Bollard Pull Calculator vs Pilot Eticket

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. (BS 6349-1, OCIMF  Mooring Equipment Guidelines (MEG4) 4th Edition 2018, SIGTO’s Prediction of Wind Loads on Large Liquefied Gas Carriers (2007), Post-Panamax Full Loaded Cond. Jare, Andersen I.M.V. (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.

HPFS Eticket is paperless version of Pilot Ticket, signed by the Master of the Vessel, agreeing to the terms and conditions of the services being provided and is attached to the invoice when billed. The Eticket significantly increases the accuracy of the billing process in addition to creating efficiencies in the billing cycle. When utilizing the Eticket application a pilot can view, in real time, on their phone, the total jobs and revenues completed for the day, week or month. Eticket processing can increase accuracy and efficiencies through use of drop-down menus, a ship data base, and removal of the manual process of handwriting tickets, sending them snail mail, then scanning the ticket to attach for invoicing. Working with Harbor Pilots for almost three decades and seeing significant delays in collections on invoices and inaccuracies in the billing process we saw a need to streamlines the process. When handwriting tickets, sending them snail mail to get processed, it could be over a month before you find out that one number on the ticket was incorrect. The Eticket significantly decreases, if not eliminates, rebilling for inaccuracies and the time taken to research accurate ship information. We have compiled a data base of Vessels from accumulated Ship Particulars. Over the years, we have found inaccuracies in LLYODS and other data bases. Our database is compiled from ship particulars. All organizations using the Eticket application will benefit from the addition of a vessel. As the number of users increases, the database will accumulate for the benefit of all users at no additional cost. The Eticket will be customized for your organization, knowing all Harbor Pilots use different calculations for their units and billing. Your organization’s calculated units, harbor rates and disclosures will be specific to your organization or you as an individual. The information from the electronic ticket will be accessible to you or your organization’s billing department for review, edit, download or submission. Each pilot can search and retrieve previously prepared tickets to tract to invoicing. With 30 years of billing and collection experience, we have a team that can prepare the invoices and provide billing/collection services for your organization or support your billing department for servicing. The ability of information on the Eticket to be imported into accounting software, such as Quickbooks, for invoicing,.streamlines the billing process producing efficiencies and more accurate billing. Do you work with Tug Boat companies such as Sandy Hook or Moran and are required to remit tug boat tickets? In addition to the ETicket for billing of your services we have available a Tug Boat Eticket. Transitioning the paper form of the Tug Boat Ticket to an electronic version transitions your entire process to a paperless process.
