ABS: Managing change from high sulphur to low sulphur
Ships entering SOx Emission Control Areas (SECA) that normally operate on high sulphur bunker fuels need to orchestrate the change to the specified low sulphur fuels in advance, so that the vessel is burning clean on entry into the area. Operators must also be able to demonstrate to the relevant authorities through appropriate documentation and records that they have complied with the low sulphur limits.

DNV: Effective short sea shipping and fleet renewal
The ability to compete effectively is a crucial issue for any shipping company at any point in time. Competitiveness in shipping is established by different means and initiatives over shorter and longer term periods. The mechanisms involved are not particularly different from other industries. In shipping as in other industries growth maximisation, market power improvement and an adequate risk spread works.

Force Technology: Risk evaluations in Swedish ports
When the Swedish Maritime Administration (SMA) wanted to develop a methodology for risk assessment that can be applied generally in Swedish ports, Force Technology was contacted.

Germanischer Lloyd:
More than old iron
The legislation on the recycling of ships will soon be tightened up – and it will affect not only the last shipowner in the chain. Companies who prepare themselves for the new situation in good time stand to save time and money.
Lloyd's Register: New IMO passenger ship safety requirements
The purpose of this article is to give an overview of the new statutory requirements for passenger ships that were the outcome of the proactive “Large Passenger Ship” initiative taken by the International Maritime Organisation (IMO) in 2000 to address concerns that increasing ship sizes and passenger numbers might increase risk to above acceptable levels.

MARIN: Five decades
of innovation
MARIN (the Maritime Research Institute Netherlands), celebrating its 75th anniversary, started the first investigations into passenger vessels in the middle of the previous century. During the last decades the size of the vessels, available power and requested service speeds have increased dramatically. This requires innovative hull form designs and extensive numerical and experimental research. This article takes a look at some of the highlights in the design of the passenger vessels and the development of improved hull forms.
Zoi Nikopoulou: NOx trade
in EU – prospects and benefits
for shipowners
This study examines and presents the risks, the economic benefits and the business opportunities expected to arise for ships, which will voluntarily participate in a nitrogen oxides trade (NOx) within the EU waters. It explores policy, legal, technical and economic issues in order to assess not only an idea but also to evaluate an investment.

The Fatigue Damage Sensor.
A novel way to measure structural fatigue
As ships become increasingly larger in size to meet ever-growing demand for more efficient and safe marine transport of goods around the world, new technical challenges continue to arise. Solutions are sought to design ships with longer service lives and to extend the service life of ships already in service.

Oceanic-Creations: Composite material opens new construction philosophy
Once upon a time … the Swedish Navy was building their ships with oakwood from the forests in Blekinge, a county in the south of Sweden. Over the years several major developments have occurred in both shipbuilding and material technologies, which replaced the wooden merchant ships. The wood has been replaced by steel and/or aluminium; the sails have been replaced, first by steam engines and later with diesel engines.
SSPA: Increase transport efficiency and reduce fuel costs
International and national legislation will impose ever more stringent requirements on marine transport. This, together with the fact that the fuel consumption over a ship’s lifetime has a major effect on its total life cycle cost and its environmental impact, drives shipping lines to constantly look for more efficient transport systems. Furthermore, stabilizing emissions of CO2 and providing safe and sustainable marine transportation are important to modern shipping. Hydrodynamic improvement of ship propulsion and development of lightweight ship constructions can thus make a significant contribution to increasing the competitiveness of transport systems at sea.
SSPA: Shallow water manoeuvring
SSPA Sweden AB has carried out a benchmark study on shallow water manoeuvring. The purpose of the project was to validate the continuous development of the in-house simulation software. Different methods to mathematically model the shallow water influence were studied and results from model tests and full scale trials were compared. The focus was on the difference of the manoeuvrability of ships in deep and shallow waters.

Htay Aung: The art of materials selection in ship construction
Myanmar, formerly known as Burma, has large mineral resources of iron, lead, copper, zinc, tin, tungsten, gold, silver, and gemstones; and considerable resources of oil and offshore natural gas. From the raw materials to finished steel production is round about 150,000 metric tons each year in Myanmar. The business of importing and exporting iron and steels with neighbouring countries is carried out by both government and private sectors. Myanmar has 20,760 sq. km of water area and the length of the coastline is about 1,950 km.

Wärtsilä: New concepts in ferry propulsion
The demand for lower bunkering costs and reduced greenhouse emissions have become two of the main drivers in the field of ferry design. In competing with other modes of transport, the existing well-proven solutions might not be the most effective. Wärtsilä is conducting continuous development to meet the need for lower power demand and fewer emissions. In striving for these goals, Wärtsilä has during recent years proposed a number of innovative propulsion solutions for ferries. The latest in this series of ferry propulsion development concepts, is presented herewith.
Wärtsilä: SOx scrubbing
of marine exhaust gases
New legislation governing SOx emissions of ships affects ship design and operation. If the vessel operates in areas where SOx emissions are controlled, compliance can be achieved by using low sulphur fuel, or by cleaning exhaust gases using SOx scrubbers, or by a combination of both. Wärtsilä has experience from developing and delivering SOx scrubbers for stationary diesel power plants, and has now produced feasibility studies for selected ship types. |
