abstract = {Many times, items are listed as 'Items to Deduct' during the Deadweight Survey, which, according to the Expanded Ship Work Breakdown Structure (ESWBS), are actually part of Lightship. Due to misconceptions and/or errors, the Deadweight Survey is not accurate when compared to the Mass Properties Reports. The largest confusion is with the definition of Operating Space Items (OSI), Storeroom Items (SRI), and General Use Consumable List (GUCL) items. Another issue is that OSI is most often completely missed in the early stages of a weight estimate and those items are also among the most challenging to get accurate weight values for. Weighing of these items is difficult as these are generally small items and have a high risk of being pilfered or 0damaged, and are therefore not loaded out until delivery. Although arriving late in the weight estimating schedule, getting accurate weights for the 'little things' that make the ship work will benefit the Deadweight Survey / Inclining Experiment, and will also yield valuable data for future parametrically generated weight estimates. This paper shows one method used to accurately capture the weight and the locations on the ships where these items will be.},

abstract = {Weights engineering feeds into hydrostatic trim and stability analysis and hydrodynamic analyses of many sorts. It is an important task that requires attention to detail and hours spent carefully reviewing drawings and manufacturers cut sheets to develop data at the necessary level of detail. What do you do when the ship was built far in the past and few or no drawings exist? What if there are a few drawings and references but they conflict on critical details? Will we ever be able to do an adequate weights analysis? This paper describes several such analyses and the detective work and re-engineering that has gone into developing reasonable weights and centers information for these historic vessels. These analyses were used to support sinking analyses in several cases and the problem is significantly different for a wooden vessel than a iron or steel vessel. The just-submerged analysis is significantly different from the surface analysis. Many tricks of geometry and integrating the results from different software can be used to further the understanding of the missing data.},

ESWBS is a functional classification system that is used for weight reporting purposes. It is used on all USN ships as well as many other shipbuilding programs as a method by which all weight estimates are functionally organized. Also, ESWBS is used as an aid to developing ship cost estimates. With the introduction of newer technologies, materials and constructions practices in ship designs, the proper weight accounting has become more difficult and somewhat subjective. Therefore, this paper provides guidance and clarification on the proper weight classification of elements in a weight estimate with a focus on the newer technologies and practices.},

It has been assumed that the large dead weight of an FPSO makes the design insensitive to variances in mass inertia over the design cycle. As hydrodynamic engineers improve their mooring design performance and reduce margins, minor changes in mass inertia can have dramatic impact on system response. This paper will compare the mass inertia estimating, uncertainty and detailed calculation with mooring performance to determine optimum thresholds for weight control to mitigate the risk of changes in inertia.},

After the weight process is thoroughly explained, an analysis and recommendations of the overall method are given. Finally a proposal to create an accurate weight estimate for the Rushmore Project is offered. In this proposal the suggestions outlined are to (1) create a detailed weight estimate spreadsheet, (2) keep all weight estimate documentation up to date, (3) request machinery and wiring weight information from the shipyard, (4) request the shipyard weigh the vessel frequently throughout the construction process, and (5) create a relationship with the interior design team to create accurate joinery weight estimates.},

The submarine design is unique in that the center section design is more mature than the rest of the boat. Because of this a simulation was created to study the margin usage during early stage design, through design and construction, and up to delivery. The simulation provided data to support the selection of separate center section and whole boat margins based on certainty levels and optimistic, neutral, and pessimistic outlooks. The results of the study show that margin usage correlates highly with initial margin values, that variations of the initial center section margin affect the remaining margin less than the initial boat margin, and that the initial margin goals may have been set higher than necessary. The paper concludes with recommendations for initial margin amounts.},

abstract = {In every ship design weight engineers are challenged with estimating the weight and center of gravity for stowage aides and stowage contents particularly in the pre-contract stage of ship design. Ratiocination techniques using parent hull designs contained in SAWE Weight Engineers Handbook (SAWE, 1986) will suffice at the concept phase of design, but as the design progresses a weight engineer requires higher fidelity information for storeroom location and function, types and number of stowage aids within a storeroom, as well as the number of lockers and special stowage aids scattered throughout the ship. Hull outfitting design and construction products for stowage aids are typically scheduled for issue after primary hull structure and major through services and equipment arrangements have been established. Also, the list of items to stow is not provided until very late in the design. As a result this portion of the reported ship weight and center is usually neglected by the weight engineer due to the perceived lack of information and realization that 'stowage' accounts for only approximately one percent of the lightship weight and one percent of the load weight. Yet, most weight engineers are unaware of an abundance of information available mainly due to their lack of knowledge in the ship design and storeroom and stowage aid design process. 

This paper in meant to enlighten the marine weight engineer in a process used successfully for evolving the estimates and calculations for stowage aid and contents weight and center of gravity from the early to latter phases of ship design.},

abstract = {Design tools have made significant progress since the days of drafting boards and T-squares. Today's advanced 3-D product modeling systems offer tremendous capability in both design and analysis. However, the same capabilities that benefit the ship designer are usually not optimized for the mass properties engineer or weight calculator who must extract data from the product model to determine weights and moments for the marine product in question. In the marine field, the identification of functionality to support the mass properties function is developed each time a new design system is deployed and often gets much less attention than the design function. Because new design tools are usually not developed specifically for the marine industry, extensive customization including mass properties functionality is generally required for each marine application. No industry standard exists for the basic functional requirements which a new design tool should satisfy. This paper will attempt to define core functional requirements needed by mass properties engineers in the marine field. It is hoped that this effort will allow the mass properties engineer faced with the advent of a new design tool to dedicate more time in the future to the unique or specialized features desired rather than the core mass properties requirements that should be met by all advanced design tools.},

abstract = {This paper documents the analysis of simulation-based submarine roll data pursuant to the development of new submarine stability criteria for the transition between submerged and surfaced conditions. A matrix of ship, environmental, and simulator conditions was developed resulting in 137 different run conditions, each of which was repeated 50 times for a period of 200 seconds at a sample rate of 1Hz. This resulted in 6850 data files and 1.37 million data points for each of the seventeen channels of data recorded (e.g., speed, depth, roll, pitch). The data was processed semi-automatically through a custom document process program designed by the author using the R statistical environment for statistical analysis and data graphics, and LATEX for typesetting detailed and summary reports for each condition and each run. This paper looks at roll angles only, and mainly for the most extreme 34 of the 137 conditions used in the simulation matrix (six conditions in lower sea states were also included). In Part I the effects of varying BG, inertia, depth and speed, wind, wave height, wave direction, phase, and sail configuration are analyzed in condition to condition comparisons. Part II proposes new transitional stability criteria based on traditional static stability calculations and also on dynamic roll probabilities based on the results of Part I. The static criteria is based on a minimum GM of 0.15 feet, minimum levels and times for stability restitution, and energy comparison. The dynamic criteria is based on the probabilities of exceeding 30, 45, and 60roll angles in beam seas corresponding to sea states 6, 7, and 8.},

abstract = {Modern ship design practices require knowledge of a vessel s mass Moment of Inertia (MOI) for various aspects of performance analysis. To find an accurate MOI value of an object, one needs to know the object s actual shape and density to be able to calculate the MOI through integration. Determining the exact MOI for a complete vessel, comprised of thousands of items, is not practical. Instead, engineers simplify the parts of the vessel to point objects or to standard shapes like a box or a cylinder, and calculate an approximation of the MOI. The accuracy of this approximation is dependent on the number of parts the vessel is divided into and how well the shape, orientation and density of each of the simplified items resembles the real objects. The quantification of the inaccuracy involved is seldom addressed. This paper describes a method to find the absolute error range for this simplified MOI calculation by finding the extreme values the MOI approximation can generate, and quantifies the effect that an error in MOI can have on the results of various types of performance analysis.},
