REVIEW OF ADVANCED MARINE VEHICLES CONCEPTS Apostolos Papanikolaou, National Technical University of Athens, Ship Design Laboratory, Greece (NTUA-SDL) SUMMARY The objective of this paper is to present a review of developments of Advanced Marine Vehicles concepts, with emphasis on the basic techno-economic efficiency of fast passenger and high-value cargo ship designs. The presented work is based on the analysis of data of NTUA-SDL’s Fast Marine Vehicles (FMV) techno-economic database. The collected techno-economic data have been systematically analysed, to assess the transport efficiency of various fast ship concepts and to conclude on the feasibility and viability of candidate designs for specific operational scenarios. 1. INTRODUCTION During the past two decades the maritime community has witnessed a rapid technological evolution of Fast, Advanced Marine Vehicles (AMV) for various applications. In the commercial sector, considerable effort has been devoted worldwide to the development of new types of fast passenger and (to a lesser degree) highvalue cargo ships, in an attempt to increase the share of waterborne transportation against other competing transportation modes in shortsea operations. Many operators have until now been reluctant to consider the introduction of advanced marine vehicles because of the difficulty in assessing their characteristics, the lack of proven operational records and last but not least the dramatic increase of fuel cost, particularly in the last years. As each AMV concept has its own optimal domain of application, wrong selection among the proposed concepts may become disastrous both for the image of the concept and for the viability of rather small operators. An overview of developments of the various AMV concepts on the basis of the prime vehicle’s weight counterbalance force is shown in the Appendix (Papanikolaou, 2002, updated). There it is noted that developments chronologically started from concepts in the upper left corner area (displacement ships, Archimedean hydrostatic weight balance force) and moved towards the right side and downwards with the introduction of more complex technologies. A comprehensive description of technological developments of AMV’s has been recently issued by an international group of authorities (Lamb, 2004). This paper focuses on a review of the basic characteristics of fast passenger ferry and high-value cargo ship designs, considering significant developments within and outside Europe. The technical and economic characteristics of AMVs, presented in the paper, derive from a recently developed techno-economic Fast Marine Vehicles (FMV) database by NTUA-SDL in the framework of an EU funded project (EFFISES, 2001-2005). The collected techno-economic data have been systematically analysed, in order to assess the transport efficiency of various fast ship concepts with the aim to assist the designer, shipowner or other interested parties in the evaluation of candidate technical solutions for specific operational scenarios. Empirical formulae relating major design characteristics of various high-speed concepts have been derived based on regression analysis of the collected data (Papanikolaou et al, 2001). Emphasis has been placed in the assessment of two hybrid Air Lubricated Hull (ALH) EFFISES concepts, currently validated by open sea experiments of two scaled 9m prototypes (Papanikolaou et al., 2004). The main characteristics of the investigated EFFISES concepts are shown in Table 1. 2. PRESENTATION OF DATA SAMPLE The NTUA-SDL FMV database considers technoeconomic data of a significant portion of high-speed vehicles operating worldwide (sample size in June 2005: 657 registered vessels, Froude number over 0.70). The main source of data is both public domain information and confidential data of NTUA-SDL deriving from past and ongoing research in this area. Compared to commercially available relevant databases, it is characterized by the availability of a satisfactory set of data regarding ship weights (displacement, payload, deadweight and lightship weight) and building costs. Figures 1 to 5 illustrate the main database menu with some main features of the database and the repartition of the collected data with respect to ship type, length, speed, etc. Figure 1 FMV Database NTUA-SDL June 2005 Cargo Vessels 0,0% REPARTITION " High Speed Passenger Vessels " Passenger / Car Vessels 35,6% Total : 657 ships Passenger Vessels 64,4% Passenger Vessels Passenger / Car Vessels Cargo Vessels Figure 2 SWATH 1,2% ACVAS 0,2% FMV Database NTUA-SDL June 2005 Semi SWATH 1,4% Planing Monohull 22,1% REPARTITION "All Vessels" Wave Piercer Catamaran 10,6% entional Hydrofoil 8,1% Total : 653 ships Catamaran 34.1% SES 6,6% Wave Piercer Catamaran Conventional Hydrofoil Semi SWATH Catamaran ACV Unknown SES ACVAS Planing Monohull SWATH Figure 3 FMV Database NTUA-SDL June 2005 REPARTITION " Distribution of Analysed Ships acc. to Loa" Above 90m 16,8% Total : 648 ships Below 50m 62,2% 50m - 90m 21,0% Below 50m TRANSPORT EFFICIENCY ANALYSIS The Transport Efficiency of a marine vehicle may be defined in various ways and a series of researchers have addressed this in the past. In the following, a review of past work is attempted and complemented by recent work of the author. The Transport Efficiency may be defined as a function of the vessel’s deadweight Wd (t), service speed Vs (kn) and total installed power P (kW) and is presented for a sample of AMVs in Figure 6. E1 = Unknown 0,5% ACV 2,0% 3. 50m - 90m Above 90m Figure 4 Wd ⋅ VS P (1) The Transport Efficiency may be also defined with respect to the vessel’s payload Wp (t) instead of deadweight, and is presented in Figure 7. W p ⋅ Vs E2 = (2) P Comparing the transport efficiency of marine vehicles with that of alternative modes of transport (land- and airborne), it is very useful to employ the well known v. Karman-Gabrielli transport efficiency diagram. Akagi (1991) has re-plotted the original Karman-Gabrielli diagram, in terms of the reciprocal Transport Efficiency as a function of the total installed power P (PS), displacement W (t) and maximum speed V (km/h): 1 P = E3 W ⋅ V (3) and Akagi–Morishita (2001) added more recent developments of various transport vehicles. Figure 8 presents the reciprocal Transport Efficiency once more updated by sample data of the NTUA-SDL database, whereas Figure 9 is focusing on the performance of the marine vehicles only. The reciprocal Transport Efficiency (specific power), may be based also on payload Wp (t): 1 P (4) = E4 W p ⋅ V 2 and is presented in Figure 10. Above 45 kn 8,3% FMV Database NTUA-SDL June 2005 Below 30 kn 12,9% REPARTITION " Distribution of Analysed Ships acc. to Service Speed " 40 - 45 kn 20,9% Total : 611 ships 30 - 35 kn 32,2% 35 - 40 kn 25,5% Below 30 kn 30 - 35 kn 35 - 40 kn Figure 5 40 - 45 kn Above 45 kn Akagi (1991) plotted the payload ratio (Wp/W) of various transport vehicles against their maximum speed (in km/h). This plot has been updated in Figure 11 by additions of the FMV-NTUA database. Akagi and Morishita (2001) also analyzed the Specific Power 1/E2 as: P P W Wd (5) = ⋅ ⋅ W p ⋅ V W ⋅ V Wd W p and plotted each term separately. The deadweight and payload ratios against V, W and volumetric Froude number F∇ are plotted in Figures 12 – 20, as updated by the FMV-NTUA sample data. Wright’s results, amended by FMV-NTUA data are presented in Figures 27 and 28. TF = K2 ⋅W SHPTI /( K 1 ⋅ VK ) (6) where K2 is a constant (K2= 2240 lb/LT), W is ship’s displacement in LT, SHPTI is the total installed power in HP, K1 is a constant (K1= 1.6878/550 HP/lb-kn) and Vk is the design speed in kn. Figure 21 presents Kenell’s transport factor vs. speed updated with the relevant FMV-NTUA database data. Following Kennell’s approach, the displacement and transport factor are decomposed as follows: W=Wship+Wcargo+Wfuel TF=TFship+TFcargo+TFfuel (7) (8) Where Wship, Wcargo, Wfuel are the lightship, cargo and fuel oil weight respectively (in LT), and TFship, TFcargo, TFfuel are the transport factors, calculated for each weight group. Wship and Wfuel are obtained from the following equations: Wship =W- Wcargo- Wfuel W fuel = SFC avg ⋅ K SHP ⋅ SHPTI (9) R K S ⋅V K (10) where SFCavg is the average effective fuel consumption rate, KSHP is the endurance power to design power ratio, R the range (in n.m.), KS the endurance speed to design speed ratio. Figures 22 to 25 show the fuel transport factor vs. range and the trends of transport factors and various fractions thereof, as plotted by Kennell and updated by the FMVNTUA database ships. Hearn et al. (2001) used Kennell’s transport factor to compare current technology catamarans, semi-SWATHs and wave-piercers against a defined Technology Barrier. Figure 26 shows an update of Hearn’s diagram by data of the FMV-NTUA database ships. Finally Wright (1990) examined the relation between BHP/Passenger and speed/length ratios for passenger crafts of about 200 passengers and calculated the Transport Efficiency of various high speed crafts. Wright’s Transport Efficiency is defined as: 4. CONCLUSIONS The present state of the art of technological developments of Advanced Marine Vehicles allows the consideration of a wide variety of fast marine vehicle concepts, for various applications. The transport efficiency of the various investigated concepts clearly depends on design speed, route length, payload/displacement ratio and absolute vessel’s size. When considering commercial applications the selection of the optimal concept presumes the specification of an accurately defined operational scenario, following a market research with respect to the transport volume, market shares and the performance of alternative transport vehicles (speed and cost), including conventional vessels and, if applicable, airborne and land vehicles. For the specified operational scenario alternative candidate AMV concepts may be assessed with respect to a variety of cost merit functions and design constraints. This assessment should include, along with the calm water performance of candidate concepts, their performance at service speed under the selected operational seaway conditions, characterizing the area of operation. The Transport Efficiency analysis of the envisaged Air Lubricated Hull EFFISES prototype designs appears quite competitive compared to other types and modes of fast transport. If the preliminary design results of the EFFISES prototypes are confirmed by the planned open sea tests, it is believed that the envisaged ALH hybrid designs will represent an attractive alternative for the fast transportation of passengers and high-value cargo.
