**Submission deadline extended to 30 June 2020**

A global competition to design an innovative rescue boat hull, leveraging the power of Additive Manufacturing.

The competition aims to encourage innovative design conceptualisation of a rescue boat hull that can be manufactured by Additive Manufacturing techniques of Wire Arc Additive Manufacturing (WAAM) or Continuous Composite Fabrication Technologies, which are seen as key game changers in the future of the naval architecture and marine engineering.

  1. Develop new efficient designs for lifeboats utilising the advantages of AM to create a more compact vessel, better designed for human rescue in difficult waters.
  2. Utilise AM to embed sensors that allow real-time condition monitoring and can assist qualification of the vessel. Explore the use of the sensors to monitor rescued human condition.
  3. Ensure the design that fits inside a container and hold two persons lying down. Allow for easy transport, but also installation on larger vessels, oil platforms and deployment in near shore rescue.
  4. Install autonomous systems on the lifeboat that eliminate the need for manned rescue. The vessel must able to withstand dangerous North Sea conditions.
  5. Develop a method to qualify the vessel within regulatory constraints to ensure the vessel is safe and sea-worthy.

Rules and guidelines


  1. Comply with the LSA (Life Saving Appliance) code, SOLAS (Safety Of Life At Sea) and Singapore Flag State requirements as deemed appropriate. Deviation is allowed for innovation to happen.
  2. Rescue boats shall not be less than 3.8 m and not more than 8.5 m in length
  3. The regulations require the capability for a stretcher and seating for 5 people
  4. Must have power for 4 hours continuous operation and must have a minimum speed of 8 knots
  5. A rescue boat must be able to operate in Beaufort 6 sea states and there are rare cases where the use of a crew is a significant additional risk (maybe situations such as a large acid/chemical spill).


  1. Hull design shall be scalable to account for different number of people saved, 2 and 3. As a minimum, the design should accommodate one person lying flat
  2. Propulsion and control surfaces be reasonably covered and shall not pose any danger to humans during the entire recovery operation phase
  3. Hull design should be reasonably buoyant and self-righting to withstand distressed perturbations as the person climbs on-board the vessel.
  4. Top-side design shall take into account perception and localization sensor installations to support autonomous homing towards any person-in-water. The design shall allow for mounting of the specified sensor mast for autonomous operation. – ST to provide info on autonomous mast: mounting specifications etc.
  5. The vessel shall have necessary compartments to store life-saving equipment, rations and drinking water to sustain 2 persons for up to three days.
  6. The vessel must be quickly and easily deployed and recoverable.  Conventional davit systems will be used.
  7. Designers are encouraged to take advantage of the design freedom and advantages that additive manufacturing techniques allow.
  8. The vessel is intended to be class certified after manufacture

Performance Requirements

  1. Shall ensure safe transfer of person in water under dynamic conditions;
  2. Shall protect the persons in water against risk of injury from impact with the vessel’s side or other structures;
  3. Shall be designed for rescue persons incapacitated.
  4. Shall ensure that persons in the water can be simply secured, and prevented from dropping or sliding out of the craft after rescue due to dynamic motions;
  5. Shall be of sufficient strength to enable safe recovery to parent vessel when fully loaded with causalities;
  6. Shall have a launching time not more than 5 minutes ;
  7. The craft shall be self-draining and shall have a freeboard of 30 cm.


  • The vessel can be constructed using Wire Arc Additive Manufacturing or Composite Continuous Fibre Manufacturing.
  • Vessel will be class certified after manufacture.

Wire Arc Additive Manufacturing


  • Utilising aluminium as the deposition metal.
  • Thickness limitation on a WAAM only finish (non-machined) is 5mm thick
  • Tolerances are 0.1mm.
  • No limitations on curvature, however there is a limitation on the build direction of 45 degrees either side of vertical. Although a rotatable jig may also be utilised to reduce any further limitations.
  • Material Specifications of WAAM Aluminium:

Composite Continuous Fibre Manufacturing

  • Utilising different grades of fibreglass in a polymer matrix. The Process deposits a unidirectional fibre, Mechanical properties depend on the fibre orientation.
  • Mass deposition rate is dependent on fibre size and complexity of path:
    1. 600TEX:: Fibre section width: 1.4mm, layer height : 0.4mm. (max 400 g/h)
    2. 1200TEX: Fibre section width: 2.5mm, layer height: 0.5mm. (max 800 g/h)
    3. 2400TEX: Fibre section width: 4.2mm, layer height: 0.6mm. (max 1600 g/h)
  • No Thickness limitations. Fibres can be used together to reach desired size
  • Minimum curvature is double of fibre width. Minimum extrusion length of 20mm.
