Oil spill a major concern from the mid-sea accident involving cargo vessel off Kochi coast
KOCHI: While the Coast Guard, Navy, and the shipping company are making efforts to salvage MSC Elsa 3 which has reported a listing of 26 to 28 degree off Kochi coast, containing the oil spill has become a bigger concern. The vessel was transporting very low-sulphur fuel oil and marine gas oil from Tuticorin to Kochi port. As a few containers have fallen into the sea, the disaster management authority has issued an alert on possible oil spill.
As the fallen containers may drift and reach the coastal areas of Kerala, an alert has been sounded and the residents of coastal areas have been cautioned against going near the containers.
According to chemical safety expert R Venugopal, who is a former joint chief controller of explosives of the Petroleum and Explosives Safety Organisation (PESO), the chances of oil spill from the fallen containers are high and the authorities should initiate steps to contain it. 'They should seek the support of oil companies for containment measures. Floating barriers or oil booms should be deployed around the spill to contain and prevent oil from spreading further. Mechanical or absorbent skimmers should be used to remove oil from the water surface efficiently. Barriers should be installed to direct oil towards clean-up zones, preventing accumulation in sensitive areas. Specialised sorbent booms, pads, and granular absorbents designed for hydrocarbon recovery can help absorb the oil spreading on the sea surface,' he said.
What is VLSFO and MGO?
Very low sulfur fuel oil (VLSFO), represents a category of marine fuel designed to meet the International Maritime Organisation's regulations that limit the sulfur content in ship fuel to 0.5% by weight. Unlike traditional heavy fuel oil (HFO), VLSFO is blended from various components, including lighter, more refined products and some heavy fuel elements, to strike a balance between sulfur content, energy content, and cost. The VLSFO is more environmentally friendly but expensive due to the refining and blending required to reduce sulfur levels.
Marine gas oil (MGO) is a marine fuel that consists solely of distillates, the components of crude oil that evaporate in fractional distillation and are then condensed from the gas phase into liquid fractions. It is similar to diesel but has a higher density, and unlike HFO, marine gas oil doesn't require heating during storage.

Fire on waters: on India and maritime accidents
The Indian coast needs to be protected against three types of major peacetime maritime accidents involving merchant ships: sinking of merchant ships, causing the loss of cargo, disruption of maritime traffic, and environmental damage; fire onboard merchant vessels that can seriously threaten not just the environment but also life and property on the coast; and oil spills. The recent fire onboard MV Wan Hai 503, that started with explosions when the ship was some 44 nautical miles off the Azhikkal coast in Kannur, Kerala, on June 9, has been successfully controlled now. Photographs of the ship showed a cocktail of smoke of brown, white, grey and black colours billowing out, indicating that many substances were burning. The cargo manifest showed that more than 140 of the 1,754 containers had various types of hazardous cargo. Coast Guard officials report that the raging Wan Hai had started drifting dangerously towards the coast even as firefighting was on and the sea remained rough under monsoon conditions. A tow rope was passed onto the ship but it snapped. An Indian Navy helicopter flew in to airdrop a salvage team and pass a wire rope that was made of steel, which was then used to tow the ship 45 nautical miles away from the coast where the depth is nearly one kilometre. The owner of the vessel pitched in by commandeering tugs through their agents. Wan Hai does not pose an immediate danger to the Indian coast now. Smoke is still seen from the ship and there are hot spots, but it is now up to the ship owner to salvage the vessel after completely putting out the fire. Most of the patrol vessels, the workhorse of the Coast Guard, are now fitted with firefighting equipment since firefighting is a key mandate of the agency. While hazardous cargo on containers are indeed a major fire hazard, a more severe fire hazard is oil. Gas-carrying merchant ships are perhaps the greatest fire and explosion hazards. Nightmare scenarios that can bring the world to its knees involve gas carrier accidents at choke points such as the Suez Canal or the Strait of Malacca off Singapore. In 2020, the Indian Coast Guard and Navy successfully put out a massive fire that broke out off Colombo on the Very Large Crude Carrier (VLCC), New Diamond, chartered by the Indian Oil Corporation. The VLCC was carrying 2,70,000 tonnes of crude oil and bound for Paradip in Odisha. That these ships were structurally intact despite week-long infernos is a testament as much to the maritime firefighting capabilities of India as the advanced design, materials and construction of the ships. Quick salvage of sunk ships and fighting oil spills, which require quick, extensive and close multi-agency coordination, are the other areas where India needs to build and demonstrate more expertise.

A sea full of troubles for Kerala
(NOTE: This article was originally published in the India Today issue dated June 23, 2025)In the span of just two weeks, Kerala's 600-kilometre shoreline—a ribbon of emerald backwaters and bustling fishing hamlets—has been rattled by two catastrophic maritime mishaps involving cargo ships, sending shockwaves through its coastal communities and unfurling environmental red first blow came on May 25, when the Liberian-flagged MSC Elsa 3, a hulking vessel carrying 643 containers, succumbed to a suspected mechanical failure and sank 14.6 nautical miles off the Thottappally coast. The ship, sailing between the Vizhinjam and Kochi ports, had 24 crew members, rescued well in time. But the real trouble lay beneath the waves: several containers of hazardous cargo, now submerged or bobbing ashore in Thiruvananthapuram, Kollam and Alappuzha. Salvage crews are still racing to prevent the ship's fuel tanks from leaking oil, but the greater menace may be the plastic nurdles—tiny, insidious pellets used in plastic manufacturing—scattered across the water, a synthetic blizzard in the middle of fish-breeding Kerala's coast was still catching its breath, the sea had other plans. On June 9, the Singapore-registered MV Wan Hai 503, a floating warehouse of 650 containers, erupted in flames and explosions further north, 43 nautical miles off the Azhikkal coast. The ship, bound from Colombo to Mumbai, had 22 crew members. Four are missing and two of the 18 rescued have severe burns. Five coast guard ships and the navy's INS Surat were deployed, but the fire, fed by volatile cargo—nitrocellulose, benzophenone, magnesium, turpentine, ethanol—proved a stubborn adversary. Adding to the peril, the vessel's 2,000 tonnes of marine oil and 240 tonnes of diesel sit precariously close to 32 tonnes of alcohol, making for a lethally inflammable cocktail. 'Our priority is to carry out salvage operations and minimise the oil spill. The task is very challenging,' says Commander Atul Pillai, defence PRO for Kerala and AFTER THE WRECKBack in Kochi, the bureaucratic machinery has lurched into motion. Chief Minister Pinarayi Vijayan has set up two high-level committees—one at the state level and another at the district level—to coordinate relief and environmental assessments. 'The state has taken all necessary precautions [to contain] maritime casualties and is conducting environmental and social impact studies on the Kerala coast,' says chief secretary A. Jayathilak. 'Now, our priority is to assess [immediate] losses and extend relief to the affected coastal communities.' The state, after some foot-dragging, has also filed a criminal case against Mediterranean Shipping Company, the Geneva-headquartered operator of the MSC Elsa 3. With the southwest monsoon back at orange alert levels and a statewide trawling ban in effect since June 10, the dual disasters have dealt a double blow to Kerala's 1.13 million-strong fishing community. 'These shipwrecks have compounded the fisherfolk's hardships,' says T.J. Anjalose, state president of the All India Trade Union Congress. 'They are finding more plastic than fish. The state must compensate them for the losses and press for a thorough investigation by the Directorate General of Shipping.'The predominantly fish-eating state is also increasingly concerned about the toxic pollution washing up along its once-pristine coastlines. Dr Anu Gopinath, head of the aquatic environment management department at Kerala University of Fisheries and Ocean Studies (KUFOS) in Kochi, has warned of serious long-term consequences. 'We must conduct detailed monitoring on the impact of the shipwrecks. The Wan Hai vessel has tonnes of inflammable and toxic substances, including pesticides, that may threaten aquatic ecosystems with far-reaching and serious consequences,' she says. The Kochi-based Central Marine Fisheries Research Institute (CMFRI), initially tasked with investigating coastal pollution after the MSC Elsa 3 wreck, has now begun collecting seawater samples near the Wan Hai mishap site as well to detect the presence of harmful chemicals. As salvage crews toil against time and tide, Kerala finds itself at an inflection point. V.J. Mathew, former chairman of the Kerala Maritime Board, argues that with the Vizhinjam port expanding, the state needs a permanent maritime monitoring system and tougher legal mechanisms. 'Shipping companies must be held accountable,' he says. The immediate crisis will fade, as all crises do. But without urgent reforms—stricter regulations and enforcement for hazardous cargo movement and long-term ecological surveillance—Kerala's fragile marine habitats, and the lives that depend on them, may be doomed to relive these disasters, again and to India Today MagazineTune InMust Watch

Family Trifecta: 3 officers in Army, Navy, IAF
Family Trifecta: 3 officers in Army, Navy, IAF DEHRADUN: In a proud moment steeped in tradition and service, a Bengaluru-based family with deep roots in India's defence services witnessed its youngest member don the Indian Army uniform at the Indian Military Academy on Saturday. The occasion marked a milestone for Indian Air Force Air Commodore Vasant Navad, currently serving at the Integrated Defence Staff in Delhi, as he watched his younger son, Anmol Navad, join the ranks of the Indian Army as a commissioned officer. Adding to the joy, Anmol's elder brother, Aryan Navad, an officer (naval aviator) in the Indian Navy , stood proudly beside him, celebrating the continuation of a family legacy dedicated to national service in all three wings of India's armed forces - Army, Navy and Air Force. "These two individuals constantly inspired me to do something meaningful for the nation - something unique and challenging," said newly commissioned Lieutenant Anmol Navad. "My father is my source of inspiration, and my brother remains a rock-solid guiding pillar. Defence is where I truly belong." Asked about the unique roles each member of his family will play in safeguarding the nation, Air Commodore Vasant Navad emphasised the critical coordination required among the three armed services to achieve victory, similar to the one during Operation Sindoor . "Modern warfare has evolved into a multi-domain operation - whether it's space, cyber or psychological warfare, success now hinges on superior information and strategic integration," he said. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo All set to join the Infantry Regiment of the Indian Army, Anmol shared his passion for squash and running - the latter, he said, gives him a true adrenaline rush. "Running pushes you beyond your limits, and that's where the sense of achievement lies. It was one of the reasons I was drawn to the National Defence Academy." Reflecting on his time at the IMA, he recalled the Bhadraj camp in the Mussoorie hills as one of the most challenging parts of his training. Anmol's maternal grandfather, a decorated officer in the Territorial Army and recipient of the President's Medal, also embodied the family's legacy of service.
