Why would an oil company want to know how much fuel your supply vessel burned last month? For years, few charterers asked. Today, many of the companies that charter OSVs report their own emissions against shared frameworks, with independent checks. The Oil and Gas...

A PSV delivered in 2008 was a scrapping candidate in 2017. In 2026, the same vessel is on a term charter in West Africa, earning rates its owner had not seen in a decade, and being asked by that charterer to report fuel consumption per operational mode with the same...

A charterer disputes an invoice. The shipowner pulls three different reports, and none of them agree on how many passengers the vessel was occupied. That gap is where most of the cost control problems start. It's rarely bad faith on either side…But each error can be...

Offshore Supply Vessels (OSVs) can burn from 1 to 8 m³ of fuel per day - yet most operators still rely on a single aggregated number to track it. This blind spot hides inefficiencies, distorts CO₂ reporting, and limits operational decisions. Structured fuel...

Offshore fleet management runs on operational data collected across multiple sources simultaneously: vessel logs, AIS feeds, onboard sensors, and engine management systems. However, consolidating these sources into a single reliable picture requires structure,...

The Offshore Support Journal Conference returned to London in February 2026, bringing together shipowners, charterers, class societies, and technology providers to discuss the current state of the OSV market and its outlook. Opsealog was present at the event, with...

Fuel optimization is often treated as an isolated objective. In reality, its success depends on one critical factor: data quality. Without accurate, consistent data, identifying trends or deviations becomes guesswork, which is something few teams can afford. Yet fuel...

The success of any digital initiative at sea or in maritime operations doesn’t depend on the technology — it depends on the people using it. Crews already balance tight schedules, heavy reporting, and demanding operational requirements. A new dashboard or reporting...

Engine running hours are often treated as a background metric. Yet for offshore vessels, they carry direct operational and financial consequences. Maintenance frequency, fuel use, emissions, and even asset integrity all connect back to how long engines are in use, and...

Offshore charter party agreements are contracts that govern day-to-day operations, define fuel responsibilities, and can quietly drain budgets and relationships if not managed well. Yet, despite their strategic importance, many offshore charter track contracts are in...
