Ships in Service

No matter the level of upkeep, vessels require regular reviewing to maintain levels of comfort, safety, and compliance. 

The McFarlane ShipDesign Team services yacht management companies as well as individuals,

and we travel anywhere in the world to handle a ship or yacht's services.

The unit cost per m2 of a yacht or cruise ship is many time more than that of a building, and the unit volume per person on a ship is many times smaller than that of any prestigious hotel or residence. The required balance lies between an optimization of space usage whilst retaining an efficient and appealing vessel which can be profitable if chartered.


We handle the following challenges: Aesthetics, Naval Architecture, Interior  Technical, Engineering, Accommodation.




Technical specifications are documents which delineate the project in hand to prospective yards, suppliers, and to the owner. 

Technical specifications are sizeable, detailed, and cover everything from structure to systems. Our experience is that they need to be of the highest, most detailed grade to ensure the desired end product without unnecessary price inflation, misunderstandings, or delays.



Structure Plans can be described as the skeleton of the ship. This is not deduced but asserted via minute calculations. Having the proper structure on your ship, as well as correct structure plans, is primordial.

Our team of naval architects, engineers and stylists work together with a client's vision to produce the ideal and durable building blocks for any vessel type.



We use long-range scanning and laser technology in our work and data calculations to ensure accuracy and fit. With it we can offer a wealth of CT services: from hull modifications and reverse engineering to solving onboard issues without invasive procedures, to recreating life-like representations of visible, semi-visible, and non-visible vessel components (engine rooms, valves, hull interior,etc) for simulations. 

We can then either draft up solution plans, or execute them immediately.



We deal with all systems, and can be on location at a moment's notice. 

We propose consultancies,  solution plans, as well as onsite investigation and surveying for conceptual, preliminary, detailed analysis and troubleshooting.

 Examples of systems:

  • Propulsion systems; Classic, Diesel Electric or Hybrid

  • Heating Ventilation & Air Conditioning (HVAC)

  • Bilge & Fire Fighting

  • Ballast water treatment

  • Tank Sounding & Venting

  • Domestic H&C water systems

  • Sanitary drainage & Sewage treatment systems 



Services include:

  • Development of ship hull forms and stability analysis both for intact & damaged stability, including problematic stability

  • Preparation of stability booklets

  • Assessment of vessel's stability

  • Stability book review

  • Specialist loading conditions, eg. Events and parties

  • Design and implementation of stability compliance solutions

  • Weight & stability management plans 


McFarlane ShipDesign is always in compliance with the IMO SOLAS, ISO, MCA, ABS, Lloyd's Register, and all other leading regulatory bodies.




Increasingly, we notice flag states paying more attention to the SOLAS requirement for a lightship survey every 5 years. The tolerance for variation in lightship is small; should a vessel fail its lightship survey, an inclination test is required.

 In performing a lightship survey, we advise the crew on how to best prepare the vessel & meticulously survey the vessel in order to correctly estimate the weight of items which may be deducted (deadweight) combined with a survey of the vessel's draft. 



One of the more iconic real-life tests of naval architecture; a process where we test the ship's stability measurement of the heeling response of the ship to the addition of weight and the movement of weight from one side to the other.


By calculation of the heel response to a given heeling movement, we are able to calculate the position of the ship's center of gravity.



IMO regulations II-2/20 and III/9 of SOLAS and IMO resolutions A.654(16) and A.760(18) state the mandatory compliance of all ships regarding the fire control & safety plans.

 The services include:

  • Development of complete plans

  • Structural fire Protection or Means of Escape & Lifesaving 

  • Preparation of safety procedures &  tailored plans

  • Implementation of required printed material onboard

  • Printing of booklets in full color & comprehensible style

  • Submission of plans to Class & Flag for approval



The stressful situation of the need for an emergency tow can be dealt with in a safe and orderly way, by good preparation. These obligatory and personalized documents contain all the information and procedures needed in case of an emergency towing situations such as drawings of fore and aft decks mooring arrangements, strength calculation, Towing bridle design, inventory of equipment, and a communication plan listing all information that is required to be communicated during the towing operation.​

Our services include; survey, document preparation and submission to class.




Our project management skills for bespoke projects around the world are unparalleled, and trusted by companies and individuals alike.

For a presentation of our work, please get in touch.



Rules, regulations, Class Societies and Flags are our expertise.  We ensure that all of our designs are class approved, and additionally offer a complete service of ship inspection, assessment and execution of necessary procedures in order for the vessel to gain its necessary approvals.


We additionally offer ongoing management of plan approvals for exploration vessels, or shipyards & management companies.
