Life at Sea Projects

The profile above-shown, indicates a preliminary drawing from a series of completed concept design drawings produced to study deck and cabin arrangements, suited for residences at sea. The final versions involve client particular requirements.

The image below represents a series of visits to shipyards and newly built cruise ships initiated by Capt. E. G. da Costa Duarte to assess practical aspects of internal layout suited to a lifestyle at sea. 

Introduction

The cruise liner incorporating Luxury Residence Estates with Passenger Staterooms where the two occupy segregated deck spaces has yet to materialize. A variety of clients engaged the expert services of E. G. Duarte & Associates to study the possibility of building luxury floating palaces where individuals or companies can enjoy world travel on a continuous basis. This attitude brings to light international communities separated only by distances and not by communications. Certainly, the world offers many exotic places to visit allowing enjoyment from cultural variety.

Because the subject is large in scope, E. G. Duarte & Associates reserves its large data file for potential clients wishing to study the feasibility of such projects.

General Particulars Involving the Panamax-Max Hull

The following particulars have been compiled to assist shipyards assessing this type of project. The hull dimensions derive from Panamax-Max cruise ship size hulls already in service. Final dimensions will be established during detail design stage. With the exception of the Gas Turbine power plant system (COGES) the shipyard is free to recommend equipment and suppliers suited for this size hull and Class requirements. Where the (?) symbol is shown, it describes a subject that is under study or remains open for future input/suggestions.

The COGES system (Combined Gas and Steam Turbine integrated with an Electric Drive System). An environmentally friendly and smokeless plant using power from three alternators: two 25MW units driven by aero-derivative General Electric gas turbines and a 7.8MW alternator coupled to a Fincantieri steam turbine. The steam turbine receives its steam from exhaust-gas boilers fitted in the gas turbine exhaust lines. Of the approximate 57.8MW generated, 40MW is available to drive two Azipod 360 degree azimuthing podded propulsors suspended under the stern, port and starboard. The machinery installation will include excellent maneuvering qualities assisted by three tunnel type bow thrusters together with the Azipods controlled from the bridge joysticks, forming part of a dynamic positioning system, which can be used with automatic berthing.
