Energy efficiency enables us to remain competitive

At BW LPG, caring for the environment goes beyond being compliant with regulations; it is a fundamental element of our core values. We are committed to keeping the future of our planet in mind wherever we do business

A significant part of our operations are directed towards achieving fuel efficiency and reducing emissions. We have invested in technology to help reduce our environmental footprint. These initiatives will enable us to manage the environmental impact of our operations while providing competitive energy solutions to our customers.

Our Approach

BW LPG’s fleet is ISO 14001 certified. We have taken a holistic view on energy management involving the entire organisation and are committed to implementing processes and measures that will continually reduce our impact on the environment.

Reducing Emisions

Steadfastly complying with Low Sulphur fuels in Emission Control Areas around the world

Enabling discharge terminals to return cargo vapours to vessel to create a closed ship to shore system thereby cutting down the emission of hydrocarbons to atmosphere

Cost Focus

Utilising Mass flow meters for the delivery of bunkers at select ports; Testing each stem of bunkers for quality control

Ensuring we carry inventory of fuel oil optimised for each voyage and nothing more, thereby minimising deadweight


Driving a performance mindset across the team to enhance availability, utilisation and cost awareness

Being agile in all aspects of Operational and Technical management; Utilising voyage obligations to maintain optimum speeds


Abiding to the highest benchmarks of Tanker Industry Health, Safety and Environmental standards

We monitor our CO2 emissions and remain well prepared for the upcoming European Union’s CO2 Monitoring Reporting and Verification (MRV) regulation and International Maritme Organisation’s CO2 Data Collection System (DCS). BW LPG is a member of Workgroup 5 for environmentally friendly shipping (WG5).

WG5 consists of five leading shipping companies such as BW, Klaveness,Wilhelmsen, Grieg Star and Solvang Shipping Group. WG5’s purpose is to make a contribution towards the Norwegian Shipowners Association’s environmental vision of “Zero harmful emissions to air and sea.” We meet regularly to benchmark our environmental efforts and performance.

We also evaluate the enviromental performance for all newbuildings which includes hull and propeller design machinery choice of antifouling system, instrumentation that can improve our fuel performance monitoring and fitting of energy saving devices such as Mewis Ducts and Propeller Boss Cap Fins.

The Company ensures all newbuildings support energy efficient operations, enabling our assets to remain competitive in the market.

We have in place a comprehensive, holistic energy management programme that spans across the organisation, from commercial to technical, involving various stages of planning and implementation, aligned with our identified objectives.

“Only with careful and continual monitoring of fuel efficiency will we achieve the desired optimisation,operational costs and a tangible reduction in environmental impact.”

Operational effectiveness in fuel management

Procuring bunkers for each of the fleet vessel is just one functional aspect of operations. We strive to go beyond, on every occasion and ensure that we carry the ideal inventory of fuel oil on board at any one time. Carrying just the right amount of fuel ensures we maximise on cargo carrying capacities and reduce transporting excessive ‘deadweight’ during long voyage legs.

We work to achieve the ideal combination of optimised costs and a tangible reduction in our impact to the environment.

  1. A steadfast approach to getting the best quality fuel, meeting both environmental and technical criteria, and at the most economical price globally. We employ Mass Flow Metered barges for all bunker deliveries where available.
  2. Ensuring that our vessels are appropriately stocked with the optimum inventory on board. Our contracts include laden voyage bunkering options, allowing for minimum bunker inventory.
  3. Monitoring daily service consumption to ensure that machineries are at peak performance; promptly alerting the vessel and her technical superintendent to attend to inferior performance. Operators scrutinise daily reports from the vessels as well as end of voyage reconciliation of bunkers remaining on board.
  4. Routing sea voyages through a path of least weather resistance. Professional weather routing services are utilised for every trans-oceanic voyage.
  5. Endeavouring to arrive in ports just in time, to avoid near shore idling and emissions.

Communication is key to achieving these objectives. Ship managers, charterers, port agents, brokers and vessels are all kept closely aligned both during pre-fixture commitments and during the post fixture voyage execution. Operations form the hub for this activity.

A modern and fuel efficient fleet

By investing in newbuilding programmes with HHI and DSME, BW LPG has enhanced its VLGC fleet with the addition of 12 brand new, fuel efficient carriers. These vessels enable us to deliver fuel efficient and competitive transportation services to our customers on a global basis.

In addition to improved hull and propeller designs, state of the art hull coating and energy saving devices, BW LPG’s newbuildings are equipped with:

All eight ships from HHI are enrolled into Jotun’s Hull Performance Service.

“We took delivery of state of the art newbuildings, setting a new standard in fuel efficiency for this type of vessel. These vessels allow us to deliver fuel efficient, high performance services to our customers.”

Mewis Duct Installations

Fuel cost: USD 250/mt Average saving laden: 7% Average saving ballast: 6% Payback time: 2.6 years

Propeller Boss Cap Fins

Fuel cost: USD 250/mt Average saving: 2% ballast/laden Payback time: 1.9 years

CO2 emissions are proportionally linked to the reduction in our vessels’ fuel consumption. Since the energy management project started in 2011, our carbon footprint has been reduced by 20%.

We managed to maintain carbon dioxide tonnes per nautical mile as the same level as 2015. This can be attributed to the applications of various energy reducing solutions continued in 2016.

We aim to reduce our sulphur oxide emissions through the purchase of bunker with reduced sulphur content.

We saw a small increase in emissions between 2016 but have overall reduced sulphur oxide emissions buy 22.6% since 2013.

All vessels are equipped with compactors and we avoid using disposable plastic bottles for drinking water.

We communicate regularly with our ship handlers about reducing the amount of plastic waste landed by our vessels.

All landed plastic waste is disposed for recycling.
