Pipe-lay vessels, heavy-lift crane vessels and dual purpose heavy-lift and pipe-lay vessels are distinct in many ways from other types of ships or offshore units. The unique functions that these vessels carry out can impact directly on the overall safety of the vessel, the personnel on-board and the potential to pollute the environment. This paper outlines some of the hull and machinery safety assurance considerations for classification and design pertinent to pipe-lay and heavy-lift operations. The considerations that are discussed in this paper include the implications of classing the vessel as a ship or an offshore unit; the interaction between classification and marine warranty; general arrangement; station-keeping; structural assessment and the interaction between safety critical systems. Specific hazards for pipe-lay vessels and their use of chemicals on-board are also discussed.

Abstract Elevated service reservoir is one of the maximum important infrastructures that is utilized by society. Our every day existence relies upon at the water supply, that is procured through an elevated service reservoir. Therefore, the safety of the service reservoir is of utmost importance. Most of the damage on elevated service reservoirs is caused by an earthquake, as the horizontal forces acting on the structure make the service reservoir vulnerable. Our predominantly study is based on extracting the dynamic forces mainly to determine critical condition of the structure. In this paper, different capacities of elevated service reservoir are taken and the design and analysis are done according to Indian standards. Dynamic analysis of the service reservoir is done and parameters such as time period, hydrodynamic pressure, base shear, base moment are compared with different capacities. Hence, the capabilities of the structure are substantially necessary to examine within the sub-continent region.
