UBeSafe! vs Bollard Pull Calculator

The UBeSafe helps enquire the safety of the staff of their organization and helps staffs to respond of their where about by various channels (SMS, email, and Mobile Application based notification) in the event of a natural disaster or emergency. 1. There are various disaster feeds available from government/ public companies (google, etc.) also certain IoT devices installed in-house can tell us about the disaster. These can be captured and admin can be notified to be send to its organisation employees (the availability and feasibility of this feature needs to be explored). 2. Once the message to be send is ready, on an account of a disaster, admin can send the notification via SMS, email or App to all the staff. 3. Admin will have option while creating group to select particular employee per their organisation/office to which they belong to. This will facilitate in sending notifications for region specific disasters. 4. Notification sent by Admin to any subscriptions group will be received by all the employees registered against that subscriptions group. 5. Employees will have option to reply to the notification via app OR email OR SMS. They can reply via all channels too, individual response by individual staff through multiple channels will also be treated as one response, and the latest response received against an individual across channels SMS/App/Email will be considered (as earlier response on received on the same event will be overridden) as her/his latest response. However their message details will be saved and displayed to admin to let her/him know about employees where about. 6. Intelligent Dashboard giving one shot view to the admin and staff (restricted view) of particular event with number of responses received, not received to be shown.

The Bollard Pull Calculator is a handy tool for the maritime industry, providing precise calculations for towing forces. It is essential for ship design, port navigation, and towing operations. With its sophisticated algorithms and parameters, the calculator accurately determines bollard pull force, enabling maritime professionals to ensure safety and efficiency in vessel operations. Elevate your maritime ventures with the Bollard Pull Calculator's comprehensive features and capabilities A handy and simple tool to determine in a minimum time what is really needed as tug assistance, is the "Bollard Pull Calculator" which calculates in an approximate way the total required tug power for ships in various conditions of wind and current. This tool can be loaded as an app on the smart phone. The tool is based on the calculations and graphs as explained in chapter 5 of  the book “Tug Use In Port”, written by Captain Henk  Hensen FNI; The Nautical Institute, London, UK, with a 3rd edition published by The ABR Company, UK ( 2018). Moreover, formulas of linear and non-linear regressions obtained from academic and scientific studies have been digitalized and made suitable for mobile application.

(2003), Parameter identification of wind loads on ships, Werner BLENDERMANN [1993]) Assumptions Values & Coefficients for wind Calculations * Density of air in kg/m³ is assumed as 1,28 * The wind drag coefficients assumed the trim is zero in the fully loaded condition and 0.8 degrees in the ballast condition. * Wind drag coefficients (nonlinear diagrams) of VLCC (laden or in ballast)/Prismatic & Sypherical Gas Carrieers in determined by wind tunnel tests are taken from OCIMF MEG4. (The wind coefficients are based on data obtained from wind tunnel tests  conducted at the University of Michigan in the 1960s.) The wind coefficient values are based on a comprehensive set of wind tunnel tests conducted on prismatic and spherical gas  carriers for SIGTTO's Prediction of Wind Loads on Large Liquefied Gas Carriers (2007). Model tests covered the following sizes: Spherical 125,000, 135,000 and 150,000m³ / Prismatic 75,000,135,000 to 155,000, 210,000 and 260,000m³ * Wind drag coefficients (nonlinear diagrams) of "General cargo/Container" in determined by wind tunnel tests (Post-Panamax Full loaded cond.)are taken from Andersen I.M.V. 2003 * Wind drag coefficients (nonlinear diagrams) of "PCC/CRUISE LINER" are taken from W.Blendermann,1994/2014 * Wind drag coefficients (nonlinear diagrams) of "DRILL SHIP", "FISHING/CUTTER", "DIVER/RESEARCH/OFFSHORE SUPPLY VESSEL" Assumptions Values & Coefficients for Current Calculations * Density of sea water in kg/m³ is assumed as 1025 * The trim is assumed to be zero for all the current drag data and the effects of trim on current coefficients were not investigated. (However, the effect of trim will be most pronounced for the yaw current coefficients for ballasted tankers in shallow water.) * Current drag coefficients (nonlinear diagrams) of VLCC (laden or in ballast)/Prismatic & Sypherical Gas Carrieers are taken from OCIMF MEG4.The current coefficients are the result of Computational Fluid Dynamics (CFD) modelling, performed by Lloyd's Register on behalf of OCIMF, and have been extracted from a 2017 report  on that work. (Full scale CFD modelling run on ships of 50,000,150,000 and 300,000 DWT.) IMPORTANT NOTE: Please note that data provided by the application are based on theoretical calculations. The calculations give an indication of the required bollard pull and should always be handled with care. This tool has been developed for informational use only and cannot be used as a direct reference when performing ship manoeuvres.
