High-spec reel lay vessel promises to set new industry standard

The design between Royal IHC and Subsea 7 incorporates several innovative features which focus around compact dimensions and the smart use of space. It’s the first Subsea 7 vessel to be equipped with a pipe lay system designed, engineered and built by IHC.

“We are very proud of the confidence that Subsea 7 has placed in IHC. Our integrated approach to vessel design will give Subsea 7 an industry leading asset that sets a new standard in offshore pipe lay,” said Dave Vander Heyde, CEO, Royal IHC.

“Based on the ratio between top pipe tension and payload to displacement, this will be one of the most cost-effective vessels to enter the market.”

The vessel’s compactness is achieved by the creative positioning of its three engine rooms and main reel, efficient use of the superstructure and low-profile pipelay ramp.

The smart use of space opens a large aft working deck, whilst the optimised mass distribution minimises the ballast water requirement.

In addition, the design of the reel lay system focuses on operational efficiency and flexibility, alongside crew safety. The twin tensioner pipelay ramp tilts to allow pipeline installation from shallow waters to depths of up to 3000m.

Its large multi-level workstation optimises the efficiency of operations in and around the firing line, whilst a fixed auxiliary reel, recessed into the main deck, gives payload flexibility.

Royal IHC has delivered a total of eight vessels to Subsea 7 in the course of their longstanding relationship.

Delivery of the vessel is planned for early 2020.
