SCHOTTEL said it has delivered propulsion units for nine more newly built cargo vessels. Each of the carriers, designed by the Russian company Marine Engineering Bureau, is equipped with two rudder propellers from the German propulsion systems manufacturer.The main propulsion of the multipurpose dry cargo vessels consists of a pair of diesel-driven SCHOTTEL RudderPropellers type SRP 340, each with an input power of 1,200 kilowatts at 1,000 revolutions per minute. With this thruster configurationā€¦

The shipping industry risks investing billions of dollars on vessel optimization services that fail to deliver on overall operational efficiency and performance due to a lack of understanding and appreciation of weather which accounts for 80 percent of the impact on vessel performance warns voyage intelligence and insight specialist StratumFive.As vessel performance optimization becomes increasingly more sophisticated, ship owners and operators have access to a far broader range of technologies, datasets and potential avenues for optimization than ever before.

Was the closing of the Houston Ship Channel for over three days in March 2015 due to the use of Ultra Low Sulphur Fuel Oil (ULSFO)? After reviewing the testimony, and evidentiary material presented by the National Transportation Safety Board (NTSB) regarding the 2015 Conti Peridotā€™s collision with the Carla Maersk, it is the authors' opinion the report fails to address significant contributing factors. The NTSB has overlooked a serious threat to vessel operations throughout the world.

Foreship: New CFD Methodology

In the quest to model real conditions faced by ships at sea for design purposes, earlier this summer Foreship unveiled details of a live project that has factored real sea states into CFD-based hull form optimization. The company reports that the results of ā€˜in waveā€™ analysis had confounded expectations, leading to a design decision contrary to those informed by conventional model testing. The project involved a modelled comparison of two different bow sections for a newbuild cruise ship, a project focused on optimizing the shipā€™s resistance in waves.

MHI Installs MALS (Mitsubishi Air Lubrication System)

MALS Concept Sketch: Air bubbles covering the vessel's bottom, like a carpet of air.

For First Time and Verifies Over 5% Fuel Efficiency Improvement - Sights On Expanded System Applications to High-speed, Slender Hull-form Ships. Mitsubishi Heavy Industries, Ltd. (MHI) has installed its innovative "Mitsubishi Air Lubrication System" (MALS) for the first time on a ferry - a ship with a slender hull form* - and confirmed over 5% improvement in fuel consumption. MALS is MHI's proprietary technology that reduces frictional resistance between the ship hull and seawater by introducing a layer of air bubbles blown from the ship's bottom.

Technology Associates, Inc (TAI) a New Orleans based Naval Architecture firm which also has an office in India has unveiled its Technology EnviroMax 300 OSV. Utilizing a unique Designer/Builder relationship, this design was developed in conjunction with Thomaā€Sea Shipyards. The design already has up to six vessels under construction at Thomaā€Sea Shipyardsā€™ facilities in Lockport, Laa. Thomaā€ Sea Shipyards acquired this facility from Halter Marine in 2002 and has been using it to build OSVā€™s up to 270ft.

Feature: Queen Mary 2 New Technology Melded to the North Atlantic Tradition

Confounding the skeptics who said the 70,300-gt Queen Elizabeth 2 would be the last transatlantic liner ever built, the 150,000-gt Queen Mary 2 is set to make her service debut in January 2004, signifying a $780-million investment in a luxury passenger ship structurally engineered for the North Atlantic. Destined to uphold and revitalize the Cunard liner tradition, the 30-knot QM2 will break new ground in passenger ship technology, while incorporating lessons learned with the 1969-commissioned QE2. The challenge of fulfilling an extremely tough schedule in a notoriously harsh environment, and of meeting rising customer expectations as to service quality, comfort and reliability in all conditions, permeates every aspect of the technical design.
