Indonesia's Wintermar has fixed out two platform supply vessels (PSVs) for seven years each.
The company said the unnamed ships will take cargo out to rigs for a major oil and gas company in eastern Indonesia.
Sugiman Layanto, Wintermar's managing director, said the project requires dynamic positioning 2 (DP2) operations while the vessels are approaching the platform.
"With our long experience in offshore deep water drilling campaigns since 2011, we are confident to be able to meet the high standards required for this campaign," he added.
