“…98 If the ship is travelling at or faster than 18 knots (33 km/h), it stays unassailable by pirates. 99 Interestingly, vessels must maintain speeds of at least 18 knots in the Somalian HRA. 100 Studies utilizing real-time vessel tracking have confirmed that lower speeds equal higher piracy risk and, further, that seasons of relatively low piracy risk are distinguished by shipping practices that shift to lower speeds and shorter routes.…”

Maritime commerce in world commerce. Each year, vessels carry more cargo at higher costs and faster speeds. Insurance is an integral part of shipping, as it protects cargoes and crews against the perils of the sea. This article focuses on the peril of piracy, a criminal practice that has evolved significantly throughout history. Pirates today, as pirates of the past, prey upon the unprotected. Yet, modern piracy, unlike historical piracy, is essentially non-violent. The modern pirate profits from ransom, not theft. Today, piracy is a monetary risk with computable consequences: an insurable threat. Anti-piracy methods, including insurance, impose steep costs to world trade. In the past decade, pirate activity has declined while piracy insurance has grown more expensive. This phenomenon is problematic, but an industry-wide solution is a challenging construct. To handle the costly risks of piracy is to balance the distinct and competing interests of ship-owners, insurers, operators, and governments. As this Article argues, insurance can more efficiently mitigate piracy’s puzzling risk. After discussing maritime piracy and maritime insurance, this Article outlines the legal and regulatory schema for a system to mandate the speeds of vessels that transit pirate-prone waters. The proposed regulation is mechanically sound, logistically feasible, cost-effective, and enforceable. To diminish the costly risk of piracy, this Article proposes revising a treaty to afford the International Maritime Organization (IMO) jurisdiction to regulate vessel speeds on the high seas.

“…There are also studies examining and modeling the theoretical relationship between fuel consumption and speeds of the vessels (e.g. Ronen, 1982;Evens and Marlow, 1990;von Westarp, 2020). These studies aimed to develop coefficient models using some important variables.…”

Bu çalışmada, deniz taşımacılığında ana piyasa türleri olan konteyner, kuru yük ve ham petrol filolarının ortalama hızlarını navlun oranı, yakıt fiyatı, filo büyüklüğü ve faiz oranı gibi dış faktörleri kullanarak tahmin ve analiz edilmiştir. Teorik çerçeveye uygun olarak, navlun ve faiz oranları ortalama hızları olumlu yönde etkilerken, yakıt fiyatı ve filo büyüklüğü olumsuz yönde etkilemektedir. Navlun oranı en çok konteyner filosunun ortalama hızını etkilerken, yakıt fiyatı, filo büyüklüğü ve faiz oranı en çok ham petrol filosunun ortalama hızını etkilemektedir; kuru yük filosunun ortalama hızı yakıt fiyatından ve filo büyüklüğünden en az etkilenmektedir; ve konteyner filosunun ortalama hızı faiz oranından en az etkilenmektedir. Genel olarak, faktörler arasındaki katsayı büyüklükleri göz önüne alındığında, üç pazarın ortalama hızlarında en etkili faktör filo büyüklükleridir. Böylece navlun ve yakıt fiyatı çerçevesinde sıkışmış olan ampirik literatüre yeni boyutlar eklenmiştir.

“…Westarp found that the parameters of many existing fuel consumption models were not applicable with a change in conditions in the research process, especially a change in speed [21]. Therefore, a new model was proposed to represent the functional correlation between fuel consumption and speed, and the model was verified by actual collected data.…”

To explore the relationship between fuel consumption and speed for a vehicle on a superhighway with a design speed exceeding 120 km/h, the fuel consumption data provided by the Test of Easy Car platform are used to fit the fuel consumption of different models. The fitting results show that the fitting degree of fuel consumption by a cubic curve is the highest, and the correlation coefficient is above 0.95. A fuel consumption cubic curve model of different vehicle types is established by using the fitting parameters to predict the fuel consumption when a vehicle is running at a speed of 130 km/h–180 km/h. The prediction results show that the average fuel consumption of compact vehicles is the lowest when a vehicle is running on a superhighway at speeds of 130 km/h–180 km/h, with values of 8.95 L/100 km–16.26 L/100 km; the average fuel consumption of sport utility vehicles (SUVs) is the highest, with values of 12.65 L/100 km–22.70 L/100 km. The prediction results can be used to estimate the cost of using a superhighway and provide a basis for estimating the feasibility of superhighways.
