Doha Marine Services believes it has a solution to the squeeze on rates in the offshore support vessel market.

The company, part of DP World-controlled shipowner P&O Maritime Logistics, wants oil and gas clients to pay only for the vessel capacity they need.

The "pay as you go" model offers customers the chance to book space on ships that operate on fixed rotations in the Middle East Gulf, rather like a liner service.

This tears up the traditional model of oil companies chartering ships for spot runs to rigs.
