Mumbai High (formerly Bombay High) is India’s largest offshore oil and gas field located in the Arabian sea approximately 160km off the Mumbai coast.  

A total of thirteen platforms and 28 rigs operate in this region, served by approximately 70 supply vessels. The field has been operated by the Oil and Natural Gas Corporation (ONGC) since 1976 and produces around 12MMT per year. The ONGC was the only Indian Energy major to be listed in Fortune’s Most Admired List 2012 under the ‘Mining, Crude Oil Production’ category.

The Nhava Supply Base (NSB) is a Custom Notified Marine Port of ONGC that is situated on the Eastern edge of Jawaharlal Nehru Container Terminal (JNPT). The supply base was commissioned in 1983 and is the sole port handling supplies to the Mumbai High offshore operations. The total area of the supply base is approximately 60ha which includes storage, warehousing, pipe yards and offices. It has a total of 350m quay length and can handle simultaneous loading and unloading of up to five vessels at any one time.

A number of factors made it clear that the NSB was in need of an upgrade, including conventional handling methods at the waterfront, limited storage units and poor maintenance. The objective of the ONGC was to develop the base in line with international standards, enabling it to offer best-in-class facilities for efficient supply chain management through improved warehousing and handling of materials. 

Royal HaskoningDHV was appointed in 2012 to develop a complete masterplan for the entire supply base, including both waterfront and shore-side facilities. In order to meet this brief, we conducted a number of meetings with key people, as well as site visits in order to gain a full understanding of the situation and its requirements. 

The primary aim within the masterplan at ground level was to reduce the turnaround time of supply vessels alongside key safety standards. The completed masterplan therefore focused on incorporating international standards such as ISO and DNV in areas such as warehousing and open areas. Modern storage methods such as high bay pallet racking system with mechanised palletisers were proposed for effective usage of space. Making better use of the existing waterfront structure was also identified as a priority, with a range of option offered to the client including straightening of the quayside and new ways of berthing port crafts.
