Wintermar's Commitment to Excellence in Environmental Management, Paving the Way for a Sustainable Future


Even though Wintermar does not have operations near or in a conservation area, the Company is aware that our operations in the oceans have an impact on biodiversity, which can disrupt species and can cause pollution both under the sea and in the air. The Company seeks to reduce damage to underwater ecosystems and preserve the rich biodiversity of marine life through the following actions:

  • Using TBT-Free Anti-fouling system paint, which is an organotin-free Tributyltin-free anti-fouling paint to control or prevent the attachment of unwanted organisms according to the provisions of the IMO International Convention
  • Using shore power connections at ports to reduce emissions produced by generators on board
  • Achieved the target of “zero oil spill” in 2020, 2021 and 2022
  • Wintermar's fleet is certified with IOPP (International Certificate of Prevention of Pollution by Oil), International Certificate of Prevention of Pollution by Air (IAPP), International Certificate of Prevention of Pollution by Pollution (ISPP) in accordance to MARPOL regulations
  • Each vessel in the  fleet has a Garbage Management Plan, Ship Energy Efficiency Management Plan and Shipboard Oil Pollution Emergency Plan in accordance with MARPOL provisions for the prevention of pollution through proper management of waste, emissions and oil in the sea and air.
  • Conducting a SAY NO TO SINGLE USE PLASTIC campaign for on shore and on ships
  • Replacing the ballast system on Wintermar's fleet according to the Ballast Water Management Convention. All vessels have to avoid discharging ballast water to prevent the introduction of unwanted aquatic organisms.

Zero Oil Spill

Wintermar continues to achieve the target of ZERO SPILLS in the Company’s operational business.

          Managing Emissions Through Energy Efficiency

          Energy Use and Efficiency

          The Company uses energy from fuel and electricity in its operations, which impacts the environment through emissions. Through our Sustainability Policy and Strategy we are committed to reducing the impact of our ship operations and business activities on the environment through mitigation of natural resources depletion and pollution. The Company uses electrical energy by purchasing electricity for vessels at ports and increasing the use of B30 fuel oil.

          We also continue to strive to reduce air emissions through energy efficiency and various policies, initiatives and sustainable innovations that contribute to reducing GHG emissions. Some actions taken to reduce energy consumption are as follows: 

          1. Use of Biodiesel: The Company has been using Biodiesel since 2019 in all vessels operating in Indonesia. In 2022, the biodiesel used was B30 with 30% biofuel content, an increase from 2019 where the biofuel content was 20%.
          2. Shore Power Connection for Vessels at Berth: By arranging for vessels to be connected to electricity on shore, the Company reduced the consumption of diesel for Auxiliary engines in the production of electricity for vessels berthing, resulting in fuel savings of 100% of the fuel which would otherwise have been consumed to operate the auxiliary engines.

          Efforts to Reduce Emissions

          Wintermar seeks to reduce GHG emissions by maximising operational efficiency and using renewable energy and digitalisation, such as biofuels or biodiesel in form of support to the Government for the sustainable use of biofuels, using shore power connection, and digitalisation.

          Use of Biofuel

          By substituting biodiesel for high speed diesel, the Company was able to reduce emission CO2. In addition to biofuels, the Company also uses High speed diesel, and both of these fuels have a sulphur content below 0.50% m/m in compliance with the mandate from the International Maritime Organization (IMO).

          Digitalisation of Processes to Reduce Paper Usage

          As part of our commitment to reduce paper usage, in 2022 the Company increased its adoption of new digital applications to replace the previous approval process that was paper-intensive. The digitisation process in our business operations has succeeded in decreasing paper use significantly.

          Shore Power Connection at Ports to Reduce Fuel Usage for Ship Generators

          The use of Shore Power connection for vessels which were berthing was another action taken to reduce emissions. This resulted in savings of 100% in CO2 emissions which would otherwise have been generated if the vessels had used diesel to generate electricity on board. In reducing emissions at ports, we use electric shore connections at 6 ports across Indonesia.

          Control of Ozone Layer Depleting Emissions

          Wintermar uses refrigerant R-404 A, R410A with an Ozone Depletion Potential (ODP) index value = 0. In addition, our fleet also maintains a refill system containing ozone depleting substances from leaks by keeping regular records when refilling and carrying out equipment maintenance in the Ozone Depleting Substances Record Book in accordance with MARPOL Annex VI provisions.

          Waste Management

          The operation of vessels produces various types of waste from our head office as well as waste on board the fleet where crew members live and work. Wintermar only measures waste generated by the Company’s own operations and mitigates these negative impacts through responsible management of waste  in compliance with applicable regulations, such as ISO 14001:2015 Waste Environmental Management System and MARPOL Annex V.

          Waste is managed through the application of a waste management hierarchy of Prevention, Reduction, Reuse, Recycling, Treatment, and Disposal. The use of single-use plastic is being phased out through policies to  provide  reusable containers to replace single use plastic containers, and reducing plastic packaging and minimising waste by bulk buying.

          For waste management onboard, all vessels are required to separate waste according to waste categories and place it in the temporary waste disposal sites that have been provided onboard. On arrival at the shore, these wastes are then disposed of at a certified onshore facility by a certified third party. The generated waste is then recorded daily through a digital Garbage Record Book in the Company's system. The data is monitored and analysed to ensure responsible consumption.

          Meanwhile, waste management at the head office is carried out by separating waste according to the category and placing it in the bins provided. Afterwards, the segregated garbage to be recycled is handed over to a third party. Garbage that is not recycled is taken by the Local Government sanitation Department to be disposed of at the final disposal site. In addition, we also implement Life Cycle Management for used ink cartridge waste which is managed for recycling by returning it to the vendor.

          Environmental Certifications

          The Company maintains several environmental certifications on the fleet based on the International Convention for the Prevention of Pollution from Ships (MARPOL) for the protection of the environment, including:

          • The International Air Pollution Prevention Certificate (IAPP)
          • International Oil Pollution Prevention Certificate (IOPP)
          • International Sewage Pollution Prevention Certificate (ISPP)
          • International Ballast Water Management Certificate (IBWM)
          • International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substance in Bulk (IOPP NOx)
          • Anti-Fouling System Certificate
          • International Energy Efficiency Certificate (IECC)
