NEWCON Survey Vessels

Ministry of Defence has awarded contract for design, construction and supply of four Survey Vessels for Indian Navy to Garden Reach Shipbuilders & Engineers (GRSE) Limited, Kolkata after it became successful bidder in the competitive bidding. The contract was signed between Ministry of Defence and GRSE 31 October 2018. GRSEs bid of Rs 520 crore for each vessel bettered L&Ts quote of Rs 742 crore, which was almost 43% higher. The other shipyards who had responded to the RFP in 2015 were Hindustan Shipyard Rs 563 crore per vessel, Goa Shipyard Rs 568 crore, Cochin Shipyard Rs 573 crore and Shoft Shipyard Rs 670 crore.

The contract was signed by Joint Secretary & Acquisition Manager (MS) Shri Ravi Kant on behalf of the Ministry and Director(Shipbuilding)Cmde S Nayyar IN (Retd) for GRSE, Kolkata. Request for Proposal was issued by Indian Navy to four PSU shipyards viz. GRSE, Goa Shipyard Limited (GSL), Hindustan Shipyard Limited (HSL), Cochin Shipyard Limited (CSL) and two Indian Private Shipyards in April 2016, with GRSE emerging as the lowest & successful bidder. The order value for these four vessels is Rs. 2435.15 crore. The first ship is to be delivered within 36 months and remaining within an interval of six months for each vessel. The project completion time is 54 months from date of signing the contract. With this prestigious contract, GRSEs Order Book as on date stands at Rs. 22,604 crore. The GRSE is currently handling a major project to make three Stealth Frigates for Indian Navy under P17A Project.

The defence PSU has been a pioneer warship builder of the nation having delivered the highest number of warships till date since its inception in 1960. The 98 warships built by GRSE so far range from Advanced Frigates to Anti-Submarine Warfare Corvettes to Fleet Tankers, Fast Attack Crafts, etc. with the Shipyard having many firsts to its credit in terms of Innovation and Design. It has already delivered six Sandhayak Class Survey Vessels to Indian Navy between the period February 1981 to February 1993. The present project will further consolidate GRSEs position as a unique shipyard with all round capability to design and build Survey Vessels with state-of-the-art technology.

These Survey Vessels (Large) shall be 110 metre long with deep displacement of 3,300 tonnes and complement of 231, capable of fullscale coastal and deep-water hydrographic survey of ports and harbours, approaches and determination of navigational channels/routes. In addition, the vessels shall undertake surveys of maritime limits up to EEZ/extended continental shelf. These shall be deployed for collection of oceanographic and geophysical data for defence applications. In their secondary role, these shall be capable of performing limited search & rescue, limited ocean research and operate as hospital ship/casualty holding ships.

The vessels are equipped with highly advanced state-of-the-art hydrographic equipment & sensors including a Hello Hanger to accommodate one Advanced Light Helicopter. The design and construction of these ships by GRSE will truly signify Make in India initiative of the Government. Vessels will be built as per Classification Society Rules and Naval Ship Regulations and will conform to latest MARPOL (Marine Pollution) Standards of the International Maritime Organisation (IMO).

The Survey Vessels would be deployed for coastal/ deep-water hydrographic and oceanographic surveys by the hydrographic department of the Indian Navy. The Primary Role is full scale coastal and deep-water Hydrographic Survey capability of Ports and Harbours, Approaches and determination of Navigational channels/routes. In addition, surveys of maritime limits up to EEZ / extended continental shelf. Conduct of limited oceanographic surveys for defence applications.

Secondary Roles are to perform limited defence role in an emergency [suitable arrangements for installation of One 30 mm Naval Surface Gun (NSG) with Electro Optical Fire Control System (EOFCS) or as indicated by Indian Navy]. Limited search and rescue capability and Hospital ship/casualty holding Ship.

The ships should be built as per Classification society rules and regulations for the construction and classification of naval ships with an expected life of 35 years. The should adhere to latest MARPOL standards of pollution control. All machinery, sensors and equipment should have maximum reliability and maintainability for a mission time of eight weeks at a stretch.

The propulsion system should consist of twin-shaft arrangement, each shaft driven by one Marine Engine driving a FPP/ CPP through a reversible reduction gearbox. Auxiliary Propulsion consisting of Stern Thrusters is to be provided to cater for prolonged slow speed operation of the vessel to avoid under loading of main diesel engines and enable better manoeuvrability. Bow Thrusters are to be provided. The propulsion machinery is to be designed to meet the specified operating profile of the ship as specified. The ship is to be provided with active stabiliser system to ensure optimum utilisation of weapons, sensors, aviation facilities as well as operational and habitability criteria of the ship along with reduction of the heavy rolling of the ship.

The Survey Motor Boat (SMB), in hydrographic surveying, is employed for collecting bathymetric, oceanographic and geo-physical data in open sea / ocean, near shore waters, creeks and in rivers. In addition, the SMB would also be employed for transfer of personnel, stores and equipment ashore by beaching. Two Survey Motor Boats (SMBs) of approx length 11.0 m and two SMBs of approx. length 9.0 m. All four SMBs to be hoisted by a suitably located Centreline Crane with a provision of stowage on the deck. The crane should be telescopic / retractable with a minimum outreach of 5m beyond the ship side. The Safe Working Load (SWL) of the centreline crane for lowering and hoisting of SMBs should be at least 10 tonnes at maximum outreach. Two 7.3m RIB as Sea Boat with its own single-arm davit for hoisting/lowering capable of being hoisted and lowered at slow speeds and reconfigurable for Low Intensity Maritime Operation (LIMO) role with provision for fitting LMG/MMG.

The shipbuilder is required to design and build the ship in accordance with the broad specifications of the Navy. Further, details of Survey Vessels that have been designed /built by the shipyard, if any, are also to be forwarded along with technical and operational specifications, including maximum speeds achieved, of the vessels. The design should be contemporary, meet International Standards and should have due approval of Classification Society. The relevant Class Notation is also to be provided. Suggestions/comments for building the ship to any Classification Society rules and the advantages thereof may also be indicated. All requisite design details, model testing, timelines date, relevant calculations etc will be vetted by IHQ MoD (Navy). Vendor may also utilise this opportunity to recommend capabilities proposed in terms of equipment parameters and essential parameters is in accordance with para 10 of Chapter II of DPP-2016 as input for Staff Qualitative Requirements (SQRs).

The indigenous construction must be undertaken employing contemporary technique allowing for integrated construction to derive benefits of high degree of pre- outfitting at block level. IHQ MoD (Navy) will provide a preferred list of vendors from whom the major equipment is to be sourced for the Survey Vessel. The Shipbuilder may guide the equipment supplier to configure/modularise their equipment and systems to suit integrated, preoutfitted construction and also to allow for easier upgrades and faster replacement/ repair while in service.
