Study the vessel design

Gather the as-built data –

◦ Available updated drawings

◦ 3-D Scanning

Vessel Study & Data Gathering


- For Equipment & PIPING

Single skid installation OR

Multi Location Installation

Deciding Factors – availability of space installation accessibility Minimum modifications (structural, piping, electrical)



Machinery Spaces• Access for maintenance• Additional ventilation for storage of chemicals

Pump Room• Explosion proof systems

Exposed Deck• Explosion proof systems in case of tankers• Increase in GT if enclosed compartment

added New Structural Void tanks



Modification of P&ID Pipe Routing (3D Model)◦ Minimizing pressure loss

Pipe pre fabrication drawings Bill of material Pipe Installation Drawings

Piping Design


Load Calculation Modified 1-Line Diagram Cable ducts routings & penetrations Cable Installation Drawings

Electrical Design


In Situ pipe fabrication & installation◦ Less engineering required◦ High chances of rework for clash removals◦ High Wastage of material & time◦ High down time for ship

Manual measurement onboard, 3D Routing & pre-fab◦ Less down time of ship◦ Pipes fabricated at workshop – good quality◦ Large amount of engineering time spent onboard for measurement

3D Laser Scan, 3D Routing & pre-fab◦ Less time spent onboard

Methodology


At docking/Quay side◦ Ship off-hire for the period of retrofit◦ Must in case of in situ fabrication (hot work) & installation

During sailing/operation◦ Pipe can be pre-fabricated using Pre-fabrication drawings from 3D model◦ Installation can be done during operation (cold fitting) with least

interference in normal operation

Execution


Class Approvals◦ Approvals for Retrofit Drawings◦ Coordination for Class survey onboard

Workshop Coordination◦ Technical Specification for retrofit◦ Job work order & Workshop Selection

Supervision◦ Quality inspections (critical for in-situ fabrication)◦ Workshop inspections for pre-fab pipes

Commissioning

Project Management


5500 DWT MPC◦ Length O.A – 104.000◦ Length B.P - 98.535◦ Breadth - 15.250◦ Depth - 7.450◦ Draft - 5.600

Ballast capacity – 2250 CuM Ballast pumps – 150 CuM/hr @ 2.5Bar

BWMT - PureBallast 2.0, Alfa Laval


Location - Engine Room◦ Being MPC Only space available is ER


Location - Engine Room◦ Unavailability of space in Tank Top◦ Additional Mezzanine Platform Created


Design Deliverables :

◦ Piping – Modified P&ID (Class Approved) Pre-Fabrication drawings Installation Drawings

◦ Platform Fabrication Drawings

◦ ER arrangement plan (Modified)

◦ Updated Electrical 1-line Diagram


Feasibility & Costing

◦ 32,000 Bulk Carrier◦ Ballast Pumps - 2x700 CuM/hr Pumps, ◦ Ballast Capacity - Total 12,000 CuM◦ Equipment with different treatment methods

analysed◦ Capex ranges from approx 800,000 To 1.3M USD◦ Annual Expense ranges from 7,000 To 25,000 USD


Total 60,000 Ships required to be retrofitted in a short period of time.

All existing ships must start retrofitting by 2015.

The price of equipment have drastically reduced in last two years. However, this may see reverse trend post ratification.

Sudden Demand for retrofits :◦ Equipment - High Cost / High Lead time / Non Availability ◦ Long Class approval Time◦ Premium Engineering Hrs
