Projects Management

PrivatSea Projects - Yacht Refits, New Builds and Yacht Design

It all began in the early 80s when PrivatSea Projects was assigned, by Helsingor Vaerft, the construction of a super yacht designed by Maierform M/Y Abdul Aziz, and completed her outfitting at Southampton Docks, from here the future of yacht refits, build and design was birthed.

Independent of any shipyard, supplier or contractor, PrivatSea Projects can fulfil the requirements of the most demanding projects including yacht design, bespoke yacht builds and yacht refits. Our teams arrange cost-effective plans, ensuring the highest quality of work is completed on time and within budget. Our clients benefit from a wealth of knowledge and expertise in all disciplines as well as the benefits leveraged from our position as a Latsis Group member.

Yacht Design & Engineering

Below you will find examples of some of the projects in which we have been integral for yacht design and engineering during yacht refit and build stages, offering our expert advice to ensure the vessels are designed to maximise their full potential.


New 120m Yacht

Project Proteus is one of the world’s most impressive luxury yacht designs. Under PrivatSea’s project management, world-renowned designers, naval architects and marine engineers contributed to this impressive design to produce a yacht like no other. Her sleek exterior with a touch of turquoise mimics the rolling waves, and her interior reflects the finer things in life.


New 78m Yacht

Together with Azure Naval Architects and Lloyd’s Register, PrivatSea Projects embarked on a new design for a 78m Luxury Yacht. In accordance with the client’s brief, full GA, technical and engineering drawings, accompanied by exterior styling proposals, were prepared. All necessary drawings were approved by Lloyd’s and the package is complete for a construction shipyard to begin the creation of the vessel. Upon completion, the vessel exuded grace, fulfilling her owner’s wishes.


Conversion of a 77m salvage boat

The owner of a 77m ocean-going salvage tugboat requested conversion ideas from PrivatSea Projects. Our team prepared several options for the general arrangements and a full set of technical drawings and studies. Inclination tests and sea trials were performed to update stability and verify machinery condition. Exterior styling proposals and interior designs were presented by means of rendered pictures. The salvage boat was reborn to enjoy a new lease of life on the sea.


170m Yacht New Project

PrivatSea Projects was involved in the design process of a new 170m luxury yacht construction. Providing consultancy on the operational issues of the yacht, our valuable input was appreciated by the owner, the shipyard, interior and exterior styling designer and was a stable pillar in the construction of this magnificent vessel.

New Yacht Build & Conversion Projects

Below find examples of new yacht builds and conversions PrivatSea Projects have handled, each offering an insight into the bespoke services we can offer from overarching supervision to complete design and construction.


71m Private Yacht

PrivatSea Projects accomplished the delivery of the 71m yacht in just two years. Despite her size and her large engines, the noise and vibration levels achieved are considerably lower than the industry standards. This yacht can accommodate 26 people attended by 21 crew and seven staff. Such a large vessel calls for propulsion and auxiliary machinery on a commercial, rather than yacht, scale. Accordingly, the main engines are Wartsila diesel of 3,600hp each while the three MAN/Leroy Somer generators supply 480kW each. Just as with all of our projects, no detail went unaccounted for, resulting in the highest of standards.


116m Private Yacht

This vessel was built in Finland in 1990 as a cruise ship and spent most of her time as a floating casino. Given the vessel’s excellent construction, she was sold in January 2003 and moved to Greece. PrivatSea Projects had 14 months to complete the new designs and deliver the ship before the Athens Olympic Games in 2004.

The conversion project consisted of:

  • Complete stern-bow-funnel-mast modification
  • New bar, jacuzzi and helipad on sundeck
  • New Owner’s suite and 24 luxury cabins
  • New salons, dining and bar areas
  • New tenders and water toys
  • New AV and wi-fi systems
  • New foldable embarkation ladders and gangway

71m Private Yacht Lengthening

Our client’s requested that the two children’s cabins on the upper deck be transformed into a single, spacious suite and for new spaces to be created in the lower deck to accommodate four extra cabins. After careful analysis with the latest computer modelling technologies, we suggested that the upper and bridge deck should also be extended to maintain a balanced, sleek profile and the propulsion system be extended. After approval, structural drawings and cutting files were prepared by Azure Engineering (NL). Steel and aluminium works, including the demanding task of fitting the new shafts, were subcontracted to Elefsis Shipyards. All other works such as the interior outfitting, teak decking, stainless fixtures, deck head ceilings, fairing & painting as well as all necessary updates for regulatory and safety purposes, were managed by PrivatSea Projects, who supervised the assigned local Greek contractors.


Limousine Tender

PrivatSea Projects designed and constructed a custom-made limousine tender built to the specific needs of our client, a private yacht owner. At 8m long, 2.6m wide and 1.9m high, she can comfortably accommodate up to 10 passengers. Powered by two efficient and compact inboard-outboard engines (type Mercury Diesel QSD2.8-20S (220HP) with a Stern Drive BRAVO III X 2.00/1 and assisted by one “MAX POWER” bow thruster) the tender can reach an impressive speed of 35 knots. A lifting roof hatch allows for easy access to the spacious, fully air-conditioned cabin, which is also served by one chiller unit 15,000BTU/HR.

At Privatsea, we constantly strive to not just meet but exceed our clients’ needs.
