Elements of Ship Dynamics and Marine Hydromechanics - Lecture Notes
(Aalto University, 2022) Hirdaris, Spyros; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
The concept of ship dynamics has a very wide meaning, embracing the fundamentals of both deterministic and performance-based methods. A Naval Architect is expected to have sound appreciation of theoretical concepts of relevance to the prediction and validation of ship seakeeping, dynamic stability, added resistance and manoeuvring in waves. This set of course notes attempts an introduction to the subject along the lines of a synonymous Marine Technology course delivered at Aalto University. The information is presented in ten chapters corresponding to ten lectures and should be considered auxiliary to class tutorials and ship design focused coursework. Special emphasis is attributed on ocean waves, seakeeping, maneuvering and associated principles of marine hydromechanics. The content assumes good knowedge of principles of Naval Architecture, Marine Engineering and is appropriate for last year undergraduate, MSc and DSc students as well as early career professionals. Additional useful information is included in the textbooks: [1] Hirdaris, S., Mikkola, T.K. (2021).

Principles of Ship Buoyancy and Stability
(Aalto University, 2021) Ruponen, Pekka; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
Buoyancy and stability are the most important technical parameters of a ship. These must be carefully considered throughout the design process. Furthermore, relevant stability criteria are frequently checked also on board the ship. In this book the theory of ship buoyancy and stability are presented with several practical applications. The relevant regulations of the International Maritime Organization (IMO), for both intact and damage stability, are also briefly reviewed. The focus is on the underlying physics and description of the applied assumptions and simplifications in the regulations. Therefore, the material is believed to be useful also for graduated naval architects in the industry.
Lecture Notes on Basic Naval Architecture
(Aalto University, 2021) Hirdaris, Spyros; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
Shipping is responsible for 90% of world trade. The design, equipment and function of ships are subject to constant evolution that intensified recently because of emerging sustainability and safety requirements, the changing patterns of world trade and technological evolution. It is becoming increasingly evident that the Naval Architects and Marine Engineers of the future will be less tied to conventional ship types, will work in less deterministic ways and will have to adapt to market demands. Yet good understanding of the basics shall remain essential. With the above in mind, this set of lecture notes outlines some of the Principles of Naval Architecture and Marine Engineering for use in concept ship design. The material presented can be used by undergraduate students or early stage postgraduate students of Marine Technology.
Dynamics of a Rigid Ship - with applications
(Aalto University, 2021) Matusiak, Jerzy; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
This textbook is a result of the work started in 1996 when I joined a very interesting, newly formed Specialist Committee working on Ship Stability within the International Towing Tank Conference (ITTC). Thanks to this group of international enthusiastic scholars in the field, it became clear for me that both the research and the rules’ development in the field of ship stability will proceed in the direction of including ship dynamics into account. Moreover, this development will require sophisticated mathematical models of ship dynamics based on the first principles and taking realistically into account the environmental, often very hostile, conditions. These models should be verified and thoroughly validated. I am very grateful to Professor Eero-Matti Salonen for his valuable comments and corrections he has made to the original manuscript. I want to thank my colleagues Messrs Teemu Manderbacka and Otto Puolakka, the assistants in the course on Ship Dynamics, for their valuable remarks concerning the lecture notes that were the bases of this book. I also want to thank Dr. Timo Kukkanen for reviewing the manuscript.
Navigoinnin menetelmät: Johdatus teknologiseen navigointiin
(Aalto University, 2020) Vermeer, Martin; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Ihminen on historian aikana aina navigoinut. Teknologinen navigointi syntyi merenkulussa, koska avomerellä tarvittiin mittauksia oman sijainnin määrittämiseksi. Lentokoneet, ohjukset ja avaruusalukset sekä kuivalla maalla liikkuvat kulkuneuvot ja jopa jalankulkijat kaikki ”navigoivat” nykyteknologioiden avulla. Kehitys on pääosin kahden teknologian ansiota: satelliittipaikannuksen, kuten GPS:n (Global Positioning System), ja inertianavigoinnin. Myös tieto- ja viestintätekniikka on kehittynyt, erityisesti rekursiivinen lineaarinen suodatus eli Kalmanin suodin. Lisäksi pienet ja hinnaltaan huokeat digitaaliset anturit ovat mullistamassa jokapäiväisen navigoinnin. Tässä kirjassa käsiteltäviä aiheita ovat navigoinnin perusteet, stokastiset prosessit, Kalmanin suodin, inertianavigoinnin teknologiat ja menetelmät, GNSS-signaalien rakenne, kantoaallon vaihemittaukset ja kokonaistuntemattomat, tosiaikainen GNSSpaikannus ja navigointi, differentiaalikorjausten viestintäratkaisut ja standardit, GNSStukiasemat ja -verkot, satelliittipohjaiset parannusjärjestelmät, ilmagravimetria sekä anturifuusio ja sattuman anturit.
Methods of navigation: An introduction to technological navigation
(Aalto University, 2020) Vermeer, Martin; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Historically, humankind has always navigated. Technological navigation originated in seafaring, because on the open ocean, measurements are needed in order to determine one’s own location as a part of navigation. Aircraft, rockets and spacecraft as well as vehicles moving on dry land, and even pedestrians, all ”navigate” by means of modern technologies. This development is mainly due to two technologies: satellite positioning, such as GPS (the Global Positioning System) and inertial navigation. Also information and communication technologiy has evolved: especially recursive linear filtering or the Kalman filter. Furthermore, small and inexpensive digital sensors are revolutionising everyday navigation. Subjects explained in this book are the fundamentals of navigation, stochastic processes, the Kalman filter, inertial navigation technology and methods, GNSS signal structure, carrier-phase measurement and ambiguities, real-time GNSS positioning and navigation, communication solutions and standards for differential corrections, GNSS base stations and networks, satellite-based augmentation systems, airborne gravimetry, sensor fusion and sensors of opportunity.
Fysikaalinen geodesia
(Aalto University, 2020) Vermeer, Martin; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Physical geodesy studies the large-scale figure and gravity field of the Earth, which are closely related. Our understanding of the gravity field is based on Newton’s theory of gravitation. We present field theory, with partial differential equations describing the behaviour of the field throughout space. Techniques for solving these equations using boundary conditions on the Earth’s surface are explained. A central concept is the geopotential. The figure of the Earth is approximated by an ellipsoid of revolution, after which the precise figure is described by small deviations from this ellipsoid. Vertical reference systems are discussed in this context. Extending the approach to the Earth’s gravity field yields small difference quantities, such as the disturbing potential and gravity anomalies. Approaches to modelling the gravity field explained are spectral development of the field using spherical harmonics, the Stokes equation, numerical techniques based on the Fast Fourier Transform, the remove-restore technique, and least-squares collocation. Gravity measurement techniques are discussed, as are the multiple links with geophysics, such as terrain effects, isostasy, mean sea level and the sea level equation, and the tides.

Geodesy: The science underneath
(Aalto University, 2019) Vermeer, Martin; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Geodesy is the science of precisely measuring and mapping the Earth’s surface and locations of objects on it, the figure of the Earth and her gravity field, and changes in all these over time. Geodesy is an old science, going back to the days when land was taken into agricultural use and needed to be mapped. It is also a modern science, serving vital infrastructure needs of our developing global technological society. This text aims to describe the foundations of both traditional geodesy, mapping the Earth within the constraints of the human living space, and modern geodesy, exploiting space technology for mapping and monitoring our planet as a whole, in a unified threedimensional fashion. The approach is throughout at conveying an understanding of the concepts, of both the science and mathematics of measuring and mapping the Earth and the technologies used for doing so. The history of the science is not neglected, and the perspective of the presentation is unapologetically Finnish.
Geodesia: Kaiken perusta
(Aalto University, 2019) Vermeer, Martin; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Geodesia on tiede, joka mittaa ja kartoittaa tarkasti Maan pintaa ja sen päällä olevia kohteita, Maan muotoa ja painovoimakenttää, sekä niiden kaikkien ajallisia muutoksia. Geodesia on vanha tiede, joka oli olemassa jo muinoin kun maanviljely alkoi ja peltoja piti kartoittaa. Se on myös moderni tiede, joka palvelee modernin, kehittyvän globaalin teknologisen yhteiskuntamme olennaisia infrastruktuuritarpeita. Tämä kirja esittää sekä perinteisen että modernin geodesian perusteet. Perinteinen geodesia kartoittaa Maata ihmisen elintilan puitteissa ja sen ehdolla, kun moderni geodesia käyttää avaruusteknologiaa koko maaplaneetamme kartoittamiseksi ja seuraamiseksi yhtenäisellä kolmiulotteisella tavalla. Tavoitteena on auttaa Maan mittaamiseen ja kartoittamiseen liittyvien sekä tieteellis-matemaattisten että teknologisten käsitteiden ymmärtämistä. Geodesian historiaa ei unohdeta, ja kirjoitelman näkökulma on avoimesti suomalainen.
Real Estate in Finland (Second Edition)
(Aalto University, 2017) Hiironen, Juhana; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
Finland is well-functioning and stable economy which has transformed itself into a modern welfare society in a matter of decades. During the late 1990's, strong growth transformed Finland into one of the world's most competitive economies. In global reports Finland is appreciated highly for the functioning of its institutional framework as well as health and primary education. Finnish weaknesses include the small market size, weak macroeconomic conditions, and the inflexibility of its labour markets. Since the financial crisis, the competitiveness and the financial stability of the economy has fallen. The growth of the Finnish economy has been weak in recent years. For 2017 and 2018, slightly positive GDP growth is forecasted, mainly based on domestic demand. Despite the current economic situation, Finland is still one of the richest country in the world and enjoys a high level of income and well-being. There has been a huge developent in the Finnish real estate sector during the past decades. New players have emerged, foreign investments have grown, internationalisation and professionalism has increased which have resulted in new practices in property investment processes. Owning a real property in Finland means owning the land and the buildings on it. This is the basic form of direct real property ownership. In practice it is very common for property ownership to be organised through a limited company founded for the sole purpose of owning the property. There are no restrictions on buying or selling real estate. Transactions with housing or real estate company shares are straightforward and simple. As soon as transfer taxes have been settled, the purchaser can be registered as the owner of the shares in the company's registers. Also the Finnish legislation regulating rental agreements is among the most liberal in the world and is based on the idea of full freedom of agreement between two parties. Land use in Finland is regulated by the Land Use and Building Act. The system has three levels of land use plans: a regional land use plan, a local master plan and detailed local plans. Regulations and guidelines complement the legislation. During the past decade planning process has taken more open and interactive approach to planning. The local planning process is aimed at facilitating the involvement of all those concerned in planning: landowners, residents and businesses in the area.
Dynamics of a Rigid Ship
(Aalto University, 2017) Matusiak, Jerzy; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
The approach to ship dynamics presented in the book makes it possible to deal with the seemingly different problems such as ship maneuvering, sea-keeping and dynamic stability using the same unified mathematical model. Motion dynamics of a ship regarded as a rigid body in a general motion with six-degree-of-freedom is considered. The relation of non-linearities of the applied sub-models to the physical phenomena associated with the ship behavior is discussed. Surface wave theory is presented. Non-linearities associated with surface waves are discussed. Realization of the unified mathematical model in a form of simulation tool, called LaiDyn, is discussed and examples of its applications are shown. Mathematical model for assessing internal hull girder loads is presented briefly. An un-symmetry of internal loads, visible as different maximum values of sagging and hogging, is presented and the origins of it are discussed.
