Flood Rescue Boat as One of the Alternatives in Indonesia Waterways

2019

Flooding is the most frequent disaster that hit Indonesia, especially in big cities with poor urban planning. Infrastructure damage has occurred, the fatalities which are likely to occur, both during floods and after floods. So far, the fatalities caused by floods are very difficult to control and even tend to increase. This condition is getting worse with the lack of facilities that support the evacuation process of flood victims. The aim of the study was to design a lifeboat that was able to evacuate flood victims and be able to overcome other problems that might arise when the evacuation process runs more efficiently. By collecting data from several agencies related to flood mitigation problems, interviews with experts, as well as several other references, it is hoped that relevant data can be collected, which can provide solutions to the problems faced. The stages of the research included the creation of concepts and the design of a hull shape that was adjusted for a flood rescu...

Selected elements of the methodology and method of designing amphibious flood rescue vehicles

2012

The methodology of designing amphibious flood rescue vehicles at the preliminary stage of the design process has been presented. The study has been focused on the properties of such vehicles when afloat, with their on-land behaviour and performance characteristics having been left aside. In the study, a general assumption has been made that the amphibious flood rescue vehicles should be designed as, above all, watercraft that additionally can be driven on public roads and in off-road conditions. In the introduction, the solutions currently applied in the field of flood rescue transport facilities in Poland have been briefly defined. This has been followed by description of the methodology of designing amphibious flood rescue vehicles, supplemented with presentation of elements of the method of designing such vehicles that is based, firstly, on the assessment of vehicle performance and behaviour when afloat and, secondly, on the assessment of accident risk. The final part of this pap...

THE CONCEPTUAL DESIGN OF FLOATING HOUSE FOR POST-EARTHQUAKE TEMPORARY SHELTERS IN DIFFICULT LAND ACCESS AREAS IN INDONESIA

IAEME, 2019

Earthquake is one of the natural disasters that can occur in any country. As a result of earthquake, many residents lost their homes due to severe house damage. People are forced to evacuate to safer places and need temporary shelter immediately. In areas with land access damaged by the earthquake, the distribution of temporary shelters such as tents becomes difficult. For this reason, temporary housing that can be sent immediately even on damaged road conditions is urgently needed. One of the solutions to these problems is a floating house. Floating houses must be planned by fulfilling several requirements such as ease of mobilization, the buoyancy, stability, space sufficiency, the ability to produce its own energy and made from strong and durable materials. The results of this study produced a conceptual design of a floating house in the form of a reinforced concrete pontoon with a container house on top of it. This floating house has 4 beds and a storage cabinet. The electricity source is obtained from solar panels mounted on the roof of the container house. To maintain the stability of floating houses, anchors are used on all four sides of reinforced concrete pontoon.

Buoyancy and Stability Analysis of Ark’a Modulam Amphibious Foundation Model

Journal of Infrastructure & Facility Asset Management, 2020

To solve problems of settlement in floodplain areas, research on the anti-flood foundation model is crucial. The anti-flood foundation model should be able to float during floods and to remain on land during non-flood conditions. This research focused on an amphibious foundation model named Ark'a Modulam. The reliability of Ark'a Modulam floating construction was analyzed for buoyancy and stability against vertical and horizontal loads. Two floating constructions were designed based on knockdown and rigid systems. Both systems were designed using iron pipes with 2.5" and 4" of diameter. No significant differences were found in the buoyancy forces of the 2 floating construction systems. The load that can be supported by 1 floating construction was a maximum of 0.954 ton and stable at a floating depth limit of 43.2 cm. The stability of the floating construction should include the effect of vertical drive piles. The vertical and horizontal loads acting on the construction positioned inside Kahayan River during an extreme flood were also analyzed. During an extreme flood with 100 years of the return period, the construction of one vertical drive piles should able to support vertical forces equal to or larger than 7.50 ton

Emergency portable life raft product development

AIP Conference Proceedings

Inflatable life rafts, at present times are equipped on almost all passengers, fishing and commercially operated vessels. Universally, life rafts are the first mode of evacuation system, be it a fishing boat with relatively small crew to an outsized passenger vessel with more passengers and crew. In an event of a natural disaster such as floods happening in any kind of region be it sparsely or densely populated areas where rescue and evacuation operations can be hard to reach, people will be often left to look after basic survival exigency. We have developed an emergency portable life raft which is seamless and compactly integrated to a backpack which weighs merely 2.5 kg. During the flood, victim can instantly respond by packing up with survival necessities. The portable emergency life raft aims to provide a versatile, userfriendly and an all-round solution for the survival endurance during floods.

Morphological Decision Making for Amphibious House Platform as a Sustainable Flood Protection Strategy

Proceedings of the National Academy of Sciences, India Section A: Physical Sciences, 2018

The concept of amphibious houses has a broad range of application as a sustainable and multi-reason solution for flood protection. Based on the current materials and methods for implementation of the amphibious house, an optimal morphology is required to be achieved. Different morphologies for the buoyant component should be evaluated under four classifications towards sustainable development. This study evaluated the best design and material for floating part in amphibious houses based on technological, environmental, economic, and social classifications. This study applied the multi attribute decision making model using relevant criteria for applying amphibious house as a flood protection strategy in floodplain areas in South-East Asia. The bucket system (pontoons) which is made by lightweight concrete and using expanded polystyrene block inside is identified as an applicable morphology for buoyant part in amphibious houses.

Damage stability analysis in particular flooding situations of a multipurpose cargo ship

IOP Conference Series: Materials Science and Engineering, 2018

Flooding of ship compartments is a very common event resulted from ships involvement in marine accidents, such us collision, grounding or structural breakdown. Once ship compartments are flooded to an extended level, the transverse stability starts to be affected and if the situation become dangerous, it can become critical or failing beyond the lower threshold values. In this damaged situation, a proper and accurate calculation and assessment of stability is very important. Calculation of damage stability for flooding situations is a very important subject for those who work in design and operation of ships. However, the subject was treated extensively in respect of tanker ships and less in respect of multipurpose cargo ships. The aim of work presented in this paper is to highlight some particular situations of flooding of compartments on board a multipurpose cargo ship when the stability parameters are decreasing enough so that fails to comply with recommended criteria. The particularity of the study for this type of ships came from the fact that are fitted with large box type cargo holds which in case of flooding are generating large free surface effects with a high negative impact on ship's stability. Thus, four situations of flooding are presented and the analysis of stability parameters are illustrated in line with the actual regulations, in respect of damage stability, established by international conventions. Based on the results of calculations, the study gives recommendations regarding the actions to be taken in order to limit the dangerous consequences of such situations. The results of the particular flooding situations presented can be used to continue the improvement of design and operation for this type of ships.

Flood Mitigation Measures -Design of an Amphibious House

Natural disasters have caused a lot of damage and destruction throughout the world. A major natural catastrophe among all the disasters is flooding. Flooding is very common in India as India is one of the most flood-prone countries in the world with almost 30 million Indians getting affected on an average annually. India's average economic losses due to natural calamities are estimated at INR 746.83 billion, of which over INR 532.94 billion are attributed to floods. Along with financial and real-estate losses, it also causes emotional damage to people. To minimize these losses, we thought of different Flood mitigation measures and chose to further work on Amphibious housing. Amphibious houses are the structures that majorly work on two principles i.e. Archimedes Principle and Pontoon principle. So, these houses act like normal houses but when a flood occurs, it rises to the height of flood level and floats with the help of pontoons or hollow basements. It is supported by the vertical mooring poles to avoid displacement due to external forces. Once the floodwater is drained off, the house comes back at rest to the ground level. For making the houses float, the foundation or the sub-structure is made up of Expanded Polystyrene Foam (EPS) blocks. While the superstructure can be made using different materials like timber, EPS blocks, lightweight concrete, Ferro cement, etc.

Criterion of vehicle stability in flood-waters based on theoretical and experimental studies

Natural Hazards, 2014

Vehicles parking on streets or roads can cause various hazards to people and property when they are swept away by urban floods. It is therefore appropriate to investigate the criterion of vehicle stability for such flood conditions, especially for different scenarios and where the criterion of vehicle stability is usually represented by the incipient velocity for the vehicle. In the current study, different forces acting on a partially submerged vehicle are outlined, together with the corresponding expressions of these forces, and a mechanics-based formula of incipient velocity is given for partially submerged vehicles under different orientation angles. About 200 runs of flume experiments were conducted to obtain the conditions of water depth and corresponding velocity at the threshold of vehicle instability for three orientation angles, using two types of die-cast model vehicles at two model scales. Experimental data obtained from the large-scale model vehicles were then used to determine two parameters in the derived formula. Finally, incipient velocities for three vehicle orientation angles were estimated using two different approaches, including predictions using the scale ratios from the small-scale model vehicles and computations based on derived formula using the prototype vehicle parameters. These critical conditions for the prototype conditions, based on the scale ratios, compared well with the calculations obtained using the derived formula, which guaranteed the predicative accuracy of the formula. In addition, the effect of different ground slopes on the vehicle incipient motion was also investigated, using similar experiments and based on the theory of similarity, which indicated that the incipient velocity for a small passenger vehicle on a ground slope of 1:50 was about 25 % lower than the value on a flat ground for an incoming depth of 0.25 m.
