BHP looks to LNG for lower iron ore shipping emissions

BHP, as part of its goal to reduce greenhouse gas emissions across its operations, has released the world’s first bulk carrier tender for LNG-fuelled transport for up to 27 Mt of its iron ore.

The company said: “Introducing LNG-fuelled ships into BHP’s maritime supply chain will eliminate nitrogen oxide (NOx) and sulphur oxide (SOx) emissions and significantly reduce CO2 emissions along the busiest bulk transport route globally.”

BHP, as part of its greenhouse gas emission reduction plans, recently signed a memorandum of understanding with Mitsubishi Development to work together in the pursuit of emissions reductions, including from the life-cycle use of marketed products.

Rashpal Bhatti, Vice President, Maritime and Supply Chain Excellence, BHP, said emissions resulting from the transportation and distribution of the company’s products represented a material source of its value chain emissions (Scope 3).

“We recognise we have a stewardship role, working with our customers, suppliers and others to influence emissions reductions across the full life cycle of our products,” Bhatti said. “Through this tender, we are seeking potential partners who share our ambition of lowering emissions to the maritime supply chain.”

The tender is open to a select group of industry leaders, from ship owners, banks and LNG fuel network providers, BHP said. “As well as LNG-fuelled transport for up to 10% of its iron ore, the tender seeks other innovative solutions that can lower greenhouse gas emissions and increase productivity from BHP’s freight requirements.”

Bhatti added: “We are fully supportive of the International Maritime Organisation’s (IMO) decision to impose lower limits on sulphur levels in marine fuels.

“While LNG may not be the sustainable homogenous fuel of choice for a zero carbon future, we are not prepared to wait for a 100% compliant solution if we know that, together with our partners, we can make significant progress now.

“This new tender adds to the work BHP is doing with customers, suppliers and parties along our value chain to influence emissions reductions from the transport and use of our products.”

The IMO ruled from January 1, 2020, that the marine sector will have to reduce sulphur emissions by over 80% by switching to lower sulphur fuels, with the current maximum fuel oil sulphur limit of 3.5 weight percent (wt%) falling to 0.5 wt%.

As well as investments in emerging technologies, BHP sets greenhouse gas emissions reduction targets for its operations, builds the resilience of its operations and communities to the physical impacts of climate change, and works across sectors to strengthen the global policy and market response, the company said.

Drones go to sea at BHP’s ocean freight operations

BHP was an early adopter of drones across its mine sites, employing the aerial technology across the group for post-blasting clearance, traffic monitoring, building inspections and operation surveillance. Now, the major diversified miner is looking to drones to improve safety and provide efficiency gains at its ocean freight operations.

While still in the trial phase, BHP’s Vice President of Marketing Freight, Rashpal Bhatti, sees the potential for drones to be a key part of a tablet-based technological package, incorporating artificial intelligence that provides captains a digital view of their ship.

“All of our chartered ships receive a tablet when they berth. And on the tablet they can read the tension of the mooring line which has major safety benefits,” he said.

“The question now is: can the same tablet become a holistic technological package by also delivering ship hold inspection data, draft readings and other critical information captured by drones? It’s all a bit futuristic but that is the direction we are going.”

BHP ships more than 300 Mt/y of iron ore, coal and copper to customers around the world. More than 1,500 voyages are made, making BHP one of the largest charterers of dry bulk carriers in the world.

Like the drones being used across other parts of BHP’s operations, marine drones can be programed to carry a range of specific tasks, the company said.

“In the ocean freight business, there are clear and immediate advantages from using drones in the inspection of holds and in the taking of draft readings. Then there is their nimbleness in the seemingly simple but important task of advising the ship’s bridge on the water position of the rudder,” BHP said.

Hold inspection reports would continue to be independent assessments, but the use of drones promises to cut inspection times per hold from an hour to 15 minutes, according to the company.

Bhatti said: “The hold inspection process involves ships which have five to nine holds which a person checks by climbing down ladders. The inspector has to be physically fit, use fall protection, and carry a parrot (oxygen meter) to make sure there is enough air in the hold. And it takes a lot of time.

“With drones, we can fly them into a hold and capture 4K images, but also infra-red, and other types of cameras that can show cracks or other specific parameters that cannot be seen with the naked eye.”

There are essentially three or four types of ships with hold sizes about the same, according to Bhatti. “So once you programme a drone to go in to a certain ship, it can become an autonomous process.’’

This provides a better way to assess the condition of the hold, and removes a person from a potentially hazardous situation, Bhatti said.

BHP is also testing the use of drones to improve the safety, time and cost of ship draft readings. This is usually done from a boat when the ship is berthed and ready for a cargo.

One of the logistical challenges to overcome is to get the drones on ships when they are offshore at anchorage, as distinct from being berthed.

“We are working with ship owners on this and other ways to use technology to improve safety and productivity,’’ Bhatti said.
