Subsea cable engineering,
independently
delivered.

Soltech provides technical and programme management services for submarine cable systems across offshore wind, telecoms and energy — from initial concept to handover.

Three sectors. One discipline. 

Offshore wind

Inter-array and export cables, foundations and balance-of-plant support, since 2008.

Submarine telecoms

International data routes and enterprise telecoms programme management.

Oil & gas

Power umbilicals, cable design and subsea production system support — our founding market.

Working on a subsea cable project?

We'd be glad to talk it through - feasibility, route engineering, owner's engineer support or full programme management. 

About

Three decades of marine engineering judgement.

A small, senior team engaged directly by developers, contractors and investors on submarine cable programmes worldwide.

Solution Technology was formed in 1992 to provide technical and management services into the offshore oil and gas market, specialising in cable and umbilical design and application engineering. 

​

Soltech moved into the submarine telecoms market - providing project and programme management for marine operations on international cable systems.  The Solution Technology Group Ltd. was then incorporated in 2001.

​

Since 2008 we have applied the same discipline to offshore wind, supporting the deployment of submarine cables and foundations on projects across Europe. 

​

Today Soltech works as an independent partner - engaged for our judgement, not the size of our staff list - providing engineers and programme managers who have spent careers on the deck and in the design office to ensure full delivery of project objectives
