Oil and Gas Logistics Software for Marine Contractors

You run platform supply vessels, anchor handlers, and dive support vessels for oil and gas operators. Each charter generates port calls, vendor invoices, crew changes, and billing records that need to reconcile before month-end. Base connects your fleet dispatch and your project financials so your shore team closes books without chasing spreadsheets across charterers.

What Happens When You Run a PSV Fleet on Spreadsheets

Your dispatch team tracks vessel assignments in one file. Your port agent tracks charges in another. Your finance team reconciles both against the charterer contract in a third. When the charterer asks why fuel costs ran higher last month, someone rebuilds the breakdown from scratch. The answer arrives three days late and nobody is confident it is complete.

What Is Oil and Gas Logistics Software?

Oil and gas logistics software manages the financial and operational complexity of running vessels for offshore oil and gas operations. Personnel scheduling tools handle crew manifests and helicopter bookings. Base handles what happens after the vessel is dispatched: the charges, the vendor invoices, the charterer billing, and the accounting sync. It is the financial layer between your fleet operations and your books.

How a Platform Supply Job Flows Through Base

1

Dispatch the vessel to the charterer

Assign a PSV, AHTS, or DSV to a charter. Each dispatch creates a job that tracks the vessel, the charterer, the port calls, and every charge the job generates.

2

Track charges as the vessel operates

Day rates, fuel, port fees, crew overtime, provisions. Every charge maps to the vessel, the job, and the charterer. Your offshore operations team and your finance team see the same running total.

3

Process vendor invoices against jobs

AP automation captures vendor invoices, matches line items to the job, and routes for approval. Port agent fees, bunker invoices, and service charges all tie back to the vessel.

4

Invoice the charterer from approved charges

Generate the monthly invoice from charges your team already approved. The charterer sees the same cost breakdown through Base Connect. No more rebuilding spreadsheets on the 5th.

5

Sync to your accounting system with full job context

Every approved charge flows to Xero or QuickBooks with vessel, charterer, and job references. Month-end close becomes a review, not a reconciliation.

Three Reasons O&G Contractors Hesitate

"We already use DaWinci or Kabal for personnel logistics."

Those tools schedule crew transfers and cargo manifests. Base handles the financial layer: charges, invoices, payments, and accounting sync. Your logistics tool plans the voyage. Base tracks what it costs and bills the charterer.

"Our fleet serves multiple charterers across different regions."

Each charter is a separate job. Filter by charterer, by vessel, or by region. Multi-currency support means port fees and charterer billing operate in their own currencies. Reporting consolidates to your base currency.

"We need per-vessel profitability across all charterers."

Every charge carries the vessel and charterer reference. See margin per vessel across all its charters, or drill into a single charterer. Fleet management and financial data share the same records.

Oil & Gas Operations

See Your Fleet and Your Financials Connected

Walk through a platform supply job from dispatch to invoice. See how port call charges, vendor costs, and crew expenses roll up per vessel, per charterer, and per job. Bring your fleet list and your charterer rate cards.

“Our shore team and our billing team used to work in completely separate systems. Now they share the same job record. When ops closes a port call, finance already has the charges ready to invoice.”

Stop Rebuilding Charterer Invoices from Spreadsheets

OSV operators that run their fleet financials in Base typically close their books five days faster within the first quarter because dispatch, billing, and accounting share the same vessel and job data.
