Cable Laying Services

In cable laying, Seaway 7 can perform the installation of inner-array grid cables (IAG cables); and export cables.

For the IAG cable installation works, we use the world’s most sophisticated, bespoke designed vessels to make sure that the product is laid safely, with precision, in all weather conditions. Cable Lay Vessels (CLV) Seaway Phoenix and Seaway Aimery, built in 2016, are fitted with the most modern equipment available to ensure that as few weather delays as possible are encountered during the installation campaign, giving our clients the schedule security that they need to complete their projects on time.

Seaway Aimery has two under deck turntables, giving a capacity of 4,250 tons of cable that can be arranged in split compartments to maximize offshore flexibility of installation sequence. Seaway Aimery has proven that it can safely lay cables in significant wave heights of up to 3.0m, while the cable hangar provides climate-controlled shelter for the crew during these operations.

Walk-to-Work Operations

The term ‘Walk-to-Work’ originates from the desire to offer offshore personnel the opportunity  to transfer to offshore structures without requiring them to first climb up a ladder or be transferred using a transfer basket on a crane.

Installation Support Vessel (ISV) Seaway Moxie was developed specifically to address this demand on offshore wind farms, where the pull-in teams on foundations and platforms were unable to access the structures in harsher weather conditions. Seaway Moxie was the first of her kind to operate in offshore wind farms in Europe. She was designed and built to allow offshore personnel safe access to foundations and platforms in calm and rough seas, making up to 54 successful connections and transfers in a 24 hour period; and able to work in up to 3.5m significant wave heights.

Cable Storage

Seaway 7 operates a logistic center and marine base in Eemshaven (The Netherlands), where we also provide storing facilities for submarine cables and related accessories.

We provide flexible cable storage solutions to clients, being able to utilize our existing facilities for various lengths, or by providing stand-alone cable storage solutions on a temporary or long-term basis at client convenient locations.
