    Royal IHC confirms contract for Subsea 7 reel lay vessel

    Yard News // October 2, 2017

    Royal IHC has confirmed that it has signed a contract with Subsea 7  for the design and build of a new reel lay vessel. The vessel will be capable of installing complex rigid flowlines including pipe-in-pipe systems.

    The shipbuilder said that, in close cooperation with Subsea 7, IHC has incorporated several innovative features to make this "the most technologically advanced vessel to date."

    The vessel’s compact dimensions are facilitated 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.

    With model tank testing already having been performed, Subsea 7 can be confident that it will receive a vessel from IHC that excels in performance, both in transit and in DP conditions, and provides maximum comfort for the crew.

    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 3,000m.

    The 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.

    Delivery of the vessel is planned for early 2020.

    Dave Vander Heyde, CEO Royal IHC, said "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.”
