HMD and DNV GL present world’s first double side hull LPG carrier At the Gastech 2017 conference
in Tokyo, DNV GL presented Hyundai Mipo Dockyard (HMD) with an approval in principle (AIP) certificate for a new double side hull LPG carrier design – LPG SAFE (Structural Advances for the Environment).
The result of a development project conducted by HMD working closely together with DNV GL, the AIP certificate confirms that the design complies with the new DNV GL rules for the classification of ships. The innovative LPG SAFE design is the first 38K LPG carrier design to provide the safety benefit of a double side hull, while offering the same cargo carrying capacity and the same construction cost as a conventional design.
LPG carriers are designed to carry liquefied gases such as propane or butane in bulk. The ships are normally equipped with cargo tanks inside the hold, with Type A independent cargo tanks arranged inside the hold, supported on insulation-bearing blocks which typically consist of wooden chocks installed on the inner bottom structure. The double side hull design of LPG SAFE offers a significant increase in protection for these tanks, especially in the event of a collision.
New fish farm specialist workboat by Tuco
Danish composite vessel specialist builder, Tuco, has introduced a new 14.99m catamaran workboat specifically for the fish farm market.
The boat’s hull requires lower maintenance since it is built from composite materials, which guarantees very high strength and minimal weight. According to Tuco construction with high strength and low weight allows not only high performance and speed but also reduced operational costs. Furthermore, the ballast tank system enables the use of cranes with a capacity that exceeds the standards for this class of boats.
The boat is designed for the fish farming industry where it will serve as a platform for work and crane operations. The unique construction has been tailored to fit the tasks in the industry and allows for heavy lifting. The tasks are diverse and include for example replacement of nets, feeding, underwater inspection, research, dredging, installation, repair and maintenance of structures.
The 14.99 metre ProZero catamaran is equipped with a ballast tank system in order to supply the inherently light vessel with the weight and hence stability necessary to counter any imbalances that may occur during heavy lifts at the breeding facilities. The heavy work includes replacement of nets on smaller cages and handling of heavy equipment. By utilizing the ballast system, the weight distribution can be easily adjusted to obtain the necessary stability. The operation takes just 6 minutes and the boat is ready for lifting.
