Spanish shipyard GONDAN has launched its largest vessel to date, a 120 metre Ocean Energy Support Vessel built for Norwegian owner Østensjø Rederi, the yard and industry reporting service MarineLink said on 11 September 2026.
The vessel, designated C513 OESV, was put afloat from GONDAN's Figueras facility in Spain. The launch marks a milestone for the yard, which described the unit as the largest it has constructed.
GONDAN's announcement to MarineLink noted the length of the new build at 120 metres and identified the vessel type as an Ocean Energy Support Vessel. The owner named in the report is Østensjø Rederi.
MarineLink reported that the ship left the slipway at the Figueras complex and will progress to subsequent stages of completion. Further technical and operational work was described as the next phase ahead of the vessel entering commercial service.
The launch represents a clear step in GONDAN's production capability. Reaching a 120 metre hull length extends the yard's output into larger vessel categories than it has previously completed.
Shipyard capacity and record build
GONDAN’s Figueras facility hosted the ceremony for the C513 OESV, underscoring the yard’s capacity to handle larger hull forms. The company’s decision to construct a vessel of this size for Østensjø Rederi constitutes the biggest single new build in its history as reported.
The designation C513 OESV identifies the unit as purpose-built to support ocean energy activities. The ship’s role and the owner’s choice reflect contracting activity for specialised offshore vessels.
Next steps after launch
Following the launch at Figueras, the vessel will undergo the remaining stages of completion before entering operational service. Those subsequent steps are standard for new builds of this scale and typically include outfitting and trials, the report stated.
The delivery of the C513 OESV will add a new asset to Østensjø Rederi’s fleet. The owner was named in the MarineLink report as the customer for whom the ship was constructed.
GONDAN’s progress with this project will be followed closely by the shipbuilding and offshore sectors. The build provides a reference point for the yard’s capability and for the market for specialised vessels designed to serve the expanding ocean energy sector.
The launch was recorded by MarineLink on 11 September 2026, which carried details of the event and the basic particulars supplied by the yard and owner. The paper reports the key facts of the build and the vessel’s status following the launch.
