    Basic Principles of Ship Propulsion
    For the purpose of this paper, the term “ship” is used to denote a vehicle employed to transport goods and persons from one point to another over water. Ship propulsion normally occurs with the help of a propeller, which is the term most widely used in English, although the word “screw” is sometimes seen, inter alia in combinations such as a “twin-screw” propulsion plant.

    Costs and Benefits of LNG
    The use of liquefied natural gas (LNG) as ship fuel has recently gained more attention in Europe, but also in Asia and the USA. There are three visible drivers which, taken together, make LNG as ship fuel one of the most promising new technologies for shipping.

    Engine Management
    The world has enormous quantities of natural gas, but much of it is located in areas far from where the gas is needed. To move this environmentally friendly fuel across great distances, across oceans, natural gas must be converted into liquefied natural gas (LNG). Shipping is a vital component in any LNG supply train. But an LNG project’s shipping could simply be considered as a floating pipeline for the transportation of LNG, therefore LNG shipping is normally considered in the long term.

    Ice Classed Ships
    Many merchant ship types are built for a given ice class notation which depends on the classification society and on the ice form and thickness during winter operation. Building a ship for an ice class for winterisation means for example that the hull has to be thicker with stronger girders, beams and bulkheads which, of course again, depend on the degree of ice class.

    MAN B&W Dual Fuel Engines - Starting a new Era in Shipping
    The need for seaborne transportation will increase significantly in the years to come. At the same time, the heavy fuel oil (HFO) price is increasing, stricter emission requirements are coming into force and the public is becoming more concerned about the environmental footprint of shipping. As a result, the industry is investigating in alternative fuels for shipping. Liquefied natural gas (LNG) is an attractive option and is expected to be cheaper than fuel oil in the future.

    ME-GI Gas-ready
    Given the volatile nature of today’s fuel prices combined with the introduction of a more stringent emission regulation in emission control areas, it has never been more difficult to mitigate the economic risk associated with operating a vessel.

    Propulsion of VLCC
    This paper evaluates the options when selecting an engine for a VLCC (very large crude carrier) on the basis of vessel speed, propeller diameter and CO2 emissions. The influence of the various parameters is illustarted by two case studies.

    Propulsion Trends in LNG
    Natural gas is a “clean” fuel compared to diesel and heavy fuel oil and, together with an increasing environmental responsibility, there is a rising demand for natural gas worldwide. Where it is not possible to transport natural gas by means of pipelines, the LNG (Liquid Natural Gas) carriers have to take over the transportation because natural gas in liquid form at atmospheric pressure only takes up 1/600 of the natural gas volume.

    Service Experience
    A high number of G-type and S-type engines of the latest generation have entered service successfully. These engines are generally characterised by Tier II compliance, heavily derated layouts and performance with main focus on part and low-load fuel optimisation. Very close to 100% of these engines are of the electronically controlled ME-C and ME-B types.

    The Dynamic Limiter Function
    The dynamic limiter function (DLF) is a new engine control system functionality that has been developed to improve engine and ship acceleration. This paper describes some principles of ship acceleration and why MAN Diesel & Turbo has chosen to develop DLF and how DLF works.

    Using Methanol Fuel in the MAN B&W ME-LGI Series
    Methanol as a ship fuel is interesting for ship operators because it does not contain sulphur and is liquid in ambient air conditions which makes it easy to store on board ships. So for ships operating in International Maritime Organization (IMO) emission control areas (ECA), methanol could be a feasible solution to meet sulphur requirements.
