Currently, Ordinary Portland cement (OPC) concrete accounts for the world's 8-10% anthropogenic carbon/ greenhouse (GHG) emissions, where 90-95% of the emissions are due to the production of OPC. A 200% increase in OPC demand is projected by 2050 from 2010 levels. Therefore, it is urgent to reduce these emissions arising from its production....

Most of the waste glass, such as flat glass, glass bottle, is buried in the landfill, which is not desirable because it is not biodegradable and is not conducive to the long-term development of the environment. The glass powder (GP) with a certain fineness has excellent pozzolanic effect and can be used as a potential supplementary cementing...

In this paper, four kinds of ecological fine aggregates (manufactured sand, recycled sand, aeolian sand and river sand) were used to prepared UHPC, the effects of the fine aggregates on the workability, rheological properties and mechanical properties of UHPC were studied. The results reveal that the type and content of fine aggregate have an...

A QUAD lift is a new lifting method in which dual crane vessels combine their vessel capability to increase their offshore lift performance. The use of the Jumbo J-Class vessels in a QUAD lift creates the opportunity to increase the offshore lift capacity and to install structures with larger dimensions. When floating vessels are close to each...

The diversity of offshore structures is increasing nowadays, as more and more offshore structures are floating. To study the opportunity for Ampelmann to expand to the floating market it is necessary to see if working with floating structures requires a new way of operating. A potential market for Ampelmann is transferring maintenance personnel...

In this thesis the differences between the monohull and semi-submersible are investigated. For a general heavy lift crane operation and its operational profile, the difference is performance and total cost are calculated. These are used to determine the turning point, the point where the semi-submersible is more favourable for a heavy lift crane...

The engineering properties of alkali activated materials (AAMs) mainly depend on the constituent materials and their mixture proportions. Despite many studies on the characterization of AAMs, guidelines for mixture design of AAMs and their applications in engineering practice are not available. Extensive experimental studies are still necessary...

When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function as a fixed platform to which the crane is attached, therefore...

Traditional Ordinary Portland cement (OPC)-based concrete consumes large quantities of natural resources for its production, which is<br/>highly energy intensive and has high CO2 emission. Therefore, development of the geopolymer concrete, based on use of industrial byproducts,<br/>can provide an environmentally friendly and low-carbon...

The investigation into the dynamic behavior of a cable during installation was done with the aim of improving cable installation for safety, operational and commercial value. In order to increase the operational limit of the vessel during cable installation, the investigation into improvement systems was desired. The workability of a vessel...

In order for Jumbo to stay competitive in the offshore market, it's heavy lift vessels should be able to take on a wide range of lifting purposes. This can range from installation of transition pieces for wind turbines to installing modules of fpso's and platforms. One of the demands from the offshore market requires large lifting heights. It is...

This paper presents an investigation on workability and strength of geopolymer concrete made of fly ash (FA), blast furnace slag (BFS) and a multicompound activator of Na2SiO3 and NaOH solutions. The FA/BFS ratios were 100:0, 70:30, 60:40, 50:50, 40:60, 30:70 and 0:100. The workability of geopolymer concretes was performed by using slump test...

This report presents a method to calculate the frequency characteristics of a vessel that takes into account the dynamic interaction between the vessel and the Ampelmann system. Insight is provided into the dynamic interaction between the vessel and the Ampelmann system and the factors are identified that determine the changing dynamic behaviour...

The crew of the Razende Bol had experienced that their work conditions were worse than measured by the waverider. They concluded that the wave height measured by the waverider should be multiplied with a factor of 1.5 to find the real wave conditions in the working area. A number of reasons have been discussed, but only a hypothesis was...

The workability of floating construction equipment is one of the elements in the construction phasing of the design of the Ashdod port extension in the south of Israel by DHV Consultancy and Engineering. Waves play an important role in the workability of floating equipment, since they induce motions to floating equipment with the possibility of...

To support cost calculations for tendering a pipe lay project, the influence of weather conditions has to be incorporated by applying workability predictions for the pipe lay vessel. When assuming constant good weather conditions it is possible to accurately determine the duration of an offshore pipe lay project. In practice however, changing...

This study deals with the design of water management systems. Attention is focused on that phase in the design process in which variants are developed and evaluated with emphasis on the evaluation. The proposed evaluation procedure combines an economic evaluation with an evaluation of the hydraulic qualities- The economic evaluation implicates...
