AIS data and the price of oil : a study of predictive feasability
Flaate, Aslak Wøllo; Nikitina, Maria (Master thesis, 2018)Compared to the oil market, physical movement of oil-carrying vessels is very precise and reflects the real production rates more timely than official reports. In this paper, we examine whether detailed information on ... -
A logit model for the lay-up decision in the north sea Offshore rig market
Skeide, Markus; Horn, Helge (Master thesis, 2017)The thesis examines the lay-up decision in the North Sea offshore rig market from 2010 through march 2017. Using empirical analysis, we have specified a logistic regression model to investigate how rig characteristics, ... -
Are AIS-based trade volume estimates reliable? The case of crude oil exports
Ådland, Roar Os; Jia, Haiying; Strandenes, Siri Pettersen (Peer reviewed; Journal article, 2017)Most global trade statistics in the public domain refer to official customs data, which are not generally available on a micro (individual cargo) level. With the increasing availability and completeness of ship positioning ... -
Asset bubbles in shipping? : an analysis of recent history in the drybulk market
Ådland, Roar Os; Jia, Haiying; Strandenes, Siri Pettersen (Discussion paper, Working paper, 2006-03)The purpose of this paper is to investigate the hypothesis that the supercycle in the drybulk freight market between 2003 and 2005 caused asset values in the second -hand market to deviate from underlying fundamentals. ... -
Can you hedge ship price risk using freight derivatives? : a study of the dry bulk market
Ameln, Haakon; Børnes, Eirik August (Master thesis, 2018)This thesis investigates the possibility of reducing ship price risk in the dry bulk sector using freight derivatives. We establish a theoretical linkage between ship prices and FFA prices and empirically test this ... -
Determinants in the Lay-Up Decision: An empirical study on offshore support vessels
Sværen, Oda Aspebakken (Master thesis, 2017)When a downturn hits the cyclical offshore service industry, shipowners attempt to improve their cash flow and the market balance by laying up vessels. The purpose of this master thesis is to evaluate how micro- and ... -
A discrete-time stochastic partial equilibrium model of the spot freight market
Ådland, Roar Os; Strandenes, Siri Pettersen (Discussion paper, Working paper, 2004-03)This paper presents a stochastic extension of the classical partial equilibrium models of the spot freight market. The supply in the model is based on microeconomic analysis of the supply characteristics of a given fleet ... -
A discrete-time stochastic partial equilibrium model of the spot freight market
Ådland, Roar Os; Strandenes, Siri Pettersen (Report, Research report, 2004-04)This paper presents a stochastic extension of the classical partial equilibrium models of the spot freight market. The supply in the model is based on microeconomic analysis of the supply characteristics of a given fleet ... -
Does fuel efficiency pay? Empirical evidence from the drybulk timecharter market revisited
Ådland, Roar Os; Alger, Harrison Marshall; Banyte, Justina; Jia, Haiying (Journal article; Peer reviewed, 2017)The time charter market for ships represents a classical example of the principal-agent problem, where shipowners can opt to invest in energy efficient ships, yet any savings in fuel expenditures accrue to the charterers. ... -
FFA hedging in the supramax segment : how alterations of the Baltic supramax index have affected hedging efficiency
Aarheim, Georg Martin Steen; Holseter, Ole Morten (Master thesis, 2018)This thesis studies how altering the composition of the Baltic Supramax Index (BSI) affects the hedging efficiency of forward freight agreements (FFA) traded with the index as underlying. We evaluate the hedging efficiency ... -
Multivariate modeling and analysis of regional ocean freight rates
Ådland, Roar Os; Benth, Fred Espen; Koekebakker, Steen (Peer reviewed; Journal article, 2017)In this paper, we propose a new multivariate model for the dynamics of regional ocean freight rates. We show that a cointegrated system of regional spot freight rates can be decomposed into a common non-stationary market ... -
A non-parametric model of the timecharter-equivalent spot freight rate in the very large crude oil carrier market
Ådland, Roar Os (Working paper, Working paper, 2000-01)The empirical research in this paper uses non-parametric techniques to avoid arbitrary parametric restrictions on the underlying freight rate process. The relevant hypotheses include: mean reverting freight rates in the ... -
Obtaining contracts in the North Sea OSV market : a vessel based logit model
Tvedte, Morten Vik; Sterud, Alexander (Master thesis, 2016)This thesis studies the determinants for obtaining contracts in the North Sea offshore supply market from 2007 to 2016. We specify a logistic regression model to investigate the effect of vessel specifications on the ... -
Offshore service vessel contribution to the air pollution in a port city : estimation of aggregate emissions for the Port of Bergen
Hawryłko, Izabela (Master thesis, 2017)The main subject of this thesis are emissions released by an offshore fleet visiting the Port of Bergen. In its first part, a problem of shipping-related pollution is introduced. It includes a description of main emission ... -
Price Premiums in the Shipbuilding Market : A study of determinants for bulker, tanker and container segments in the 1990-2014 period
Norland, Kristian; Sætrevik, Even (Master thesis, 2016-09-01)In this thesis we investigate whether a number of variables specific to a vessel, the contracting parties, or market conditions affect the price charged for the ship. Literature in maritime economics seems to suggest ... -
Revenue determinants in the offshore support vessel market : a study of North Sea fixtures
Wiig, Asmund; Tvedte, Marius Vik (Master thesis, 2017)The purpose of this thesis is to investigate the vessel-specific determinants of commercial success, measured by vessel revenue, in the North Sea Offshore Support Vessels (OSV) market. By studying the characteristics and ... -
Simulating physical basis risks in the Capesize freight market
Ådland, Roar Os; Jia, Haiying (Peer reviewed; Journal article, 2017)The purpose of this paper is to evaluate the characteristics of the time-varying differential between the Baltic global trip-charter average and simulated earnings from a fleet of Capesize vessels. We interpret the standard ... -
Technical trading rule performance in the second-hand asset markets in bulk shipping
Ådland, Roar Os (Working paper, Working paper, 2000-01)This paper investigates the performance of technical trading rules applied to asset play in the international bulk shipping industry. The rules are tested on monthly returns in the Products Carrier segment for the period ... -
The economic impact of fuel consumption uncertainty for tankers
Baik, Donggon (Master thesis, 2016-09-02)In this thesis, we evaluate how uncertainties in ship operation, particularly fuel consumption, impact speed optimization and profit maximization. By courtesy of SKS Tankers AS, three years of noon reports and the ship ... -
The impact of regional environmental regulations on empirical vessel speeds
Ådland, Roar Os; Fonnes, Gro; Jia, Haiying; Daae Lampe, Ove; Strandenes, Siri Pettersen (Journal article; Peer reviewed, 2017)Economic theory suggests that the use of more expensive low-sulphur fuel within an Emission Control Area (ECA) should result in lower vessel speeds. The objective of this paper is to investigate empirically, for the first ...
