering the solution for technologically more challenging CPPs was previously considered impossible in the industry, but is now made possible due to development work by the Wärtsilä hydrodynamics team.

Propeller Repairs Increase as Winter Approaches

Hydrex Underwater Technology has registered an increase in the number of vessels experiencing propeller damage. Dave Bleyenberg, Hydrex Production Executive, explained: “While winter months usually result in an increase in propeller repairs, this normally occurs between January and March. In November, a Hydrex team was called out to Taranto, Italy, to inspect a 27,500dwt general cargo ship, whose engineers had reported excessive vibration from its five blade, 5m diameter propeller as the vessel returned from operations. The cause of the vibration was two bent propeller blades.

Volvo Penta for Virginia Pilots Boats

The new boat being built for the Virginia Pilots Association joins the increasing number of pilot boats powered by Volvo Penta IPS. The 55-ft. vessel, designed by C. Raymond Hunt Associates and built by Gladding-Hearn Shipbuilding, will run on twin D13 900 hp U.S. EPA Tier 3 engines with IPS3 drives. “Stability, reliability, support, speed and efficiency – these are the five criteria that we used to select the engine for the new pilot boat,” said Frank Rabena, a 17-year pilot and chairman of the Association’s pilot boat committee.
