Editorial: Maritime technology in progress
In this year’s edition of the Scandinavian Yearbook of Maritime Technology we will meet authors from many disciplines within the Shipping Community.

Finance and Insurance: Ever-cheaper money. All major shipping banks and quite a few smaller ones are more than willing to accommodate demands from quality owners for ever-cheaper money, but for how long.

The “Estonia” disaster from
an Estonian perspective. “Estonia” was the first large Estonian passenger ferry and became a symbol for the young nation. Here the SSG editor in Estonia, Madli Vitismann, gives us an Estonian perspective on the disaster that ten years ago claimed the lives of 852 people.

A revolution in ship building? Steel and light weight concrete sandwich construction may represent new opportunities for the ship builders and ship owners as well as being a step forward for everyone concerned with safety at sea.

Oil mist monitoring in the atmosphere. Atmospheric oil mist detection will be mandatory in the future and reliable detectors must complement double skin fuel pipes.

Alfa Laval and Benrad Ballast Water Treatment System. Even though the ballast water problem is one of the four greatest threats to the world's oceans, a solution has proven to be a difficult challange. A treatment system must be not only economical and effective but also safe and practical.

Pure broadband and Hybrid solutions During the first week of September the first Sealink Acess terminal was delivered on board the Swedish flagged chemical tanker “Bro Atland”.

Investigation of maritime helicopter operations. The complexity of helicopter flight dynamics in the separated flow behind the superstructure of a ship or oil platform requires investigations in the time domain.

The picture shows pressure contours on a submarine (generic model) with sail and rudders.

SSPA does more than model testing. By using Compututional Fluid Dynamics it is possible to automate the optimisation process.

Cargo lashing is a delicate matter. The simulation program Seaman is able to simulate the ships motions in any arbitrary seaway, considering the influence from both wind and waves.

A speedy approach to a new
hullform surface generation.
A new software application supports a way of creating an initial surface definition, then continuously refining it to match the requirements of the advancing design stages.

Extreme roll events in head seas.
The occurrence of parametric roll behaviour depends on several conditions. The probability that all conditions are right is small. However, parametric roll has caused significant damage on a container vessel and if it occurs, it can result in considerable
damage.

The ballast-free tanker. The simplest way to solve the problems connected with the
transportation of ballast water around the world is to create a ship independent of ballast water.

SPS – A stepchange in shiprepair
and construction. The Sandwich Plate System comprises two metal plates bonded to a continous elastomer core, which form a much stiffer and stronger system than a single stiffend metal plate. The two elements act compositely which give the material its unique characteristics.

Dual-fuel-electric LNG carriers
– efficient and environmentally friendly. A new generation of LNG carriers is reaching levels that can hardly be matched by a single steam turbine. Dual-fuel-electric machinery is the most suitable choice when powering LNG-carriers.
