On-Line Interface to Tank Level Gauging System

This module of ANKO provides the necessary components for interfacing to all known Tank Level Gauging Systems.

To this effect, the communication protocol provided by the tank level gauging system manufacturer for the specific vessel, is implemented.

The on-line readings automatically update the tanks' loading status (Ullage/sound, volume, Temperature), the vessel's floating position, strength and stability are calculated and when required, parameters are transmitted back to the gauging system.

The whole process is interactive. The user, at any time, has an overview of tanks' flow rates, time to reach high or load level settings as well as the vessel's status.

If a strain gauging system is installed, ANKO will read the measured stresses and display them against the calculated ones.

Bar Chart View

In the on-line mode an alternative window is provided that displays the tanks' contents and other useful information in a graphical bar chart view. High and low level alarms are user defined and clearly displayed on the bar chart view together with the actual tanks content level. Audible and visible alarms are built in with the option to mute as required.

Historical Database

Voyage History database

Provides information for tracing and evaluating vessel utilization within a period. It contains information on previous voyages such as departure/arrival, from/to ports, dates, cargoes carried as well as the actual vessel's loading.

Loading History database

Contains all previous vessel loadings with information on a per tank and cargo basis. Allows queries, related to cargoes carried by the vessel or cargoes loaded in a given tank and in a time period.

Tank Cleaning History database

Stores the cleaning procedures followed, and allows a range of queries regarding the cleaning history of tanks, including notes on the procedures followed.

Tank Condition History database

Defines and stores the “Tank Condition Report”. Provides a graphical representation of the tank bottom/sides, where the user can interactively mark the location, extent and degree of tank coating deterioration. Possibility to store and retrieve, apart from the of “Tank Condition Reports”, the corrective/maintenance activities carried out in a tank, between reports. Full validation to warn the user and prevent erroneous entries.

Tank Technical Database

This database contains specific technical information about the devices and the systems that each tank is equipped with. Such information includes:

  • Cargo Information such as min/max cargo temperature, cargo lines, drop lines
  • Monitoring Devices such as pressure monitor device, tank coating, temperature
  • Specific Information such as tank vent, tank capacity, tank surface area
  • Heat Cooling Systems such as heating coil, cooler, diffuser

AutoPlan automatically loads and distributes cargo, consumables and ballast so that:

  • Required quantities of one or more cargoes and/or maximum quantity of one grade are loaded
  • Minimal stresses are exerted on the ship structure
  • Operational constraints such as draft/trim and strength levels are met

Multi-port, step by step planning is supported. AutoPlan is a unique decision support tool for ship operation and chartering.

Graphical Stowage Plan Summary

Single page presentation form of loading summary typically used to provide stowage overview to charterer.

The form displays a colour graphical Tanks Arrangement. The information on each tank includes the grade carried, its density, quantity and POL, POD. Summary by grade and other on board weights are also included in the form. The form can be printed, customized with the company logo.

Pre-Planning - Loading Simulator

This module is designed to facilitate load Pre-Planning through an interactive simulation of the loading/unloading process. The process is time based, takes into account the load and discharge rates and monitors the various strength and hydrostatic parameters throughout.

Detailed graphs for the variation of strength and stability parameters such as trim, drafts, GM, SF, BM over the duration of the load/discharge operations are provided.

ASTM/IP Conversion Tables

This is an independent utility, which allows the conversion between a wide variety of cargo density units for Crudes and Products. In addition, it calculates the density variation for different temperatures taking into account the hydrometer correction. During loading, the above process is done automatically in the background. The following ASTM Tables are included: 5A, 5B, 6A, 6B, 6C, 23A, 23B, 24A, 24B, 24C, 53A, 53B, 54A, 54B, 54C.

Bunkering

Provides complete pre-bunkering, post-bunkering and comparative summary calculations and reports. Trim, heel and temperature corrections are applied. Averaging of densities and sulphur content per tank are accounted for.

The user inputs initial and final ullages or soundings of FO, DO, LO tanks at a specified trim and heel, at which measurements have been taken. The system corrects the input ullages for Trim and Heel, as well as for temperature variation. The calculated corrected ullages can optionally update the active loading condition of the vessel.

Both Initial and Final bunker surveys are available.

The bunkering module takes into account:

  • Density variation due to mix of different densities in tanks
  • User-defined High/Low limit for sulphur content percent
  • High & Low sulphur, percent sulphur content adjustment, due to mix of fuels in tanks
  • Consumed fuel or diesel during bunkering and other useful information

Bunkering report is produced in EXCEL© format.

Loading by Non-Corrected Ullage/Sounding

This is used to load FO, DO, LO and WB tanks based on the non corrected ullage or sounding measurements.

The system corrects input for Trim and Heel, as well as for temperature variation and the calculated quantities directly update the actual loading condition.

Draught Survey

Based on the readings at the draft marks, it calculates the loaded cargo or the vessel constants. Corrections are made for Trim, Hogging/Sagging and Sea Water Density.

Provides two modes of operation:

  • Before Loading: Calculates actual constants and OBQs and their LCG
  • After Loading: Calculates the cargo loaded

A combined Initial and Final draft survey version is also available to enable comparative display and printing of Before and After Loading draft survey results.

Air Drafts

Air drafts are calculated and displayed on any number of predefined longitudinal positions.

Air drafts are are also calculated at the side of the hatches.

Visibility Check

This module performs a visibility check, as per the SOLAS Reg. 22a.

The 2D version calculates and graphically displays the invisible length.

The 3D version carries out detailed geometrical calculations and graphically displays both the invisible length and the blind and clear visibility sectors.

Calculations take into account the actual shape of any obstacle, such as loading gear, container or other deck cargo. Furthermore, calculations are made for the loading condition that is the actual trim, heel and draft of the vessel Additionally, it checks invisible lengths for Panama and Suez canal navigation.

The view point can be on the center-line, or be moved transversely. In addition, trim heel and draft can be modified interactively so that the visibility for alternative loading conditions may be examined.

In ballast exchange operations, the visibility is checked in the background and a warning is displayed, if needed.

Deadweight Scale - Parallel Middle Body

Given the:

  • Sea water density
  • Trim
  • DWT, Displacement or mid draft

This module calculates and displays drafts at PP and marks, DWT and displacement, as well as a number of important hydrostatic parameters.

In addition, the parallel middle body (PMB) and the distance of aft/fore ends of the PMB from amidships are also calculated and displayed.

Sloshing Calculations

For the actual loading condition, every tank is checked against resonance between ship and liquid motions in tanks, both pitching and rolling, as per pertaining classification rules.

Gain/Loss of Cargo due to Sagging/Hogging

This calculates the deflection, that is, Hogging/Sagging of the vessel and estimates the respective gain/loss of cargo.

Vessel Particulars and Plans

Displays vessel particulars. Furthermore, enables addition of any number of ship-related files by the client, including ship's drawings. The added files are automatically identified by the software and added in the list of items that the end-user can select for display.

The General Arrangement, Capacity Plan and Mid-ship Section, are included as a standard in the initial software delivery.

Additional drawings can also be included, subject to agreement.

SAFESALV - Emergency Response

SAFESALV is an advanced system for the immediate assessment of Damage/Grounding vessel conditions and the evaluation of alternative salvage scenarios. SAFESALV provides all those facilities which allow the on-line interactive examination of What If scenarios, making it a powerful decision support tool.

The SAFESALV system is used for Emergency Response.

In SAFESALV the user defines the initial loading condition and indicates the damage on the vessel, working on the actual vessel plan. In case of grounding or combined damage and grounding, the measured draughts at selected points around the vessel, as well as the type, and optionally the extent, of grounding, are input.

As soon as the damage is specified, the floating position in the damaged condition is found. The IMO damage stability criteria are checked and the stresses exerted on the ship’s structure are calculated. User inputs and calculated results are graphically displayed.

Flooding

The cargo permeability can be set by the user. For partially filled holds with bulk cargo, calculation of the combined permeability is carried out. In particular, the system considers the loaded and free space of each hold with different permeabilities. Depending on the calculated in-flooded water level, the combined permeability is found and accounted for.

The damage calculation is based on either liquid surfaces parallel to the waterline or, optionally, on frozen surfaces. Damage conditions can be stored and complete reporting is available.

Marginal points are displayed graphically. In the print out the calculated actual Free-board and Immersion angle at each marginal point are shown.

Cargo Shift

Given the heel of the vessel, the shifted cargo TCG is adjusted so that the calculated heel matches the observed.

Grounding Calculations

Grounding and re-floating calculations include:

  • Grounding area
  • Grounding force and position
  • Force required to free the vessel
  • Pressure on grounded area

Different types of grounding, that is, on One Pin, Two Pins or Seabed can be examined. Tide can also be defined and taken into account.

Off-line interactive evaluation of corrective actions/scenarios can be carried out.

Simultaneous flooding and grounding is supported by SAFESALV.

Residual Strength

Provides an estimation of the effect of the structural damages on vessel's strength. The position and extent (in terms of length, breadth and depth) of the structural damages are given by the user. The residual strength is estimated by re-definition of the permissible bending and shear stresses after the structural damages.

Note: SAFESALV is also available as a Stand-Alone Tool.

Statutory Damage Check

Performs Damage Stability Calculations on the current loading condition, as per MARPOL, Annex I, Reg.28 requirements.

The vessel is checked by default for a number of built in damage cases as specified for the vessel at hand by MARPOL. A complete summary report is produced at the end of calculation for the examined damage cases.

If not restricted by Class additional damage cases can be interactively defined.

Intermediate Stages of Flooding

The final condition of equilibrium after damage is not always the most critical. It is therefore necessary to check and verify that the stability of the vessel is adequate during the Intermediate Stages of flooding - MARPOL Reg. 28.

This module calculates and displays the vessel's status that is strength, floating position and stability criteria for a range of Intermediate Stages of Flooding. The added weight method is applied in the calculations, whereas the final condition of equilibrium after damage is evaluated by the lost buoyancy method.

The amount of water per stage is based on applicable class directives. The Lloyds Register methodology for evaluating the added water per stage is applied by default.

Damage Simulation

This is an enhancement to the SAFESALV Damage Stability/Emergency Response module. The objective is to simulate in a quasi static manner the vessel's status starting from the intact condition and follow through to the final position of equilibrium after damage.

The system by taking into account the actual position of damage openings wrt the sea level, it will:

  • Flood progressively all damaged compartments
  • Calculate and display in a tabular and graphical form the vessels status at any stage of flooding
  • Estimate the outflow, taking into account the internal gas pressure and the effect of swell
