Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the world's largest cruise company, is advancing greater fuel efficiency for propulsion through hull designs and new hardware and technology, along with underwater drone inspection and cleaning trials.This work is done through complementary strategies focused on maximizing hydrodynamic performance and enhancing ongoing hull maintenance, which reduces a ship’s underwater drag. Here's a synopsis of the CCL strategy:Hull Designs: When selecting the optimal hull design…

NLNG Ship Management Limited (NSML) signed a contract with Kongsberg Maritime to deliver Shell’s patented JAWS (Just Add Water System) draft and trim optimization software across the entire NSML fleet of 11 liquefied natural gas (LNG) carriers. JAWS will be distributed using Kongsberg Maritime’s K-IMS digital solution – a portfolio of specialized applications to support complex operations – making K-IMS and JAWS a core element of NSML’s digitalization and cyber security strategies.The JAWS software uses historic…

One of the most effective and easiest fuel reduction operations is reducing the engine power by reducing the speed of a vessel. Out of the total operational costs of a vessel, fuel costs account for, by far, the highest proportion. When fuel prices soared, the technical experts of one of the world’s biggest shipping companies set about to solve the problem, and slowing down was the solution they devised. By 2009 significant fuel savings resulted from sailing its ships at 12 knots instead of 24, and ”Slow Steaming” officially became the standard operating procedure in their fleet.

INTERSCHALT maritime systems AG presents its new fuel saving TROP trim optimization software. The maritime-shipping industry has also been forced to contend with the key issues of energy efficiency and sustainability. Optimizing the trim of a ship is a good way to achieve lasting reductions in fuel consumption. In fact, trim optimization has been an object of investigation since the 1990s. Back then, forward-thinking German shipowners were using models in towing tests designed to determine the trim that produced the lowest resistance as a ship moved through water.
