This chapter examines the bureaucratic problems that would imperil the floating pool's opening at the last minute. It cites Steve Sivak, who returned from Ann Arbor to crack the whip during the last critical weeks of work on the floating pool, obtained last minute materials, and answered questions from subcontractors as rapidly as possible. It also mentions the city agency that considered the hybrid barge a structure and not a boat, requiring the author to get a building permit. The chapter recounts Maritime engineer Malcolm McLaren, who designed the mooring system and determined that anchors could be deployed more quickly than spuds. It analyzes the suitable water depth that made it easy for the floating pool to depart and return to the site by tying the barge to anchors already in place.

The Aasta Hansteen spar in the Norwegian Sea is designed to be moored with a taut polyester rope mooring system. The water depth at the field is 1300 meters, and due to the short installation season the most efficient hookup is with pre-installed mooring lines, which require the mooring lines to be laid down on the seabed. DNV certification does not allow seabed contact for polyester ropes unless proven that no soil ingress and damage takes place. To be able to certify the ropes Statoil developed a test method including contact with soil, rope movement and forced water flow through the filter construction. Full scale tests were performed with actual rope and Aasta Hansteen soil, both in laboratory and at site. This paper discusses the certification requirements and presents adequate qualification test together with results from testing.

Petrobras developed a new kind of anchoring device known as Torpedo. This is a steel pile of appropriate weight and shape that is launched in a free fall procedure to be used as fixed anchoring point by any type of floating unit. There are two Torpedoes, T-43 and T-98 weighing 43 and 98 metric tons respectively. On October 2002 T-43 was tested offshore Brazil in Campos Basin. The successful results approved and certified by Bureau Veritas, and the need for a feasible anchoring system for new Petrobras Units in deep water fields of Campos Basin led to the development of a Torpedo with High Holding Power. Petrobras FPSO P-50, a VLCC that is being converted with a spread-mooring configuration will be installed in Albacora Leste field in the second semester of 2004. Its mooring analysis showed that the required holding power for the mooring system would be very high. Drag embedment anchors option would require four big Anchor Handling Vessels for anchor tensioning operations at 1400 m water depth. For this purpose T-98 was designed and its field tests were completed in April 2003. This paper discusses T-98 design, building, tests and ABS certification for FPSO P-50.

Design Requirements

The design of a mooring system for tension leg platforms (TLPs) becomes more complicated as water depth increases. The use of steel mooring lines requires complicated tensioning, handling, and flotation systems. This paper discusses the basic design requirements for the TLP mooring system and identifies several advanced fiber-reinforced lightweight materials as alternatives to steel. High-modulus carbon fiber/KevlarcircleR fiber hybrid composites and Kevlar ropes appear to offer the optimum mooring systems for TLPs used in the development of large and medium-size reservoirs, respectively.

Abstract This paper presents a parametric design study of the mooring system for a floating offshore wind turbine. We selected the OC4 DeepCwind semisubmersible floating wind turbine as the reference structure. The design water depth was 50 m, which was the transition area between the shallow and deep waters. For the floating wind turbine working in this water area, the restoring forces and moments provided by the mooring lines were significantly affected by the heave motion amplitude of the platform. Thus, the mooring design for the wind turbine in this working depth was different from the deep-water catenary mooring system. In this study, the chosen design parameters were declination angle, fairlead position, mooring line length, environmental load direction, and mooring line number. We conducted fully coupled aero-hydro dynamic simulations of the floating wind turbine system in the time domain to investigate the influences of different mooring configurations on the platform motion and the mooring tension. We evaluated both survival and accidental conditions to analyze the mooring safety under typhoon and mooring fail conditions. On the basis of the simulation results, this study made several design recommendations for the mooring configuration for floating wind turbines in intermediate water depth applied in China.

Overpass is the major transportation facilities in the city, and occupies a very important position in the urban road network. Rainfall can likely cause surface water under the concave overpass. We establish a concave overpass wanter depth monitoring sandbox based on Internet of Things, and simulate the concave overpass water depth with different rainfall level. Simulation results show that the concave overpass wanter depth monitoring sandbox can control the overpass water depth with controlling drainage opening time by adjusting the threshold value, and simulate the physical environment very well. This can interchange for the city flood control and drainage design, checking provide reference and basis.

Heavy Rains

The year 2016 marked the fifty-year anniversary of the tragic and destructive flood in Florence, Italy. The floodwaters shook the world with their indiscriminate destruction of human life, property, and priceless Florentine cultural heritage. Early in November of 1966, days of heavy rains transformed the Arno River into a raging beast, overflowing its retaining walls and submerging much of the city and the area around it in foul, murky water filled with sediment, vegetation, sewage, motor oil, and the flotsam of human civilization. The floodwaters either destroyed or badly damaged historic collections of art, sculpture, architecture, books, manuscripts, and documents stored in low-level galleries or basements of institutes, libraries, museums, and private residences.

ABSTRACT Depok is a city that is directly adjacent to the State Capital Jakarta. We know the city very narrow and very expensive housing land, the people’s choice is certainly suburb of the city that faced Depok. People in the sense of disappointment in the management of IMB, ranging from problems of slow and obscurity until the problem. convoluted procedure is coupled with process information that is not clear and always float, eventually the certainty of always not found. This research conducted with qualitative methods, collecting data through interviews, observation and in-depth discussions with informants who are directly related to the issuance of IMB service process, from the entire city of Depok regional organizations involved in the publishing process IMB. The results showed that the application of Electronic Government in the process of publishing Building Permit (IMB) in Depok in West Java has not applied thoroughly and with a system that has not integration. Implementation of Electronic Government in the work units involved in the process of IMB also yet thoroughly and also not maximized in the improvement of work processes (Business Process reengineer). Information Technology applications and infrastructure used in the process of issuing building permit was not optimal in helping the process of IMB. This study also shows the weakness of the role and functions of the organization which accountability in the application of information technology, lack of commitment in the implementation of electronic government, the difficulty of doing business systems integration services network IMB).

New Criteria

The city of Curitiba-PR has a municipal decree that establishes the criteria for the design of flood detention tanks. However, these guidelines do not guarantee minimum efficiency during operation, as it may vary depending on their base area, water depth and flow regulating orifice diameter. In this research, a design method was proposed, establishing some new criteria that relate impervious areas of the lots to the tank design parameters. The efficiency definition was established with the premise that the tanks should provide the return of flows from an impervious area to its pre-urbanization scenario. This reduction was established as 70% of the peak flow in the city of Curitiba-PR. Based on simulations of flow routing with the Puls Method, the optimum geometric characteristics (volume, area, water depth and orifice diameter) of the tanks were obtained to guarantee the decrease in the peak. Comparing the results obtained from the municipal legislation design, the new method provided n minimal efficiency and a decrease of 24% of the tank volume.
