Sustainable Methods for Optimal design and Operation of ships with air-lubricaTed Hulls
Air lubrication of Ship hull a large potential gain in hull effciency of up to 20%. SMOOTH seeks to fill missing technology gaps and enable air lubrication of hulls within normal European shipbuilding and operation practice for both inland and coastal ships.
While the basic concept of air lubrication is old, limited serious research has been performed. It was the PELS project, a Dutch national project that made a positive change. This project demonstrated that a positive overall energy gain can be achieved in all operational conditions with air lubrication. The required technology itself is new and requires further exploration. Based on the findings from the PELS project, the SMOOTH consortium estimates that ship hull efficiency improvements of up to 20% will be feasible. Such a step forward would be beneficial to the environment since the considerable reduction of fuel consumption will have its effect on the CO2, NOx and soot discharges. A reduction of fuel consumption will, of course, also be welcomed by the European shipping business since it will result in a reduction of costs.
European policies are addressed in a number of ways: the noticeable reduction of the operational costs by reducing the ship’s resistance, the enhancement of the quality and operational safety of the transport process, and the safer transport of crude oil and other dangerous and potentially polluting goods. The SMOOTH project facilitates the inter-European knowledge exchange, by providing a platform of co-operation for SMEs, companies and research institutes from six different European states, including and candidate country Turkey.
As air lubrication has been successfully tested for model ships, new products (in terms of suitable ultra repelant painting systems, ambient and functional air distribution and control systems) need to be developed further to apply this technique to vessels. The resulting verifiable and measurable objectives for the Smooth project are:
- to provide validated (finally tested on model scale) computational tools for a real ship design
- to validate scale effects of air lubrication
- to evaluate the economy of air lubrication in practice and demonstrate the concept at full size on an inland vessel.
- to prepare the safe introduction of air-lubricated ships in practice.
The strategic objective of SMOOTH is to apply air lubrication to ships and to provide the necessay new products in terms of control and paint systems to introduce air-lubricated ships. These ships may utilise micro-bubble (MB), air-film or air-cavity systems (ACS), for inland and coastal navigating ships with relatively shallow drafts.
Description of work
SMOOTH has defined a number of work packages.
WP1: Project management
WP2: Experiments on air films
WP3: Scale effects and sea trials
WP4: Model tests on air films
WP5: Model tests on micro-bubbles and air-cavity ships
WP6: Economic plus risk evaluation
WP7: Evaluation and dissemination
The techniques surveyed in SMOOTH for practical application and implementation in the coming generation of European ships will include in addition to improved drag and power-reduction , other innovations such as better stopping and manoeuverability.
Novel painting systems for ships and new air-control systems aboard ships will strengthen the position of the European shipbuilding industry represented within the Smooth consortium.
