Norway’s Kongsberg Maritime onTuesday showcased a brand-new line of overseas ship layouts in its UT Design profile.
The brand-new support trainer (AHT) as well as system supply vessels (PSV) have the choice to consist of different power resources as well as gas, such as methanol, ammonia, as well as hybrid-battery power.
The AHT as well as PSV layouts have actually obtained Approval in Principle from course culture DNV to run with ammonia-fuelled engines as well as they can include an overseas billing qualified plug-in crossbreed choice, to allow emission-free battery-powered procedure.
Einar Vegsund, Director, Ship Design Solutions, Kongsberg Maritime, claimed: “Kongsberg’s iconic UT vessels have been the benchmark design for the offshore industry for the past 50 years. These latest designs combine decades of experience and the latest innovative Kongsberg technologies to offer customers next-generation ships that are equipped for the future.
“Our ship designs continue to evolve, and changes to regulations and uncertainty around preferred fuels have driven the demand to create ships that are ready for the future and give owners the confidence to invest, knowing their ships can adapt to meet future requirements.”

Martijn de Jongh, Chief Designer of Specialised Vessels, Kongsberg Maritime, included: “A great deal of work has gone into ensuring this new range of ships gives owners a reduction in environmental footprint. We have drawn on the results of numerous R&D programs including hydrodynamic optimization, assessing offshore battery charging, and in cooperation with Amon Maritime, obtained the Approval in Principle for the use of ammonia as a fuel.
“One of the great innovations the anchor handler design offers is significantly reduced energy consumption during anchor operations. This is achieved through the use of Kongsberg’s cross-tensioning system where the load testing of anchors will use the power of the winches rather than the traditional approach of one or more vessels using bollard pull and engine power. This approach will lead to significant operational cost savings, enabling this crucial offshore task to be handled by a single ship”.
The support trainer array, called UT 7800, will ultimately consist of 4 dimensions, varying from little to extra-large, with bollard pulls of 180 heaps for the little variation, boosting to over 400 heaps for the biggest variation of the ship.
Martijn de Jongh includes: “The UT 7800 has been designed for initial operation in the traditional oil and gas anchor handling market, but it is very adaptable for future offshore energy developments, such as floating wind. While we are also designing ships specifically for the offshore wind market, the UT 7800 range has the benefit of being able to operate at first in oil and gas, then, if desired, it can be adapted to serve operations in new, evolving markets.”
Kongsberg claimed it would certainly use an option of winch arrangements as well as abilities, along with versatile chain as well as rope handling as well as storage space ability. ROVs as well as cranes can additionally be incorporated right into the layouts.
For the biggest vessels, the deck tools as well as setup have actually been maximized for the bigger measurements as well as weights of the rope, chain, as well as tools than is common within oil as well as gas, making it possible for procedures outside these conventional markets.
