Company at a glance


2020 marks the 50th Anniversary of the Wintermar Group. From humble beginnings as a tug and barge operator, the Company has transformed into a strong regional player in the Offshore Support Vessel Industry. Starting in 1970 with a small fleet of wooden tugboats, the Company today is the industry leader in Indonesia and operates in over 12 countries, with Offshore Vessels equipped with the latest Dynamic Positioning 2 (DP2) technology. In our fifty-year journey of building strength in all aspects of our business, Wintermar has gained an excellent track record and a long list of highly discerning multinational clients.

Our Vision of becoming the Leading Operator of Marine Vessels in the energy industry in South East Asia has been gradually unfolding. Wintermar is strongly committed to developing our People, Fleet and Services to build a highly efficient and competent business.


Our dedicated and experienced offshore personnel work tirelessly to deliver customized solutions and support across the exploration, development, construction and production phases of the oil and gas cycle. Our high commitment to health, safety, environmental and quality (HSEQ) issues is supported by verified external audits, client audits, external awards and certifications. Training of onshore personnel and vessel crew is highly prioritized, as we build up the competencies of our people.

Understanding our clients’ needs, the management has evolved and developed a strong internal process and a corporate culture of working with Integrity in every aspect to deliver a high value-added service, while staying on top of industry trends to match the evolving technology and tightening regulations in the industry. Our internal management system is certified by Lloyds Register Quality Assurance (LRQA) with ISO 9001:2015 for Quality, ISO 14001:2015 for Environmental Management and OHSAS 18001:2007 for Occupational Health and Safety standards.


Wintermar’s close attention to vessel and crew quality, together with a strong balance sheet, has enabled the company to stand resilient through very difficult times and kept us at the forefront of the industry despite the challenges of the oil and gas cycle.


With a young and sophisticated fleet, deep industry expertise and a strong commitment to high standards of safety and quality, Wintermar has a wide geographical client base in South East Asia and has in recent years ventured further into Africa, Russia, the Middle East and South America. Advanced IT systems allow fleet movements to be tracked by satellites and monitored in real time by onshore vessel teams, while vessel inventory and maintenance are controlled by specialized ship management software.


In an industry where clients demand high standards of safety, environmental protection and quality, Wintermar’s strong reputation for professionalism and integrity, built over many years of hard work, has established the Company a trusted provider of offshore support services. Wintermar’s base in Indonesia, the largest oil producing country in South East Asia, enables the Company to command a strong geographical advantage to access the regional markets, and the Company has already made inroads into Brunei, Malaysia, Thailand, Myanmar and Papua New Guinea. Wintermar has also widened the scope of services provided to include the support of underwater inspection, diving and ROV operations, seismic surveys, cable laying, oil spill containment and pipe-tailing.
