 SCOPE OF SERVICES
 Delta Marine provides a very detailed engineering service and design work on different types of ships such as,

   General Cargo Ships
   Containers
   Oil and/or Chemical Tankers
   Passengers Ships and Ferries
   Yachts
   Navy ships

 Throughout these designs Delta Marine realizes the conceptual design, feasibility analyses, technical specifications, basic and classification plan, detailed engineering of hull and outfitting, instruction books and manual preparation and interior design, during the whole design process of a ship.



 CONCEPTUAL DESIGN

At the early stages of the design process, Delta Marine determines the parameters that will form the basis for optimum ship dimensions, hull form as well as the selection of propulsion system's type and power and auxiliary systems, according to the customer's requirements (for example, speed, DWT, number of passengers, number of vehicles etc.). Concerning the conceptual design stage of the project, Delta Marine provides the services stated as below

Determination of main dimensions according to ship type, speed and carrying capacity
Preliminary form design
Speed-power analysis
Calculation of preliminary stability, trimmed and damaged stability conditions
Calculation of preliminary weight distribution
Calculation of longitudinal strength
Subdivision calculations
Preparation of preliminary general arrangement
Calculation of capacities
Feasibility studies
Preparation of Technical Specification Booklet


STRUCTURAL DESIGN

In Delta Marine, Engineers of Structural Design, who are experts on their subjects, prepare the optimum structural configuration of ship dimensions by taking the type of cargo and type of the ship as reference. Their aim is to use minimum amount of material, to comply the rules of Classification Society, to develop special details in critical areas of fatigue and corrosion, to develop the most suitable structural configuration for workmanship and vibration. They utilize acknowledged software such as, Classification Society Software (for example, Poseidon, Safe Hull, Mars etc.) and Finite Element Analysis Software for all these purposes. The scope of services of structural design includes,


Design of midship and typical transverse section details
Design of ship structure and preparation of general steel construction drawings
Preparation of shell expansion and framing system
Preparation of engine room, foundation of main engine and other machinery equipment
Preparation of fore and aft structural details
Design of signal masts and crane columns
Design of hatch covers and ramp


CAD / CAM

CAD/CAM Engineers and Draftsmen in Delta Marine work on the realization of the items cited as below

Lines fairing
Preparation of manufacturing sections
Preparation of block plans
Determination of building strategy
Design of the 3D structural model
Calculation of block weight and centre of gravity
Determination of element position numbers
Preparation of workshop drawings
Development of shell plates and preparation for cutting
Preparation of shell's bending model
Preparation of NC codes and nesting


MACHINERY, OUTFITTING & PIPING

Outfitting and Marine Engineers who have worked in ships for many years and who have a long onboard experience, develop projects on arrangements, outfitting and one-line diagrams of the main and auxiliary engines of the ship. During this arrangement process, their main aim is to provide safe, ergonomic and environmental designs. 3D model of piping layout and isometric drawings are among their experience.

Design and arrangement of engine room
Calculation of the equipment capacities and selection of equipment
Design of propeller and rudder shaft systems
Calculation of boiler capacity, heating coil length, design of heating systems
Design of ladder, railway, windlass-mooring arrangement and other deck equipment
Design and preparation of piping diagrams
Design of exhaust and ventilation ducts

Preparation of Fire and Safety plans
Preparation of Damaged Stability control plans
Preparation of docking and painting plans
Pressure Drop calculation for P/V circuits


ACCOMODATION DESIGN

Not only Marine Engineers are working Delta Marine for the realization of the design of ships but also architects are employed in the company in order to reach a fine, comfortable and functional design of accommodation. As far as the accommodation of the ship is concerned architects and engineers provide the services that can be resumed as follows,

Design of accommodations in accordance with function, status and regulations
Interior design of cabins, rooms, kitchen etc.
Design of furniture and details
Design of wetted volume
Preparation of fire, noise and heat insulation
