GREEN MARINE TECHNOLOGY
Factories
Undershore Road, Lymington - (1,500 m2) Located to the east of Lymington River, this factory is predominantly used for the manufacture of one-off yachts. It has a fixed hull oven and a modular hull oven capable of taking mouldings up to approximately 80ft. Undershore Road also has a specialised moulding section with steel setup tables and small component ovens designed for construction of components requiring tight tolerances.
Spitfire Quay, Southampton - (2,800 m2) This is the largest of our factories, located on the eastern shore of the Itchen River. Having its own slipway, this factory gives us the ability to build yachts and superstructures up to 60m in length. It is also currently used for the production of the RNLI Tamar lifeboats.
Laminating Green Marine has moved through the generations of Epoxy based composite laminates; from vacuum consolidated wet lay-up, to wet-pregs, dry-prepregs and resin film infusion. All these systems are still in use depending on application. Typically racing yachts are 100% carbon skins on Nomex or aramid honeycomb core; cruising yachts are similar but with higher percentage of PVC or Corecell foam. The production lifeboats we build are also all epoxy pre-preg and film infusion on PVC and SAN foam.
Mould Tools We normally build timber female hull tools for custom yachts, and single skin glass or carbon moulds for production boats. All moulds are built to our own specification, developed through experience to remain dimensionally stable during long curing schedules at around 95°C.
Ovens We have both fixed and modular ovens in all factories to cater for yachts and components of any size or shape. The largest oven we have built to date being 48m x 11m x 7m high.
Ovens are fitted with Eurotherm controllers with temperatures monitored during the cure process using multiple thermocouples linked to a Pico logging system.
Autoclave We have recently acquired our own 4.95m x 1.85m clave, capable of 8 bar pressure. The main cure processes are similar to that of the ovens and they are computer controlled and logged in the same way. It is currently fully employed with yacht components such as rudders, canards, keel boxes, etc.
R&D Over the years we have worked closely with our materials suppliers in developing new materials and build processes. We do our own material and process testing aimed at developing new production methods for the future.
CNC Machines We are currently running two 3-axis cnc machines:-
• MultiCAM MG 204 with a 10’ x 5’ bed and an integrated vacuum bed and an eight head automatic tool changer. Mainly used for processing foam and honeycomb core, and for preparing wooden mould frames.
• Matchmaker & Bridgeport 4 axis CNC milling machines to undertake trimming and machining work on smaller components.
Our own workshops account for about 75% of the cnc shop capacity, with the remaining capacity being available for contract cnc work.
Quality Assurance All our workshops run to a ISO 9002 certified quality management system covering all aspects of the company operation. All projects whether production or one-off are managed using our own Work Instruction Sheets to ensure that all information is supplied to the shop floor in a clear and detailed format, and that materials used are recorded and traceable.
Health and Safety Green Marine are committed to an ongoing improvement programme to avoid accidents in our workshops, and to safeguard the good health of all our employees. We employ an outside consultant to audit, to advise and to assist with our training programmes.
