The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.

Mitsui O.S.K. Lines has announced that its group company MOL Techno-Trade will start selling an upgraded version of its energy-saving Propeller Boss Cap Fins (PBCF). MOL Techno-Trade has sold more than 3,100 PBCFs to ship owners all over the world. The new type of PBCF was jointly developed by MOL, Akishima Laboratories (Mitsui Zosen), and MOL Techno-Trade. The new design enhances propeller thrust and reduces torque thanks to refinements in fin shape and height. Tests of the new type PBCF on vessels in service confirmed an energy savings of around 5% compared to sister vessels not equipped with PBCF. The previous design showed an estimated 3% energy savings. The new PBCF design has already been patented around the world.

The Vancouver Fraser Port Authority’s EcoAction Program offers discounted harbour due rate to vessels that have implemented voluntary emission reduction measures and other environmental practices. As of January 1, 2017, vessels equipped with PBCF and transiting to the Port of Vancouver will be eligible for bronze level recognition and a 23% discount in harbour dues.

Hull Vane on New Patrol Vessel for Port of Rotterdam Shipyard Kooiman recently started building a new 25-meter patrol vessel for the Rotterdam Port Authority. The vessel will be delivered in the summer of 2017. The order followed a public tender process in which several shipbuilders competed with their designs. The design incorporates several innovations to improve the efficiency. Public tender The principal focal points in the tender were the vessel’s complete life-cycle costs, a minimal amount of emissions and a minimum of wave formation.

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. The Wärtsilä EnergoProFin is a specially designed propeller cap with hydrofoil section fins on the downstream side of the propeller. It is an innovative energy saving device that can significantly reduce a vessel's fuel consumption as well as its emission levels.

Using Computational Fluid Dynamics (CFD), new insights can be obtained into the working principles of Energy Saving Devices (ESDs), which all serve to increase the fuel efficiency of a ship. The advantages of using ReFRESCO to study ESDs are explored in this article. The capability of simulating different moving objects, and their interaction in on calculation (applying the so-called Sliding Interfaces Technique) has increased the range of applications of the viscousflow CFD code ReFRESCO.

Last month Hydrex installed  Propeller Boss Cap Fins (PBCF) on two tankers during their respective stops in Ghent and Antwerp. As a result of the underwater operation, the ships will not have to wait for their next drydock visit to start benefitting from the fuel savings the PBCF’s will bring them. The Propeller Boss Cap Fins (PBCF) is a device for propeller efficiency improvement developed by Mitsui O. S. K. Lines, Ltd. The PBCF can recover energy loss of a propeller hub vortex in the propeller’s backward flow.

Belgium's Euronav reported a net loss of US$ 31-million in its Q4 2012 financial report. The result of the fourth quarter is affected positively by the revaluation at marked-to-market levels of non cash items (unrealized) such as hedge instruments on interest rates for a total of US$ 600,000. After successfully implementing a strict slow and super slow steaming policy whenever possible, Euronav continues to apply measures to reduce fuel consumption across its spot fleet. The company has already retrofitted a VLCC, with a Mewis Duct, improving propeller efficiency, which demonstrated to be the most efficient energy saving device. The same retrofitting will be done on at least 4 Suezmax vessels this year.
