Description

Futures Afloat is a project that includes the replacement of Trinity House’s ageing multi-functional buoy handling tenders (MFTs). the scope of this procurement includes the construction of modern multi-function buoy handling tenders that will replace THV Patricia as a priority and subsequently THV Galatea. A replacement for THV Alert is within scope of the Futures Afloat project but is out of the scope of this procurement. Futures Afloat is intended to drive a strong competition through a pipeline of ship building activity based on THV Patricia and THV Galatea sharing a common design along a defined timeline. THV Alert will require a separate design and timeline.

Total Quantity or Scope

THV Patricia and THV Galatea are MFTs. Their functions include: to service and periodically renew England & Wales’s 450 navigation buoys and other aids to navigation; locate, mark and protect shipping from dangerous wrecks; and to contribute to hydrographic surveys. THV Patricia is reaching the end of its serviceable life and could suffer enduring non-serviceability at any time. THV Galatea will be approaching 25 years of service by the time it is replaced. Modern technology and a requirement to operate more energy efficient, low carbon emitting vessels accelerate its potential obsolescence and the need for its replacement. This procurement is intended to identify and appoint a contractor to design, construct and deliver the required replacement vessels. As a result of a thorough review of design and capability requirements, Trinity House envisages the procurement of a multi-function buoy handling tenders with the following basic characteristics: • Capable of handling largest type 1 steel buoys with tail tube fitted • Twin Head multibeam hydrographic suite • Boat launch and recovery (Fast and work boat) in a seaway • Capacity to tow a lightvessel. • Helicopter deck • Improvement in sea keeping and fuel saving • Diesel / Electric hybrid with overnight (12hr) hotel load on battery (Quiet running). Ability to take shore power. • Improved hull performance compared with the existing THV Galatea maintaining speed in poor sea conditions. • Max Draught 4.5m • The following changes have been made from the design in the previous tender: • Cabin reduction to 36. • Remotely Operated Vehicle (ROV) garage requirement removed. • Helicopter-deck size increase to future proof against airframe size increase. • Diesel Electric Hybrid main engine(s) but Methanol fuel ready. • Increased working deck size using Galatea working deck size as a baseline. • Vertical replenishment operations capability from working deck. • Main propulsion provided by two Azimuth Thrusters – increase in market appetite to install such propulsion equipment and benefit of freeing up space in the hull. • Service speed of 13knts in 2m Significant Wave Height with one engine out of service to offer resilience. • Deck Height reduced to 2200mm.
