PASSER operates two subsea cable storage hubs serving offshore wind, oil and gas, and grid interconnector projects worldwide. Both facilities sit on deep-water quays for direct vessel access, with the equipment, crew and engineering support to handle cable safely across long storage periods and time-critical mobilisations.

Cable manufacturers and installation contractors use these hubs to hold export cable between manufacturing campaigns and offshore installation windows, to stage array cable for phased installation programmes, and to store reserve cable for long-term operations and maintenance contracts.

We handle the full range of subsea cable types and storage scenarios.

Export Cable

HVAC and HVDC export cable held between manufacturing completion and offshore installation windows. Typical storage periods range from a few weeks to many months, depending on installation programme timing.

Array Cable

Inter-array cable staged for phased installation across offshore wind farms with multiple delivery campaigns.

Spare Cable.

Long-term storage of reserve cable, repair joints and spare sections supporting operations and maintenance contracts across the asset lifecycle.

Umbilicals and Flexible Pipe

Specialist storage for umbilicals, flexible flowlines and other power and control cable variants used in offshore oil and gas.

Pre-Installation Holding

Short-term holding before transport to the cable lay vessel, often combined with PASSER LARS rental equipment for spooling and load-out.

Stored cable does not stay stored forever. When the mobilisation call comes through, both hubs have direct access to the PASSER cable handling equipment fleet, with carousels, loading towers, tensioners and ancillary equipment available for spooling, transpooling and vessel load-out.

Storage and mobilisation can be quoted together as a single scope, with FAT documentation, lifting plans and sea-fastening drawings provided as standard. Local engineering and supervising crew are available on request.

How Long Can Cable Be Stored?

Storage scopes range from short-term holding of a few weeks ahead of vessel load-out, through to long-term storage of reserve cable across multi-year operations and maintenance contracts. The Rotterdam and Taiwan hubs are both configured for long-term cable storage, with periodic inspection and condition monitoring available on request.

What Types of Product Do You Handle?

HVAC and HVDC subsea power cable, array cable, export cable, umbilicals and flexible pipe, across offshore wind, oil and gas, and grid interconnector markets.

How Quickly Can Stored Cable Be Mobilised to a Vessel?

Mobilisation timing depends on the vessel programme, the cable type and the destination. The Rotterdam and Taiwan hubs are both on deep-water quays for direct vessel access, with PASSER cable handling equipment available locally for spooling and load-out. Most mobilisations can be scheduled inside two to four weeks of the call.

Is the Stored Cable Insured?

PASSER provides secure quayside storage with 24-hour site access control. Cable insurance is typically carried by the cable owner or the project. Storage agreements set out the responsibilities for each party.
