Tech File: Boiler Tech for LNG Propulsion
With the projected increased adoption of LNG as a fuel in the marine sector, Alfa Laval plays a key role with its tech an knowledge in the area of boilers, which enables ships to deal with boil-off gas (BOG). Specifically, Alfa Laval’s dual-fuel boilers, Gas Combustion Unit (GCU) and services effectively form a portfolio of solutions for BOG safety.To use LNG as fuel, vessels must be able to manage boil-off gas (BOG), the evaporated gas that can increase tank pressure. Alfa Laval has long experience in BOG management on LNG carriers…

Learn to Weld with a Virtual Personal Trainer
The Fohnsdorf Training Center is located in Styria, Austria. To train welders, it uses a virtual welding system – the Virtual Welding simulator from Fronius, the Austrian technology leader. The simulator employs a virtual trainer to provide 1:1 training for the center’s students, an approach that has a positive impact on training quality.A young student carefully guides the welding torch. The weaving motions she makes as she welds the single-V butt weld in front of her appear very composed, an impression that is confirmed by the consistently positive feedback from her trainer.

New Shuttle Tanker Design for Teekay
A new shuttle tanker concept developed by the world’s largest shuttle tanker services provider, Teekay, will offer a new level of innovation, says Wärtsilä, whose smart technology solutions will be featured on the new vessels. To date, Teekay has ordered four of these ‘next generation’ ships, each to be built at the Samsung Heavy Industries (SHI) yard in South Korea. According to Wärtsilä, the newbuilds will feature a broad assortment of its latest technology innovations, all of which are central to the concept’s overall performance gains.
Shuttle Tankers - Safe, Flexible, Efficient
Shuttle tankers are an alternative to subsea pipelines. Typically for large water depths. For harsh weather operation the use of shuttle tankers is a necessity. DNV GL has incorporated the latest findings related to their design, operation and safety in an updated shuttle tanker paper. Shuttle tankers transport crude oil from offshore oil fields to terminals where use of subsea pipelines are not feasible. Major deployment areas include the North Sea and the Brazilian offshore fields. The global fleet has been growing steadily for decades, comprising 88 ships by the end of 2016.
FPSOs: New Storage Tank Explosion Frequencies
The fatal explosion in the pump room on the Brazilian FPSO Cidade de São Mateus in February 2015, demonstrated the potential for major accidents on this type of unit. Although there has never been an explosion in the oil storage tanks of an FPSO, there is a potential for such an event and offshore operators should assess the risks of such events to design against them. It is therefore imperative that risk assessments of FPSOs address this type of event. For this, they need to estimate its annual likelihood of occurring.
New BWTS for Big Bulk Carriers
U.K.-based ballast water treatment systems (BWTS) manufacturer Coldharbour Marine has launched a new treatment process designed specifically for large dry bulk vessels and ore carriers. The system uses the company’s existing inert gas based GLDTM treatment plant to meet the needs of large bulk carriers, which often ship large volumes of ballast water in upper wing tanks and discharge it directly into the sea. The IMO International Convention for the Control and Management of Ships'…
Inert Gas Systems Produces Significant Fuel Savings
The Alfa Laval Automatic Fuel Efficiency Module (AFEM) is a new modification for reducing the fuel consumption of Alfa Laval Smit Combustion inert gas systems. It does so by ensuring the inert gas that keeps cargo safe during offloading is only generated in the exact amounts required. In a two-year pilot project, the AFEM allowed Italian shipping company Navigazione Montanari S.p.A. to achieve an average fuel savings of 30 percent. Based in Fano on the Adriatic Sea, Navigazione Montanari owns and manages a fleet of 21 tankers.
