Oil slick from MSC Elsa 3 continues to pose threat to marine ecosystem

The prospect of oil spill from the container vessel MSC Elsa 3, operated by Mediterranean Shipping Company (MSC), which sank off the Kochi coast on the night of May 24 while en route from Vizhinjam to Kochi, continues to be a threat to the marine ecosystem as the plan for extracting oil from the ship remains uncertain.
'We observed, with the help of satellite images, that the oil slick from the ship measured approximately 9.3 km long in the sea with a visible silver/metallic reflection on June 1, and by June 9, the slick still had a length of about 2.3 km,' according to Avinash Chanchal, Deputy Program Director, Greenpeace South Asia.
According to the latest report submitted by the Directorate General of Shipping (DGS), though significant progress has been made in capping the fuel oil tanks and stabilising the wreckage, the critical oil extraction phase is pending and is dependent on weather conditions. Any further delay could push the extraction timeline dangerously close to the peak monsoon season, increasing environmental risks and limiting salvage windows.
The salvage operations have been going on under the supervision of the DGS, with coordination involving agencies including the Indian Coast Guard, State Disaster Management Authorities, shipowners, salvors, and other stakeholders. The salvors have submitted an updated oil recovery plan from the ship with an estimated time of around 24–26 days, which too is subject to weather conditions.
The offshore weather continues to present challenges. As per the latest weather forecast dated June 15, winds of 20-25 knots from the southwest persist over the southeast Arabian Sea, with poor visibility over the next 3–5 days. The DGS has directed the salvors to submit both optimistic and realistic deadlines accounting for prevailing monsoon conditions.
According to environmentalists, the shipping company must comply with its obligation to urgently remove the remainder of the oil left in the MSC Elsa 3 tanks — out of over 450 tonnes — to avoid further damage to the region's unique marine environment and local economy. Besides, actual damage to ecosystems and local livelihoods must be duly compensated by the MSC.
The Kerala State Disaster Management Authority (KSDMA) made clear that the oil slick from the ship has been capped successfully recently by the salvors, other than minor leaks. However, the dedicated oil extraction from the ship could be completed in July, considering the prevailing weather conditions, said KSDMA sources.

Second ship sinking off Kerala coast revives fears in Sri lanka of worst maritime disaster

Sri Lanka is once again facing a significant marine environmental crisis, as tiny plastic pellets, commonly known as nurdles, have begun washing ashore along the island's northern coastline. This time, the pollution is linked to the sinking of the Liberia-flagged container ship MSC ELSA 3 off of Kerala, India. The unfolding incident has triggered fears of a repeat of the X-Press Pearl disaster in 2021, the worst maritime disaster to have occurred in Sri Lanka, significantly impacting marine ecosystems and coastal communities. According to the Indian Coast Guard, the MSC ELSA 3, carrying 640 containers including hazardous cargo, sank on May 25, roughly 38 nautical miles off the Kerala coast. The cause was reportedly a failure of its ballast system. Indian authorities confirmed the vessel was loaded with an estimated 85 metric tonnes of diesel and 367 metric tonnes of furnace oil, in addition to at least 13 containers of dangerous substances such as calcium carbide. All 24 crew members were safely rescued by Indian Coast Guard and Navy teams. While Indian authorities were able to initially contain an oil spill, the environmental fallout soon escalated. Plastic nurdles released from sunken containers began appearing on beaches in southern India, and by June 11, ocean currents driven by strong gusts of southwest monsoon winds carried them toward Sri Lanka's northern shores, raising serious concerns among marine biologists and local communities. Fresh environmental fallout 'We've begun cleaning efforts and are evaluating coordinated response actions,' said Padma Abeykoon, additional secretary at the Ministry of Environment. With strong monsoon winds forecast for the coming days, she noted that ocean currents may bring even more pollutants ashore. According to Abeykoon, Indian authorities had alerted Sri Lanka about the possibility of debris from the sunken vessel drifting toward its shores, depending on ocean current patterns. The plastic pellets first arrived on the northern islands and reached the Mannar coast within a day, continuously washing up along Sri Lanka's southern-facing beaches. One of the earliest reports from Sri Lanka came from Lahiru Walpita, a birdwatcher in Mannar, who observed the nurdles during his routine early morning seabird monitoring. 'On June 12, I noticed strange white pebbles scattered across the Mannar beach. A closer look revealed they were plastic nurdles, something I sadly recognise from the X-Press Pearl spill,' Walpita said. Walpita initially assumed the rough seas had opened up a remnant of X-Press Pearl, but as he discovered 20 25-kg bags of nurdles strewn across a 2-km stretch of the beach in Mannar, he realised something was wrong. Out of these, only two bags were damaged, and others were in perfect shape, Walpita told Mongabay. Walpita also observed crows and an egret investigating the pellets but hadn't consumed them. 'However, seabirds, like little terns and bridled terns, feed off the ocean surface while in flight and I fear they could mistake these pellets for food as they have little time to observe,' he warned. The breeding season for these species, especially on tiny islands nearby in Adam's Bridge Marine National Park, runs from May to September, and Walpita fears the nurdle invasion could disrupt their reproductive cycles. Temporary ban Meanwhile, Indian authorities imposed a temporary fishing ban within 20 nautical miles of the MSC ELSA 3 wreck to mitigate risks from hazardous cargo. One of the most concerning chemicals on board was calcium carbide, which reacts violently with water to release acetylene – a highly flammable and potentially explosive gas – and produces caustic substances harmful to marine life. 'The ship sank about 300 nautical miles from Sri Lanka, so we don't anticipate immediate chemical contamination threat for Sri Lankan waters,' said Jagath Gunasekara, general manager of Sri Lanka's Marine Environment Protection Authority. 'However, we are conducting continuous water quality tests and have activated the National Oil and Hazardous Noxious Substances Spill Contingency Plan to remain prepared,' he added. Adding to the urgency, Indian authorities are battling another maritime emergency just two weeks after the ELSA 3 incident. On June 7, the Singapore-flagged container ship MV Wan Hai 503 caught fire following multiple explosions, approximately 88 nautical miles off the coast of Kerala. The vessel, carrying more than 2,128 metric tonnes of fuel and numerous containers with hazardous materials, poses a potentially greater environmental risk than ELSA 3. As of June 18, Indian Coast Guard reports indicated that the fire was under control. The drifting vessel has since been secured and successfully towed away. Nurdle spill The nurdles are highly persistent in the marine environment, as they can absorb toxic chemicals and enter the food chain, posing a risk to marine life and potentially humans as research on the aftermath of X-Press Pearl disaster proves. The parallels of these disasters with the X-Press Pearl disaster are striking. The 2021 incident released billions of nurdles into the Indian Ocean, contaminating beaches for months, killing marine organisms and disrupting fishing livelihoods. One silver lining is that a lot of research was conducted following the X-Press Pearl disaster, and this can be informative in tackling the ongoing episode of the nurdle pollution, Gunasekara said. Even today, Sri Lanka is fighting for adequate compensation, with legal proceedings dragging on in international courts. The echoes of that catastrophe now serve as a grim warning: unless stronger regional protocols and maritime safety measures are enforced, the region could be doomed to repeat history.

Recent shipwrecks off Kerala coast a serious threat to marine ecosystem, DG shipping tells Kerala HC

Kochi: The shipwrecks off the Kerala coast pose a serious threat to the marine ecosystem and coastal environment, according to an affidavit filed in the Kerala high court on behalf of the director general of shipping. The affidavit, submitted by Shitesh Ranjan, ship surveyor-cum-deputy director general (technical) in the office of the mercantile marine department, Kochi, was in response to the PIL filed by former MP T N Prathapan. The petition seeks a comprehensive compensation package for fishermen and other stakeholders affected by the recent shipwrecks off Kerala. The affidavit highlighted that adrift containers from the cargo vessel MSC ELSA 3 not only pose a navigational hazard but also constitute a grave environmental risk, especially considering the hazardous nature of some of the cargo. As per the cargo manifest, the vessel was carrying 13 containers of Class 4.3 dangerous goods under the IMDG Code, specifically, calcium carbide, which is classified as hazardous and environmentally sensitive. The wreck is situated at a depth of 51 metres near the Indian coastline, and the presence of bunker fuel in the sunken vessel heightens the risk of an oil spill. As of June 16, a total of 60 containers had been salvaged from various points of the Kerala coastline. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo Importantly, none of them contained IMDG-classified cargo. The affidavit also stated that shoreline clean-up operations are currently being undertaken by the Marine Emergency Response Services (MERC). Regarding the fire onboard the Singapore-flagged container vessel Wan Hai 503, the affidavit noted that the ship was carrying approximately 143 IMDG-classified containers, including hazardous materials such as flammable liquids, flammable solids, toxic substances, corrosives, and other dangerous goods. Additionally, the vessel carried around 2,000 tonnes of heavy fuel oil and 240 tonnes of diesel oil in tanks near the fire-affected zones. State seeks 77.08 crore as interim claim The state govt has sought an interim relief of Rs 77.08 crore in its first interim claim report, in connection with the capsize of cargo vessel MSC ELSA 3 off the Kerala coast. The claim includes compensation for the loss of livelihoods suffered by fishermen between May 25 and June 1. According to an affidavit filed by environment department special secretary Seeram Sambasiva Rao, Rs 54.93 crore has been claimed for livelihood losses, while Rs 22.15 crore has been sought towards the expenditure incurred in managing the aftermath of the incident. The affidavit further states that the first interim claim report will be forwarded to director general of shipping within three days.

India seeks tighter container safety, cargo disclosure norms in IMO meet

After multiple incidents of vessel sinking and fires off Indian coasts, India has asked the United Nations' International Maritime Organization (IMO) to tighten container safety and cargo disclosure norms on a 'war footing'. The development comes at the heels of IMO's ongoing session of the Maritime Safety Committee, where India brought up the recent sinking of the Liberian-flagged vessel MSC ELSA 3 and a fire aboard the MV Wan Hai 503, which, according to officials aware of the matter, has still not been completely extinguished. 'These incidents highlight urgent safety concerns regarding cargo carriage on container ships. India urges a global review of packaging, stowage, and monitoring protocols of containerised cargoes, especially lithium-ion (Li-ion) batteries and plastic nurdles. The four incidents in quick succession within three weeks demand immediate action from stakeholders to protect seafarers' lives and the livelihoods of Indian fishermen and coastal communities,' the Indian delegation said at the maritime watchdog's safety meeting. India's stand at the meeting is that reliance solely on shipper declarations is not adequate — a call made repeatedly in the past by sector watchers around the globe. Shipowners/managers, especially container shipping lines, must adopt technology and take responsibility to prevent such incidents in a transparent manner. 'What is in a box can't be a mystery anymore. India calls on the IMO to develop stronger regulatory mechanisms for the safety of container ships, cargo management, and crew protection on a war footing,' the Indian delegation said. According to reports, MV Wan Hai 503 was carrying flammable solids (IMO Class 4.1) in 20 containers — including extremely flammable nitrocellulose with alcohol in two containers, naphthalene (crude or refined) in 12 containers, and flammable liquids in multiple containers. The vessel is also carrying over 4,900 kilograms of a spontaneously combustible (IMO Class 4.2) organometallic substance, which can combust when in contact with air and reacts with water. On May 25, MSC ELSA 3 sank 30 nautical miles southwest of Kochi. It carried 13 containers with International Maritime Dangerous Goods cargoes. Local reports, however, show a continued flow of plastic nurdles on the coast of Kerala, which are being cleaned up by local authorities. The Singapore-flagged Wan Hai 503 suffered an underdeck explosion and fire. The vessel carried 147 dangerous containers. Firefighting and towing operations, coordinated by the Directorate General of Shipping, are ongoing to prevent ecological harm. Both these incidents have caused major environmental damage to coastal fishing communities in Kerala — 65 containers have fallen overboard, many yet to be traced. Two more incidents involving vessels with flammable substances have also taken place in recent weeks off the coasts of Mumbai and Kerala. Safety investigations are ongoing, and India will share the findings of these probes at the next meeting of the Maritime Safety Committee. While the next committee meeting is scheduled for May 2026, a meeting of the Marine Environment Protection Committee is scheduled for October. 'Though these incidents involved foreign vessels and crew from other nationalities, we activated rapid search and rescue and emergency response,' India said.
