ROLE OF A DESIGNERROLE OF A DESIGNERThe role of a designer is to make an innovative design which is:

Environmentally friendly

Ensures safety of the crew

Utilizes modern material

ROLE OF A DESIGNERROLE OF A DESIGNERComplies with…

Classification rules

National and international rules and regulations

ROLE OF A DESIGNERROLE OF A DESIGNERWhile optimizing…

Ship Owners and Charterers commercial needs

Shipyard’s construction cost and time

A designer’s role should not be limited to basic and class drawings, but should also extend to production drawings.

INNOVATIVE DESIGNINNOVATIVE DESIGNSuccess of a good design largely decides the success of any ship – whether it is at the building stage or while it is in service.

Factors that affect a design:Education of designersExperience of designersExtent of research and market analysis

INNOVATIVE DESIGNINNOVATIVE DESIGN Constant communication between

designer and:Shipyard

Shipowner

Charterer

Technical Managers

Classification Societies

INNOVATIVE DESIGNINNOVATIVE DESIGN Constant communication between

designer and:Regulatory bodies

Machinery/equipment manufacturers

Specialists in subjects like structure, hydrodynamics, propulsion, etc.

INNOVATIVE DESIGNINNOVATIVE DESIGN Use of software for development of

optimized design and for quality control

Application of latest technical innovations like computational fluid dynamics, finite element analysis, dynamic load analysis etc

Application of Goal based new ship construction standards

ENVIRONMENT ENVIRONMENT FRIENDLYFRIENDLY Use of

double bottom and double hull environment friendly materials recyclable materials

Redundancy in propulsion and navigation in emergency situations

Protection of Fuel oils tanks by double hull and double bottom

ENVIRONMENTALLY ENVIRONMENTALLY FRIENDLYFRIENDLY

Arrangement for treatment and safe disposal of sewage, garbage, noxious liquid, and oil sludge

Treatment and management of ballast water

Prevention of air pollution

Use of anti-fouling system without organotin compounds acting as biocide

CREW SAFETYCREW SAFETY Alleviate crew fatigue

Sensible / logical and ergonomic layout of engine room, control room, wheel house and other working spaces

Thoughtful location of machinery and equipment with convenience of servicing, maintenance and repair in mind.

CREW SAFETYCREW SAFETY Ensure crew mental & physical well

beingReflect comfort of the crew in

Accommodation, Recreational and Communication facilities

NEED FOR INDEPENDENCENEED FOR INDEPENDENCE Production of a balanced design requires

integration of complex and conflicting demands of Ship Owner, Shipbuilder, Charterer, Operator and regulatory bodies

Builder developed design will be favorable to the builder

Independence of designer is required to produce a balanced and good design

Ship Owner support required for promoting independent design house

CONSTRAINTS IN CONSTRAINTS IN PRODUCING A GOOD DESIGNPRODUCING A GOOD DESIGNIn the current market a designer faces mainly THREE types of constraints…

TECHNICALCOMMERCIALTIME

TECHNICALTECHNICAL Lack of information from Owners and Charterers

Designers working in isolation from Owners and Charterers

Owners not planning sufficiently regarding their requirements

Lack of recognition of Designer’s role by Owners Unwillingness to support the role of designers leads

to cutting down of design expenditure resulting in loss of quality

TECHNICALTECHNICAL Lack of communication between design

firms and shipyards

Designers unable to adapt the production design to suit shipyard need because they are not onsite to assess the particular yard’s requirements

Designers not directly involved in the construction process therefore can not envisage glitches

Production design problem. TECHNICALTECHNICAL

TECHNICALTECHNICALProduction design problem.

TECHNICALTECHNICAL Lack of skilled personnel

Traditionally low remuneration combined with long working hours

Sudden boom in shipbuilding making demand greater than supply

Use of cheaper software technicians who blindly copy than use of designers with computer knowledge

TECHNICALTECHNICALUseUse of cheaper software technicians who of cheaper software technicians who

blindly copyblindly copy : GRP Pipe i.w.o. Erection Joint.

TECHNICALTECHNICALProduction design problem: GRP Pipe i.w.o. Erection Joint. Pipes to be inserted after erecting the blocks Block erection to be slowed for insertion of pipe Working access to erection joint is limited from fit-up,

welding and painting point of view GRP Pipes installation can not commence unless welding

and painting works are completed GRP Pipes are vulnerable to damage from hot work in

way of erection joint

Data: LR Fairplay

TECHNICALTECHNICAL Lack of feedback after design is

delivered Industry practice of not communicating

with designer

Lack of Knowledge BaseUnwillingness to spend on research

because of uncertainty of recovering costs due to traditionally low margins

TECHNICALTECHNICAL

Lack of internal review of design work

Lack of standardization and proper documentation of proven design

COMMERCIALCOMMERCIALInadequate compensationRatio of compensation to man hours is relatively low

Only 1-2% of a ship’s price is allocated for design

Owners’ reluctance to invest for additional quality due to Market’s unwillingness to discern – exception being Oil majors and a few selected Ship Owners and Charterers

COMMERCIALCOMMERCIAL

Non existence of unified rules & varying standards among classification societies

Lack of independence of Classification Societies from Owners and Shipbuilders and the need to compete with each other reducing effectiveness in controlling standards

COMMERCIALCOMMERCIAL Inability to benefit from economies of

scaleGain from repeated production of same

design is reduced due to necessity of making fresh drawings resulting from:

Differing crane capacities and ensuing block lifting abilities from shipyard to shipyard

Need for varying steel plate sizes depending on shipyard production facility and non availability of tailor made steel plates

COMMERCIALCOMMERCIAL Violation of intellectual property

rightsLack of recourse against flagrant and rampant copying of designs dampening incentive for research and innovation

Lack of skilled personnel at Shipyard

Shortage of qualified production design staff at shipyards - increasing cost due to rework and reducing quality

TIMETIME Need to produce designs at a rapid pace

Traditionally low margins preventing investment in designs until firm orders are in place

Ships are acquired on ad-hoc basis based on existing market condition than planned fleet expansion

Shipyards: mainly for start up yards and yards with no orders: inability to wait for design to be completed before commencement of production - leading to tight deadlines
