Shipbuilding & Shiprepair – A Comparison
3www.mantrana.in
Shipbuilding
• Shipbuilding is Like a Marathon race
• Long Lead Time
• Long Delivery Schedule
• Tasks can be automated, standardized
• Work schedule is planned and
deliberate
• Scope of Changes minimal
• Incase of deviation, enough time to
implement
Shiprepair
• Shiprepair is like 100 m sprint race
• High turnaround
• Difficult to estimate work content
• Time schedule
• Project budget
• Hidden work emerges during execution
• Has to work with pre defined conditions
• Degree of Specialization is very high
• Work contract ought to change as repair
work progresses

Types of Shiprepair
6www.mantrana.in
• Voyage Repair – Its an ongoing activity carried out by ships crew
• Annual Survey – It’s a floating repair, more like Shave – Shampoo activity
carried before annual survey. Its carried out in port of call
• Dry-docking – Twice every five year, Its an extensive repair of underwater
Hull, Overhauling of Equipments and Machinery. It requires steel renewals,
major refits. Its carried out in a Shipyard using Drydock/ Slipways/ Shiplift
facility. Requires all faculty of Project Management, involved with several
uncertainties
• Damage Repair- This is done aftermath of a collision/ grounding/ or any
other type of accident. The Shipyard gets to inspect the ship, before
bidding for project.

Dry Docking Shiprepair - Tender
7www.mantrana.in
Dry-docking Project Starts with Ambiguities
• Date of Tender : November 6th, 2009
• Submission of Bid : December 2nd, 2009
• Type of Ship : Crude Carrier (VLCC)
• Content of Enquiry: “Informatively, the vessel is expected to be released for
dry-docking at India/Japan Range around End December, 2009 / January 2010.
Accordingly, we expect to receive tenders only from our empanelled shipyards
located in above mentioned area/route to reduce incidental positioning
cost/time and suit our commercial requirements.”
• ……….the enquiry is followed by tasks to be performed during dry docking
• Document would also have a clause “ all tasks essential but not mentioned
above”

Project Management
12www.mantrana.in
• Definition : Planning, directing, and controlling resources to meet the desired
objectives, which are in the present case
• Timely Completion
• Meet Quality Standards
• Meet Budgeted Cost
• Avoid wastage of Resources
• Divide the Project into Tasks, Subtasks; Work Break Down Structure. i.e.
• Subdivision based on function
• Subdivision based on zones
• Identify the Critical Path
• Longest time consuming path
• Alternatively the shortest time to complete a task
• Monitor and Review all the tasks, subtasks at periodic intervals
• Take Corrective measures, incase of slippage in timelines

• Offshore Supply Vessels, tend to get repaired locally
• Offshore Rigs – travel far off for repair due unavailability of local competence

• Theoretically both the methods would
provide similar critical path
• Depending upon Ship type, actual result
vary
• Subdivision based on Zones is better for
Offshore Supply Vessels
• Subdivision based on Function – Better
for Cargo Vessels

Implied Responsibility of Project Manager - Shiprepair
27www.mantrana.in
• Plan & Budget for Time & Cost for jobs Mentioned in Contract
• Plan & Budget for Time & Cost for jobs Not Mentioned in Contract
i.e. Implied jobs
If the tender document requires steel renewal in the engine room.
Work content to be budgeted for is
Main Task :- Renew Steel in Engine Room
Implied Task: -
1. Insulation in the Engine Room to be removed
2. Cable Trays, Piping in the region to be dismantled if required and refitted
3. Entire Insulation, Cladding and Fitment Panel to be done
4. If steel renewal falls between say engine girders, welding would require
additional man-days

Implied Responsibility of Project Manager - Shiprepair
28www.mantrana.in
• As fitted drawings with structural items may not provide exact fittings on ship
• Project Manager is required to carryout extensive survey on arrival of vessel
• List down deviation from the bidding scope & actual work found during
inspection
• Re-work & arrive on reasonable estimate of Man-hour
• Constitutes close to 60% of the cost of repair
• Work with owner on the deviation in bid and actual work content
• Pursue owner to increase project fee
