Complete Fabrication Solutions (CFS) were a natural fit for a project of this importance, providing an integrated solution for DeepOcean.

THE BRIEF

The MAERSK CONNECTOR is the next generation POWER CABLE INSTALLATION VESSEL, specifically designed to transport and install large volumes of HVAC and HVDC power cable via its on-board 7000Te split capacity DUEL CONCENTRIC CAROUSEL.

CFS was the chosen fabricator to deliver a very complex and unique 35T chute configuration for the Maersk Connector. The project was made all-the-more challenging as it was to be manufactured alongside a 30T twenty-metre-long working platform for the MAIN TENSIONER WINCHES. Both fabrications were to be delivered to the quay side on a very tight schedule.

The Solution

In-order-for our client, DEEPOCEAN to deliver the cable from carousel to seabed, the leading edge of the chute was to be deployed part-submerged while on location due to the MBR of the cable. This presented the designers with some challenges as the vessel could not sail while the chute was in the water. Thus, they needed to design the chute so it could be removed while sailing to and from the field. Therefore, a complex hinge arrangement was designed to allow the chute to be lifted from the water during transit. This hinge encompassed high tolerance machined components which is not easy to achieve on large fabrications that are fixed to a ship's deck.

Daily client inspections were carried out during the fabrication to ensure the mobilisation run smoothly. Particular attention was paid to the inner smoothness of the cute due to past issues of cable damage.

At-A-Glance
SOME KEY FACTS

Full demob of existing vessel equipment
The largest permissible road transportation
Tight schedules and daily client inspections

THE RESULTS

The chute was fabricated entirely within the confines of the CFS facility and designed around the largest permissible road transportable dimensions along with the tensioner grillages. We were also contracted to carry out the full loadout and transport to Port of Blyth.

As part of the project we carried out the full demob of existing equipment in readiness for us to carry out the entire mobilisation of the chute and grillages.
