14 | WATERLINE September 2026 FEATURE ENVIRONMENT, DECARBONISATION & SUSTAINABILITY KEEPING THE WATER CLEAN INSIDE ONE°15 MARINA'S APPROACH TO WASTE AND CONSERVATION WASTE MANAGEMENT AT THE SOURCE Ocean currents, weather systems and boat users all contribute to the waste that reaches the marina, so ONE°15 Marina takes a proactive approach to waste management to keep its water clean. Waste management methods employed in the marina include: • Collec’Thor waste collecting machines, which collect approximately 3,600kg of floating debris a year. • A waste pump-out service prevents blackwater discharge into the water, collecting more than 33,000 litres a year. • Waste engine oils from boats are collected for recycling, amounting to approximately 6,800 litres a year. • Balloons and confetti are prohibited in the marina and on charters. • Large volume recycling bins are placed at all marina gates to encourage boaters and charterers to recycle their rubbish before leaving. • Implementing penalties for littering and unauthorised fishing. Beyond waste management on water, the marina is working to reduce its carbon footprint through energy-efficient air conditioning and kitchen appliances, centrally controlled temperature management, energy consumption monitoring, and automated appliance shut off times. EDUCATION & COMMUNITY ENGAGEMENT One person can’t save the oceans, but many can. ONE°15 Marina regularly engages its members, volunteers, partners and the public through events that raise awareness of ocean and coastal conservation, including: • ·Annual marina/beach clean ups involving members, environmental groups and volunteers. To date, close to 800 volunteers have collected more than 600kgs of rubbish. • ·Coral Garden Tours, educating members and the public on ocean conservation and coral restoration. 480 visitors have taken part across 34 tours, including students, educators, volunteers, industry partners and seniors. • ·Complimentary berthing during Singapore stopovers for vessels sailing for environmental and humanitarian causes, including: - Energy Observer: a vessel that produces hydrogen via electrolysis of seawater and combines renewable energies to navigate the globe with zero direct emissions, showcasing the capabilities of renewable energy. - Planet Solar: the first boat to complete a round-the-world trip powered solely by solar energy. - Historical Vessel Vega: a 130-year-old vessel committed to humanitarian works such as delivering donated educational and medical supplies to remote island communities in South East Asia. - Blue Water Edufest: which uses cash prizes from donations, sponsorships and a charity auction to fund scalable environmental projects led by young people across South East Asia. - WWF Sharks and Rays Monitoring Project: a three-year donation through Blue Water Edufest is funding a WWF programme that surveys shark and stingray populations in Singapore waters, providing indicators of marine ecosystem health. A CONTAINMENT SOLUTION THAT CAN SUPPORT YOUR MARINA'S ENVIRONMENTAL CASE By Antoine Repiton-Preneuf, Business Development Manager Asia-Pacific & Americas, The Searial Cleaners For marina managers and fuelling station operators, environmental compliance is an ongoing concern, not just a oneoff hurdle at construction. Whether the goal is securing a new operating permit, renewing an existing licence, responding to a regulator's request for stronger safeguards, or simply reducing the environmental footprint of daily bunkering operations, being able to point to a proven, monitorable containment method makes the conversation easier. InvisiBubble, by The Searial Cleaners, is a submerged bubble curtain: a diffuser line on the seabed releases a continuous wall of fine air bubbles, creating a rising current that contains surface hydrocarbons and limits sediment resuspension. Because it stays underwater until activated, it leaves the quay and the water surface completely clear, with no impact on navigation, mooring, or day-to-day operations. THE SAINT-TROPEZ PILOT PROJECT InvisiBubble's first deployment in France was delivered in partnership with the Port de Saint-Tropez harbour authorities, at the Phare Vert fuelling station, one of the port's busiest bunkering points. A few details that may be useful for evaluating a similar installation: Location and scope: installed directly at an active fuelling berth, covering the containment zone around the point of refuelling rather than the whole marina basin. Integration: the diffuser line and air supply were routed through the quay's existing utility ducting, and the compressor unit was sized to sit within the footprint of the existing fuelling station infrastructure, no major civil works were needed on the quay itself. Installation method: the diffuser line was fixed to the quay wall and anchored to the seabed by divers, using concrete anchor blocks, a process that did not require the berth to be closed for an extended period. Operational impact: the curtain is only activated when there is an oil leak, so it does not run continuously and does not obstruct manoeuvring or mooring at any other time. Visibility: the installation drew media attention beyond the marine sector, with a French national broadcaster covering it as part of a wider segment on environmental practices in marinas. Beyond fuelling stations, the same principle applies wherever a marina needs a mitigation measure it can point to without giving up quay access, from dredging and construction works near operational berths, to sensitive habitat protection, to general bunkering zones.
