Using VesselsValue's Offshore mapping service VV@, Senior Offshore Analyst Charlie Hockless has put together a snap shot showing the percentage of the offshore fleet currently laid up. Across all offshore types, 28% of the fleet is currently laid up, with PSVs topping the table with 36% of their fleet currently laid up.

Mr. Hockless explains the definition of 'laid up' used in this context: 'Estimating the number of vessels in lay-up is an imperfect science, however, using a big data approach VesselsValue can provide a valid estimation using the following methodology. VV observes the recency of a vessel's AIS signal and filters the data appropriately. Vessels that have not signaled for over a week are considered to be in lay-up.'

The VesselsValue offshore database includes:

• Offshore Support Vessels (PSV, AHTS, AHT, FSV, Ocean Going Tug and ERRVs)
• Offshore Construction Vessels (Pipe layer, Cable Layer, Well Intervention, Dive Support Vessels, MPSV, Floatel, Accommodation Ship, Crane, Lift Boats, SOV, Utility Vessel)
• Mobile Offshore Drilling Units (Drillship, Semi submersible, Jack Ups)
