Winston Score History

The full picture

PT Wintermar Offshore Marine Tbk is an Indonesian company that provides ships and marine support services to the oil and gas industry. It owns and operates a fleet of offshore support vessels — including anchor handling tugs, platform supply vessels, and crew boats — that help oil companies move equipment, supplies, and workers to and from offshore drilling platforms. The company mainly serves energy companies operating in Indonesian and Southeast Asian waters.

Wintermar earns money by chartering out its vessels under contracts, meaning customers pay a daily or monthly rate to use the ships. The company is based in Jakarta and operates primarily across Indonesian waters, with some regional exposure in Southeast Asia. Its competitive position comes from its established local presence, relationships with major oil and gas operators, and its Indonesian-flagged fleet, which benefits from cabotage rules that limit foreign vessel competition. The main risk is that demand for its services closely follows oil and gas exploration activity, making revenue vulnerable to swings in energy prices.
