Meeting a growing need for ship collision safety
Chalmers University of Technology: The trend in worldwide shipping is that total freight at sea is growing and that its role in the logistic transport chain of many types of cargoes is indispensable. Accordingly, the number of ships at sea and the sizes of them are increasing continuously. As a result, the risk of collision between vessels has increased, in particular for short sea shipping close to shore, where sea-traffic density is high and the sea routes may be narrow.

Rogue waves: Fiction and facts
Umeå University: Rogue waves, extreme ocean waves with heights up to 30 metres, have been common elements in stories from people working at sea, as well as in popular fiction. But what is really fact and what is fiction when it comes to these ‘monster’ waves? Here, I will give a short overview of what we know today about such waves.
Anchor handling simulation
MARIN: Anchor handling simulation is a relatively new area where simulation technology is being stretched to new boundaries to provide high-quality training value for offshore-related operations such as anchor handling and towing. Crucial elements that are addressed are safety issues and typical operations, ship modelling, seakeeping, heavy (external) force modules, catenary systems, 3D modelling, DP systems, and animation and visualization technologies.
New system optimises performance in waves
Amarcon: Amarcon is specialized in ship and offshore hydromechanics and ship performance predictions in waves. Using this expertise, the cooperation with leading players in the maritime industry and a highly experienced software development team, Amarcon bridges the gap between fundamental research and daily ship- and offshore operation practice. This resulted in the monitoring and routing products Octopus Office and Octopus Onboard.

New ways to capture, store and reuse schematic data
Aveva: As shipbuilding projects become ever larger, they increasingly need to employ multiple contractors in different locations, using a variety of engineering software. Because of this, consolidating and managing schematic data from multiple sources becomes essential.
Developments within maritime communication
Telemar: Ten years ago only the most modern and forward thinking shipping companies equipped their vessels with PC to handle certain functions on board. Today one can find PC’s, often in networks, on board virtually any kind of vessels, from fishing vessels to VLCC. They are used for ships and crew accounting, purchasing, stock control, maintenance planning and voyage planning. Another prime use of PC’s are in connection with communication between ship and shore.

New Arctic routes in the tracks of climate change
WMU: Although it is commonly known that climate change has some cons, it may also carry some benefits. Opening the Northern sea routes in the Arctic Ocean for navigation may be one of the consequences of climate change that may increase the possibilities of using it in navigation for longer periods without ice breaking assistance.
The International Load Line Convention: Enhancing safety at sea
WMU: IMO has laid great emphasis on the safety of ships, contributing towards facilitation of the ship as a safe working platform for its crew. The same is reflected in the various conventions in force. The International Convention on Load Line (ICLL),1966, facilitates the requirements for safe ships, through its objective by ensuring buoyancy, adequate reserve buoyancy, water integrity, hull strength and stability. In addition to ICLL other convention fostering objectives of safer ships are SOLAS, MARPOL, UNCLOS, ISM and STCW. This article will discuss how safety at sea has been enhanced by the ICLL and how different conventions are complementing the ICLL. Furthermore, including operational matters as a prerequisite to the conventions can further foster greater degree of safety at sea.

New technology revolutionizes winter shipping
Aker Arctic: Aker Arctic is a unique player in designing ships for navigating in ice and/or breaking through it. Comprehensive new ice model testing facilities and decades of field data give its designers a very good understanding of the problems involved – and have led to a number of landmark technologies, such as the double-acting tankers Vasily Dinkov and Michail Ulyanov and the container carrier Norilskiy Nickel.

Optimised port and fairway design by simulations
SSPA: Every transport system has its bottlenecks. Aeroplanes cannot touch down because the airport has too limited capacity. The number of trains is limited because of the mix of slow trains and rapid trains. And, in the maritime world, there are several bottlenecks. When today’s market calls for higher efficiency, i.e. less time spent in the harbour, the port administration sees no optimized fairways, no optimized port facilities and no optimised terminals. The main challenge here is, on the one hand, to improve efficiency and, on the other, to improve safety. Is there a discrepancy between the two or are they two sides of the same coin?
Organisms passing through a Wallenius AOT unit are exposed to radicals, which break down the cell membrane and render the organisms non-viable.
PureBallast: Approved and ready for the ballast water challenge
Alfa Laval/Wallenius: Alfa Laval’s PureBallast is one of only a handful of ballast water treatment systems with IMO approval – and the only one that neither requires nor generates chemicals.
The Ballast-Free Ship concept bulk carrier utilizes longitudinal ballast trunks open to the sea rather than conventional ballast tanks.
The Ballast-Free Ship concept:
An alternative solution to ballast water treatment
University of Michigan: Rather than treat ballast water with onboard treatment equipment, The Ballast-Free Ship concept reconfigures the vessel to create a slow, continuous flow of local seawater through longitudinal ballast water trunks, essentially eliminating the movement of ballast water from one part of the world to another.
The USNS Gordon is one of about 20 vessels developed for the so called Sealift programme in the US Navy. The vessel has been equipped by MacGregor with all ramps, hatch covers, cranes, bulkhead doors and similar ro-ro equipment. The vessels will operate in combination with a smaller type of vessel that will receive and carry the cargo closer to shore.
Digital prototypes in live projects
Epsilon: Digital prototyping, and in particular the capability for dynamic simulation, has become a success factor for MacGregor ro-ro division. One outcome of the company’s technical ambitions is the work on digital prototypes in live projects. Using simulations in a digital environment, e.g. during optimization and, if necessary, troubleshooting, MacGregor aims to avoid the difficult and often time-consuming trial-and-error work on board.

Concluding the most probable sinking scenario of MV Estonia
SSPA: On 28th September 1994 the Estonian-flagged ro-ro passenger ship MV Estonia, having departed from Tallinn with 989 people onboard for a scheduled voyage to Stockholm, sank rapidly, stern first, and disappeared from the radar screens of ships in the area at about 01.50 hours. There were 852 fatalities and 137 survivors. The accident is considered to be the worst disaster at sea in post-war Europe. The SSPA Consortium can now present the final report of the research study of the sinking sequence of MV Estonia.
The M/T Helene Knutsen, sailing out of Skarholmen, Norway, has successfully undergone MAN Diesel PrimeServ’s emissions service, which introduced slide valves to reduce NOx emissions and smoke.
Emission service in the future
MAN Diesel: MAN Diesel PrimeServ is building up its organisation so as to be capable of installing plant after treatment systems and performing emission optimisation. As part of this process, it aims to work across borders with different PrimeServ service centres in different countries, in both the two- and fourstroke business areas. This will ensure the capacity of PrimeServ to provide emission services, both today and in the future.
