HSMV cluster [7]. Since then, overviews on
knowledge needs related to design and performance of
HSMV have been presented in recent conferences [8] -
[10] and published by the International Towing Tank
Conference [11] – [12]. International regulations by the
International Maritime Organisation (IMO) [13], and
the International Work Boat Code [14], are important
guidelines for new designs. Papers written by
Norwegian and international researchers [15] – [20]
show the need for studies of HSMVs related to
challenges in design, construction and operation. There
is a distinct lack of works on zero and reduced emission
propulsion systems for HSMV.
In Norway many of the passenger HMSVs are on
contracts with regional transport authorities. These
contracts have a limited duration (5 to 10 years). The
parameters used in evaluation of the offers from
possible suppliers have changed over the years. For the
most recent contracts price, emission profile and
regularity are parameters used for ranking of the
offers. This implies that it is risky to optimize a new
vessel design for a specific route. In general, emission
requirements have resulted in increased vessel weight
for the power solution.
The first part of the paper gives a brief description
of the Norwegian history of design, building and
operation of HSMV, where the joint governmental and
industry funded High Speed Marine Vehicles R&D
programme [7] played an important part for the
growth of the Norwegian HSMV industry. In addition
to passenger vessels, the industry has developed fast
patrol boats, ambulance and Search and Rescue
vessels. Some operability aspects and challenges for the
existing fleet of HSMV will be presented.
The second part focusses on the recent work to
develop a new generation of HSMV for passenger
transport in Norwegian Coastal waters. Governmental
requirements specifying significant reduction of GHG
emissions from shipping have a significant impact on
the design and operation of future HSMV. New
designs should primarily be zero- or low-emission
vessels and easily adapted to specific operational
patterns (confined/open waters, transit distance,
passenger capacity, terminal layout). Ongoing
activities related to reduction of vessel resistance
(hydrodynamic and aerodynamic), improving
propulsion systems and use of different power sources
(batteries, new green fuels), will be presented. Specific
problems such as wake wash, hydroacoustic signature
and harsh weather operability will be highlighted.
Numerical tools and model tests used in development
and assessment of new HSMV designs will briefly be
presented and discussed.
The final part of the paper contains a summary of
the governmental sponsored “HSMV for the future”
projects [21] - [22]. Norwegian designers were late 2021
invited to sign an R&D contract for design of a zero
emission HSMV with 30% lower energy consumption
compared to the 2021 reference vessels. Four concepts
passed the first evaluation and were invited to
continue the design process to a level where the design
specifications were developed, high-level drawings
approved and building costs estimated. Focus will be
on the work done by the Norwegian design company
ESNA in their development of one of the two final
designs
2 HISTORY OF HSMV IN NORWAY
2.1 Early days – 1960 – 1985
Norway has the second longest coastline in the world,
with approximately 20.000 km. It has long and wide
fiords and a scattered population in remote areas on
islands and small communities on the mainland. Lack
of (or unsafe) roads in these areas requires seaborne
transportation.
The first HMSV started operation in commercial
passenger traffic in the late 1960-ties. It was a hydrofoil
vessel built in aluminum by Cantieri Navali Rodriquez
in Italy and named HF Vingtor. It operated on the route
Stavanger – Bergen until 1974, see figure 1. Calm
weather operational speed was 30+ knots. Two
additional vessels were delivered in 1961 for this route,
HF Sleipner and HF Teisten. Later, Norwegian ship
designers and yards became more involved in
production of different types of HSMVs. In total
approximately 40 HSMV were in operation in
Norwegian waters during this period.
2.2 The golden age of Norwegian High Speed Marine
Vehicle industry – 1985 - 2010
In the late 1980-ties the Norwegian share of
commercially operated high-speed marine vehicles
was close to 15 % of the total world fleet of such vessels
(approximately 800). At that time, Norwegian design
and construction of larger High Speed Catamarans
(HSC) and Surface Effect Ships (SES) constituted
approximately 40% of the world market. Operations in
harsh Norwegian coastal waters imposed extreme
demands on the quality and performance of the craft as
well as its crew.
As a response to new operational and technological
challenges, a joint R&D program supported by the
industry and governmental R&D authorities were
initiated by MARINTEK (now SINTEF Ocean) and
NTH (now Norwegian University of Science and
Technology – NTNU) in 1988. Royal Norwegian
Council for Scientific and Industrial Research (NTNF)
launched in 1988 a four-year R&D programme “High
Speed Marine Vehicles“ [7], with a total budget of 108
MNOK. Table 1 lists the industrial concepts and
products related to the programme. The main objective
for the program was to:
− Develop knowledge and technology to improve the
competitiveness of the Norwegian HSMV industry
and operators.
To obtain the objective it was found necessary to:
− Establish the future technology base
− Focus on safety, economics and environmental
effects
The R&D areas were divided into:
− Basic technology
− Industrial concepts
During the project period, the Norwegian built
HSMV in operation went from 131 (in 22 countries) to
158 (in 28 countries). No major joint industry R&D
programme on HSMV has been initiated since the end
of the “High Speed Marine Vehicle” program in 1992.
The different industry partners have run in-house R&D
