An Act to provide for the safety, health and welfare of persons on installations concerned with the underwater exploitation and exploration of mineral resources in the waters in or surrounding the United Kingdom, and generally for the safety of such installations and the prevention of accidents on or near them. [27th July 1971]

The purpose of the paper is to evaluate the feasibility of implementing a tracking based inventory management system in temporary storage locations of a project delivery chain. To describe the use of tracking based inventory information for improved logistics control in equipment delivery and installation.

A solution design experiment was carried out in 16 temporary storage locations with one original equipment manufacturer and four installation partners.

It is feasible to implement tracking based inventory management in temporary storage locations. The challenge is to ensure that installation partners adopt the system. The benefit is improved logistics control of equipment delivery and installation for the original equipment manufacturer.

Tracking information is more useful than conventional stock keeping in project delivery. By monitoring the dwell time of delivery items it is possible to identify and resolve problems in project execution.

Inventory management in temporary storage locations help project management, project logistics, and central logistics organizations carry out their work more effectively. Implementation can be based on tracking.

The paper's value lies in empirical tests and evaluation of tracking based inventory management in temporary storage locations.

The aim of the research is to determine the influence of photovoltaic (PV) installation and the share of façade glazing on the energy profile of nursery buildings in the Baltic Sea region, as well as defining the most favorable configuration in terms of energy efficiency.

The article provides comparative calculations of energy performance indicators (Ep, Ed, Eu) and CO₂ emissions (mCO₂) made for the defined model of the nursery. It includes calculations concerning energy performance of the building, depending on its PV power (0–60 kWp), PV efficiency (100 and 85%) and façade glazing ratio (GR = 25%, 50% and 75%).

The results of the research indicate that an increase in the PV power exerts proportional impact on the reduction of the Ep and Ed indicators, as well as on the CO₂ emissions. Only low GR values (25%) reduce the Eu indicator significantly. Decrease in high range of GR values (over 50%) does not provide proportional effects. In the variant: 60 kWp (100% efficiency) with GR = 25%, the biggest share (99.5%) of RES was obtained. This proves that the concept of energy independent nursery buildings is feasible and reasonable in the examined location.

Designing buildings towards environmental neutrality requires laborious pre-design conceptual work before developing the right solutions. The set of results of the relationship between the variables of the building's envelope, energy performance indicators and the required involvement of active RES installations to achieve high energy performance of a building presented in the article is valuable. It allows for a preliminary decision of the direction of the design solutions selection in the design process of public utility buildings, such as nurseries. Thus, it may significantly shorten the pre-design analysis process for the location of the southern part of the Baltic Sea region.

The novelty of the paper relies on examining the dependences between PV power and façade glazing ratio in terms of their influence on energy profile of nursery buildings.

Any electrical installation which is designed correctly, installed to a good standard of workmanship and maintained regularly should give many years of trouble‐free service. This paper assumes that the first requirement has been met and sets out the inspection and test procedures which are considered necessary to ensure that the two latter requirements are also satisfied. It is, however, concerned only with installations not exceeding low voltage.

Prominent figures in the Information Systems (IS) industry have been propagating the need to integrate the information systems plan of a company with its strategic business plan. They have urged the executive level management to take an active part in charting the role of Information Technology (IT) in their organisation's present and future operations. The primary reason for this has been that the cost of data processing and communications has reached a critical level. A multi‐million pound operation cannot be run without executive systems direction and control. Without a common source, planning, implementation and measurement and control between various levels of management will be meaningless. Despite this, the management approach remains largely tactical, expense‐oriented and short‐sighted. Structures for strategic management of information systems and associated facilities have not yet clearly emerged. In an information systems environment, strategy implies plans, policies and commitment to use IT for exploiting business opportunities in order to achieve the corporate goals of an organisation. Because corporate objectives data, financial and budget data, resource usage, together with service and installations inventory data and personnel data already exist in computer‐readable form for large installations, this makes it easier to implement a computer‐based strategic installation management system.

In the Norwegian oil and gas industry the upstream logistics includes providing the offshore installations with needed supplies and return flow of used materials and equipment. This paper considers a real‐life routing problem for supply vessels serving offshore installations at Haltenbanken off the northwest coast of Norway from its onshore supply base. The purpose of the paper is to explore how the offshore installation's limited storage capacity affects the routing of the supply vessels aiming towards creating efficient routes.

A simplified version of the real‐life routing problem for one supply vessel is formulated as a mixed integer linear programming model that contains constraints reflecting the storage requirements problem. These constraints ensure that there is enough capacity at the platform decks and that it is possible to perform both pickup and delivery services.

The model has been tested on real‐life‐sized instances based on data provided by the Norwegian oil company Statoil ASA. The tests show that in order to obtain optimal solutions to the pickup and delivery problem with limited free storage capacities at installations, one has to include in the formulation the new sets of constraints, the storage feasibility and the service feasibility requirements. In addition, two visits to some platforms are necessary to obtain optimality.

The main limitation is the present inability to solve large cases.

The contribution of this paper is to provide a better insight into a real‐life routing problem which has a unique feature arising from the limited deck capacity at the offshore installations that complicates the performance of service. This feature has neither been discussed nor modeled in the vehicle routing literature before, hence the formulation of the problem is original and reveals some interesting results.

The purpose of this paper is to identify and discuss various factors that will influence the process of installing and maintaining subsea equipment in the oil and gas (O&G) industry.

Influencing factors and their attributes are identified using a case study on subsea installations conducted in the Norwegian O&G industry. A number of experts were interviewed. A survey was conducted to rank the importance of the influence factors.

The paper identifies, analyzes and validates the factors and attributes that may impact the installation and maintenance strategy of subsea components. The factors are ranked according to importance and as practiced in the industry.

The research is based on a case study in the Norwegian O&G industry, but the approach and results could be adapted to other industries as well.

The identified factors can be used by decision makers in the development of offshore projects.

Properly planned module installation on an industrial site is a critical factor in delivering a project safely, on time and within budget. Different sizes of heavy-duty mobile cranes are used to pick, swing and place the modules. Crane selection depends on module size and weight, as well as crane availability, location and configuration. Weeks can be spent in trial and error to prepare and improve module installation plans due to the large number of ways to install the modules on site, high crane operating costs and other crane-module constraints. A tool to automatically generate module installation plans is essential.

This paper presents a novel heuristic-based methodology for planning and sequencing module installation on industrial construction sites that takes into account proposed technological constraints.

Case studies are presented to demonstrate the ease and effectiveness of the developed methodology in planning module installations.

On a complex project, the tool can save time in preparing the installation plan, while also reducing the amount of crane supporting tasks (foundation preparation and crane movement).

The purpose of this paper is to present an approach for measuring the ability of oil and gas production plants to utilize shutdowns opportunistically for maintenance.

Key performance indicators have been developed from case studies with two offshore oil and gas installations on the Norwegian Continental Shelf. The key performance indicators measure the quality of the work preparations and the ability to utilize shutdowns opportunistically. Shutdowns may provide opportunities for execution of maintenance, but it is hardly possible to undertake any maintenance work requiring shutdown if the organization is not well prepared and the work is not well planned.

The results from testing of the indicators on two oil and gas installations shows that several of the indicators are relevant for determining the quality of preparations, whereas more effort needs to be put into gathering data applicable for monitoring the actual utilization of the shutdowns.

Production losses, due to turnarounds and unforeseen shutdowns in oil and gas operations, are significant, and the improvement potential is large. The indicators may assist maintenance managers in planning and improving the plant's utilization of shutdowns and may contribute to substantial cost savings.

The approach in the paper adds important knowledge on how to actually measure the quality of maintenance work planning and execution.

This paper aims to analyze efficiency of the subsidies granted by the Spanish authorities. The case study focuses on wind-generated electricity. We will study what type of subsidy is most efficient considering the economic and technical data of an existing wind power installation in Spain. A sensitivity analysis is made in order to provide judgment elements to propose the form of the more convenient subsidy. In view of the results obtained, we will evaluate the efficiency of subsidies granted by Spanish authorities.
