Modernization

Mazagon Dock Shipbuilders Limited (MDL) had successfully completed the augmentation of their infrastructure through Mazdock Modernisation Project (MMP) which comprises of a new Wet Basin, a Heavy Duty Goliath Crane, a Module Workshop, a Cradle Assembly Shop, Store Building and associated ancillary structures.

MDL is aiming at a paradigm shift in warship and submarine construction enabling integrated modular construction thereby reducing the construction period. Post-modernisation, MDL capacity for shipbuilding has increased from 8 warships to 10 warships since 2014 and submarine capacity has increased from 6 submarines to 11 submarines since 2016.

Kanhoji-Angre Wet Basin:

The new Wet basin equipped with 4 Level Luffing Cranes is a Civil Engineering marvel constructed in a marine environment offering 27000 square meter of berthing space to accommodate two large frigates and two submarines for outfitting which adds to MDL’s self sufficiency of its berthing needs.

Module Workshop:

Module shop having an area of approx. 6000 sqm with two 50 tons EOT crane and retractable roof is designed for the fabrication of larger hull blocks, substantially pre-outfitted within a covered environment, wherein level of completion of outfitting in shop would be increased resulting in considerably reduced build period, improved quality together with better working environment for the operatives.

Goliath crane:

The Heavy Duty Goliath crane is having a lifting capacity of 300 T and is straddling across two slipways and the module shop with a span of 138m. The crane is equipped with future that enables overturning of modules to undertake construction of large ship block and thereby reducing build period considerably.

Cradle Assembly Shop:

The Cradle Assembly Shop (CAS) along with Store Building has been constructed as part of construction program of submarines. The CAS is primarily being used for fabrication and pre outfitting of cradle structure in unit block assemblies. A store building with provision for automatic retrieval system and storage facility for sensitive sophisticated components under controlled environment is also annexed to the CAS.

A store building with provision for automatic retrieval system and storage facility for sensitive sophisticated components under controlled environment is also annexed to the CAS.

SSA Workshop:

The submarine-building capacity has been further enhanced by construction of additional Submarine Section Assembly Workshop (SSA) of 9,900 square meter. The workshop comprises of two bays, equipped with EOT Cranes (30T) as well as semi goliath cranes, which will facilitate fabrication as well as assembly of submarine units simultaneously. There is Blasting & Painting Chamber inside the Workshop to facilitate cleaning, blasting & painting of the Submarine Sections. The workshop is operational since 2016.

Shore Integration facility (SIF):

Shore Integration Facilities (SIF) have been created for Shipbuilding and Submarine Divisions separately for Integration and simulation of various equipment and systems prior fitment onboard. The actual equipment, cables and connectors are used in SIF to keep alive critical electronic components. This unique facility will enable reduction in build period of warships and substantially reduces the testing time of submarine.

Product Lifecycle Management (PLM):

MDL is implementing PDM/PLM system for the ongoing stealth frigate programme. PDM/PLM will serve as an information management system to foster seamless collaboration between various disciplines associated with the production of the ship including planning, design, production, procurement, maintenance and Quality Assurance. It is a platform for data management and is being developed at MDL, IHQ and GRSE in consultation with M/s Siemens. The PLM system, introduced for the first time in project 17A will result in a digital transformation of naval shipbuilding. PDM/PLM will also improve level of integration and accuracy of forecasting. It enables the yard to develop and maintain a digital replica of the ships and makes the data accessible to the various agencies involved in the entire lifecycle of the ships.

Virtual Reality Lab (VRL):

A State –of-the-art virtual Reality Lab has been commissioned at MDL Design Dept. Virtual reality (VR) is a scientific and technical tool which uses computer graphics and behavioural interfaces which simulates a virtual universe by the use of a graphical, sometimes audio, presentation in a space fitted with multiple and/or large dimension screens. The user interacts with the entities of the virtual universe.

The lab enables the designers arrive at optimal layouts of highly congested compartments in a virtually immersed environment. Successful adaption of Virtual reality for reviewing the detail design of P15B Ships in a virtual environment has resulted in optimal layouts, overall enhancement of ergonomics and Human factor engineering (HFE) from the user’s perspective, an exponential reduction in time and cost from the builder’s perspective and a drastic reduction in on-site inspection effort by the Navy’s overseeing team.

Implementation of ERP:

SAP – ERP is used as business application in MDL. The SAP system of MDL consisted of number of fully integrated modules which covers virtually every aspect of the business management. Implementation of SAP has helped MDL to strengthen the internal control systems with in-built checks and balances at various levels of operations. MDL also has a Disaster Recovery site at Bengaluru for SAP.

Implementation of File Lifecycle Management (FLM):

FLM module of SAP has been implemented in MDL for approval of files in digitized form. Files for approval are processed online using workflow of FLM. On completion of workflow, system acts as a central repository for storage of approvals for long period of time with access based on User authorization.
