COMACOE is pleased to announce the receipt of award for Sea water Filtration and Intake System from Indian Oil Corporation Ltd. (IOCL) for LPG Import Terminal, Paradip

IOCL has constructed LPG Marketing Terminal at Paradip, Orissa in order to store and distribute LPG production of IOCL Refinery at Paradip. Now, IOCL is planning to set up new LPG import terminal within the above set-up Marketing Terminal premises. In order to meet the requirements, IOCL is also planning to install two Marine loading arms at South Oil jetty, to take Propane & Butane from Ship.

Each consignment of refrigerated liquid propane at -42°C and Butane at -4°C is planned to be unloaded from VLGC ship (45000 MT capacities) at a rate of 1200 MT/hr (max.) with the help of two numbers of marine unloading arms on south oil jetty & booster pumps located adjacent to Jetty area. The refrigerated Propane & Butane is planned to be heated to 5°C by sea water in shell and tube exchangers. Thereafter, heated Propane and Butane is planned to be transferred to mounded storage bullets located at terminal through two 16” cross country underground pipelines. This project is to build the required Sea Water Intake and Filteration system to provide the seawater required for heating the refrigerated product. The scope includes detailed engineering, procurement and supply of materials and consumables and mandatory spares, fabrication, erection, testing, insulation, making new hook-up/tie-in connections with existing facilities.

Brief scope of work includes:

• 4 x Intake Caissons of 20 meters height each
• Super Duplex VT pumps (800 m³/hr)
• Coarse and Fine (100µ) filters
• HDPE & GRP Piping (750 NB)
• Dredging & Backfilling
• PEB Civil structures
• Intake Screens of 3000µ
• Control and Instrumentation

Projects & Development India Limited (PDIL) are the owner’s consultants for the Project.

COMACOE is proud to announce the receipt of award of SWIO system from BARC for desalination system at Gopalpur, Odisha.

Bhabha Atomic Research Centre (BARC) is setting up a 5.0 MLD hybrid sea water desalination plant comprising of 4.5 MLD sea water reverse osmosis (SWRO) system and 0.5 MLD multi-effect distillation (MED) system within the existing premises at Orissa Sands Complex (OSCOM), Indian Rare Earths Limited (IREL), Matikhalo, Dist: Ganjam, Odisha.

The Desalination plant requires sea water at the rate of about 1000 cu.m/hr (i.e 24 MLD) to be drawn from Bay of Bengal and will discharge reject brine of about 800 cu.m/hr to the sea.

In a competitive bidding process, COMACOE was declared to the successful bidder and awarded the contract on EPC basis.

Sea water is planned to be drawn from a distance of about 900 meter in the open sea where a cupronickel intake filter is located at a depth of 11.4 meter below chart datum (CD) / at – 12.9 m from mean sea level (MSL).The seawater flows through buried 900 mm DN (O.D) HDPE, PE 100, PN8 pipeline, with at least 1.5 m cover over the anchor block. The HDPE main conveyance line and 4 nos. of 63 mm DN (O.D) composite HDPE/Aluminium pipes are to installed external to the main conveyance pipeline with proper supports and anchorage. The offshore intake pipeline is connected  to  900 mm O.D pipe header through manual operated gate valve. The raw seawater flows into six nos.  of basket filters where seawater is coarse filtered. The filtered seawater enters suction of four nos. (3 working+1 standby) of horizontal split casing centrifugal pumps through a 900 mm OD header. The pumps supply seawater to desalination plant facility site through buried 630 mm O.D HDPE line of PN 10 rating. Reject Disposal System consists of Reject water tank & Brine disposal pumps at Desalination plant facility site and thereafter, buried single onshore pipeline & submarine pipeline up (PN 10) to offshore multiport diffuser at 800 meter inside the sea where water depth is 12.1 meter & 270 meters away from the offshore intake point.

Brief scope of work includes:

• 1 x 975m intake line 900mm dia
• RCC caisson intake well depth of approx. -11.5m
• 1 x 875m outfall line 500mm dia with Multi port diffusers
• Air bursting system
• Chlorination system
• Construction of pump house including all civil, electromechanical and E&I work

COMACOE is very proud to announce the receipt of award of 3 projects from NIOT for setting up LTTD (low Temperature Thermal Desalination) Plants at islands of Kadamat, Amini and Chetlet at Lakshadweep islands.

The Lakshadweep islands have an acute shortage of potable water and mostly survives on supplies from mainland. Over the past 15 years, Government has struggled to develop some reasonable solution to resolve this water crisis in the islands and after successful experiments with Low Temperature Thermal Desalination (LTTD) Plants in 3 islands (Kavaratti in 2005, Minicoy and Agatti in 2011) by NIOT, it was decided to go ahead and setup such LTTD plants in 6 islands namely, Amini, Chetlet, Kadamath, Kalpeni, Kiltan and Androth with capacity to produce approx 165,000 litres of potable water per day from sea water.

Accordingly, E-tenders (6 separate tenders) were invited by NIOT for the above 6 mentioned islands in September 2017 and LoAs were issued for 5 islands in March 2018. COMACOE bid for 4 islands and has been awarded 3 – namely, Kadamat, Amini and Chetlet.

The Contracts were signed on April 6th at Prithvi Bhavan, Delhi by NIOT Director, Dr. M.A.Atmanand and COMACOE CEO, Mr. Vivek Bansal in presence of Dr. Madhavan Nair Rajeevan (Chair, Earth System Science Organization (ESSO) and Secretary to the Government of India for Ministry of Earth Sciences (MoES), COMACOE Founder & MD, Mr. Sanjeev Rai, and other NIOT stakeholders – Dr. MV Ramanamurthy, Dr. SVS Phani Kumar and others.

The proposed desalination plants will run on the principle of Low Temperature Thermal Desalination (LTTD) that involves evaporating warm surface seawater (at about 28 degC) in a Flash Chamber maintained under Vacuum (at about 27 mbar) and consequently liquefying the resulting vapour in a Condenser. The coolant water for the condenser is drawn using the thermal gradient available in the ocean, namely using the feature of reduction of ocean water temperature with an increase in depth. A long pipe is deployed in the ocean to draw the cold water (at about 12 degC) from a distance of about 1000m from a depth of about 350-400m.

National Institute of Ocean Technology (NIOT), an autonomous body under the Ministry of Earth Sciences, and is engaged in developing technology for utilizing ocean resources in an eco-friendly manner.
