COMBINED ENERGY AUDITS AND TRAINING LEAD TO HIGH FUEL SAVING

Today fuel efficiency is a key word practically in all stages of shipbuilding and shipping. New projects are developed with utmost attention on fuel efficiency related to hull geometry, hull openings, appendages, hull roughness, system configuration and performance. RANSE-theory based CFD is applied on developing the hull shape with all its details before starting model testing. Model tests are carried out to reach the absolute state of the art design, not only to fulfill specification.

Systems are configured and simulated to operate at maximum efficiency in typical operational conditions, not just dimensioned for certain maximum conditions.

Energy audits are carried out during the design and building period of a newbuilding and during operation. These audits combined with efficient training will secure the most fuel-efficient use of the vessel, its systems and maintenance.

Deltamarin has built eight training programs, held at its own offices, comprising 10-day courses to consider the principal sources of fuel consumption onboard cruise ships such as propulsion, air conditioning and energy production.

Royal Caribbean Cruise Line and Celebrity Cruises were the first to take up these training programs at the end of 2004, and about 120 persons will be trained by the end of 2006. This program has been further developed into three/four-day courses.

Several cruise and ferry operators are taking up these training programs. The new courses can be offered at the client’s premises either onboard, ashore or combined, or at Deltamarin premises.

Energy audits of complete fleets are being carried out and in most cases they are combined with efficient officer and superintendent training. Typically 10 to 15 fuel saving actions are found and recommended, with low investment costs leading normally from 2 to 6 months payback time. The typical fuel saving potential is varying between 5 to 12 %, but even higher figures have been found in certain specific cases.
