design criteria for specialized ships

This standard establishes the general design criteria and associated tests for specialized shipping containers used by the Department of Defense. It is also important to know how to utilize the power of social networks to transfer this knowledge. Design Criteria • Depending on the type and mission of the ships, during the initial design stage several design criteria can be used to evaluate specific aspects of the ship performance: – Intact Stability – Damaged Stability – Dynamics –Maneuverability yt i l ibat sesru–Co This standard is intended to be used as the basic reference This document provides a simple introduction to … If criteria and requirements included in this Guide are satisfied, ABS may assign an optional class notation and social network-related findings are applied. In this environment, project work is the norm, and responsiveness to frequent technical changes is critical for performance. Specifies the dimensions, design and construction, materials and quality of finish for steel dog-step ladders formed from a series of shaped rings welded to the ships' structure.These ladders are intended for use in trunks, deep tanks, cargo oil tank bottoms, etc. containers used by the Department of Defense. Burt, R.S., 2005, “The Social Capital of Structural Holes” in Mauro F. Guillen and Randall Collins (Ed. Figure 1: Comparison of the expected total costs of the reactive (deterministic) and proactive (stochastic) strategies. This Section considers the design of the ship lines and body plan (see Figures 3.2 and 9.44), and the modification to form. Figure 3: The multi-method approach to design uncertainty in shipbuilding planning. To connect the element of design to project scheduling, in one stochastic-dynamic program, to study the impact of design uncertainty on planning. Katzenbach, J. R., Smith, D. K., 1993, “The wisdom of teams: Creating the high-performance organization,” Harvard Business Press. WBDG is a gateway to up-to-date information on integrated 'whole building' design techniques and technologies. Such an industrialization process is the scope of the current change program at VARD, with a focus on reorganizing the engineering department to better align with the existing social capital while creating lean processes. As such, this Standard should be used in conjunction with B30.20, which addresses safety requirements.

Energy Efficiency Design Index (EEDI), formulated for new ships, is an index that estimates grams of CO 2 per transport work (g of CO 2 per tonne‐mile). B. Ships and marine technology — Ship recycling management systems — Guidelines for selection of ship … This is exemplified by Figure 1 for increasing probability of design alternative B (i.e.,  decreasing belief in the originally assumed design alternative A). In this change program, both the O.R. Social ties are particularly critical when tacit knowledge constitutes a large share of the available resources as it is in many organizations with long traditions. According to the International Code on Intact stability, 2008, the following criteria are mandatory for passenger and cargo ships constructed on or after 1st January 2010: 1. In the great days of sail, vessels were designed and built on the basis of practical experience; ship construction was predominantly a skill. Hajnalka Vaagen is a senior scientist with the SINTEF Technology and Society, Dept. The results indicate high value of flexible hedging strategies (proactive strategies) that capture the value of future design changes. Given that, planning and scheduling large, complex projects normally requires advanced decision support tools, and operations research is expected to play a vital role in this task. The social-behavioral approach uncovered high-performing groups and their ability to achieve synergies to handle technical changes in shipbuilding projects. Definitive requirements for specific containers will be defined by Dealing with the described complexity judgmentally is, however, not less complex, even when the large number of behavioral issues that may negatively affect the outcomes (limitations in working memory, incentive misalignment, invisible and illusory correlations, just to name a few) are “ignored.” In spite of this, the organization of shipbuilding projects at VARD demonstrates a high level of responsiveness and innovative solutions to quickly adapt technical changes throughout the construction processes. The results trigger increased focus on the social interactions and behavioral reactions to handle technical uncertainty in typical engineering environments. A methodology for reliability-based design of ship structures is provided in this document. The NextShip project results are not a single tool or model, but rather a collection of (and cautious use of) various tools, approaches and insights, all focused on handling the design problem in planning to improve project flexibility and responsiveness. approaches to project planning and scheduling in two distinct directions: A. preparation and revision processes. The goal of 'Whole Building' Design is to create a successful high-performance building by applying an integrated design and team approach to the project during the … Design principles—Instruments belonging to separate essential processes shall be independent. Lifting Criteria . Initial contextual studies point to “team abilities to share experience” and “tacit knowledge” as the drivers of responsiveness to changes. This enables finding good plans in the future without actually solving complex stochastic models. The multi-method approach extends the scope of research on classical O.R. apprOach tO ship structural design which has served the designer, builder and operator well through the years. Design uncertainty is the major driver of planning complexity in building specialized vessels used in offshore oil and gas exploration. Navy ship design is a complex process for a complex product used for National defense. 9.2.7. Applied Economics and Operations Research, headquartered in Trondheim, Norway. The role of O.R. vi. Military Sealift Command MSC Ship Ventilation Design Criteria . Kahneman, D., Tversky, A., 2000, “Choices, Values and Frames,” Cambridge University Press. Finding a way to formulate this stochastic dynamic scheduling problem is very difficult or even impossible for large projects [4], mainly because the order of decisions is not fixed but depends on previous decisions and the realization of random variables [6]. The planning complexity with stochastic changes in design specifications is approached by small model instances, with the aim to learn what it is that makes solutions good. The development of reliability-based design criteria for surface ship structures needs to consider the following three components: (1) loads, (2) structural strength, and (3) methods of reliability analysis. PACK - PACKING, PACKAGING, PRESERVATION AND TRANSPORTABILITY. Emblemsvåg, J., 2014, “Lean project planning in shipbuilding,”, Jørgensen, T., Wallace, S. W., 2000, “Improving project cost estimation by taking into account managerial flexibility,”. These aspects, connected to extensive grade of tacit knowledge, in a flat organization that delegates decisions to lower levels, facilitates the development of high-performance teams, where people feel collaborative (positive) pressure to find immediate solutions to unplanned changes. The design of the ship's lines is fundamental to the ship design process. This potentially improves the outcome of judgmental decision processes. MIL-STD-648D, DEPARTMENT OF DEFENSE DESIGN CRITERIA STANDARD: SPECIALIZED SHIPPING CONTAINERS (10 APR 2008)., This standard establishes general design guidelines and associated tests for specialized shipping containers used by the Department of Defense. An integrated system shall be arranged with sufficient redundancy to prevent loss of essential functions upon a single failure. In social sciences, human relations and the value these relations have in sharing information, knowledge and resources define the social capital, which is quite often associated with enhanced innovation. These patterns exhibit different influences, behaviors and choices. Simulation-based planning approaches may also benefit from the knowledge on what solutions structures should be investigated; particularly, when a full scenario tree evaluation is not possible due to the size of the problem. The design criteria set forth are minimum requirements that may be increased at the discretion of the lifting device manufacturer or a qualified person. “Built on trust” is the motto of the VARD Group AS, one of the most innovative global designers and builders of specialized vessels used in offshore oil and gas exploration. CIENG consists of a highly qualified staff of engineers and architects responsible for the technical adequacy of all Navy shore facilities design, construction, and maintenance criteria. 2. 5-12-9 (New) Safety Requirements . provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD(AT&L) Memorandum dated 29 May 2002. Marine Structural Design, Second Edition, is a wide-ranging, practical guide to marine structural analysis and design, describing in detail the application of modern structural engineering principles to marine and offshore structures.. ), “The New Economic Sociology: Developments in an Emerging Field,” The Russell Sage Foundation. Despite being located in Norway – a high-cost country with suboptimal infrastructure and employment conditions – the company ranks among the best in terms of flexibility, delivery precision and short delivery times at competitive prices. The research demonstrates more than 35 percent cost reduction when applying proactive strategies compared to reactive strategies, where static (deterministic) plans are updated in light of new (design) information. However, because there is a “but” when uncertainty-handling is largely based on social interactions, it is not enough to know the right answer to what makes solutions good. The relational patterns are visualized, hypothesized and tested statistically [8]. Vaagen H., Kaut M., Wallace S.W., 2015, “The impact of design uncertainty in engineer-to-order project planning,” under review. Specific Ship Ventilation Design Criteria (CAC-Enabled Content). cannot be ignored, though, as without analytical guidelines, a new improvement idea might fail. The selection of materials and member type, size, and configuration to carry loads in a safe and serviceable fashion. This actor connects the otherwise disconnected heterogeneous groups of project managers and technical coordinators (the two key functions in a project organization). Kall, P., Wallace, S.
