Global marine and support transportation services provider SEACOR Marine has completed the installation of the first hybrid power solution on an offshore support vessel (OSV) in the Gulf of Mexico, following the upgrade of the SEACOR Maya OSV to hybrid lithium battery power propulsion.

“The successful installation of a hybrid power solution along with the first ever ABS OSV BATTERY-Li notation is a big milestone for our company,” said John Gellert, SEACOR Marine’s Chief Executive Officer.

“We have long believed that cutting edge hybrid power technology has the potential to improve vessel efficiency, while reducing fuel consumption and emissions by as much as 20%.

“Early indications from sea trials of SEACOR Maya put us well within reach of this target and validate the success of our investment.”

“The new hybrid lithium battery system will also help us improve safety, drive energy efficiencies and reduce our overall environmental impact.

“As governments tighten emissions standards, this technology will be a key competitive differentiator, leaving us well placed to take advantage of an upturn in the market.”

After a series of successful sea and failure mode effect analysis trials, the SEACOR Maya was issued its Interim Class Certificate from the American Bureau of Shipping (ABS) with additional notation BATTERY-Li, the first ever ABS OSV to have this notation.

The SEACOR Maya is currently operated by Mantenimiento Express Maritimo, S.A.P.I. de C.V. (MexMar), SEACOR Marine’s joint venture in Mexico.

SEACOR Marine contracted with ABS in March 2018 to class the SEACOR Maya as the first OSV in the Gulf of Mexico to operate using hybrid power.

Following the vessel’s successful modification to hybrid lithium battery power propulsion, ABS provided the additional BATTERY-Li notation for the SEACOR Maya in May 2018.

SEACOR Marine conducted the upgrade project on the SEACOR Maya at Bollinger Shipyards in Morgan City, Louisiana. Sea trials of the vessel were conducted in mid-May 2018.

SEACOR Marine, meanwhile, has also engaged with ABS to provide the additional BATTERY-Li notation on three additional OSVs operated by MexMar, including SEACOR Azteca, SEACOR Warrior, and SEACOR Viking.

The vessels are expected to be upgraded to a similar battery system as SEACOR Maya with the upgrade expected to be completed by September 2018.

SEACOR Marine will also install the technology onboard six vessels under construction at COSCO shipyard in Guangdong. The first two vessels are due for delivery by the end of 2018, with the remaining vessels set for delivery in 2020.

The lithium-ion-based Orca Energy Storage Systems (ESS) for all four vessels in the Gulf of Mexico was supplied by Corvus Energy.

Kongsberg Maritime designed the supply and integration of the hybrid power into the vessel’s control, power monitoring, and dynamic positioning systems. Corvus and Kongsberg are contracted for the remaining three vessels operated by MexMar as well.

Milestone

GCMD: Project CAPTURED achieves two regulatory milestones for onboard captured CO2

CO2 captured onboard during the project has been formally recognised for compliance under the EU ETS while a proposal submitted to MEPC 84, based on the project, has received IMO’s in-principle support.

Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (21 July) said Project CAPTURED has achieved two regulatory milestones that strengthen the commercial case for onboard carbon capture and storage (OCCS).

This comes following its world’s first demonstration of an end-to-end value chain for onboard captured and liquefied CO2 (LCO2).

Completed in June 2025, the pilot showed that CO2 captured onboard a vessel can be offloaded ship-to-ship, transported overland and permanently bound through carbon mineralisation—a process that converts captured CO₂ into stable materials for industrial use.

The CO2 captured onboard during Project CAPTURED has been formally recognised for compliance under the European Union Emissions Trading System (EU ETS). This means the verified tonnage of captured CO2 can be deducted from emissions requiring the surrender of EU Allowances (EUAs).

To qualify for this recognition, the CO2 must be chemically bound permanently in eligible products. Project CAPTURED demonstrated that CO2 captured onboard vessels can meet this requirement through carbon mineralisation.

The data and learnings from the same demonstration formed the basis of a proposal submitted to MEPC 84. This proposal received in-principle support from the International Maritime Organization (IMO) for recognising carbon mineralisation as a form of permanent CO₂ storage.

Complementing geological sequestration, which is already accepted by the IMO, this recognition broadens the downstream options for CO2 captured onboard vessels, and supports the development of maritime carbon value chains. Beyond providing a permanent storage pathway, carbon mineralisation also creates the potential for captured CO2 to serve not only as a waste stream requiring permanent storage, but also as a feedstock for industrial applications through carbon mineralisation, extending emissions reductions beyond the shipping value chain.

Professor Lynn Loo, CEO, GCMD, said, “Project CAPTURED has moved OCCS beyond technical demonstration. The acceptance of the EU ETS deduction gives captured CO₂ a compliance value. At the same time, IMO’s in-principle support for carbon mineralisation will help clarify how captured CO2 can be treated after it leaves the vessel. Together, these milestones turn a pilot into a verified reference case for maritime carbon logistics, one that links regulatory recognition, commercial value and emissions impact.”

Singapore: Ofiniti, ONE trial direct platform integration to streamline bunker workflows

Ofiniti, the digital platform for maritime fuel operations, on Tuesday (21 July) said it has started a trial in Singapore, integrating FuelBoss directly with a bunker buyer’s own platform.

The company announced Singapore-headquartered container shipping firm Ocean Network Express (ONE) as its first buyer-side integration partner. 

“It is no coincidence we start in Singapore, as the Maritime and Port Authority of Singapore (MPA) remains at the forefront of digitalisation of all things bunkering,” the company said in a social media post.

In November 2023, MPA launched its digital bunkering platform, becoming the world’s first port to implement e-BDN. 

Ofiniti said every bunker delivery still runs on retyped data. 

“The buyer’s system says one thing, the supplier says another, and someone reconciles the gap by email, phone, or PDF. On every stem,” the company said. 

“We built FuelBoss to change this reality.”

With the integration, operational data now flows without manual re-entry, fewer reconciliation errors and faster processing and data, instead of documents, are readily available for procurement and claims workflows. 

“One connection will not transform the industry on its own, but digitalisation gets built one integration at a time. We are grateful to ONE for being willing to go first,” Ofiniti added.

Manifold Times previously reported ONE completing its successful trial of the electronic Bunker Delivery Note (e-BDN) with Shell. 

The e-BDN trial, using the digital bunkering solution developed by Angsana Technology, was conducted on 9 September 2023 at the Port of Singapore, with support from the MPA.

In March 2025, Ofiniti acquired Singapore-based Angsana Technology, with the entire Angsana team joining Ofiniti as part of the acquisition.
