New functions for the autonomous ship
The KISS principle will also be applied to the ship itself and it is also important to look at how existing vessels can be modified to support unmanned operation. At the hardware level, technical modifications will be necessary, for example to the fuel-processing system, while an electric-powered water-jet for back-up propulsion and steering may have to be retrofitted.New sensors to replace the look-out are also an important part of the unmanned ship. A combination of high resolution radar, low-Iight and infrared cameras form the 'advanced sensor system'. Most of the technology involved is already available and its adoption would be more a question of cost than of general availability. The sensor-system will be integrated with more conventional equipment such as the AIS system and ARPA radar. Computer-based data fusion, using Information from the various sensors, will further increase the capability of the sensor system. All these systems are alre... [More]

Home-based inventors, inspired to give real meaning to the much over-used word ‘innovation’, are burning the midnight oil in garage workshops and on kitchen tables all over the world, but very few of them stay the course to get a device patented and glimpse commercial opportunities on the horizon. One of the few is British inventor Martin Wickett who went on to found the small business WITT Energy (aided by his wife Marie) with aims to develop and capitalise on his ‘Whatever Input to Torsion Transfer’ (WITT) device.Energy from chaosThe WITT technology is capable of collecting chaotic motion in any direction clockwise, anti-clockwise, up and down and back and forth at any speed to turn a flywheel and create electricity. The system has numerous potential applications in the marine environment - sea, river or tidal - from lighting navigational buoys to GPS systems, or even the charging of a moored boat’s batteries. The size of the device can match the r... [More]
First results presented about MOL COMFORT’s sea damageReasons for the severe sea damage of the container vessel MOL COMFORT still not finally cleared.Together with both the Japanese classification society ClassNK and Mitsubishi Shipyard the shipping company Mitsui O.S.K Lines (MOL) currently investigates the disaster last summer where the 8.110 TEU-container carrier damaged in heavy sea and finally broke in two while underway from Singapore to Jeddah. The crew could escape in life rafts and were picked up by another vessel. Now preliminary results have been released.
Experts conclude, based on the very serious water ingress at the center part of the hull, that a crack in the ships bottom has been occurred. In the course of investigations on board the sister ships of the MOL COMFORT deformations of up to 20 mm have been detected. But there exist still not a clear statement if these deformations have been the reason for the water ingress. Because of this the shipping company, ship... [More]
At the recent international defence exhibition (DSEi) in London, a new lightweight diesel engine was on display from Cox Powertrain developed with Ricardo UK. The power dense of 300hp (224 kW)/4,000rpm is a 3.6 liter supercharged 2-stroke diesel engine, weighing 136 kg. The four cylinder, eight piston engine module features an opposed piston (OP) configuration and uses a Scotch Yoke cranking, saving weight and moving parts. A two module variant will produce 700+hp. Some variants may be able to deliver up to 900 hp. Beta testing will commence in 2014 with an estimated launch date for the outboard motor version in 2016.
It’s not a secret anymore that the shipping industry today is facing some serious challenges with respect to meeting upcoming exhaust gas emissions regulations. The contribution from shipping to sulphur oxide (SOx) and nitrogen oxide (NOx) emissions today is considerable, thus the need for reductions. Three main alternatives – switching to low-sulphur fuels, installing exhaust after-treatment devices, e.g. scrubbers, or using natural gas – have been investigated to some extent, but very little information is available on methanol as a marine fuel.Methanol is a clean fuelMethanol does not contain sulphur. Emissions of particulate matter and NOx from methanol combustion in marine engines are expected to be lower than those resulting from the combustion of conventional fuels. Methanol is widely available, can be safely transported and distributed using existing infrastructure, and in 2012 it is currently much cheaper than marine distillate fuel based on energy content.

In November 2011 Fassmer Shipyard, Germany, and Fugro N.V., Netherland, signed the contract for the new 40m „Fugro Helmert”, a new Offshore Survey Coastal Vessel for hydrographic and geotechnical tasks in worldwide operation. Fassmer was assigned to design and build the vessel in a time period of 20 months. The delivery is scheduled for August 2013.
On 8th of July 2013 the new Fugro Survey Vessel was christened by godmother Mrs. Irmgard Jeuken, in the presence of more than 140 guests, on the Fassmer Shipyard Berne. Directly after the naming ceremony the vessel was launched. During the following weeks all remaining works will be finished. On 8th of August 2013, after completion of all final tests and trials, the vessel will be handed over in time to Fugro.
This vessel is designed for worldwide operation, means well insulated against high temperatures, air conditioned and with a total accommodation for crew and guest of 20 persons. A maximum of 12 guests are allo... [More]
The deep water of Lake Kivu on the Congolese-Ruanda border contains large quantities of methane and carbon dioxide. The reserves of methane are estimated to be 65 km3 (65 billion cubic metres) and carbon dioxide reserve 255 km3. The methane is considered to be partly magmatic in origin, produced by microbial reduction of the volcanic carbon dioxide, and partly biogenic through the anaerobic reduction of dead algae and fish on the lake floor.
In the past the lake has erupted at irregular intervals, belching out these deadly gases. In 1986 a similar eruption at Lake Nyos in Cameroon killed 1.800 people – including some living as far as 25 km from the lake. With two million people living in the basin of the much larger Lake Kivu, this represents a mega-disaster waiting to happen.
But the methane gas also provides an accessible and renewable energy resource to the Kivu region, valued at tens of billions of dollars.
In collaboration with the US energy company Contour Glo... [More]
