Tanker forward freight agreements: the future for freight futures?

Since paper freight-hedging tools were introduced to counter volatile tanker freight rates, the hesitant uptake of tanker Forward Freight Agreements (FFAs) has been attributed to traditional risk seeking propensities amongst tanker owners, naturally reluctant to hedge against risk. To test how far the well-documented generic determinants and incentives for corporate hedging could explain this hesitation in the tanker market, the attitudes of tanker owners and charterers towards freight hedging, risk and perceptions of FFAs, were surveyed. Although FFAs were widely viewed as an important development, some respondents were unaware of their function and a majority had not used them. The link between freight hedging activity and participants' risk aversion was not clear-cut, but with market liquidity critical to raising FFA usage improved technical education is essential to widespread acceptance

Impacts of Kra Canal and its toll structures on tanker traffic

This article discusses the proposed Kra Canal and its impacts on the tanker market from an economic perspective. We forecast tanker size distributions and further analyze the impacts of toll structures on tanker traffic. The forecast for tanker size distributions is based on distance savings for tankers as potential users of the Kra Canal. The database covers 105 busiest oil transport routes through the Strait of Malacca for the three-year period 2013–2015. Forecasts for individual routes are achieved using an autoregressive model. Two toll polices, namely the willingness-to-pay policy and the differential-pricing policy, are analyzed in order to maximize the annual toll income of the Kra Canal. The findings for the proposed Kra Canal will attract large vessels from the Strait of Malacca. An interesting finding is that the Kra Canal becomes more profitable during an unfavorable tanker market situation when the time-charter rate is low and fuel price is high. The article concludes with a policy that satisfies the goals of canal operator and government.     

The argument for twin screw tankers

According to the CTX tanker casualty database, machinery failures are an important cause of tanker oil spillage. This paper argues that the current large (over 10,000 deadweight) tanker fleet is experiencing at least two full losses of power or steering per day, and probably more than ten. If this fleet were twin screw, properly implemented, this number would be cut by a factor of one thousand. At the same time, tanker low speed maneuverability would be improved dramatically. All this could be done for a net cost of less than that of the double hull.     

On the nature and sorces of controversy in the economic analysis of the liner shipping industry†

The simulations performed show that demand for quality tankers has to increase by 30% for a two-tier tanker market to emerge. The two-tier freight structure will only last for 3–5 years due to contracting induced by higher freight rates. This means that OPA does not by itself result in higher freight rates for tankers that comply with the requirements. If Western Europe also closes their trades to substandard tankers, a two-tier market emerges and quality tankers obtain a premium. The paper presents a simulation model for international tanker markets. The non-linear complementary equilibrium model solves for a sequence of static equilibria in segmented tanker freight markets, shipbuilding and scrapping markets. Freight markets are segmented according to quality requirements for tankers. The model specifies three tanker classes and one—quality tankers—can operate both market segments.
