Conversion of Gateway Endeavor to an Offshore Wind Farm Crew Transfer Vessel

The maritime industry is evolving with the increasing focus on renewable energy. Hornblower Marine, in collaboration with Windea CTV LLC, has recently completed a significant project: the conversion of the vessel Gateway Endeavor from an oil field crew boat to an offshore wind farm crew transfer vessel (CTV). This transformation demonstrates the capability and innovation of Hornblower Marine in adapting vessels to meet the specific needs of the renewable energy sector.

Project Overview

Originally constructed in 1985, the 125 ft. Gateway Endeavor has been repurposed to serve as a CTV, specifically designed for the operational requirements of offshore wind turbine installations. The comprehensive conversion process was carried out by the Hornblower Marine team on-site in Bridgeport, CT.

The modifications include:

  • A new bow transfer platform
  • An electronically driven bow thruster
  • Forward and aft fendering systems
  • Digital throttle controls
  • Removable railings
  • An entirely new electrical system
  • Additional seating for crew members

Notable Features

  •    Classification: USCG Subchapter T
  •    Fendering System: Buoyant Works Wide Cup adjustable fender
  •    Passenger Capacity: Up to 16
  •    Dec Cargo Capacity: 50 tons
  •    Helicopter Winching Area
  •    Main Engines: 4x Cummins KTA 19
  •    Generators: Detroit 4-71 & John Deere 4045
  •    Bow Thruster: 1x 125 HP AC motor

Conversion Details

BOW TRANSFER PLATFORM AND BOW THRUSTER

The addition of a new bow transfer platform and an electronically driven bow thruster enhances the vessel’s maneuverability and efficiency in transferring crew and equipment to offshore wind turbines.
FENDERING SYSTEMS

The installation of forward and aft fendering systems, specifically the Buoyant Works Wide Cup adjustable fender, ensures the safety and stability of the vessel during docking and transfer operations.
DIGITAL CONTROLS AND ELECTRICAL SYSTEM

Upgrading to digital throttle controls and a new electrical system improves the vessel’s operational efficiency and reliability, aligning with modern maritime standards.
INCREASED CAPACITY AND COMFORT

The addition of removable railings and extra seating provides increased capacity and comfort for the crew, allowing the Gateway Endeavor to transport up to 16 passengers and carry a deck cargo capacity of 50 tons.

Operational Impact

Renovating and modifying the Gateway Endeavor vessel added the capacity to allow Hornblower to provide services to the emerging US Wind Farm market. The additions of the bow and stern transfer platforms, crew seating, bow thruster, and new engine control system allowed the Gateway Endeavor to facilitate a broader range of services and take an existing vessel back into service sooner than the newly purpose-built vessels she sails with.
