MARINTEK has participated in the planning and performance of harsh-weather tests of free-fall lifeboats, which were instrumented to measure speed, heading, motions, accelerations, duct deflection and shaft power, among other parameters.
New types of free-fall lifeboats are continually being developed. Model tests, FEM and CFD analyses all play important roles in this process, as does full-scale testing. The combination of model tests, full-scale tests and simulations is a unique package that MARINTEK can offer.
Model production and model testing are essential parts of our advanced technology development activities at Tyholt. MARINTEK has produced more than 3070 models of ships and platforms, which are subsequently tested in our hydrodynamic laboratories.
The loads on lifeboats and the accelerations felt by their occupants during water entry are influenced by a large number of parameters, such as drop height, the presence of wind and waves, the location of impact point relative to the wave crest. This makes experimental testing of lifeboat design and performance a complex and expensive process. In addition, some conditions cannot even be reproduced experimentally.
Maritime operations in Arctic waters are challenging. The weather can rapidly change from calm to extremely rough conditions. Weather information and forecasts are frequently unavailable, as are reliable data on ice conditions. The lack of adequate infrastructure including communication and qualified navigational data is crucial. We must start preparing for forthcoming Arctic developments immediately in order to close the largest gaps and avoid accidents. Safe navigation, qualified data with ice maps and forecasts, early warning of changes, and monitoring of conditions of ships and structures all need new solutions and a far better communication infrastructure than is currently available.
MARINTEK is well-known for its role in making ships faster, safer, more efficient and more environmentally friendly. This is an important activity, as shipping has rightly been called the life-blood of international trade: between 80% and 90% of international trade is carried by ships. Low cost, high capacity and highly efficient maritime transport services are at the heart of international trade.
