In cooperation with R. Allan Ltd. (RAL) and Novatug B.V., Voith participated in the development of a new tug. The Carrousel RAVE Tug (CRT) is characterized by a towing winch on a ring. This ring can rotate freely around the tug's deckhouse – a unit referred to as the "Carrousel Towing System". This system eliminates the risk of capsizing under a tow load. In combination with two Voith Schneider Propellers (VSPs) arranged in-line, the tug design allows for a slender and highly efficient hull. New and previously unseen levels of tug operation safety and efficiency will be reached with this evolutionary concept. The first two Carrousel RAVE Tugs are currently under construction for Novatug B.V., a subsidiary of Multraship Towage & Salvage.

Mexico’s state-owned petroleum company PEMEX (Petróleos Mexicanos) invests in a modern tug fleet. Voith was awarded to supply the propulsion for nine new Voith Water Tractors (VWT) which are to enhance the safety of oil tankers entering and clearing port at several terminals as of 2016. During an extensive selection process, the vessels powered by two Voith Schneider Propellers (VSP) stood out with regard to their low susceptibility to debris. The Spanish Shipyard ARMON (Astilleros Armón) will provide the project with it’s own in-house design using VWT configuration, project management, technical advice on location and the supply of all main equipment.

Are shipowners prepared to enter SECA zones? Due to existing regulations on air exhaust emissions from the International Maritime Organization (IMO), and with the European Union working towards an alignment with IMO MARPOL Annex VI, the marine industry will need to choose a path on how to achieve compliance, a choice that will have tremendous impact on shipping. Legislation has already had an effect on the fuel markets in regulated areas, as fuel prices are expected to increase even further in 2015 when the 0.1% fuel sulfur limit enters into force.
