J+S Subsea strengthens Australian presence through partnership with Pulse Technology Hub

J+S Subsea is strengthening its presence in Australia and the wider Asia-Pacific (APAC) region through a new partnership with Perth-based Pulse Technology Hub

The partnership brings together J+S Subsea’s subsea controls, engineering and life extension capability with Pulse Technology Hub’s local market knowledge, experienced team, industry relationships and in-country facilities. 

The move follows six months of collaborative strategic market research and builds on J+S Subsea’s previous experience in Australia, creating a platform to develop further opportunities across the region.  

Supporting late-life subsea assets in Australia 

Initial market analysis has highlighted opportunities around late-life assets and ageing subsea infrastructure, where access to local support can help improve responsiveness and turnaround times for operators. 

The partnership will enable J+S Subsea to combine its existing engineering expertise with an established presence in Perth, providing greater access to local knowledge, facilities and support as the company develops its activities in Australia and the wider APAC market.  

It also creates further opportunities to apply the principles behind J+S Subsea’s Legacy Locker™ service in the region. 

Legacy Locker™ provides reuse options for existing subsea equipment, including the recovery of equipment otherwise identified for disposal. Components can be inspected, refurbished and re-certified where appropriate, helping clients access legacy equipment while supporting reuse, repurposing and the circular economy.  

Phil Reid, Managing Director of J+S Subsea, said: 

“Previous work in Australia has demonstrated to us the significant potential that exists not only in Australia itself, but across the wider APAC region. As we look to consolidate that experience and strengthen our position in this important market, it makes sense to partner with an established local name that brings knowledge, expertise and connections. 

“This is not just about extending our geographic reach but about developing the right in-country relationships that will allow us to meet the evolving needs of clients in the region. 

“Working with Pulse Technology Hub allows us to combine our strengths and create a platform from which we can capitalise on mutually beneficial opportunities, enhancing our offering to customers and delivering greater value.”  

Combining subsea expertise with local support 

Pulse Technology Hub works with international technology and service providers looking to establish and grow their presence within the Australian energy and resources sector. 

The Perth-based team provides market insight, business development support, local facilities and access to an established industry network, complementing J+S Subsea’s technical capability and experience in subsea controls and engineering.  

Ian Grant, CEO of Pulse Technology Hub, said: 

“J+S Subsea’s Legacy Locker™ approach aligns closely with the challenges Australian operators face around late-life assets, ageing infrastructure and the circular economy. 

“We see a genuine fit between J+S Subsea’s proven capability and the needs of the Australian market, and Pulse can help turn that potential into practical opportunities by providing the local relationships, market knowledge and in-country support needed to establish and grow here.”  

The collaboration has also been supported by Scottish Enterprise’s international trade team through its International Strategy Development programme.  

Karen Donnelly, International Trade Specialist at Scottish Enterprise, said: 

“Supporting companies to scale internationally is a priority for us, and it’s great to see the progress J+S Subsea Limited has made in recent months through our International Strategy Development programme. 

“The company is making an important contribution to Scotland’s energy transition through subsea decommissioning and, with our support, is realising its international growth ambitions in Australia and the wider APAC region. This partnership combines specialist expertise with in-market knowledge, and we look forward to seeing the opportunities it creates.”  

Looking ahead 

The partnership represents the next step in J+S Subsea’s plans to grow internationally while maintaining the responsive, practical approach that underpins its work with subsea operators. 

By combining engineering capability in the UK with local knowledge and support in Australia, J+S Subsea and Pulse Technology Hub will work together to identify opportunities where existing subsea infrastructure can be supported, maintained and kept in service for longer.
