The Time Charter In is a contract for a vessel from the perspective of the Charterer; you are acquiring a vessel for your use. Hire is paid in advance, and the Billing Period is usually 15 days. The first payment includes the Time Charter hire for the applicable period, plus Gratuities and bunkers. Typically, you buy the entire amount of bunkers upon Delivery of the vessel. When the vessel is Redelivered, the owner buys back the entire amount, at the price stated on the contract.

The Time Charter In form provides a system for managing the information and payments for vessels chartered in from other parties. A Time Charter In contract for a vessel with ownership type OV is a Head Fixture.

Creating a Time Charter In

  • To create a Time Charter In, do one of the following:

    • On the IMOS7 menu, hover over New and then click Time Charter In.

    • In the Trading

      , Chartering
      , or Operations
       module center, click Time Charter In.

    • On the TC In List, click

       and then click New TC In.

    • To copy a Time Charter In, click

      , then click Copy to TCI. You can also create a Time Charter Out by clicking Copy to TCO.

  • In the Time Charter form, enter the contract details, including: Vessel, Counterparty, TC Date, Delivery/Redelivery ports and estimated dates, Hire Information, and Bunkers quantities and prices.

  • When you save the form, IMOS generates a Time Charter Code. You can now select this Time Charter Code when you are creating a voyage; the Time Charter information governs the voyage, and the voyage becomes part of this Time Charter.

When the First Voyage is Scheduled

  • The Actual/Projected Delivery date and time automatically appear in light blue font, to indicate that those values are projected.

  • If the Delivery Port in the Voyage Manager (first port in the itinerary) is different than the Delivery Port set in the Time Charter In, the port gets updated in the Time Charter In.

  • On the Bunkers Delivery/Redelivery tab, the Actual/Projected Delivery quantities and prices are automatically set for each Fuel Type.

When the First Voyage is Commenced - Vessel is Delivered

When the first voyage is commenced, the Delivery information on the Time Charter In is updated to match the information on the voyage, this time as Actual and not Projected: The Delivery Port, Delivery Date/Time, and the bunker quantities are updated according to the operational information from the voyage. The Time Charter In Status is automatically set to Delivered.

When the Last Voyage is Scheduled

To indicate that a vessel is about to be redelivered upon completion of a particular Voyage, select the Last TCI Voy check box in the Voyage Manager. When selected, the Redelivery information in the Voyage Manager updates the Time Charter In:

  • The Actual/Projected Redelivery date and time automatically appear in light blue font, to indicate that those values are projected.

  • If the Redelivery Port in the Voyage Manager (last port in the itinerary of the Last TCI Voy) is different than the Redelivery Port set in the Time Charter In, the port on the Time Charter In gets updated.

  • On the Bunkers Delivery/Redelivery tab, the Actual/Projected  Redelivery quantities and prices are automatically set for each Fuel Type.

  • A TCI Bunkers Adj on Redelivery item appears in the Voyage P&L, in case there is an adjustment.

When the Last Voyage is Completed - Vessel is Redelivered

When the last voyage (marked as Last TCI Voy) is completed, the Redelivery information in the Voyage Manager updates the Time Charter In, this time as Actual and not Projected: The Redelivery Port, Redelivery Date/Time, and the bunker quantities are updated according to the operational information from the voyage. The Time Charter In Status is automatically set to Redelivered.


Contract Information

Add information about the vessel and the contract.

  • E/L Redel: The calculated value for Earliest/Latest Redelivery appears black. To lock it, either edit it or right-click it and then click Lock Date. When the date is locked, it appears red to indicate that it will not be recalculated upon changing one of the parameters (Delivery Date, Min Duration / Max Duration, or −Days / +Days).

When an Alert is entered for an Owner (for TC In) or Charterer (for TC Out), the field is highlighted in light red.

Summary Tree

The Summary tree is at the right; it summarizes and provides access to important forms and related information. You can attach and access documents or links.

Tasks & Alerts or Revisions Panel

Either the Tasks & Alerts or Revisions panel appears at the top right corner of the form. To expand 

 or collapse 
 it, click the double arrow.

To select what you want to view, click 

 and then click one of the following:

  • Show Tasks & Alerts: View the Tasks & Alerts panel, which displays the Tasks and Alerts that apply to the contract. The heading bar includes the icon for the most urgent Alert or Task. If none are urgent, the Task that is in progress appears.

  • Show Revisions: View the Revisions panel, which displays a chronological list of changes to the form. You can also click Revision History to view the same information in a list.

Delivery and Redelivery Grid

Add the Delivery and Redelivery ports and times.

  • Use Local Time: Select to show delivery and redelivery dates in local time instead of GMT in contracts, invoices, Hire Statements, and Profit Sharing forms.

    • In the first voyage for a TCI/TCO contract, Hire in the P&L considers Commencing time in local time but Ending time in GMT, unless the voyage is marked as Last TCI Voy/Last TCO Voy.

    • When there are multiple voyages under a TCI, and the last one is marked as Last TCI Voyage, the Commence time for the first voyage and the Ending time for the last voyage are considered in local time, and the rest are considered in GMT for P&L calculations.

    • The checkbox can only be changed when there’s no periodical hire invoice created.

  • Duration Basis: The Proj/Act GMT Duration (days) and the Redelivery Difference (in hours between estimated and actual redelivery time) will automatically update when the Basis is set to Min, Min excl Option, Mid, Max, or Custom (based on the Duration entered). If set to Option, then these fields will not automatically update. Configuration flag CFGSetDefaultTCDurationBasis enables you to set the default Duration Basis.

Pricing Tab

On the Pricing tab, you can add Hire information, Broker information, and Common Voyage Expenses.

Hire Grid

Add Hire information: How much to pay for a TC In or charge for a TC Out.

You can set multiple rates on separate lines for different time periods, for example, if you have an escalation clause. This information is used to create the Hire Statement.

  • From GMT and To GMT are needed to calculate the period the vessel is on hire. Actual redelivery information is retrieved from the Voyage Manager.

    • Default for To GMT: If a Max Duration has been specified, the E/L Redel value from the Max Duration row is used; if Max Duration is zero, the Redelivery date is used.

  • For the Rate Type, you can select Index to assign the Hire Rate according to the Market Rate on the Index Option form.

Brokers Grid

Add information about Brokers and Broker Commissions.

  • The Type defaults to % when the rate is 25 or less, or to Daily when the rate is greater than 25.

  • If Time Charter Broker Rules are defined (when config flag CFGEnableBrokerRules is enabled), to add default brokers, click 

     and then click Add Default Brokers.

  • For Broker Commissions (not XADDCOM), when the Payment Method is "Deduct from hire“, a TC Commission invoice needs to be created and posted in order for this entry to appear in the P&L of the relevant voyage. This is in addition to including the commission in the hire invoice (TCI Payment).

Note: If an invoice spans a change in the Hire Rate, Broker Rate, or both, the amounts due calculate correctly.

Common Voyage Expenses Grid

On the Common Voyage Expenses grid, you can set up additional cost items payable by the Charterer to the Owner, including both one-time and recurring costs. Carrying out this setup causes the applicable items to appear automatically during the Time Charter invoicing process, where you can choose whether they actually apply and should be added to the particular invoice. You can specify a period-based rate for items that do not have a Rate Type of Lumpsum.

Bunkers Tab

On the Bunkers tab, you can enter itemized Bunker information, which flows into the FIFO queue.

These tabs are parallel, but from the other perspective, for a TC In and a TC Out:

  • Whenever changes are saved to the initial bunkers in the first voyage in the TC, the changes update this tab as well. If the voyage has not yet been Commenced, the figures are considered Estimated; after the voyage has been Commenced, the changes are considered Actual.

  • IMOS locks old records and manually edited quantities and highlights those lines in pink:

    Those records are not synced between the voyage and the Time Charter.

    • To enable an old record to use these new functions, save the Voyage Manager.

    • To unlock a record, right-click the line and then click Unlock.

  • To see or edit information about bunker quantities and prices on delivery and redelivery, click

     on the bottom of the tab to open the Delivery/Redelivery Bunker Breakdown form.

Exposure Tab

On the Exposure tab, you can enter the Exposure information as it will be processed in the Trading module.

The Time Charter Route and Correlation used for the Mark-to-Market of the Time Charter is taken from the Vessel Type if details in the Exposure tab are not completed. Otherwise, if you select a Route in the Exposure tab, this Route will be used for the Mark-to-Market.

  • Using the TC Exposure Periods table, you can mark your positions to market based on multiple routes for different periods.

  • Using the Bunker Exposure table, you can track hedging your bunkers for delivery and redelivery against a forward curve: Enter the bunker symbols to be used for the Mark-to-Market of the delivery and redelivery bunkers.

  • Using the Unavailable Days table, you can specify the number of days that the vessel is planned to be unavailable. This value is reflected as Weighted Days in the Trading P&L Summary and Trade Details List.

  • When a Ballast Bonus is specified on the Common Voyage Expenses grid, the Ballast Bonus Exposure information appears.

Performance Tab

On the Performance tab, you can enter speed and consumption information from the vessel owner to verify the vessel's performance.

  • Speed Consumption table:

    • Figures are separated into Ballast and Laden.

    • When the Vessel Type has Restrict Speeds enabled, the speeds available are only those corresponding to the specific B/L mode, as defined on the Vessel form.

  • In Port Consumption table

  • The Beaufort, Sea State, and Swell Force fields indicate the maximum weather conditions for which the charter party warranties are applicable.

  • Fuel consumption in conditions exceeding these maximums is tracked separately from fuel consumption under normal conditions, as follows:

    • In the Veslink Noon Report, when the Track Fuel Consumption over Weather Thresholdcheck box is selected on the System Configuration page, the Over Weather Threshold field appears in the ROB control. The shipboard user enters the amount of the daily fuel consumption that occurred in conditions over the weather threshold. This value is:

      • Sent to IMOS and stored in the Bad Weather Consumption field on the Extra Information for Report form.

      • Taken into account by all performance-related reports in IMOS. That is, this amount of fuel consumption is backed out before carrying out performance calculations.

  • Note that in case of a TCTO voyage, the TC In and TC Out contracts may have differing stipulations on the Performance tab. So, for a TCTO voyage, you can produce the Voyage Performance Report either for the TCI Fixture or the TCO Fixture.

For LNG Vessels

  • entReliqGCU/Steam, and Meter Adj consumption table columns replace Heat, Heat+, and Heat++.

  • You can include Bunker Curve Parameters in the calculation of fuel consumption.

Warranty Tab

When Vessel Type Code is L (LNG Carrier) and Vessel Type Fuel Warranty Table is other than None, a Warranty tab appears. On this tab, you can record parameters related to vessel performance warranties.

Depending on the Vessel Type Fuel Warranty Table, different fields appear.

  • FOE by Fuel Cons Mode:

  • By Plant (ME/DG/Reliq):

  • FOE + Pilot Fuel:

Notice Tab

On the Notice tab, you can track Delivery and Redelivery Notices.

This tab enables you to establish a series of points in time, measured in the number of days prior to delivery or redelivery, at which your company is contractually required to provide notification of its intention to take delivery of/redeliver the vessel. You can also record whether each required notice has actually been sent.

Such notification emails are not automatically sent; this must be done manually. Nor are any alerts generated regarding the need to send such notification emails. This is simply a place where, upon fixing the TC Contract, you can set up the contractually mandated reminders, and then, as each one is sent, track that it has been sent by selecting the corresponding check box.

  • To record notices, do one of the following:

    • Manually enter Notices.

    • In the Delivery or Redelivery field at the top, enter the number of prior days, for example, 20/10/5/3/2/1. Notices will be created based upon the estimated delivery/redelivery time, one line for each number.

  • To record that you have sent a notice, select its S check box.

  • You can set Notice dates for notices that have not been sent (S check box not selected) to update automatically as they change in a contract or a linked voyage. In the Sync All Notice Dates With field, select one of the following:

    • Do not sync (default for existing contracts)

    • Est Dates (default for new contracts)

    • Proj/Act Dates

Off Hire Tab

On the Off Hire tab, you can view a summary of all the off hire for the Time Charter contract, aggregated across the voyages.

For a delay to appear on a linked Time Charter contract, the TCI%/TCO% field on the Delay form must be populated with a number other than 0.00.

Bareboat Tab

On the Bareboat tab (only on the Time Charter In Manager), you can create and maintain additional related contracts, such as with a crew manager, that might be needed in case of a bareboat charter. (The bareboat-in charter is treated as the main contract.)

Properties Tab

On the Properties tab, when User-Defined Fields are set up in the Data Center, they can be selected here and values entered for them.

Invoice Items Tab

INTHC items can be billed multiple times in the course of a Time Charter Contract; on the Invoice Items tab, all the INTHC/INTHC rebill items that were invoiced in the contract appear.

Linked Trades Tab

On the Linked Trades tab, you can link FFAs so that you can keep track of hedging related to each contract, or Bunker Swap lots (per month) by selecting from those that are not linked to any other contract. To view the linked contract, right-click the line and click See Trade Details/See Bunker Swap. If there was no value in the Reference column, the Contract ID is populated in this field.

Linking FFAs to a Time Charter In does not impact the Trading P&L, Trade Details List, or Voyage P&L.

Lease Tab

NoteConfiguration flag CFGEnableTCLeaseAccounting must be enabled.

On the TC Lease tab, you can set up lease accounting for the contract:

  1. To enable Lease Accounting, select the check box. It is selected by default for saved contracts greater than 365 days and either fully or partially past the lease transition date (the value of configuration flag CFGTCDefaultLeaseTransitionDate).

  2. To create a Lease Service Schedule, for each Period From/To, add a row to the grid that includes an Interest Rate %, Service Fee, and Rate Type.

  3. If the lease is modified, you can update the Hire Rate, Duration, Duration/Basis (Days), Address Commission, Service Fee, or discount rate to reflect the changes.

Lease Value History displays Time Charter Period Journals that have been created for the contract.

For more information about the lease accounting workflow and IFRS 16, see Compliance with IFRS 15 and 16 Regulations.

Remarks/Notes to Operations/Roles

At the bottom of the Time Charter form, you can enter general, free-text Remarks to print on the Time Charter report, enter Notes to Operations to appear on the Voyage Manager, and (if configuration flag CFGEnableVoyageRoles is enabled) assign Controller and Finance Coordinator Roles for the Time Charter.

You can also enter Notes to Operations within the Fixture of the voyage under Remarks.

For Time Charter In contracts, you can also enter Owner's Commissions information.

TC In List

All Time Charter In contracts appear on the TC In List. In the Trading 

, Chartering 
, or Operations 
 module center, next to Time Charter In, click List.

The TC In List is a standard IMOS list, so you can sort it, filter it, do a Quick Search, and create custom Views for it.
