LD Armateurs buys three PSVs for cable-lay conversions

French shipowner LD Armateurs (LDA) has bought three platform supply vessels, still under construction, and will convert them into cable-laying ships with delivery scheduled for Q2 2027 and entry into service in Q1 2028.

Each converted vessel will carry 2,800 tonnes of cable. The ships will be equipped for subsea cable installation, maintenance and repair — the full work scope of a telecom cable operator. All three will run hybrid-electric propulsion systems, which LDA says will improve fuel efficiency and cut emissions.

After delivery in the second quarter of 2027, the trio heads to an undisclosed shipyard for conversion work. That timeline puts them in service by the first quarter of 2028.

Why is LDA adding cable-lay tonnage now?

The company frames the deal as a response to structural tightness. LDA, which counts more than 25 years in subsea telecommunications cable operations, says the investment addresses growing demand for cable installation and repair capacity against the backdrop of an ageing global fleet.

That argument carries weight. Subsea cable demand is rising on data-centre interconnection and backbone renewal, while much of the existing installation and repair tonnage dates back years. New entrants and incumbents alike are scrambling for capable ships.

LDA knows the conversion route. It converted the Ile de Molène, which entered service with Alcatel Submarine Networks in 2022 after an extensive refit programme. Buying PSV hulls under construction and rebuilding them for cable work is typically faster and cheaper than newbuilding slots in a crowded yard market.

The latest move follows the September delivery of the DP2 multipurpose support vessel TVO Mariner to LD TravOcean, LDA's subsidiary specialising in subsea cable installation and protection. The three PSV conversions deepen that franchise.

What else is changing at LDA?

Alongside the ship purchases, LDA is launching a training academy to support recruitment and crew development across an expanding fleet. Specialised cable-lay crews are scarce; building training capacity in-house is a logical hedge against a tight labour market for marine personnel.

The academy will also support the arrival of three methanol-capable, wind-assisted ro-ro ships under construction for Airbus logistics operations. The first of those, Spirit of Toulouse, has just completed installation of six Norsepower rotor sails.

So LDA is pushing on two fronts at once: subsea cable capability through conversions, and low-emissions surface logistics through methanol-ready, wind-assisted ro-ros serving aerospace supply chains.

What does it mean for the market?

For charterers and cable system owners, three additional 2,800-tonne-capacity vessels arriving in early 2028 add meaningful installation and repair capacity to a fleet the industry widely regards as ageing. More tonnage could ease scheduling pressure on repair contracts, where response times are contractual and ships are few.

For shipyards, the deal confirms steady demand for conversion slots, not just newbuilds. And for competing owners, it signals that conversion-led fleet renewal — proven on Ile de Molène — remains LDA's preferred path.

With deliveries set for 2027 and service entry in Q1 2028, the subsea cable market now has a firm date for when new French-flagged capacity lands. Expect rivals to answer with conversion orders of their own before then.
