Seatrout: Double Hull Product Tanker The 40,600-dwt double hull tanker Seatrout was delivered from Lindenau GmbH Schiffswerft & Maschinenfabrik in June 2006. Built for the transport of oil and oil products to Ice Class E3 starndard, the ship is a significant achievement as it is one of the largest and safest double hull tankers built in Germany. It was developed and built in close collaboration with the shipping company, German Tanker Shipping GmbH, and was built with class under the survey of Germanischer Lloyd and SeeBG, respectively. Together with the shipowner Lindenau worked to optimize the ship lines, to achieve an optimized load/volume relation at a maximum draft of 33 ft. (11 m) and PanMax breadth of 105 ft. (32.2 m). Line developments tested and proven by tank tests were intended to not only prove seakeeping and ice performance, but to optimize speed/power ratio to minimize fuel consumption. Much attention was paid to the development of a new fore ship, for the dual purpose of optimizing fuel consumption as well as ice-breaking performance. Compared to previous newbuildings, structural stresses on the fore ship were reduced by 40 percent according to the shipyard through the optimization of fore-ship lines. The cargo space of the ship consists of 2 x 5 cargo tanks as well as three slop tanks, separated from each other by volume longitudinal and volume transversal bulkheards, leading to smooth tank surfaces. The ship is equipped with a computer-based cargo monitoring and indication system ind the cargo control room, with the following functions: cargo- and slop-tank level indication with tank radars; cargo temperature indication and monitoring with three sensors arranged at different heights; cargo tank pressure monitoring with given alarms; manifold pressure monitoring with given alarms; and draft measurement system with four sensors. The electric-driven deep-well pumps enable a total cargo separation, very short discharge times of approximately 12 hours, and a high-efficiency tank washing system. The ship is equipped with an online-loading computer, which is connected to the integrated cargo monitoring and indication system,l as well as to the tank level measurement system for ballast and engine room storage and consumable tanks. The computer allows the crew to control online the longitudinal strength and intact stability during loading and discharging. For safety in navigation, the integrated bridge system is outfitted with two anti-collision radar systems.
